The current update has been running very smoothly for me since 25 April (apparently an early rollout?). No crashes, no problems, no overheating battery (my battery last for nearly 1.5 days as of late, love it), stable camera… I just hope that the gallery will continue to be developed. What bothers me personally in the experience is that you need Google Photos to edit the photos. But I don’t see that as a criticism.
I had to replace the factory-fitted screen protector with armoured glass after a week because it really was a disaster (or rather just a thin film). I wouldn’t recommend leaving this film on now, tbh.
I’m looking forward to 3.1 … or 3.2, which is probably already available on the CMF Phone 2 (?), provided the keynote wasn’t a lie.
