Hello!
This problem appeared more than once, among the owners of this phone. Replacement or repair of the motherboard is necessary. Judging by the fact that it was possible to find out in the service center, with the diagnosis - a problem in the power controller/voltaje regulator - dies.
Symptoms:
When charging, the red light is on constantly. Charging time any - does not change color. No reaction to the power button and long charge. For a long press of the power button - there is no reaction.
Result:
The reason for the failure of the motherboard is not precisely determined, it probably comes from the fast charging that comes with the phone. The phone is very warm during charging. After repair of the device, on the recommendation of the service center (not official Umi, it is not in our country) switched to standard (not fast) charging 5V 1-2A |
