DF crashed on 1050 only after install, working after device restart.

I wrote a datafield for my friend request for Edge 1050. Unfortunaltly I have only Edge Explore 2, so I tested once in device. After installed the datafield it crashed, I means I got "IQlogo". But after I restart the device, the datafield start to working well and as I know it is still working. But I got review with the same "IQlogo" problem, so looks the story is not separated problem.

I have no access to any 1050 nearby, I cannot test on device and inside the emulator there is no problem. Here is the code, if any 1050 owner developer can see it and debug on device, it would be nice.
