Hi.

I recently updated software in my Samsung Galaxy S21 FE on 25.06.2025 and just now, i.e., 6.07.2025, I got a white line on my phone's screen. I never dropped my phone or used it near water. There is no wear and tear. It just appeared out of nowhere. Please get this issue fixed ASAP.

Troubleshooting Steps:

Restart Your Phone: A simple restart can resolve temporary display glitches. 

Check for Software Updates: Ensure your phone's software is up to date, as updates can sometimes fix bugs. 

Boot in Safe Mode: This mode limits apps to the essentials, helping you identify if a third-party app is the culprit. To enter safe mode: 

Power off your phone. 

Press and hold the power button until the Samsung logo appears. 

Release the power button and immediately press and hold the volume down button. 

Continue holding until the phone finishes booting into safe mode. 

Uninstall Recently Installed Apps: If the issue seems related to a specific app, try uninstalling it. 

Check for Edge Panel/One-Handed Operation: If you have these features enabled, they can sometimes cause a visible line. Check their settings to adjust the line's position or color or disable them. 

Run a Screen Test: Dial *#0*# in the phone app to access the service menu. Look for a screen test or color card option to see if the white line is still visible. 

Contact Samsung Support: If the above steps don't help, contact Samsung support or a repair professional. They can diagnose the problem and provide repair options
