[Redmi Note 9S / Note 9 Pro (Indian Model) Question] gerega:
The update from MIUI 11.0.9 to 11.0.10 has changed some pre-installed apps. I have uninstalled more apps now including their unnecessary settings.

Please pay attention: This time I have not uninstalled com.miui.gallery, as somebody warned me that it leads to a bootloop. But I havent experienced it in 11.0.9. In this version 11.0.10 I am more cautious and I let the gallery app untouched. Nevermind, I dont neet the MI Gallery, because I prefer the open source Simple Mobile Tools from Fdroid or PlayStore: www.simplemobiletools.com I recommend the open source Lawnchair2 from PlayStore as alternative launcher. There you can hide MI Gallery app.

My device has no root, no custom ROM, just the original MIUI global. The Xiaomi App-Updater works. So I suppose OTA to MIUI12 will work too!

The debloating leaves you with a very clean phone at least you have only a handful apps installed on your MIUI homescreen. A good start!

My "old" list for MIUI 11.0.9. is here.

I also recommend: Xiaomi ADB/Fastboot Tools by Szaki, a simple tool for managing Xiaomi devices on desktop using ADB and Fastboot. There you find many of the debloated apps, that I have noted in my debloating list, although my list digs deeper in some areas.

If you are interest in the meaning of an app, simply search for it in a search engine of your choice e.g. startpage, duckduckgo, qwant etc.
