It’s not officially supported, but I can see a few “unofficial” community builds. I like the idea of getting a small phone as a media player. I have some experience with installing operating systems, but never a phone. How difficult is it? Is this a good idea?
I am typing this on a Samsung Galaxy Tab with the latest LineageOS. I have flashed 6 or so Android devices by now, have never bricked one. I did have to reinstall the factory firmware on one after discovering that it did *not" support VoLTE, so it was good for everything except being a phone.
That said, it is quite possible to brick your device. If you are reasonably comfortable with CLI commands (I used Linux for all, no idea if its even possible on Windows), can follow instructions, and observe small anomalies, you should be fine. The problems usually start when one step of the procedure doesn’t quite match what it says…
Also, you are probably going to forego the Google App Store. There are several FOSS app installers, F-Droid is one.
Lineage is great. I have had zero stability problems. With the officially supported devices, you get regular updates, the update process is simple and reliable. YMMV with the unofficial build.
