I was charging my phone and it has already reached about 98%. Took it to reply a chat, only for me to drop it and check my phone back. Discovered it powered off and was showing up the flash Bolt sign on the battery like it wanna charge. But it's not showing up the battery bar percentage. I tried switching it on but to no avail. I removed it from the power outlet. Plugged it to my PC and it sounded as it was plugged. But still won't power on and stuck at the battery Bolt Flash sign. Am so confused right now and don't know what to do.
