The screen is shaky and glitchy. It occasionally does a split screen or has vertical white or colored lines. It’s worked fine tho morning. I put it in my pocket, five minutes later I pulled it out and it was a blank screen. Eventually it got to where it is now.
It sounds like it needs a new LCD. It’s usually caused by a drop or if it’s had some sort of pressure on the screen. Luckily most LG lcds are pretty inexpensive.
It may be pressed in your pocket and you don’t know.
