The back button issue is a hardware issue, as far as I can tell. It is the same on all ROMs and kernels. It even happens in recovery.
I have been doing some reading on touchscreen implementation and have reworked the touch drivers. I have put together 2 versions. Nothing has changed from 06MAY build except touch screen drivers.

BSydz_Pa-Touch3-kernel-CM9.zip
I need detailed comparisons between touch1 kernel included in 06MAY ROM, touch2 kernel, and touch3 kernel. Please only provide relevant info pertaining to the touch screen please. This is not gonna break GPS or make your favorite app fc, only one thing has changed and that is touchscreen.
I did all this from my phone, I'll clean it up when I get on a PC.
Touch 3 seems smoother than touch 1. I have not flashed touch 2 yet. I'll continue to use touch 3 today and report back with more detailed results.


if I may ask though, can anyone help me on how to get the auto-brightness to work? I have it set for auto but the screen doesn't light up that bright in the sun. Is something wrong with the default values? Thanks in advance!
