Tried this over the weekend. Good and bad.
Good, it updated my phone from 13 (maybe 13.1.1, not sure, it had gotten a few versions behind) to 14.0.1 without any direct data loss and it does seem snappier and new security updates are always nice.
Mixed (bad, then better) is that it wasn’t able to mount my internally-formatted sdcard after the update. Rebooted three or four times and it was never able to mount. Finally booted with it unplugged, forgot the sdcard, shut down, reinserted, and then reformatted as internal again, while losing all its prior contents. The better news is that unlike with Android 12 and 13, the reformatted sdcard has consistently mounted on all the reboots since.
Bad (for me personally) is that the Teracube Android 14 had issues with rooting. As soon as I unlock the phone screen after booting up with a rooted boot.img, it crashes and reboots. Eventually I’ll care enough to get a logcat, but for now it just means I can’t plan on using the phone at night courtesy of CF.lumen anymore.

Besides that, I’ve managed to get an angry “why did you lock me up trying to do too much” reboot several times but that’s not new and all in all, it’s seemed to update and behave itself for the most part.

After a successful update/install from 13.1.1, the first attempt to open the Teracube app failed. Seems to not be updateable in the play store. After killing it and clearing data, seems to open fine again and now I can post my results here.

1 week since I updated from 13.1.1.
Nice to find NFC payment working, on Google wallet, only change I saw was the background image.
One thing that showed up but after few days went away is the Android control buttons/icons were overlaping those of Chrome (i.e.: when showing the controls for a tabs group), but as I mentioned the issue is no longer present.
The only caveat for now is that when I go into a low coverage area, It doesn’t automatically reconnect the mobile data: I haver to turn the airplane mode on and off for it to work again, acting on the mobile data switch doesn’t do the trick.
Besides that, which is not really annoying for me (as long as it’s not present in the final release :stuck_out_tongue: ), I’m quite happy with this beta quality. Congrats !

I downloaded the installed the update. It installed fairly quickly on a phone running not quite the latest Android 13. The phone was recently reset so there wasn’t much to carry over, but it does appear to have carried everything forward.

Disabling animations under Settings->Accessibility->Color and motion makes the phone a little less sluggish and responsive.

I hate Android’s animation speed. Way too slow. If you want to still hide loading/switching delays but not over-wait, try the 0.5x length option. That feels like a nice compromise on my device, and I even use it on my wife’s Pixel.

Installed this update a few days ago.

The first boot after updating got stuck on the spinning cube: after a couple hours, I put it into recovery mode (which worked, at least) and ended up doing a factory reset. (Wiping cache didn’t help.)

Every time I reboot, it forgets my app battery-optimisation settings and my default-app (browser, SMS) settings.
