Odd flicker/jitter when selecting something in any app

[TeaAri]

This has been happening after the Galaxy Note 20 Ultra 5G security update in August 2024. And ever since then I've been a little concerned about it since it occurs in every app in my phone.

(It's basically a little jitter/flicker that happens on my screen.)

I've tried clearing my cache, and rebooting/restarting my device hasn't worked.

If you have a similar problem or can try to help me, please let me know by typing in a comment. Thank you.

It looks Stretched.

Hello TeaAri, Welcome to the Community. We understand the concern with the flicker/jitter and stretched looking text in the apps.

Have you tried resetting the app settings? Phone Settings>General Management> Reset > Reset all settings

This does not remove your data, but will reset the apps. You will also need to reconnect to Wi-Fi and Bluetooth devices.

You can also try testing the phone in Safe Mode to determine if there is a 3rd party app causing the behavior. https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/

Let us know if this helps.

Both options do not work.

Thank you for confirming those steps. The remaining troubleshooting would be to try a factory reset. https://www.samsung.com/us/support/answer/ANS00062029/

You can also try submitting an error report in the Members app: https://us.community.samsung.com/t5/Tips-Tricks/How-to-Submit-an-Error-Report/ba-p/3001692

If the behavior continues, we recommend having the phone evaluated by a certified technician. You can use the following link to find a list of service centers in the U.S.: http://www.samsung.com/us/support/service/location or by calling customer support at 1-800-726-7864.

When is the next Samsung Galaxy Note 20 Ultra 5g system/software update.

There are no more system updates for the Note 20 Ultra. Your service provider may push a security update. You would need to reach out to them to see if they are continuing security updates for the phone.
