My feedback so far with a Fairphone 4 with 6 GB RAM and 128 GB internal memory and an MicroSD card for additional external storage:
Update went smoothly, everything works so far.
Open Camera is able to use both back cameras by switching between them with the original Camera API as well as with Camera2 API. However with Camera2 API are 3 cameras reported: Camera ID 0, 2 and 3 where 0 and 3 are the same camera and 2 is the wide angle one. With the orignal Camera API only ID 0 and 2 are reported.
I can not test aptX right now, maybe I’ll post an about this later when I have access to a headset with aptX available.
Edit: aptX still does not work (Pioneer SE-MS7BT).
Yes, I’m a Swisscom user, too. And got that update today. It’s Android 12.
 So far: I dislike the huge ugly clock, the pill-styled huge buttons in the quick access and the position of the Google bar (which I’d love to move to another screen, bc I literally never use it) but I guess I’m gonna get used to it.
Yeah, I also installed it now and so far it seems stable. Huge performance gain on app switching!
Since, I had Android 12 on the device before my FP4, I’m already used to it and it feels good to be back again.
Just give it some time and you’ll grow to like it aswell.
Finally, this was the update I have been waiting for. I’m installing it right now. Now I can finally ditch the (sorry, Fairphone) crappy stock camera app and switch to GCam and also use AptX and have a more dimmed phone. A big thank you to the Fairphone devs for listening to user feedback!
I’ve been ignoring the Android 12 update so far to avoid the problems with the glance widget and the clock as well documented in “Android 12 has come to the FP4”, and because I tend to avoid being an early adopter anyway because of the inevitable teething problems, but it sounds like neither of those specific issues have been addressed in this update, right?
When I installed the update, I was happy because of the BT fix. And was hoping that other problems would be fixed. I know how to describe my disappointment with this update. The quality is so inferior and bad that I have the impression that the model maintenance is being done by a person who is also not able to test what has been fixed at all. Dear employees of the Fairphone Group. Your smartphone is a premium device with mid-range hardware! So please invest more energy in the software than in your marketing. Advertisements are already running on TV. Congratulations if you manage to sell more devices, if you don’t want to push your customers towards an iPhone or Samsung, then work on your software. This is not an acceptable condition.
