Hi iStasis,
my phone's now vibrating from 0-15% like every 0.5% it charges
--> We would suggest you try with a different cable and charger, and check if this problem is still appearing.
The old Smart / AI icon has now gone even though the option is turned on.
--> We would suggest you check if your battery level is above 80%.
The AI charging notification appears after the battery level is above 80%.
If the notification still does not appear, please tell us your battery level.
In the top left corner the phone is now no longer display my carrier icon like 3 or EE and will only display this on a swipe down which seems like a bug to me.
--> We have checked previous versions, it seems like the carrier icon appeared only in swipe down and lock screen, same as the current version.
If it is appearing in swipe down and lock screen in your current version, it would be an expected result.
For the Rooted option when posting threads, we have modified it. Thank you for your suggestion. 🙂
