When I tried 3.7 on my gta04 phone the display had a slightly greenish (or
maybe yellowish) tinge, particularly when viewed at an angle.
I at first thought it might be related to the changes in the panel
configuration (I have an out-of-tree panel driver) but making changes there
had no effect.
So I bit the bullet and did a git-bisect, and that is how I found that
problem.
