Re: @ Anomalous Cowshed "The number of times my smartphone has crashed............."
I'm surprised by Andrew O's crashing story. Not that this reveiw phone crashed, but that he's never had a crash on anything else.
My iPhone 5 has crashed quite a few times. Enough that I now turn it off in long meetings, rather than put it on silent, so I know it's getting a regular reboot. And I've had a lot less crashing since then. It does have a few apps on, but not that many, as it's my work phone. All games are on my iPad 3.
Speaking of which I've had quite a few crashes on that too. But it gets a hammering with games and using iPlayer radio via my stereo, while I'm looking at websites, or using apps. In both cases the main problem seems to be the system not responding to the touchscreen (often the home button still works), and a reboot fixes it. I think it was only on the iPad 1 that I had a full crash, where even holding down the power button couldn't force a reboot - and I had to look online how to do a full reset which I think was home+power+volume up.
My experience of Android is probably now too out of date. My HTC Wildfire (Android 2.2.x used to crash a bit more than the iOS devices. The only solution to a couple was to remove the battery, which fortunately was possible. Including crashing a couple of times on an incoming call - and the screen just went white. But that was years ago, so I assume 'Droids have improved since, especially the ability to reset, as there's so many sealed batteries nowadays.
I don't remember my old Lumia 720 (WinPho 7.5) ever crashing. But I'd be surprised if it didn't at least once.
