Hello,
I'm TA. I waited for UT to come out. Then when it did it only worked on a few phones. Now that there are some affordable choices I do see a Linux phone in my future. I just so happen to have a ZTE R2. So I think I'm looking at this https://github.com/thojohns/android_kernel_zte_z5151 .
Not sure what I can do here. But I'm willing and eager to do what I can.
