Since a few days, my phone has been acting up. I have a Lumia 820 with 8.1 Denim, no insider, no preview installed, standard factory version.
It all started (at least that was when I noticed) with a VLC update.
The phone had a stable wifi connection and I tried to update the app, but it stayed in the queue. There were times the app started updating, but couldn't finish it, stopped at ~50% and didn't continue.
Ever since then I couldn't get VLC to update itself.
Furthermore, it seems, I even have problems with installing new apps (it's set to install apps on the SD card). They behave the same way VLC does - remain in the queue without making any progress.
The final twist is that despite all this, I do get some apps to update themselves in the background. Last time Atmosphere managed to pull it off.
I have no clue what this issue is and what might cause it nor do I know how to fix it.
Any suggestions?
