Hello,

first, excuse about my fool english.

I developing a game which using gps module.

I used Unity 5.3.4f1 before, but I upgraded it to 5.5.0 now. furthemore, many resources and sources are updated according to 5.5.0 version already.

it worked very well on 5.3.4 version, but it is not work on 5.5.0 version.

so I figured out what is problem, it is "Input.location.Start()" !

the exception is always occured and the application is turned off automatically.(On Android phone) I couldn't figure out about solution from the internet.

anyone have met like this problem before like me? is this problem occured only for me?
