I recently upgraded to Kitkat 4.4 Cyanogenmod 11 from stock 4.1.2 touchwiz rom and im now missing a lot of storage as you can see i only have 863mb of storage left and ive used like an 1/8th of 11.35GB on the phone any clue as to why this is and how i can fix it?
Ive tried booting into recovery (CWM 6.0.4.4) and factory restting device, wiping cache and dalvik cache but no luck if anybody has any ideas i would be greatful! thanks
