White Line on Screen After One UI 7 (Android 14) Update – S21 FE

[waseemj984]

Hello Samsung Members,

I wanted to share a frustrating issue I’m facing with my Galaxy S21 FE. Around 14 days after updating to One UI 7 with Android 14, I noticed a white line appearing on my screen. The phone was working fine before. I simply placed it down at night, and when I woke up the next morning, the white line was there.

I’ve tried all the usual troubleshooting steps (safe mode, display test, restart, etc.), but nothing has worked so far. This has really disappointed me, especially since my device is otherwise in good condition.

If this is a common issue after the update, I hope Samsung addresses it soon. If it's happening deliberately or due to software pushing hardware issues, it’s not acceptable.

Is anyone else experiencing this? Any suggestions or fixes would be greatly appreciated.

Thanks.

• The same happened to me today. I too have an S21 fe. After updating to one UI 7 running on android 15 with may month security patch, I got white line on my phone screen when I woke up and unlocked my device in the morning. I tried restarting but it didn't work.
