Where do I report an issue with the OS?
I've been getting a popup message on my Pixel 4 XL on version 13 (TP1A.221005.002.B2), saying; "problem detecting battery meter" and the battery icon has a question mark.
I don't even know if it's a software issue but my phone is in pristine condition.
@mateowoetam You have a hardware issue with your battery. It's not an OS issue. It could mean that the battery hardware or the connection to it is failing. It could also mean that it's a non-official battery that's not working correctly. There's nothing to do about this in the OS.
Pixel 4 XL is end-of-life and we provide post-EOL support for it via our extended support releases. It's not going to be supported for much longer unless we receive substantial help porting it to Android 14.
