In my case, before it start to happens, the colume buttons seems not working very well. Then it worsen where I cant turn off my screen when pressing the power button, but it still detects the fingerprint. Then I press the power button withvintentention to restart but it straight away goes soft reset as if I'm pressing power + vol button. I cant turn onthe phone anymore. The screen will turn on when I plug itbto charger,and it will display battery charging icon. But if I try to turn it on it will vibrate 3 times and it will strqight away turn-off just like soft reset.
