Galaxy S21 Ultra Front Facing Camera 5G interferance

[iamJoel19]

The S21 Ultra has a serious problem on the front facing camera. Using 5G network, particularly on SIM 2, causes interferance with the front facing camera and causes it to have lines and streaks both on the preview and captured image. 

To test this out:

- Insert a SIM card in SIM2 slot

- Use SIM2 for mobile data and make sure you are on 5G

- Open up a camera up that uses data (e.g. FB call or Tiktok)

- Use the front facing camera and you will notice streaks and lines on the image (see sample shot below)

Is this a design flaw? What is Samsung doing about this?

Just wondering - is this isolated to data use on SIM2 or does it also happen on WiFi?

[iamJoel19]

So far it only happens when using sim2 on 5G.

it could be the camera or lcd problem thats one of the reason a line shows on the picture. did you try wipe cache partition or reset factory settings. or else go to the nearest repair services and have your warranty show.

Definitely not a camera or Lcd problem. I have 2 ubits experiencing the same issue and there is also an ongoing forum on Samsung members global regarding this issue. Samsung has yet to acknowledge it though.
