[Xiaomi Poco F2 Pro (Redmi K30 Pro) Questions & Ans] pppppp:
I am late to the party. This is my list of disabled packages. I appended descriptions when I could provide them. And I have the full adb shell command because I use the list often. The IR remote app is not there because I use it :p

This list is not exhaustive, but at least I found some descriptions
