Since this morning my phone (LG E900) restarts about five seconds after connecting or unplugging the USB cable to charge. The sound effect that usually plays when starting to charge is also missing.
I dropped it a few days ago (probably for the third or fourth time) but I'd guess if it's related to the fall then it would started happening directly and not days after it. Otherwise I left a GPS tracking app open over night and the battery was depleted this morning but that too has happened before. Any idea what might be responsible?
(I apologise for the poor tagging, but I'm not allowed to use new tags.)
EDIT: Neither updating the phone software, nor rolling back the update, nor re-updating, nor resetting it to factory settings helped. I'll send it in for repairs now.
