Ok. Dunno how this can be useful though.
First: Stock Camera on Thumb2 (with FCam Installed)


Second: Stock Camera on Thumb2 (FCam uninstalled, phone restarted)


Third: Stock Camera on PR1.3 (no FCam installed)


Fourth: Stock Camera on Thumb2 (no FCam installed)


Question: How do I know camera ui version? (Didn't notice change in UI after flashing --> thumb2, was just busy pressing the shutter button EDIT: just read thread title, so I'm on camera-ui2 when I installed thumb)
