i usually use the app on wifi.
if its running and i move out of wifi but still have 3g coverage, i find the app will not connect
This may not be a problem of the RHP app but of the phone, however other apps switch over ok, so i think its the RHP app somehow.
I have a Samsung Galaxy
I had the crash loop once last week but i can't recall the lead up.
I will take more notes if it happens again.
The most recent update fixed a lot of issues relating to phones restoring the app from the background. The issue occurred in low memory situations, possibly after playing other games or heavy web browsing.
It was a design error, but this should be addressed on this version. (I now know how to test for this problem effectively so can avoid it in future.)
So, if you are not using the current build, update ASAP, but if you are, then I am very interested in the cause of the problem.
