ahoora_0101 hey mate. It honestly depends on your device and,
If I used the Phone (2) or (2a) I wouldn’t install the beta at this stage as stable release is coming later month.
If I used Phone (1), (2a) Plus or CMF Phone 1 I’d consider the beta if (a) I had another device I could use in case the beta was buggy (b) I wanted to experience the latest and greatest but am willing to risk the odd bug here and there.
Personally, I’ve enjoyed 3.0 on my Phone (1). Nothing push very refined updates. There’s lots of great features coming!
