I noted a strange issue on my Xiaomi Redmi 9 with Android 11 (i don’t know if the problem is also on Android 10). So, the problem is: when i download a file, if i move it from Download folder to another folder in the internal storage using a file manager different from the Xiaomi one, the file is missing some hours later.

To replicate the issue:

1. Dowload a file from Google Drive
2. Create the folder TEST on internal storage
3. Open Fx File Explorer, open Download folder in the internal storage select and CUT the downloaded file, paste it in the folder TEST in the internal storage
4. After a day, if you open the folder TEST, the file is missing

[NOTE: for testing the removal, if you don’t want to wait a day, follow these steps: open the Xiaomi Download app, go to downloaded tab, clic on the downloaded file (the file was not found because we moved it), clic on Delete, after that the file will be deleted from TEST folder not from the Download folder where is not]

The workarounds are:

• Move downloaded files to a folder on the SD card instead of a folder in the internal storage;
• Use Xiaomi File Manager to move the files from Download folder;
• Instead of cutting downloaded files copy downloaded files in a folder on the internal storage and than delete it from Download folder.

Sometimes on VoLTE operator, the VoLTE is not working.

I had this problem on Xiaomi Redmi 9 with indonesian ROM (installed for MIUI native call and message apps instead of google ones).

You can solve this problem adding another APN named IMS. This APN must be added only and not selected as active.

So if VoLTE is not working follow these steps:

• Call: *#*#86583#*#* (enables VoLTE flag in configuration)
• Add this APN without selecting it:
  • Nome: IMS
  • APN: ims
  • APN type: ims,ia
  • APN protocol: the same of the active APN
  • APN roaming protocol: the same of the active APN
  • change only these parameters, leave the other params unchanged.

NOTE: perhaps this problem is due to the fact that this APN in the EU ROM is already present, but is hidden.
