4 stars instead of 3 as the developer is not making or attempting to make money and it works very well  a few minor issues  my phone records sound in stereo and I've noticed that often only 1 of the sound channels has been recorded whilst using video. Monophonic phone users won't be affected by this  but those of us who purchased stereophonic phones for realistic all round sound may not be happy. Small sensor in phone so it's not a dslr or apsC type sensor so don't expect drastic improvements and you'll be happy. Can make your photo taking experience better than your stock camera app if used correctly and you understand how to use the features
