I just found out it seems this app may not work on my Tab 2.
I've installed it on my Samsung Galaxy Tab 2 7.0, with ICS installed. It will not let me snap any pictures and the touch focus box [the 4 small brackets] or whatever it is called is a reddish color.
If anyone else use this on a tablet are you having this issue?
I installed Camera ICS and giving it a try. It seems to take the pictures. I did email the developers about it.
