Updated to NOS 3.0 on NP2, no data loss

I did quite some reading before updating to 3.0 as there were chances of data loss, but for those of yaull concerned about this, data loss doesn't happen in 99% of the cases.

Overall impression: phone is now snappier, fingerprint reader is faster, display looks crisper. Fonts have been majorly replaced, and we finally have the display brightness slider.

Overall I think a pretty neat job, but this doesn't feel like a leap from Android 14 to 15, feels like nothing OS 2.7.

But that doesn't mean it bad.
