I have to continually reload the software on my SM-J110F. I have reloaded it 3 times myself using KIES/Smart Switch, which always installs the "official" VODACOM XFA version. And a Somali cell repair chap installed a UAE version, which has now also failed. Do you have a proper fix? I suspect this is a bug from VODACOM bloat ware installed, because you only see this in SA and not in India, where this phone is also sold. I am happy to pay for a solution.
