Went from a passport, to a g4, and just got a g5 yesterday. Same sd card through all three phones, no issues.
I do feel your pain. I loved the gestures of bb OS 10.
I've had my phone for about five days. I had a blackberry passport prior, so of course I'm realizing the app gap was a bigger hindrance than I believed.
That, however, is attributed more to the Android OS.
In terms of the phone, I haven't had any complaints. I use sixty percent battery...
