Activating the display with gesture
Answered
Activating the diplay with gesture is a nice idea, but don't work very stable.
I think it is a better idea to point a doble time on the black display to activate.
It's faster and secure driving with bike.
The same question
Good day Carsten,
if there is need for an alternative solution, feel free to try one of many available applications on Google Play: https://play.google.com/store/search?q=double%20tap%20screen&c=apps . I've not tried any of them, so I have no suggestion, but I'm sure, one of them will work as expected.

Gestures:
...doesn't work well?
Double tap display with gloves sounds not much better :)

For your information some tests.
Alternative fine solution by app "DTSO" Gesture control.

White or black gloves ?

Is proximity sensor activated ? To test the ir proximity transmit led use second phone's cam, most have some ir sensitivity. Fine to detect the proximity ir light source, should be on continuously (= consuming some power)

Carsten - this topic has been raised a few times in help.locusmap.eu. I gave up trying to get it working with Sony Z1 even though two simple diagnostics apps could detect IR sensor no problems. Pity. Beware some of these other apps chew up battery power very quickly to perform this function - test.

Power savings. On phones where proximity switch does work (most do) there is only some minimum extra power by the proximity ir led.
This is all about LCD only, not Amoled screens.
This I have noted in tests:
Double knock or any knock on most phone screens does not work to wake up as when screen is off also the touhscreen is deactivated. Only some phones with special hardware can do. And on Samsung phone you can reactivate by the hardware home button. What are most of these promising "knock knock" screen on off apps bring ? The better apps, first bring the brightness down to the minimum allowed (25%) brightness, and then put a big 'curtain' button in front to further darken. If you look at the screenborder screen you can always see some backlight acivity shining trough. You have to push that big (curtain) button (double knock is popular) to bring you back to normal. Some of these apps only use the button curtain technique without reducing backlight to minimum 25% and so do not optimalise the minimum screen power consumption. I've seen one app that with a 'hack' that could bring the brightness down to nearly zero, but that is a dangerour setting ! What if the app hangs ? Where to push on that total black screen ? If there is no inbuilt resque system (by restarting phone a reset to 100% brightness) you're lost. Back to factory settings ? With dark screen ? Oh so very dangerous, also the reason that google standard only allows to set brightness down to 25%. Correct me if am wrong.

Hello guys,
Very nice observation Willy, thank you!
As a developer, during searching for options "how to turn on/off screen", I also read about this option - set darkness to zero and place some black layout on the screen. Partially working, but crazy.
Only solution I found and that works correctly is from my point of view this, that Locus use. So solution where app needs to obtain permission from system to be a "Device administrator" (System settings > security > device admin). Then it's possible to turn on and turn off screen directly from app code. So I only suggest - if you want to consider which app do this task correctly and which not (and least first decision which ...), check if app needs this "Device admin." access. Otherwise it will be on 99% just a black canvas, but with active backlight as 0709 was talking about. Just my two cents.

Gesture control does not seem to work when I have my Sony xz1 inside a waterproof transparent bag. I don't know what kind of sensor is being used for detection and whether the transparent plastic is blocking it. Would it be possible to have a function to detect with visible ambient light instead?

Hi Menion,
Yes the sensor and gesture control works when there is nothing between the hand and the phone. But when it is inside a transparent waterproof bag, the sensor will not detect. Like this kind of bag: https://klickfix.com/fileadmin/user_uploads/productimages/2717.jpg
