Hey, it’s not that easy to brick phones with Qualcomm processors because there are many resurrection methods, so congratulations. I hope you recovered aftr losing your phone because it didn’t 😭
Hmm, I don’t have a phone with Leica lenses, so I don’t really know, but if you’re interested, I believe someone has already discussed it on the xiaomi.eu forum.
Yes, that’s one of the drawbacks. However, you can find the app package name quite easily by long-pressing the icon of the desired app on your phone, then tapping on App Info, and finally on the ℹ️ icon for additional information.
I saw that there is a way to remove system apps as you envisioned using the Canta app in combination with Shizuku app. But I’ve never personally tried this method.
