Xiaomi Redmi Note 9 Pro Max


Did the maintainer say that feature ‘works’ but you know from doing it that it really doesn’t?

Start by searching the device issue , if you found it, hopefully the porter is on it. 'Subscribe' to the issue in case it get solved.

Couldn't find it?

Uh-oh… Well it is time to let the porter and everyone else know about the fail and send the tech magic back to the workshop for a makeover.

1. Read 'Bug Reporting' section in UBports docs on 'How to report a bug'.

2. Then (this time), head to the device repository and submit it, so the porter knows about it.
