From my time being on Android, I've come across a few errors that say they don't have enough "space" and this is usually down to SD card errors - but in this instant I'm completely stumped. To the point I think it is a very very bad virus.
Mum's phone: Note 2 - SIM unlocked, bought outright - she's been using it for over a year now
Symptom: When trying to open ANY picture (be it screenshot ON or OFF the EXT SD card - the erro (attached) crops up.
Things I've tried:
-Changing folder location of the camera app
-Clearing cache for camera, my files and gallery
-Clearing dalvik and cache in recovery
-Removing EXT SD card (with safe to remove and pulling out suddenly)
One thing I've noticed: I CANNOT move the DCIM folder. It says it "cannot be copied/deleted/moved"
The DCIM folder in "My Files" in fact doesn't exist as a folder - looks like a .DAT file - and when trying to click for details on the folder - it force closes the "my files"
One thing that's curious is that she can get the photos OFF her phone and view them on her PC without any problems.
I thus think the phone has a virus (also because there was two apps installed on there, which I've never seen before - apps that are from the play store, but apps I've never installed nor imagine my mum installing them)
My only trail of thought is:
TB up and factory reset the phone.
