Overheating on start and not displaying anything meaningful

[Bernard Yu]

My mobile was fine last night. Until this morning, i found that my screen was not showing meaningful things anymore, just some white and green lines. Also, my mobile was overheated. It was not related to the battery. When i restarted, the right upper corner of my mobile got super overheated just in a second, and still did not show anything meaningful. Does anyone know what happened with my lg g5?

Welcome to Android Central! That sounds ominous.:-\ Does it boot up in Safe Mode? https://support.t-mobile.com/docs/DOC-30620
