On previous I preferred single take now you can't change the timing on it I think that need to be an option for further updates and sort these bug and slow responses on apps

Have updated post #1 to place a link in, "TOP TIP", on how to wipe the phone's Cache Partition and use Galaxy App Booster as this is considered best practice after a major update and can solve a lot of issues including lagging and apps foreclosing  without having to do a Factory Reset and wiping your device.

At long last, (8 days), the last U.K. carrier branded phone update is now rolling out.

Three network users on their carrier branded devices for CSC code H3G are receiving the Android 12, One UI 4 update, BUK8.

hello App booster is not available in Latin America right?

Really? It should come pre-installed with the Android 12 update.
