My phone wouldn't install an app the other day (jefitt) so I tried looking at the internal memory (% usage for Audio, etc.) and it wouldn't calculate it (just showed the calculating status for 4 or 5 minutes then that detail went away, replaced by just "Internal Storage).
I deleted a bunch of files and then tried again and JeFitt installed. Internal memory was low (about 200 MB of 8 GB free) so I thought maybe it was a bit constipated.
Now it's doing the same thing. Tried installing a couple of different apps with the above symptoms.
What I've tried:
- Deleted files so that I have 1.2 GB free on internal memory, 2+ GB free on SD card.
- Booted into Safe Mode with the same symptoms
- Simple Restart and Soft Reset with same symptoms.
This is a Motorola Razr M (Micro) with Android 4.2
