Whenever I search for questions I have about Android system apps, ADB, flashing, etc. I noticed all the search results are really scammy-looking websites with instructions that sound like they were translated from Chinese by an AI.
It doesn’t make a difference if I use Google, Duckduckgo or Bing.

Also, there seems to be hardly any official documentation for Android available. Even finding out what the preinstalled system apps even do, what exactly is needed for push messages to work, or what the different permissions do is impossible for me.

I know of xdaforums.com but when I look there I usually end up in a thread with 30+ pages full of users asking questions that get no helpful answer.

How come there is so little good information on Android? Or am I looking in the wrong places?
