Is my phone's accelerometer broken?

I think the accelerometer on my phone (HSPA+ Samsung Galaxy Nexus) is broken (evidence
). Am I right?

I noticed that my phone has difficulty changing from portrait to landscape mode, especially recently. I downloaded an app to read the output from the accelerometer and noticed that it registers a constant 2Gs of acceleration in the Y axis, I think in the downward direction on the assumption that the coordinate system is right-handed (positive X is to the left, and positive Z is to the back of the phone).
What you see in that image is me putting the phone in various alignments and then shaking it vigorously. As you can see, it doesn't show any change in the Y axis. Sometimes when I check it, the Y axis graph hovers around 2G but will show small amounts of jitter when I shake it, and sometimes it hovers around 2G but goes down to one when I put the phone in an orientation where it should be zero.
So my questions are: is this likely to be a hardware problem? It's not immediately clear to me why only one axis would be failing, but I don't know how accelerometers work. My other question is how I can get it fixed. This is the international version of the phone, but I live in the US, and so the US Samsung help line has told me that they can't help me and I'll have to get in contact with the UK tech support. Will I have to mail my phone to a different country? Are there places in the US (or even, with luck, in Saint Louis, where I live?) where I can get it serviced instead? Thanks.
