S4 charging but no lightning sign
Hello guys. I have been using s4 GT-I9500 since its launch and it has been fantastic so far.
I have it rooted and it works perfectly for almost 4months until last week.
Since last week, my phone could not detect when it was charging. When I put on the cable nothing happened (no lightning sign on battery bar above). But if I just leave it at there, the battery will charge until full.
Same thing happened when I put it on the USB to connect to PC. Nothing happened. The PC wont detect it (It has been working perfectly well before). But if I leave it there, the battery will still charge.
Anyone have any idea or have the same problem as me? I have tried restore to factory setting but it doesnt seem to work. I would like to unroot it but since I cant connect it to USB, that opton is not available to me.
Thanks in advance
