Do you use a device with open source Android firmware? What device, which distro and what do you do with it?
I have a Samsung tablet with LineageOS and apps from F-Droid. Other than displaying dire warnings about the unlocked bootloader every time it cold boots, It's great for a "recliner system": email, Web browsing, E-book reader and MP3 player. What do you have, what do you use it for, and how well does it work for you?
Im currently using a Samsung galaxy s10+ with lineageOS, since the support ended in the beggining of this year.
Works prettty good, but with some downsides, no voLTE, one of the front facing cameras doesnt display image, was working in stock.
The heart bit sensor doesnt work either.
But this issues arent a dealbreaker, so its a nice experience overall.
