Hello @fredldotme
Thank you very much for your answer !!
Sorry for the delay, I was not notified
Actually, I am a very infrequent phone user. My main point is privacy, notably avoiding tracking.
What make me hesitate is :
On UT, there are probably no tracker at all in the OS, but maybe some in the (web) apps. And there are still some when browsing the web
On DeGoogled OS, there may be links with Google Servers (but I think spoofing the identity with microG), but some systems may block a list of trackers at DNS level, and some VPN (suited to Android but not UT) can block even more trackers
Which side is the balance tipping toward ?
Thanks again
Thomas
