Solved G3 need to get rid of small copy of screen visible on main screen.

[mahaneyrobkathie]

I have a LG G3 I just replaced the screen on. When I powered it up the is a small copy of the screen that appears on the screen and it won't go away. It is always there no matter what screen or app I am in.
Any ideas on how to get rid of it?

Is it a duplicate of the screen you are on or always that home screen? Where did you get the screen from? Why was it replaced? What kind of damage was done to the phone? Looks like a hardware issue to me but we need more information

The phone got dropped and cracked the front screen. I got the G3 Replacement LCD and Digitizer Assembly with Frame from repairpartsplus.com

The phone is a G3 not a G4.

Title changed to reflect which device.

This is a strange situation for sure.

Something either went wrong with the device hardware other than the screen breaking, or something...

My thought is there is something wrong with the main board in the phone.... I would contact the seller with the above photo and see if they would be willing to send a new set up again to rule that out... Check all cables and connections inside the device is another thought.......

I discovered one more thing. The mini image has the image size embedded in it.

Do you have developer options turned on by any chance?

Bingo! Secondary simulated display was set to 1280×720. Set it to none and it disapeared. Thank you!
