My phone would sometimes spontanously freeze and switch off, showing the 3 red leds and just stops responding. It won't even take a charge. Usually the battery is at 60% when the phone dies, and sometimes it shows a constant RED led.
The back cover is loose (but has enough adhesive to actually stick reasonably, takes little force to open it up), so I pressed that connector with medium force. The next thing that happened, is that the phone responded to the charger, booted to the "charging state", where it shows the battery state and so on (which it shows it's approx on 60%.
Or could it be that I press something else, which causes my phone to work properly again?
