I have tested the normal files responsible for "tap to unlock" extracted from the firmware you supplied and used them on another CFW and the rotating does not work.
So there must be another file which is necessary which now controls the "lock screens" rotation in C6v40
I have checked all other known file related to "tab" and "swipe" already. The only file has difference ins the popup clock.exe. Even you combined the telgesturecontrols.mif of swipe unlock to with tap to unlock, nothing will change. It'll only change the tap color. I tried everything and found about popup clock.exe.
I replaced the popup clock of swipe, to the above CFW, and it became normal swipe unlock without the feature I said. So definitely the popup clock.exe is the one who plays the roll of orientation handling.
Someone who are smart with .exe file have to play with this.
Thank you for your valuable time buddy.
