Hey guys, My r22 has been having some sd card moving problems, I move an app it wont do anything it wont move it, it says moving for ages. Not a corrupt sd card, tried a factory reset, tried heaps of different apps, tried different sd cards, tried formatting the sd card and tried waiting for it to stop saying moving. 

anyways I was searching the ZTE support page and found a r22 sd card upgrading software.
Do you think that  would help to fix the problem?
