Hi all, I downloaded an apk file (Plant V Zombies) and tried to Install (had very little amount of space left on phone). During installation phone just turned off (had 50% charge). I pulled battery than plugged in, it showed Samsung logo, loading bar and then turned off again. Now phone doesn't turn on nor charge. Tried hard reset by holding power and volume down or power and both volumes. Nothing. What could be the problem? Please help, appreciate it very much.
