I have the same problem with my phone right now. i seriously don't know what to doo about it either. My friend told me to take my phone apart for a while and then put it back together but it didnt work. I did drop my phone earlier but idk if it is the reason why it started doing that. It's been going up for a while. I'm gonna try some stuff with it and see if it works. itf it does i will try my best to help you.
