Since I got my M8 I have had all sort of weird issues with the ext sd card.
For example, I have the camera app save photos to the ext card, and all seems to be fine. I can view the photos immediately, delete them, edit them etc.
However, after a few days, some of them start becoming unreadable and inaccessible, some just disappear.
Another example is Spotify. I have it download music for offline availability, and all seems fine for the moment, I can play some files offline, but everytime I re-open the app, I always get some missing files that spotify has to re-download. This is a good situation, as sometimes, when I open the app, it behaves just like it is the first time I use it, and I have to sign in and re-download everything.
Also, when some apps update, they automatically move to the ext sd card. After a restart, they become unavailable. To fix this, I have to re-install the app, and immediately move the apps back to the internal sd card.
I have tried 3 different cards, all 32GB UH1.
Please note that before the M8, I had an S4 and I had no such problems.
This is really annoying. Can someone please help me out here?
Thank you in advance!
