THIS! Got my XA2 somewhere in October. now is June. And it is still running And.... and I still keep my JollaC as still working perfectly (with Dalvik). Only reason to upgrade was camera but no, not yet after more than half a year not reliable. So maybe I better would have kept my money as I did with not buying the X. And that HW is still not working 100% (after how long?). [end of rant]
