Sometimes it is difficult to distinguish a hardware failure from a software one. In order to understand that the phone is turning on, it is enough to see that the LED lights up when the phone is booting up - consequently, the phone showed signs of life.
Relatively rarely, this is due to a breakdown of the phone's matrix; more often, such a malfunction is due to a software failure. Among the forerunners for such errors is the installation of incompatible software, applications from unreliable sources, add-ons, as a result of which Android does not turn on.
