S23 ultra lag and video stutter

[Rio3505]

Got the s23 ultra it's not what people say it is. It stutters alot in games and apps and video is borderline unusable. Do I return it for a different brand or not

There is nothing wrong with the S23U. It's a brilliant device. It could just need a spring clean, especially if you've recently updated. In fact please ensure you have ALL the latest updates.

Try wiping the cache partition

You will need to plug into a working device or pc/laptop.

Also, consider reaching out to the game/app developers as they may need to make improvements to their software to make them perform better (it's not always down to the phone).

Feel free to do as you please with the phone. It's your money at the end of the day.

Thank you

Sorry to bother you again but how do you enter recovery mode to wipe cache partition? I tried powering on the phone while holding volume bettons but it just keeps vibrating randomly when I do that

[Robin999]

You'll need to plug into a working pc or laptop. With the phone powered off, Hold power button and volume up. When you feel the device vibrate and the Samsung logo appears then release all buttons. Once the recovery menu appears then use the volume up/down buttons to scroll to the wipe cache partition setting. Press the power button to confirm. Use volume up/down again to select yes and power button to confirm. Press power button to reboot.

Its all in the link.

I did it and sadly the video got slightly worse but thank you for the help!

[Robin999]

Worse!? That's a shame. You could also try booting in safe mode and see if you get video stutter. You won't be able to test your games though.

Long press power button. Long press power icon. Tap safe mode icon. Phone will restart in safe mode. Test video and report back.

Get the Good Guardians app from the Galaxy Store and within the app, install the App Booster. Run the app booster to optimise your apps. This is part of Samsung, so you're not using a 3rd party source.

Restart your phone and watch how smooth it will start to become.

I'll give it a try 👍

It did help a tiny bit but still laggy when I start recording
