I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
My Device- S21 Ultra 5G ( SM-998B/DS ) CSC= BTU , 12GB/256GB
One Ui 4.0,Android 12 Official Version.
So I can't downgrade to One UI 3.1? The version of the One UI 4.1 Im using is on Binary 4 and the One UI 3.1 version Im trying to downgrade to is Binary 4 too.
@geotiktoka: Sadly it isn't possible to revert to a previous Android version on an official capacity. By being on Android 12 you can be sure that your device is compatible with the latest apps and features, so it is recommended that you keep up to date with the latest software.
Thanks, but my friend has Galaxy A52 too with the same exact configuration(4/128) and he didn't update to Android 12 and when I compare, his phone is faster and smoother than my phone.
