Things tend to break. Mobile phones are no exception in this regard. Sometimes the phone starts to show independence - it turns off and does not turn on. The main reasons for this behavior of the phone are as follows:
- battery malfunction;
- software failure;
- mechanical damage.
Phone software
Arbitrary turn-ons and shutdowns are more likely to occur due to software failure. The problem is being treated by changing the firmware. Experienced users will be able to change the firmware on their own. If you are not sure of yourself, it is better to contact the service center.
Phone battery problem
Another reason is battery problems. The first thing to do is to put the phone on a long charge, for 12-24 hours. If after such a cardinal charge the phone continues to be naughty, then we take a screwdriver and open the back cover. We check the contacts of the phone and battery. The contact between the battery and the phone may have loosened. Alternatively, they were damaged due to moisture or shock. We check for damage, carry out prophylaxis (clean the contacts with alcohol) and assemble the phone. Is the problem gone? We read on.
Damage to the phone
Rough handling, drops and shocks lead to mechanical damage to the board and other elements of the phone. This can also be checked. It is enough to bend the phone with your hands. If, after such a procedure, the phone freezes or turns off, it means that the reason has been found for a solution, it is best to contact the service center.
It is possible that the power amplifier is damaged in the device, which often happens after a fall. Such a malfunction leads to an increase in the amount of energy consumed, the result of which is the constant switching off of the phone.
Arbitrary switching on more often occurs due to the "sinking" of the power button (mainly in Nokia and Sony Ericsson models). As in the previous case, mechanical damage or leaked water can be the cause of the breakdown. In any case, with such a problem it is better to go to the service center.
