Report an Issue for
Xiaomi Redmi 4X
Did the maintainer say that feature ‘works’ but you know from doing it that
it really doesn’t?
Start by searching the bug 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 GitHub Issues and submit it, so the porter knows about it.
