The primary thing I'm seeking is to transfer app data from a lot of games from my Galaxy s2 (os 2.3.6) to my Galaxy s4 (os 4.2.2) I'm looking for something that's easiest (1-click or "plug and play" level simplicity really), and willing to pay up to $5 for a good fit there (if it costs more, I'd like to consider it anyways). Otherwise, we do it the old fashioned way with tutorials and scouring for info. I've researched some options, but would like to hear more suggestions.... 1) MyBackup Pro research: Won't work. Doesn't transfer App data. Looking at the description, I made a mistake and thought "system data" was "app data". I've already asked if the dev will grant me a refund for the premium version. Otherwise, lesson learned with your wallet 2) Helium (premium) research: probably won't work My gs2 is still on Gingerbread, and this only works on 4.x (ICS) or higher. There appears to be a desktop component that may be a way of getting around incompatibility with a 2.36 os. 3) direct transfer research: may work I don't know if that sticky thread on transferring data between an And and PC works for 2.3.6, but if I can figure out where save data for apps are and where they should go on And 4.2.2, this should be more work, but also more rewarding 4) contact Samsung to see if they have any solutions research: no info Still looking into this took Anything else? Thanks in advance!
