Selecting Back a screen, crashes app

Please can someone help me

When running a SC8 app on a mobile device (at this point only tested Android), if you try to go back using the back a screen option on the phone the app crashes.
I have put in a “Back” button in the app whicch works fine, but some of our users prefer to use the back a screen on the device.

How do prevent this from happening?

Thanks

Not sure. Afaik this is a browser issue. It wants to resend data which is not allowed.

I agree.

Is it fair to say that essentially the application is exiting, if so in the application / Navigation -> Exit URL, put the url you want the user to go to.
or
Is there a way to DISABLE the Back button, since I think the funtionality on the phone is the same as the back button in a browser (http://www.encodedna.com/2014/07/restrict-or-disable-browser-back-button-using-javascript.htm)
