I’ve been using the beta through the weekend feels very stable and complete, battery life is comparible/on par to 2.6 .
The phone is snappy and responsive.
When there is some overlay on the screen. (like chat bubble or the floaty window) I’m expiriencing weird screen flickering and full screen discolorations and laggy animations. I expirienced something like this around version 2.0 and rarely later.
One tiny issue was that I had to reset some of the widgets after the update but that’s so minor I think we can forget about that.
Apart from that this is a great release.
