Double Tap Feature to Wake is Faulty - Causes Screen to Wake without Double Tapping - Samsung Galaxy S10+ Questions & Answers

I noticed if one enables Double Tap to Wake feature, the lock screen wakes in one's pocket without double-tapping it. It appears if the screen is too sensitive to touch and wakes up as if one were double tapping it.
I normally carry my phone in my shirt pocket with the screen facing inwards and have noticed this happens often when walking or standing up that the screen wakens with double tap feature on.
I have now disabled this useful feature to save battery.
Please check if this is happening to you as well and post your replies.

I also noticed that, but if I turn off the wake when you lift it feature the screen does not come on. Dbl tap works fine then.

Also def make sure that accidental touch protection is on

My lift to wake is off and still does it.

This is on and it still does it.
The only time it does not do this is if I place phone in my pocket with screen facing outwards. Annoying as I prefer screen to face inward for better protection.

Tip: No circle case needed to check the time

I haven't seen this tip posted yet so I thought I'd put it up.
You don't need to have one of those fancy circle cases to see what the time is. You don't even have to press the power button or tap the screen. While the screen is off, swipe your finger from the top to the middle of the screen. It will show you a clock that disappears as soon as soon as you lift your finger. It will also show you your notification bar. So if you have your lock screen set to not show you any notifications, you can use this method to see if you have a text or email or whatever, with out having to unlock your phone.
EDIT: This doesn't appear to work on all phones. YMMV.
You can do it from the middle of the screen also. Just slide your finger downwards.
And of course... it doesn't work on the at&t model.
Doesn't seem to work for me...
Is it double tap then swipe? I'm trying all sorts of tapping combinations and nothing interesting is happening, other than the screen turning on as normal when you double tap
Place thumb on screen, slide down. The screen has to be off of course.

-Turn screen off
-Put finger anywhere on screen
-Without releasing, swipe down
-Release finger
Is that right? I've tried about 10 times and I'm getting nothing. Is there a setting to enable/disable this somewhere? I might have disabled it by mistake
You have to keep your thumb on the screen. As soon as you lift your finger, the screen goes back to sleep. You should notice the notification light come on if its working.

It's kind of annoying. I found this awhile ago.
If you can't get it to work ya the screen, one-one-thousand,then swipe down.
I am amazed how people don't find this out on their own within the first hour of handling the phone.

Do you have an AT&T model?
Doesn't work for me. I have the international version with o2 ROM branding.

Oh, this only works with activated lockscreen. I had mine off.
In case you guys haven't read the instruction manual that came with the phone, all gestures and tips are in there.

Is there a way to disable this?
From what I've read, it does not work on AT&T models. And I don't think there is a way to disable the function, for models that have it.
And of course it's in the insanely small/thin font that you have no chance of reading if you're long sighted but aren't wearing your reading glasses (e.g. when you wake up during the night).

Correct. Your Lock Screen must be set to at least Swipe, and the screen must be locked at the time. It won't work on None, or if your phone hasn't locked yet due to setting a Lock timer after the screen timeout.
At risk of sounding dense, what is the main benefit of this? I rarely use this, but don't recall seeing notifications with it, at least not the sort that show you a text. I see a clock and the status bar at the top (signal strength, etc).
If I want to see the time, I could wake the screen up, including by double-tapping (so no need for access to the rear buttons). I see more notifications that way as well. One advantage of this would be if I'm in a dark room, and I'm trying to avoid disturbing people by lighting up the whole screen. But at least for me, that scenario is not common.
Am I just missing something about what makes this feature handy?
It's useless imo. And what annoys me more is the fact, that I can't turn it off.
I'm wondering if disabling swipe views and doubled tap to screen on actually increases battery life. My nexus 5 with custom kernel had that function but battery drain was significant.

Honestly it is just easier. Instead of Double Tapping to turn on, checking for notifications (if you have none or none you are concerned with), then double tapping off.
It is a quick peek. Shows you the time and notifications. You don't always have to wake your phone by double tapping. It is a 1 quick swipe gesture that turns the screen on, shows you relevant information, and turns off in 1 swoop.
I use it ALL the time. I have the Verizon model btw. Whether you use it or not, it is a super nice feature and just something that really adds to the convenience.

E-ink Lock Screen

Hello everyone,
So, I'm having a bit of a strange problem with my Yotaphone 2...
I did a factory reset on it a while back, and everything went fine, except now, when the screen is locked, I can no longer unlock the e-ink screen by dragging up the lock icon on the bottom of the e-ink screen. I have to use the hardware power button, which is a little bit inconvenient at times. I've spent quite a while trying to locate what setting got effected to make it not function, but with no luck. Anybody have any idea where I can turn this function back on?
It happened to me too, I think it was something related with the Lollypop update, but could be some setting that has changed and that I cannot find. However, I found that if I double tap before tracing the finger motion, it usually works. That's why I didn't look further into the issue.

Actually, scratch that... after your double tap suggestion, I started randomly tapping around managed just once to get it to unlock from a screen touch, but have not been able to replicate the movement so it happens again. What movement exactly do you use to get it to unlock?
Update:
Seems to be some kind of sensitivity issue. I can get it to unlock about once out of every 50 swipes. Less than ideal.
I leave the phone with the E-ink screen facing up (to prevent the gyroscope from switching sensitivity to the amoled display instead), then press twice the lock icon, and on the second time my finger touches the E-ink, I drag it up to the center of the phone. It took a bit of practice but now I can get it to work consistently. The double tap is because if the phone has been inactive for a while, it enters sleep mode, and it looks like that turns off the finger gesture recognition. Other possible explanations are that maybe you don't press the screen firmly enough, or maybe you placed some plastic sheet over the back display and that reduces sensitivity.
I noticed that the unlock gestures on the EPD work only when the phone recognizes that you've it in the hand or you're using it. So I take it and I unlock it effectively. Trying to unlock when it lays down and you haven't moved it for a while brings to your experience.
Thanks to both of you for the advice... unfortunately, neither seems to be doing the trick. Just a caution for any other people who are thinking of doing a factory reset - it seems to seriously impact sensitivity for the e-ink unlock, so be aware.
I never succeed to do slide up unlock even within 1st tutorial. Double tap unlock was the only workaround for me. Also activated glove sensitivity mode.

capacitive button issue.

Got a Op5 last month, but when I use the capacitive button, it double clicks at times resulting in opening the double click gesture instead of going back (which was the intention). Is that happening to you people as well? Or is it a hardware issue?

Are you sure you aren't double tapping without realizing it? The keys are pretty sensitive. You could always disable the double tap gesture you have enabled which would eliminate the issue.

No. I'm very conscious about it, so I've been pressing it once. My query is, if it's happening to you people too.
I could disable it, but I like it this way. Just wanted to know if it was a hardware thing or it happens to people in general.

Did the essential phone get double tap to wake yet?

Maybe with Android 9?

Nope
Reading the Elemental X thread, it seems like it won't happen without a big battery drain.
I have it working use Nova. Elemental. Double tap sleep and wake.
You an enable lift to wake as weel.
I found a generic double tap to sleep. Install this app, Pixel launcher mods. It allows one one to use system ui tuner, add a double tap to sleep widget zone, where the double tap puts it to sleep, and allows u to use the existing launcher with icon packs. The app is by quinns mighty apps and on xda labs
Oops, one failed, here it is.

I can get Nova to perform double tap to sleep. But there is nowhere I can find that Nova can be customized to do double tap to wake.
EX Kernel allows for sweep to sleep but again no sweep to wake or double tap to wake.
It's not as big of a deal on the Essential Phone given that the fingerprint sensor on the back effectively serves as a 'tap-to-wake' sensor. Just put your finger on it and it wakes up the screen and logs you in.
Double tap to wake requires power to the touch screen. This would require the screen to receive power which means it would be on. This makes sense on an LED screen since pure black on an LED screen means the pixels are off. On an LCD screen such as this phone has, you'd have a glowing, illuminated, black screen and battery drain since the display would have power going to all of the pixels.

Yeah good point, I had that thought too briefly, till I realized LG has been doing it for YEARS and still does it this day (I think) on MOSTLY its LCD flagships. I think my V30 was POLED, but outside of that all of the other ones were LCDs. Wondering how they did it...

that's not true only the digitizer needs power not the screen
the screen is actually 3 parts
the lcd/led
the digitizer
and the top glass

like I said above the type of screen makes no difference it's the digitizer that detects the touch

LG V35 double tap doesn't unlock screen, always on display doesn't work too - Help!

Hey guys, just got LG V35 updated it to android Pie, everything seemed fine, but i can't normally unlock phone. On main screen i can double tap and it locks, however double tapping again, doesn't unlock phone, as if screen froze. Also fingerprint button doesn't work either, i mean i need to press it twice slowly and only then screen turns on and shows lock screen, always on display also doesn't work. After simple restart those features work, but after a minute, same thing happening again. Also noticed, that if someone calls, screen is also unresponsive. Got phone couple days ago. Any solution ?

i had the same issue when i got mine. i think the screen protector i installed was the issue-it only had adhesive around the the edge and started to come off. i returned that one and replaced it with another make and haven't had the "knock on/off" issue since. good luck

I agree with tomdi1999 and also have used the adhesive around the edge screen protector but they interfered with screen touch sensitivity, it is as if having a couple of fingers touching the screen permanently while trying to double tap or unlock the phone via power button. If you have any glass screen protector, try removing the screen protector and double tap again to see if it fixes the issue. If you are not wanting to remove the screen protector first and want to do some troubleshooting, try run touch screen test via the hidden menu (assuming your v35 is AT&T version) by dialing *#546368#*350# (Be warned that some options in this menu can really mess up your phone so don't go around messing with options in this menu randomly) in the phone dialer. In hidden menu select Device Test -> SAAT -> Service Menu - Manual Test -> Touch Draw Test. If, with screen protector on you are having trouble doing this test, remove the screen protector, clean the screen, and do the test again. If you still have trouble with touch screen it is probably a hardware problem or could be software problem but unlikely though. Also, place a test call to someone and slowly place your hand to cover the ear piece and proximity sensor area to see if screen goes dark. This is to check if your proximity sensor is working properly because if it is not then it could be the reason that double tap to wake is not working, although it doesn't explain why your power button is responding slowly, that points toward the phone processor being busy due to ghost touches such as due to bad screen protector or just a faulty power button (but what are the chances of having a faulty power button and double tap to wake going bad at the same time lol?).
I remember that years back on LG G4 double tap function would stop working if you had the screen replaced or sent in the phone to LG for repairs such as repair for notorious bootloop issues and it turned out that there was a small rubber piece that went around the proximity sensor that people were forgetting to put back when replacing screen or doing other repairs which basically broke the proximity sensor. Proximity sensor is suppose to disable screen wake up due to accidental double taps such as when phone is in pocket but if proximity sensor is malfunctioning it will not let phone wake even when you double tap to wake it.
If you figure out what was wrong and/or fixed your issue, please do post back so it can help others. Thanks.
Edit: If you are looking for a good screen protector try Skinomi or Armor Suit wet screen protectors. They are not glass and are a pain to put on but once you install them and let them dry, they are awesome.
It helped me thanks a million!
wouldn't think ever it was the screen protector, thought one of my apps...
I've removed it and it was back to normal.
thanks again
