so i have had this phone for about 3 years and this year for some reason has been acting up. when i will take it out the phone will turn off and on for no reason. which was normal for me, i didnt really care as long as it would turn on again. But today my phone would not respond at all! i tried turning it on so many times but no response. so i tried charging it and i charge it from my computer and all it does is flash back and forth LG. after a night of charging i take the plug out and becomes unresponsive again. I have no idea what to do now any advice?
