I'm using two Tencent apps. One of them likes accessing
/sdcard/tencent and the other likes
/sdcard/Tencent. Somehow the
/data/media/0/Tencent folder is empty and
/sdcard/Tencent has exactly the same contents as
/sdcard/tencent, so they worked fine for a while.
Recently I did something unrelated but eats a lot of RAM, and most of the background apps were shut down including the two mentioned above. To my surprise,
/sdcard/Tencent was no longer mapped to
/sdcard/tencent but they have reversed! I checked
/data/media/0/tencent and everything that was there is still there, but
/data/media/0/Tencent is no longer empty.
A reboot has a chance(!!) to fix the issue. Now I would like to know the cause of this strange behavior, and a possible solution.
I quickly merged
/data/media/0 and created an empty file, and to my surprise
/sdcard/Tencent is still showing up as a directory, not the file.
