Galaxy S3 LTE Excellent.
Does exactly what I needed. And for free!
Settings work again back to 5
Great but with limitations Amazon cloud sync does not work. (but maybe is due to recent changes in Amazon cloud storage). Also there are too many limitations in lite version (no instant sync, number of folder pairs is limited, etc). I recommend to limit only by one of the two - features or volume, not both. Better limit by volume in lite version.
Almost perfect. A couple minor bugs. Works quietly in background very well--automatically backing up my photos when charging. Backing out of sync status screen returns you to the same screen about 5 times in a row, but overall this is great. Considering full version soon, even though this does everything I need!
