Blue and white vertical lines on startup, then shuts down
Hello guys, first time questioning things here!
When I turn the phone a thumbs width blue and a little white vertical line appears on the middle of the screen and then it turns off.
My friend said it appeared when the phone ran out of battery, also says it didn't fall on the floor.
Things I've tried
- Plugged out battery, motherboard and all cables
Is this a good question?
