My Galaxy S II started to act weirdly recently - application can't be installed or updated neither in Google Play, nor locally, the Settings > Apps (Storage) says "Computing" forever, my SD card fails to dismount etc. But other than that, the phone operates normally - all files are accessible, all apps work etc.
As I needed the updates and installs to work, I needed to fix this. It appeared that when I physically take the SD card out, all is suddenly fine. When I put the card back in, I can access the data on it, the files are visible over MTP on my Windows machine etc. but the above mentioned problems are back again.
I've checked the card itself and it seems to be fine - it operates normally under Windows, the Windows check tool didn't find any corrupted sectors or anything like that. So I guess the fault is either in my phone or in Android - does this sound familiar to someone here? Is there anything I can do to try to fix this?
