Useful tips
Today, smartphones and other gadgets have become an integral part of our lives. With their help, we communicate with loved ones, watch movies, listen to music, and play games. And it seems that we have studied our smartphone inside and out.
But there are some important smartphone features that you definitely didn't know about.
But your smartphone is a real treasure trove of interesting functions and various useful options.
Hidden smartphone functions
1. Black wallpaper reduces battery consumption
Each of us has encountered an unpleasant situation when the mobile phone battery was discharged at the most inopportune and unexpected moment.
Some options help save battery consumption. For example, if you set your smartphone to a plain black background instead of a light or colored wallpaper, the automatic pixel lighting feature is disabled.
This way you extend the life of your gadget's battery. You will see that your mobile phone or tablet will work longer without any recharging.
Practice has shown that the phone's operating time increases by about 20-30 percent if the screen is constantly on.
This function works on so-called OLED displays, which are equipped with many Samsung models.
If you don't know what type of display is on your mobile phone, ask the search engine for a hint: just enter the phone brand, in the characteristics - display type and find out what type you have.
2. Remote control via smartphone
Just go to Settings -> Security -> Device Administrators and check the boxes next to the Android Device Manager option.
Remotely locate this device, allow remote locking and erasing. Now, if you lose your smartphone, you can easily locate it and block it without losing any data.
3. Control your phone by moving your head
Sometimes situations arise when you need to quickly use your smartphone, but your hands are busy or dirty, or it’s so cold outside that you don’t want to take off your gloves to press the keys.
What to do in such cases? There is a solution!
You just need to install the free EVA Facial Mouse application on your smartphone, which is suitable for any Android device.
With this simple application, you can control your mobile phone using simple head movements.
4. Secret video shooting
Sometimes a situation may arise when it is necessary to film a video, but without anyone knowing about it.
You can use your iPhone for this. So, follow these instructions: you need to lock the screen, then turn on the camera by simply pressing the button and using your fingers to raise the shutter up.
Activate video mode, start recording. It is important to keep the display half-locked and then click on the Home button 3 times.
You must wait until the screen goes completely dark. That's it, video shooting has already begun.
5. Badoo (People nearby)
Agree, it’s always interesting to know what kind of people surround you at the moment. Who are they, what are their names, what age are they and, of course, what are they interested in?
For example, you see an attractive girl or a handsome guy in a cafe or just on the street. However, not everyone will decide to approach.
What if you could send a message to this person or like a photo you like.
It is for such situations that the Badoo app exists. It detects people who are in your immediate vicinity.
A clear example of how the application works: setting a limit "Girls from 20 to 25 years old" and see what the search engine gives us. Then we look at the photo and choose the one that caught our attention.
If desired, you can like the pictures, send an emoticon to the user, and the bravest ones can even send a message.
If the object of your affection responds to your message, you start a conversation, and after that you can not be afraid to make an actual date.
It is worth noting that this is a free application that is supported on all platforms. You can download it on Android, iOS and even Windows Phone.
6. Access to private notifications
Many of us are faced with the fact that we regularly receive many different notifications. This happens because there are a huge number of applications installed on our smartphones.
However, most of these notifications can be safely classified as spam, since they are absolutely unnecessary and useless.
As a rule, you immediately close unnecessary notifications, but sometimes one careless movement is enough to delete or close an important message, which is then difficult to find.
In such cases, the Past Notifications application will help you. With its help, you can easily view closed notifications.
This application allows you to delete selected notifications or blacklist unwanted programs, and mark unwanted notifications as spam.
This way you will be less distracted by notifications that are absolutely useless.
7. Text-to-Speech Function
So, if you don't want to strain your eyes and prefer to listen to incoming information rather than see it, go to Settings -> Accessibility and simply turn on the option Text-to-Speech.
8. Activate guest mode
If you have a situation where you need to give your smartphone to someone else for temporary use, but you don’t want anyone to rummage through your phone, you can activate guest mode.
With its help, you will keep your personal data confidential. Simply swipe down with two fingers and tap the user icon in the top right corner. After this manipulation, the “Add Guest” icon should appear on the screen, and you yourself choose what actions the person controlling your smartphone will perform.
What can your smartphone do?
9. Screen magnifier
A screen magnifier will be a real lifesaver for people with poor vision.
Many people don't even realize how useful this feature can be. Just go to Settings -> Accessibility -> Zoom Gestures. And that's it, you can enlarge any part of the display by simply clicking on this screen enlarger.
10. Hotspot mode
You no longer need to buy a separate 3G modem or router to use the Internet on different devices because your smartphone can easily handle the task.
Go to Settings -> Tethering and Portable Hotspot, activate Portable WLAN hotspot. All is ready!
In the technical characteristics of modern phones you can see the presence of a new function. NFC function on the phone - what is it? We will try to answer this question in this article.
The concept of NFC technology
When we decipher the abbreviation and translate it, we get that NFC means “near field communication.”
This technology originated at the beginning of the 21st century. Sony and Philips began to develop it, independently of each other, which contributed to the fact that their developments were incompatible with each other. Subsequently, efforts became joint, which ultimately made it possible to begin implementing this technology in 2004.
So, let's get down to analysis: the NFC function on the phone - what is it?
This technology is mainly used for multi-use contactless cards. With its help, you can pay for travel on public transport, get an electronic pass, make payment transactions, etc.
This function is similar in its manifestation to Wi-Fi and Bluetooth, but its communication speed can reach 400 kbps, while the range of action is only 10 cm. On the one hand, this is considered an obstacle for attackers, but on the other hand, it is poorly protected from data interception and relay attacks. The connection is established in 0.1 seconds.
Today, this function is usually not built into inexpensive gadgets, which slows down its spread, since it is inexpensive models that are in wide demand.
There are quite a few devices that support an antenna for this technology. NFC tags are objects with corresponding chips that receive energy from interaction with smartphones.
Using NFC
So, we have figured out a little about the answer to the question “NFC function on the phone - what is it?” Let's see where it can be used.
You can use it to pay for purchases and bills. NFC adapters are installed in many terminals in cafes and shops. A phone equipped with this feature rests its back cover against the tag on the terminal for a few seconds to read the data, after which the transaction is completed. When using this function, you can create a virtual card in a few clicks, which can be used to pay for goods or, for example, travel on the subway. This will eliminate the need to use various other bank cards in everyday life as they can be scanned using this module and then used using the phone.
In addition, using this function, you can exchange data between various gadgets that have it or that have an NFC antenna and tags, which will be discussed below. Using this function, phones are identified, and further data transfer is carried out via Wi-Fi direct or Bluetooth. Data exchange is carried out at speeds quite high for mobile devices, the connection is made by touching the backs of the phones.
Also, using this function allows you to “distribute” the Internet when sticking a tag in a certain place. If you turn off Bluetooth, Wi-Fi, and mobile data at night and set it to silent mode, then in the morning you need to turn everything on again. If you have a tag next to your phone, this process can be automated. If you stick a tag somewhere on the car, you can automate the process of turning on GPS, transferring mobile data and opening the navigator. You can configure the laptop to turn on when it detects activity of wireless networks, that is, in order to turn it on, you do not need to press a button - you just need to bring a phone that is equipped with the technology in question to it. If your guests have phones with NFC function, then they may not ask you for the Wi-Fi password, since you just need to bring the phone to the tag and access to the Internet will be provided (the usefulness of this method is quite doubtful, since the person will need to be present at all times while using The Internet is near the mark, and if several people use it in this way, this will create certain inconveniences). By sticking the tag to a Bluetooth headset, you can automatically listen to music when you put on the headphones. Carrying out these actions requires programming the tags, but all this can be done using special applications.
This technology is used in electronic keys, identification cards, and when purchasing electronic tickets.
How does the NFC function work on your phone?
The principle of NFC operation comes down to the conversion of electromagnetic waves. There are active and passive NFC tags. The former require an additional power source and management; with their help, they transmit any signals. The latter do not require a power source, but transmit a signal that is initially programmed.
The circuit of such a tag: an external magnetic field is detected by a diode, after which the signal is sent to the reading device.
When two gadgets are brought close to each other, the tags begin to be detected among themselves, resulting in identification and further processes characteristic of the NFC function.
What devices can this technology be found in?
Today NFC can also be found in Chinese phones. The introduction of this feature is similar to the introduction of the fingerprint function, which was initially present only on ultra-expensive models, and then became widespread.
Here is a small list of phones with NFC function. This includes Samsung 7th generation phones, J5, Sony Xperia XZ and XZ premium and others. Among inexpensive phones, Blackview BV6000S, Nokia 3 Dual Sim, Sony Xperia L1 are equipped with this function.
Phones from previous years that have the NFC function include LG G3, Samsung Galaxy S4, Huawei P8 Lite, Elephone Vowney, Hauwei Honor 4C.
Phones with NFC from Samsung
The NFC function in Samsung phones works with the following models and modifications:
- Galaxy S8 is a model running on Android 7.0 OS. May include two SIM cards, although the phone only has one communication module. Screen size - 5.8 inches, resolution - up to 2960 x 1440. Camera resolution - 12 MP, has autofocus.
- Galaxy A5 - this model belongs to the budget, OS "Android 6" and higher. Work is possible with two SIM cards. Screen diagonal is 5.2 inches, resolution is 1920 x 1080. Camera resolution is 16 megapixels, there is autofocus.
- Galaxy S7 - OS "Android 7.0", it can also work with two SIM cards. Screen diagonal is 5.1 inches, resolution is 2560 x 1440. Camera resolution is 12 megapixels, autofocus is present.
To ensure data transfer, you need to activate the chip. Go to the menu “Settings” - “Advanced” - “NFC enable”. After performing this action, Android Beam technology, which is responsible for NFC, should be activated. If this does not happen, then in the same menu you need to click “Enable”. Full operation is ensured when both technologies are enabled. Connected devices must not be locked or turned off. When gadgets are detected, a vibration signal is sent, after which data is transferred, during which there is no need to disconnect the devices, as this will lead to the loss of the transmitted information.
Xiaomi phones with NFC function
Here is a list of gadgets produced by Xiaomi that have a built-in NFC function.
We will form this list from cheaper to more expensive models.
- Xiaomi Mi4 3/64Gb - Android 4.4 OS. Screen diagonal - 5 inches, resolution 1080 x 1920, micro-sim, main camera resolution - 13 MP. Cost 11500-13500 rub.
- Xiaomi Mi3 64Gb - Android OS. Screen diagonal - 5 inches, resolution 1080 x 1920, micro-sim, main camera resolution - 13 MP. Cost about 15,000 rubles.

Thus, Xiaomi produces NFC-enabled phones in many models ranging from Mi2 to Mi6.
Determining whether the technology in question is used on your phone
How to check the NFC function on your phone? This can be done in two ways.
You can look at the battery by first removing the back wall of the phone. If the phone supports this technology, a corresponding mark must be made on the sticker.
Or using the menu: “Settings” - “Wireless connections”. If the phone is capable of working with the technology in question, there should be an NFC item here that needs to be enabled, and Android Beam should be automatically activated. Thus, we figured out how to find the NFC function on the phone.
It can be noted that the implementation of this technology began after the release of the Android 4 OS. This is done through the use of the Beam function. You may not immediately see any mention of NFC in the wireless networks menu; try clicking on the “More” button.
NFC antennas and modules
If this technology was not detected in the phone, this does not mean that it cannot be connected. How to enable NFC function on your phone?
To do this, you need to install an NFC module. This can be done by purchasing a SIM card with a built-in NFC chip, which will be used in your phone. In addition, the phone can be equipped with a corresponding antenna, which is glued to the existing SIM card and placed under the cover.
We pay using the function in question
NFC tags and chips can be found in absolutely any product - bracelets, stickers, stickers, etc. Data is read using applications designed to carry out these operations.
To set up your phone so that you can use it to pay for goods, you need to install the Visa QIWI Wallet program, and then link your account to your wallet via SMS. This program will check for the presence of the corresponding module in your phone and, if detected, will offer to coordinate with it.
Finally
The article addressed the question: “The NFC function on a phone - what is it?” Modern technologies are aimed at making people more and more lazy. For the most part, NFC technology is aimed at this, which allows you to automate many processes. One of its useful features is paying for goods using your phone. However, if you lose a gadget with configured payment systems, it will allow the person who found it to make your account zero, so everyone must decide for themselves whether they need it or not.
Phonebook. This function is a necessary and mandatory thing for any mobile phone. Available in all modern devices. Allows each phone number to have its own unique name. For example, 8-888-888-88-88 - Ivan Petrov. Contacts can be saved in the phone's memory, an additional memory card or a SIM card. Concepts such as “memory card” and “sim card” are discussed in paragraphs 15 and 19, respectively.
More advanced devices have the ability to save a lot of useful information for each contact (email address, home and work phone numbers, place of work, home address, etc.). In this case, the phone functions as a full-fledged address book. mobile phone smartphone market
Call log. The function is extremely useful. Makes it easy to see where and when you called (or were called). Also, using the call log, you can see the duration of any of your calls. Today this function is present in every cell phone.
SMS(Short Message Service - short message service). The same absolutely mandatory service today as the previous two. Allows you to send and receive short text messages over cellular networks. Today this feature is present even in the cheapest models.
MMS(Multimedia Message Service - multimedia message service). This function allows you to send and receive multimedia messages (video, audio, pictures) from one phone to another. It should be noted that the size of the transmitted content is quite limited. Most cellular operators in Russia and the CIS allow you to transfer up to 300 KB of information in one MMS message. Today, the largest cellular operators allow you to send SMS and MMS from their websites for free. You only need to pay for Internet services.
Watch. Today, it is perhaps impossible to find a cell phone that lacks this function. Although, of course, if you want, everything is possible. After all, phones come in every taste and color. A clock is a useful, simple, necessary function. At the same time, no one forbids you to wear your favorite wristwatch.
Stopwatch. What it allows you to do is clear from the name. Stopwatches in modern phones are quite accurate. The function is useful for athletes. May be useful for students during laboratory work.
Timer. The opposite of a stopwatch. Allows you to count down time “backward”, do a countdown. You select a time interval and turn on the timer. At the end of this segment, the timer gives a certain signal (sound, vibration).
Alarm. This function can be used instead of a regular stationary alarm clock. Or as another, safety alarm clock. A very convenient thing. Especially when you are visiting and you need to wake up early in the morning.
Calendar. Useful feature. Often you don’t have an ordinary calendar at hand at the right time. And you need to look at what day of the week it will be, for example, April 10. A couple of quick clicks and you're in the know. Very comfortably.
Calculator. Most often, phones have a simple (non-engineering) calculator installed. It is suitable for some quick simple calculations. When you need to add, subtract, divide, multiply or take a percentage. Having this feature can be really useful. After all, an ordinary calculator is not always available where it is needed now. Today this function is present in almost any mobile phone.
Converter. Allows you to convert various quantities (units of volume, area, length, etc.) from one measurement system to another. This also includes the ability to convert one currency into another at a rate known to you.
Radio. Allows you to listen to publicly available radio stations operating on FM frequencies absolutely free of charge. A necessary function for those who want to constantly stay up to date with events. Who likes to listen to news and favorite programs on the radio.
Flashlight. It will be very useful when you don’t have a regular flashlight at hand. And you will definitely need to highlight something somewhere. You can, of course, highlight it with a bright switched-on display. But a flashlight in this case is much better. Shines brighter, white light. Moreover, unlike the display, it shines pointwise, and not “smeared”.
Photo, video camera. A most useful feature. Present in most modern mobile phones. Sometimes you don’t have a camera or video camera at hand, but you urgently need to capture something. Even if not in the best quality. Although one can argue about the quality. There are phones in which the main emphasis is on the extensive camera capabilities. Such devices allow you to obtain photos and videos of very decent quality. Such phones are called camera phones. An example of a camera phone is the Samsung Pixon M8800. It is equipped with an 8 million pixel camera. with LED flash; maximum photo resolution 3264x2448 pixels.
Memory card support. In cell phones, various information (your contacts, audio, video files, photos) can be stored in the memory of the device itself. However, most often the amount of this memory is very limited. Although there are devices with quite decent internal memory. To expand memory, phones are usually equipped with connectors (“slots”) for special memory cards (flash cards or “flash drives”). There are different types of memory cards. Today, the most common slots in mobile phones are microSD and microSDHC flash cards. The former allow you to store up to 4 GB of information, the latter - up to 32 GB.
MP3 player. For music lovers, this function is simply irreplaceable. Allows you to listen to audio files available on the phone (or on the inserted memory card). Moreover, the most advanced phone models in this regard reproduce sound not only in mp3 format. They support AAC, WMA, WAV and some other formats. Devices in which the main emphasis is placed on increased quality of reproduced sound are called “musicphones” (music phones). An example of such a phone is Nokia X6.
Dictaphone. Useful feature. Imagine: you need to record it, but you don’t have time to write it down. Or just lazy. It’s much easier and faster to click the “record” button and save the desired audio file. It is very convenient to record some kind of conversation or conversation. This function will be useful for musicians. You never know where inspiration will come to them. He turned on the recorder and recorded the music he had composed, a vocal part or a song. Fast, simple, convenient.
Internet. Most modern phones allow you to access the global network. Today there are four main options to get online. These are WAP, GPRS, Wi-Fi and 3G. We will not dwell on each of them in detail. This is a separate big conversation. Note that the most popular in Russia today is GPRS. Although this is not the fastest option for accessing the Internet. WAP technology in the form in which it exists today is not promising. Too expensive and slow. Moreover, you need to pay not for the amount of information viewed (as in the case of GPRS), but for the time spent on the network. Wi-Fi will certainly not be an unnecessary feature in your device. It allows you to surf the Internet at high speed. However, for Wi-Fi to work, special access points, so-called hotspots, are required. They are paid and free. The latter are most often found in various public places. Where there is a constant crowd of people (cinemas, bars, cafes, etc.). It should be noted that their number in all major cities of Russia is growing. 3G is a technology for high-speed mobile Internet access, the so-called third generation mobile communications. Based on the definition, it is clear that the data transfer speed is even higher than in the case of Wi-Fi. This service in the Russian Federation is under development. Moreover, this development is proceeding at a fairly rapid pace. It is quite possible that the 3G feature will soon become very popular among mobile phone users in our country.
“Multi-SIM”. This term refers to the ability of the device to simultaneously work with two or more active SIM cards.
Each mobile operator issues you its own SIM card for one phone number you purchase. In this case, you yourself choose the tariff at which you will pay for your mobile communications in the future. Of course, each operator has its own conditions (communication prices), its own set of tariffs. It changes periodically. A clear question arises: what is actually good about the function in question? What’s good about it is that it allows you to simultaneously be in touch on two or even three different phone numbers. After all, today there are phones that support three active SIM cards at once. In this case, the numbers can refer to both different cellular operators, and to one. Accordingly, you get the opportunity to “play” with tariff plans. You can choose the most profitable communication option. And in this case, it is enough to have just one turned on mobile phone with you. An example of a phone with two active SIM cards is Samsung SGH-D880.
Java support. This feature allows you to install various games and applications on the Java platform on your phone. For those who like to communicate via the instant messaging service ICQ, this is a must-have. Moreover, “Asya” allows you to communicate many times cheaper than the SMS short message service. Those who like to play all sorts of racing games, shooters, mini-quests, etc. on their phone cannot do without java support.
Possibility of connecting to a PC (data cable). Allows you to transfer various files from your mobile phone to your computer and vice versa. Today, phone manufacturers release special programs for their devices. These programs allow you to do many useful things with your phone. They are installed on your computer. Then connect the phone to the PC (using a special cable). Now you get the opportunity, for example, to create backup copies of data from your mobile phone. In addition to this, a number of other interesting opportunities appear. The function is definitely the most useful.
IR port. Infrared port. The technology allows you to transfer data from one device to another. This happens through infrared light waves. Today this technology is almost completely replaced by other, more advanced ones (Bluetooth and Wi-Fi).
Bluetooth. This technology allows you to exchange various information between mobile phones, PCs and other devices on a specific radio frequency. You should know that for such an exchange, the distance between devices should not exceed 10-100 meters (it depends on various interferences and obstacles). Quite a convenient feature. Available on most modern mobile phones.
TV tuner. TV on the screen of your mobile phone. In Russia today this function is poorly developed. The reason is the high cost of receiving a high-quality signal. However, in the world of mobile communications, nothing stands still. It is quite possible that in the near future the situation will change. And with the development of new technologies, we will watch television programs on the screens of our phones. An example of such a phone is the Samsung P960.
GPS. Satellite navigation system. Allows you to determine your location anywhere in the world with sufficient accuracy (error 1-2 m). A mobile phone that has this function and is equipped with a special program turns into a navigator. A useful feature for traveling and long trips.
Why are more and more mobile manufacturers equipping smartphones with an NFC chip, and what opportunities does this technology open up for the user?
Nowadays, the mobile market offers a wide variety of high- and mid-price smartphones that are equipped with an NFC chip. Before you pay for an additional function, you need to understand what it is and why it is needed in the phone.
What is NFC?
NFC (Near field communication) is a wireless communication interface, one of the main characteristics of which, as the name suggests, is a short range (up to 10 cm). Among the features of the technology we can also highlight:
- Possibility of exchange with other devices and passive tags.
- Compact sizes.
- Low power consumption.
- Low data transfer speed.
- Connection setup time is 0.1 seconds.
- Budget cost.
Thanks to its small size and low power consumption, NFC can be used in small devices. In smartphones, the antenna is usually mounted on the battery compartment cover or the inside of the back panel if the battery is removable. So that users do not have the question of how exactly to apply the gadget to transfer data (this problem is especially typical for tablets due to their large size and short range of technology), the location of the chip is often marked with a special sticker on the case.
Since the NFC interface is only a base that does not provide a clear solution for use, mobile manufacturers and application developers have to independently develop work scenarios. This can cause problems when apps and devices from different manufacturers interact with each other.
Ways to use NFC
Perhaps one of the most common ways to use NFC is. The user can attach a bank card to their mobile device, with which they will pay in the future, for example, if the card is left at home. In this case, the possibility of data interception is extremely low due to the small range of the interface; a lost or stolen unlocked smartphone poses a great danger.
To make a payment via NFC you will need:
- Bank card marked paypass.
- Application of the relevant bank.
- Find the NFC item in the application menu.
- Place the card on the back of the phone to read it.
- Remember the password for payment transactions sent in an SMS message.
The next method of using technology is data exchange. Using the Android Beam program, you can transfer various files from one mobile device to another. However, the transfer speed is very low, so this function is more suitable for sending small text messages and links.
Instructions:
1. Activate NFC - check the box next to this item in the “Wireless Networks” menu, unlock your smartphone and turn on the screen.
2. Select an agent:
- Google Chrome - to transfer the current active link.
- Google Maps - for transferring the route.
- Google Play - for transferring applications, books and other content presented in the service.
- YouTube - to send a link to a video.
- Contacts - to transfer a contact.
- Gallery - for transferring photos and pictures (however, this can take a long time due to the low transfer speed, so in this case it is better to use special applications, which will be discussed below).
3. Bring the devices closer until the alarm sounds.
4. Touch and hold the screen to confirm the transfer.
5. Another beep will sound indicating successful file transfer.
There are various applications that use the NFC interface only for pairing, and subsequent file transfer is carried out via a Bluetooth or Wi-Fi connection: Send! File Transfer, File Expert HD and Super Beam WiFi Direct Share.
The next method is reading and writing tags. This function works similarly, only the NFC chip is used rather than the smartphone camera. It can be useful for automating home and work life. To create your own, you will need blank blanks and special programs for recording the necessary information. You can assign the following actions to a tag, which will be performed after it is read: sending an SMS message or email, calling a contact, opening a link, connecting via Bluetooth, launching an application and much more.
Several programs for creating tags:
- WiFiTap WiFi NFC - for connecting a wireless network. Helps guests connect to a Wi-Fi hotspot quickly and without entering a password.
- ABA NFC - for creating various standard format tags.
- SmartTag Maker is a special application for users of Sony products, which contains a number of templates used not only with the NFC interface, but also with a headset, Bluetooth devices, power supply, etc.
Bottom line
Each user decides for himself whether he needs the additional NFC function in his smartphone or not. However, this technology is being used in an increasing number of mobile devices. Therefore, if you did purchase a gadget with NFC support, you now know how to use all its capabilities to make life more convenient.
