@Louis - enable it and you tell us your findings :)

Edz ( 2017-10-12 14:07:12 +0300 )edit

slight correction: first mcetool command should be "mcetool --set-doubletap-mode=show-unlock-screen"

Ahhh thanks, worked like a charme.

I have to say, battery live seems to be worse then with the Android ROM from Sony already. But will have an eye if it's getting even worse.

Works! Great! Thank you!

I'm not sure if this is related to tap-to-wake/unlock, but I sometimes experience the issue on my Xperia X with enabled tap-to-wake that my screen is completely unresponsive after wake up. It won't recognize any touch, I have to turn it of and then on again to be able to use it. Does anyone have similar issues?

I wonder how much worse is the battery life after enabling it?

I think, however I have liked double-tap with N9 and Jolla 1&C, I will pass this in the beginging sofar. I have so bad memories with the high power consumption of Jolla C. However, I do miss double-tapping. In fact I am trying to that with Sony Sailfish X all the time until I note that it have not any influnce ...

N9Sailfish ( 2017-10-15 19:31:37 +0300 )edit

I tested consumption during the night(8hours). There is no difference for Jolla_C, but for Xperia_X... Consumed power WITHOUT doubletap is 31.25mW(2...3% during the night) and WITH doubletap is 63.75mW(6...7% during the night). 3G=on, Wi-Fi=BT=Internet=off.

Oleg ( 2017-10-16 10:34:40 +0300 )edit

Thank you. This confirms that I will pass sofar.

N9Sailfish ( 2017-10-16 17:07:03 +0300 )edit

I wonder if there will be an 'official' support for this with no or very little effect on battery life, at some point.

Ingvix ( 2017-10-19 09:51:22 +0300 )edit

For me this has had extremely little effect on battery life. Something like 1 to 2 percent in 12 hours.

In Sailfish X Build and Flash wiki, this command is given:

Double-tap to wake is deactivated. Activate it and help testing in various scenarios by:

mcetool --set-doubletap-wakeup=proximity

I used that one and at least so far the battery consumption looks still very good (phone was charged to 100%, unplugged and now after about 1-1,5 hours it's still at 100%).

How does the commands presented in this thread differ over the one quoted above?

Thanks @evo3de. But unfortunately it doesn´t work properly if I have enabled low power mode.

During the 5 seconds the clock is shown in lpm mode, double tap does nothing.

If you would like to use low power mode and double tap simultaneously you have to set

mcetool -M show-unlock-screen
mcetool -z proximity
mcetool -i enabled
mcetool -E enabled

Have you faced an unresponsive lockscreen with these settings? At the time when opened with power button the lock screen does to response to any touch gestures. I need to press the button again to turn the screen off and back on to get it working. EDIT: Never mind. I think it's one of patches that's doing it.

Does this actually enable the double-tap wake-up gesture which I badly miss on my Xperia X?

Edit: I just found out that this indeed enables the missing gesture! Thank you much guys, now my Xperia X is perfect!!

yes, and if you use this command:

mcetool -M unlock will pass the unlock screen and go direct to the home view.

poddl ( 2017-10-13 00:52:51 +0300 )edit

Yes it does based in my testing. how do you undo the command above?

XFish ( 2017-10-13 17:22:55 +0300 )edit

I think that command mcetool --set-doubletap-mode=show-unlock-screen disable that -M unlock option (quick tested)
