Where is the orientation sensor?

History

Can someone tell me which part of the iPhone 3G contains the orientation sensor? Is it the power button/headphones/volume switch ribbons?

The iPhone I have here won't rotate and I don't believe iPhone 3G has the rotation lock capability.

Tam BM, you are right with not having a rotation lock. Anyhow, the attached images shows you the location of the LIS331DL accelerometer which is responsible for the portrait/landscape rotation. I would try to restore my firmware and see if that will make a difference in regards to the rotation. Hope this helps to get you started. Good Luck

Ahh so the actual logic board is responsible for this and there is no way to simply replace an inexpensive part to fix the problem? Ok I will try a restore but I am not hopeful. Thanks for your responses everyone :)

Tam BM,

Yes, it is part of the logic board. I can imagine it is frustrating....hope you got some luck.

Wow, I did not know that it was the proximity sensor that was responsible for the rotation of the iPhone display. Are you sure about that? Here I thought the whole time, is was the 3-axis accelerometer that would cause that.
