Double Tap To Wake failure rate?

[perpleSlerp]

I own both the 640 and 640 XL and I would guesstimate at least 60% of the time the double tap to wake doesn't work on the first try. Sometimes it takes three or for attempts. What about you guys and gals?

Same for me on 520

Same for me on Lumia 640 AT&T and T-Mobile versions.

I would say that I agree but I still tap continuously until it wakes up.

I think you have to double tap in the same spot to work. If you tap near the first tap, it won't wake up

It's iffy at best, not something i care for regardless.

Same on the 928. Takes multiple taps to get it often.

It's not a feature on the 520.

Works on the first attempt for most of the time on my 520.

About 10% of the times I double (triple actually) tap on my 730, the screen doesn't power on.
The fact is that those times that fail to light up the screen, I am carring stuff or I'm on a hurry and in general the thing just doesn't do what it should when I'm 100% depentend on it!
In my case most of the times it tend to not responding, is after long time of standby (being inactive in a pocket or something)
If I can recall correctly on W10m (especially on build 10166) the double tap to unlock work with more consistance.

But thank god double tap to sleep is working 100% so you never have to reach the button to lock it! (future found only on W8.1 update 2 and W10m)

If phone was in pocket, it won't unlock when you pull it out for few seconds. Try to wait 10 seconds and see, it'll unlock at first.
That's to prevent accidental unlocks inpocket. My former 520 had DTTW at all time working but often it unlocked by itself in pocket.

Turning glance screen to "always on" on my 640 xl pretty much solves the problem

try not to cover the proximity sensor while you do the double tap. this happened with me a lot, but i noticed that whenever my hand totally covered the proximity sensor or casting shadow directly on the sensor caused this trouble more and also while double tapping make sure that your other fingers are off the screen and not making any contact.if already you are touching the screen then double tap wouldn't work.I do all these and it workes perfectly, with i would say 95% accuracy.

 

[Joshwin]

are you sure you are not obstructing the proximity sensor while doing double tap, cos only when you cover the proximity sensor it doesn't work. when it is not covered it works 95% for me.

I had a 520 and I now have a 640XL rule of thumb so to speak on double tap to wake just double tap on the bottom half of the screen and you should have 100% success. As the above poster said don't have your hand/fingers shadowing or covering the sensor.

The double tap works too efficiently for me, it wakes up in my pocket sometimes, it's so annoying I don't even use it anymore

To combat this just set a password or passcode on it. I have a passcode and it don't unlock in my bag.

50%..... until I read this. Thanks!

Lumia 1520: I find that double tap to wake doesn't always work if I tap with my finger tip, but if I tap with greater surface area (my finger print) it always works.
