[GUIDE] [NO-ROOT] Complete Samsung OneUI Optimization

[Hamid Chikh]

##### LAST EDITED: 23-01-2021 ##### URGENT UPDATE
- DELETED Spyware (com.sec.android.systemupdate).
This app affects SECURITY, PERFORMANCE and BATTERY LIFE.

Keep in mind that i test apps/presets for at least 3 days before updating the thread.
This app caused performance hit for me, i noticed dropped frames for about 3 minutes after the boot sequence, and battery drain. I can't quit remember if it was included in the firmware or got loaded with time thru some ads.
Don't worry about system updates, the process that's actually responsible for it is untouched.

Here are some articles:
Techcrunch
Sammobile
Zimperium

We're now at:
- 251 Deleted apps
- 2 Disabled apps (uninstalling these will break apps.)
- 160 Kept system apps

ONCE DONE, REBOOT INTO RECOVERY THEN CLEAR CACHE PARTITION AND REPAIR APPS.

Hi. WIfi calling is enabled on my S21 but calls just abort after 1 second. Are there any other services responsible for flawless WIFI Calling?

I'll let the other users reply, I don't use wifi calling

 

[docson]

Sh*t. Has definitely to do with disabled/uninstalled services. Just restored everything and Wifi Calling works again. Any help appreciated as to what service to keep.

With all respect but dude. Check this app manifest. Look at the permissions and launch intent event. You have removed all of system apps. I'm sure your logcat is full of exceptions and errors. I believe your gain are from capping frame rate, using batter saver and disabling location from some app or disabling sync. I have debloated my device but without removing some nice smart stuff that this device provides

Also please leave IMS stuff intact. If someone doesnt want VoLTE/VoWifi or RCS just disable them from the device.
When in countries they are going to disable 2G/3G and the VoLTE will the choice to go for voice, how this device is going to work ?

Also why do you keep ARzone ? Which functionality breaks ? Also samsung keyboard is necessary for the cilpboard app edge to work. Just to know

Hi, do you have kind of thread with proper presets. Can you kindly share Us too. so user will pick which they prefer. I also sometimes want to retain the special/system apps on phone. Thank you!

Maybe you guys can share idea each other. So other feature on phone will not lose.

Do you have a key to why Wi-Fi call drops after these presets?

About the 3 facebook backogroud apps that come preisntalled. Are they "spyware" ? App Manager & installer are about updating the background apps. So resource wise they are OK.
About the Facebook services app, i am experimenting. Without it many times i lose notifications. With it i think don't lose them, without noticing serious battery drain or lag. If you dont use facebok katana or orca then you are free to uninstall/disable them

Hi !
Please, feel free to use my suggested personal presets, or not.
If you don't like my personal choice of apps, feel free to skip this thread.

Of course. This is what i do . But please don't spread false info for example for spyware. We are all here to share info about making our devices useful/ better or more well-suited for our needs.

Does anybody have idea which thing is responsible for the split window function? Doesn't seem to work anymore. I could attach a log of what I disabled (nothing uninstalled) if needed.

Can you enable these , I am not sure which one is really responsible as enabling all of these solved my wifi call problem.
