A few days ago I was surprised to see my "internal" sdcard space filling up, and found two files in the .thumbnails folder under /mnt/sdcard totaling 1.2 GB!
I deleted them immediately but today again there is an 800 MB file there.
I could go on deleting these files, but surely this is a major bug? A quick Google search reveals that this is not just a G300 issue. Does anyone know anything about this? Any solution?
