My phone is not turning on. Before I sleep in the afternoon, I had my phone charged. I woke up at 4pm, still working but since it has been fully charged, i unplugged the charger and kept my phone and I slept. When I woke up around 8pm, I just had a blank screen, not doing anything, not even turning on. I tried to remove my battery and put it back, still not turning on. Then i tried to charge it again for 20 minutes, still not working. I didn't even see my light indicator on. After couple of days, I tried to turn it on. Still not doing anything. I don't know what to do now. I think it's overcharged. I need a help here. Thanks!
