I was on CloudyG2 3.3 ROM, then moved to Power ROM as i had some signal issues. Later again I flashed G2 Stock ROM KDZ.
Still my signal issue did not get resolved so i again moved back to original CloudyG2 3.3
But now i see only 10 GB free out of 32 GB. The system files show its using almost 21 GB.
Please help to recover the space. Thanks.
