If it works on the emulator I can't debug myself. I made a few checks, and it happens sometimes that the simplify command takes a few seconds on the emulator (which would mean the physical calc seems to hang). But I can not reproduce in a deterministic manner and that never happened when I did
time(simplify(Ans)). Maybe it's a GUI slowness, I don't know.
