QPair fix for incompatible device
My V500 wouldn't install the latest version of qpair, play store says its not compatible, lol. My SGS3 installs it fine but the different versions cannot connect. I saw a couple of people had this problem, so I thought I'd post my simple solution.
Titanium backup on the device with the latest version, copy files via blue tooth (or email them to yourself) and install on other device.
