The AOD is not changing its position when device goes to sleep, if the AOD doesn’t do that shifting of position it may cause screen burn and as in attached pic the battery status widget earlier used to show the ear buds icon and charge status but now it showing bluetooth Icon as I already connected my cmf buds! Anyone having this issue after the latest update today and who found the solution? Help

Hello, I’m still using NothingOS 3.2. I got the OS 4.0 update just like everyone else but didn’t update because I really wanted some honest reviews about the OS especially battery life and overall performance. Anyone feel free to share their feedback please.

Saddyskib Keep your phone safe. Don’t update yet. The new version is a collection of problems, poor communication, and a touch of pretending everything is okay.

After updating this update i was always getting 5g+ but now it showing 5g.

Is this for only me or what plz say

The internet speed indicator in the status bar is cut off after the latest update on my Nothing Phone 2a.

Turning it off and on again fixes it for less than five seconds, then the bug comes back. As shown in the screenshot, the kb/s or mb/s text is only half visible. Restarting the device also does not fix the issue.

Also, please add an option to show only the battery percentage and completely hide the battery icon. It would also be good to have an option to change the boldness of the battery percentage shown inside the battery icon.

Built number: Pacman-B4.0-251230-2052-IND

I can’t send anything using the feedback tool because the category option isn’t working. It only shows a blank page when I tap it, and I can’t submit the feedback without selecting a category.

Daniel feedback page is not working in nothing phone 2a, i have mailed them and shared the log too but they said they will contact if any information needed
