Moto g7 play with lineageOS 20 + microg + magisk delta I'm also running adaway and blocking all the tracker activities from my apps using app manager, and of course, using the most FOSS as possible for replacing proprietary apps. It works well, but sadly this phone won't allow me to hide root and the locked bootloader, so no safetynet because of CTS verification.

Edit: if I use hardware attestation disabler on lsposed, it passes

Pixel 7 for GrapheneOS

Fairphone 3+ with /e/OS. It has been 3 years now, still working fine, and no major problems really. It is expensive for what you get, but if it can help reducing e-waste and spare me the burden of buying a phone every 2 years, I think it's worth.

Currently a Pixel with an anonymous custom ROM, although I've got a PinePhone on my desk I need to test more.

Cell phones are incompatible with privacy. Any phone necessarily constantly sends your location to your cell provider just in order to work. But even if that's true, there's no reason to also let someone else be the remote administrator for a sensor node with a camera and microphone that you carry everywhere. Running a mobile OS with a universal backdoor is bad times.

I'm using a pixel 6a with GrapheneOs

Pixel6 with grapheneOS

I'm using a Librem 5 as my daily driver

I recently got myself a Pixel 7 Pro. the preinstalled OS really tries to push all the Google stuff on you, which isn't great.
but after a quick look around for 1 hour, I installed GrapheneOS and am very happy with it

although I'd really like to have a Linux smartphone. but there seems to be none with good hardware...

Unfortunately most of the "privacy phones" really aren't that great of a smartphone experience due to them running Linux which isn't nearly as developed for smartphone use as Android or iOS.

I personally use a Samsung Fold 4, and run Firefox w/ add ons, DDG for search and app tracking protection.

Apple likes to boast about how iOS is more privacy focused than Android, though. Grain of salt.
