Hello,

"Safe" meaning: No google or other per-installed Apps!
It doesn't work for every smartphone and the only thing i can provide is a little guidens while you do the actual job, but for the most part it is not as hard as it might seem. It worked for me!
So, if you are interested, contact me and i will see what i can do... --> tecmann.falce@outlook.de

But what are you actually doing? Please clarify......

If you're looking for a good security setup, I'd say fire.Onion on Android works. Its super secure but might make you look a little suspicious since it allows you to access sites that are .Onion (aka deep Web links)

I think he's just talking about the pre-installed apps on a smartphone.

>>4 Yes.

He's right, some apps like _Google Play services_ are not open source, and have access to virtually whatever is on your phone (plus internet, of course). And having this kind of apps is made compulsory to use a lot of other apps.

I guess >>1 wants to teach you how to disable all the Google and other non-privacy friendly stuff, to replace it with open source applications available on F-Droid.
That's what I did on my phone, and I recommend everyone to do so.

But, >>1, you don't really have to request emails, you can simply post the stuff on this board.
