SOLUTION: Phone running slow after One UI 7 update

[RevengeOneUI]

A lot of people have been posting about more battery draining and slow performance since updating their phones to One UI 7.

There is a free Samsung app that helps optimise your phone after an update, and all the time!

It's normal and expected for your phone to run slowly or drain battery quickly after an update, as the apps need to optimise themselves to the updated OS.

The Good Guardians App is downloadable for free from the Samsung app store, and within it, is the galaxy app booster module, which is perfect for optimising your phone after an update!

If you have any other questions about the update, or Samsung phones in general, I'm quite tech savvy and have looked into it quite a bit, and discovered things myself, so comment your question and I'll do my best to try and help you!

See attached images.

They clearly tell you that it's perfect for this.

All available modules within the app (on a galaxy a16)

Nice to see A phones with it. On one ui 6 it was mostly just S phones thay were able to use it

I've had it since before one UI 7. I'm not sure exactly, although I know that good lock isn't available on most A series phones.

A lot of complaining always comes around summer time. And typically the first thing people blame is an update. More often it is simply weather conditions that affects a users battery run time.

Basically useless app, can do everything in settings without it what's the point??

These are not the same features as available in settings, the optimization processes here the phone usually will do itself over a long while, but you can make your phone do it instantly.
You cannot do this from settings, see the comment from @arainwen27 for more explanation.
