hi i just wanted to ask if my phone was infected by a virus. after i unplugged my charger, on my phone still prompts "charging". so i just ignored it. but after a few hours i noticed that my phone is hot so turned it off to restart. but when im trying to switched it on, the phone would not open anymore. so I still need to plug the charger before i can open again my phone and the same thing happens when i unplugged the charger. pls help. thanks!!
