Issues with external storage on Android Pie 9.0 / 10
- Model Name: ASUS ZenFone Max Pro (M1) X00TD 6GB RAM

- Rooted or not: Not rooted
- Frequency of Occurrence: All time
- APP Name & APP Version (If your issue relates to the app): ROM issue
With updates to AOSP( Android pie / 10 ), external storage gets new mount point as mnt/media_rw. "android.googlesource.com/platform/frameworks/base/+/71938e18ca4ad77519da70565710ef37e79443f8" (include http).
This change is reflected in ASUS stock ROM WW_Phone- 16.2017.2007.084 and also observed previously on ASUS pie ROM updates. So that any media files (Photos / Videos /Music ) copied to phone through MTP gets the mount point as mnt/media_rw. That mount point is not accessed even by system app like Media scanner. For example if songs are copied to external card, media scanner will scan newly added files but music player wont play that songs unless the device is restarted. This happens for video files as well.

I hope this post brings notice to ASUS Software Team and fix this problem in future updates.😊
