Wook_sf and the thedead 1440, here is what I tried:
wook_sf, I tried everything you told me and nothing actually worked!
thedead1440, I did what you told me, I tried tracker-control -r as root and as user (as user first) and then I uninstalled the Roboto game which you claim to may be the reason, took a pic with the camera which was detected by the gallery (it was the only pic detected in the gallery) and then rebooted, left it for 3 whole hours, no detection of any photo, although Music and Videos are synced and refreshed successfully with no problems and I hope they stay that way, please find me a solution..
Thanks guys for your great work, keep it up
