De-googling standard Android

First of, do not login or activate Google Play. (Unless you need to)

Then use the link below to get apps. Most things can be gotten through F-droid.

Get apps

Install Fossify alternatives to phone, text, contacts and starter app.

Then start removing and deactivating as much Google crap as you can live with.

Some caveats:

• Disabling Google Framework Services is definitely a possibility, but:
  • Lot’s of apps use it and wont work without it.
  • Some apps have workarounds that can work.
  • So check each app before doing that.
• It seems that if Google Play Store is deactivated on the main profile, it wont work on other profiles.
  • Installs will be stuck in “Waiting” for ever.

Android ADB

Firstly enable USB debugging on the phone.

1. Go into About phone
2. Go into Software information.
3. Click multiple times on Build-number.
4. It will ask for pin or other authentication.
5. The message Developer mode has been enabled should show up.
6. Go back to the main settings menu.
7. At the bottom, below About phone, go into Developer options.
8. Scroll down and enable USB debugging.

Connect with usb cable to computer with ADB installed, and run:

adb devices
