I'm running v11.2.1, everything seems to be running great so far but the gallery freezes every time i open it. I did a clean install.
By the way very nice work on your roms, they have been nothing but smooth running for me
Did you change the gallery and camera at all? Try clearing cache and data for gallery then fixing permissions in recovery. If that doesn't work then try flashing the Tmo gallery and camera found in the OP.
