i developed a home screen widget. the first release was tested on a nexus one, htc evo 4g and motorola droid. worked fine. after release in the android market, someone reported that it didn't work on a samsung fascinate (galaxy s). it turns out there are 2 incompatibilities (bugs?) with the galaxy android implementation. one is with layout and the other with intent handling.
they're easy enough to work around, but where should something like this be reported?
I would start by posting questions here on StackOverflow, describing your actual symptoms (one question per theorized bug, please), so we can hash out if indeed there is a compatibility issue. Or perhaps your problems have already been addressed here in other questions.
Once we have determined that there appears to be genuine flaw in a device, depending on the manufacturer, I can perhaps alert them about the problem. While there are few public channels for this sort of thing, I try to establish relationships with as many device manufacturers as possible, just for these kinds of issues.
Also, once the compatibility flaw is confirmed, I, you, or somebody can file a bug against the Compatibility Test Suite (CTS). This is a battery of tests that a device must pass to qualify for the Android Market and related apps from Google. Genuine compatibility problems should be picked up by the CTS, so we do not run into similar compatibility issues in the future. For example, here is a CTS bug I reported related to a flaw Samsung phones, and here is a CTS bug I reported related to a flaw in HTC phones.
It is fairly important that I see compatibility-related StackOverflow questions. Since I don't know if the @ syntax works in questions, you may wish to append a comment to your own question, addressed to @CommonsWare, to increase the odds that I'll find your question.
In general, bugs with particular Android phones should be reported to the manufacturer. Unfortunately, you often need to do a bit of digging to come up with a place to contact the manufacturer. For Samsung, you could try just filing a support request? I couldn't find any Android specific bug list.
