are manufacturer's own emulators good for spotting device problems?
I can see from this forum that people run into problems with LWUIT sometimes not working quite right (or even crashing) on certain mobile devices.
Can anyone advise if manufacturer's own devices (e.g. Motorola's own wireless device emulator) are any good at spotting, or trying to debug, these problems? My intuitive gut feeling is that they wouldn't be useful for that.
I ask because I don't have acces to a large amount of devices, so anything which would give me a hint that a certain device or make would have problems would give me hints on where to focus testing/debugging, etc.
