[HELP] - Disable android system services!

[Zerinho Code]

I want to disable some service of the android system to release more ram, need help, which one I disable and which one I leave activated.
Services of which I am saying:
1- BackgroundDexOptService
2- ExternalStorageFormatte
3- FullBackupJop
4- GeofenceHardwareService
5- LocalTransportService
6- MountServiceldler
Which one can I disable?

Why don't you just go out and buy a cheap flip phone? When you disable any or all of the above your "smart phone" will cease to be smart.

Android is very good at RAM management in stock form, so it's likely not going to be worth messing with these.

I disabled only the BackgroundDexOptService and the LocalTransportService just to lighten the RAM a bit, no problem. Thanks
