We have a lot of available Launchers that can be downloaded in the Play Store, but me myself, I'm still sticked with using the One UI Home launcher. Here are my tips to optimise the launcher:
On Recent tasks interface:
• Turn off app suggestion
• Go to settings > search "Usage Data Access" > Turn off data usage access for One UI
• Go to settings > Accessibility > Visibility Enhancement > Reduce transparency and blur
This optimisation is particularly useful to those who are using entry-level and midrange level Galaxy devices.
Hope that helps !
lots of background apps running perhaps. consider to put apps in "deep sleeping" mode except for the apps that u need to receive notification on time
