So I just updates to Onw UI 7 and really wish I hadn't. Here is a list of things that stopped working:

1. Clicking the settings button does nothing, not even if I use search to find it. I cannot open Settings anymore.

2. The Edge panel disappeared even though it's enables.

3. The top notification and settings is gone. Swiping down does nothing so I don't have a quick way to turn on wifi, location settings, bluetooth  ... anything I use constantly.

4. My phone is set to vibrate and it doesn't vibrate when messagea come in even though the vibration works.

5. My bottom buttons are set to apps - home - back and yet the back button sits on the left and clicking right or center does nothing.

The whole top bar of my keyboard is greyed out aside from the settings wheel so I can'r use emojis, for example.

6. No easy way to switch between apps unless I fully exit them as the apps button doesn't work.

7. The clock disappeared from my top icons.

I'm sure there's more. Already lost an hour on this. So regret having updated.
