Hello XDA developer's,

I own a ONE plus ONE from amazon india and facing issue with the default features of my device .
few days back i was watching a link through my default android player , in between the video got stuck about in a min,
followed by that my device rebooted auto , and once i decided not to watch the video from android default player i had got a new issue with my contacts all of my contact saved in internal storage removed luckily it is there for import in internal memory .
So i tried to import the contacts all together selecting import all .
But it seems the Contact stopped working for multiple import it support for like 10 or 15 contact , more than that it always stop working ..
Please help me out me with this as it freaking pain to import contact individually .

Thanks ,
Ravi yadu
