Redmi Note 9/S/Pro

[Discussion] PTP doesn't show pictures saved on SD Card ?

Hello,

I have a Redmi Note 9S (curtana)

My phone is setup to save pictures on my MicroSD card

Now, I want to download them to my PC, and when I choose PTP protocol, it shows almost no pictures. In fact it shows only those stored on the internal storage, and not those that are stored on the SD card (almost all pictures).

How to fix this please ? Could you update your apps for that ? Is it possible to select which folders are used for PTP protocol


BTW, I don't want to use MTP because there are way too many other pictures that get downloaded (whatsapp folder for example, thumbnails...)

Thank you

By looking at android's source code I found this:

Starting from Android 4.0.4 :
- // We restrict PTP to these subdirectories (DCIM & Pictures) [1]
- // In PTP mode we support only primary storage [2]

This still seems to be the case with Android 10 [3] [4]
Starting from android 11 it is located here [5] [6]

May you (xiaomi) update the firmwares so that it does also take the DCIM & Pictures folders of external storage ? How to reach developers to ask for that change in a future update ?
