Sorry guys I don't think I can make progress with this. Somehow I think the Z1 Compact has different digitizer than Xperia Z1 and our own doesn't really support tap to wake on the hardware side. So since I don't have a Xperia Z1 I won't be able to support development on this. I tried porting CTS kernel and doomkernel to Xperia Z1 Compact with tap to wake enabled and it won't work. The same issue I encountered last year when I attempted to bring tap to wake before Doomlord and mohammadAG made it. Touch isn't really detected when screen is off.
