Well last night i was playing with my phone, everything was ok, never had this problem before. And when i waoke up my phone was turned off, when i fell asleep the battery was about 40-50%, and now it won't turn on at all. Doesn't react to charging, i tried connecting it to my pc via USB cable, the PC actually recognized the phone and started installing software for it, which was already installed before..., and then said there are drivers to install. Now I'm at a standstill, I don't know what to do. Please help.
