Tried the Wireless USB Flash Drive with an android phone

Hello all first of all

I have the wireless USB flash drive and i tried to configure the password to wpa2 from my android phone and after i pressed save the password the phone crashed.  An error appeared “error 0” , i tried it again with the same phone and the second time it only freezed but the password never was saved.

So i tried it at an other android phone and there it worked fine so my actual question is this:

its my phones fault that it cant save the password or the flash drive has issues?
