Doubletap2wake randomly/periodically does not work?

Why does doubletap2wake randomly stop working? It has nothing to do with phone being idle, still doesn't work after movement, have to unlock to get it back to work again.
Is this because of deep sleep or power saving mode enabled in sense?
Is my M8 defective - is this a hardware issue?
Running ARHD and ElementalX 0.18. Had the same issue on stock kernel - can't remember if I had it on stock ROM but someone else told me he had the issue too on all ROMs.

This is a stupid question, but I have to ask: Are you sure that you are holding the phone vertically so that it is in portrait mode?

sometimes i notice that the double tap to wake won't work because i have some stuff on my screen or something that registers as a screen press. i'll have to wipe my screen down.

It's all in the finger action. One to wake the sensor at any corner of the phone, then 2 deliberate taps, not 2 quick taps, on the bottom half of the screen.

I have this exact problem. At least 1-2 times a day, motion gestures will stop working and I have to use the power button to turn the screen on. I have tried everything when this happens (making certain phone is in portrait mode and held straight up, shaking the phone, tapping the corner of the phone before doing the gesture, etc.). I am well aware that the phone has to be moved before doing the gestures. This is my second HTC One M8 from T-Mobile. The first had scratches all over the back out of the box so I exchanged it. I don't recall this ever happening with the first phone. Maybe some app is messing things up? Could this be a hardware issue? I'm hoping it's a software issue.

Make sure you don't accidentally swipe up while the screen is off as this seems to lock the gestures out.

Really? I haven't heard that being mentioned before. It's possible I accidentally swipe up just a bit when I'm trying to DT2W. Has anyone else mentioned about accidentally swiping up while the screen is off and it locking the gestures out here on XDA?

I've noticed this as well, but only with the double tap(swipe up or to the side always works). I would say mine only does it about 2% of the time though so I haven't been too concerned about it.

Hi guys. I just wanted to report that I updated to the latest stock 4.4.4 OTA 4 days ago. I no longer have any problems with the gestures randomly not working (including DT2W of course). I'm a happy camper =D

Also make sure when you pick it up the meat of your thumb or other part of your hand is not touching the screen. I've caught myself doing that a few times.

Your title pretty much sounds like it is referring to my brother.

I am having this problem too with or without the dot view cover
Sometimes it does't wake up... it's like its in deep sleep like the OP is saying
Any help

two large speakers and some gabba techno should do it
Lol think the phone needs to be at a slight angle when using double tap. i have noticed before when my phone is flat on my desk at work and the screen has been off for a while, its seems to be in deep sleep mode, however when i pick it up, double tap works

It happens to me maybe a couple times a week. I reboot, fixed.
Poop happens is my explanation.
I wouldn't be very concerned. Things get screwy in the system every now and then, that's all.

Whenever it does that, I just rub my finger across the proximity sensor back and forth a few times and then try the double tap again and that always works.

Anyone have Gravity Screen - On/Off working on the G4?

I have the Verizon LG G4 vs986 running 5.1 (10b) but I've been unable to get Gravity Screen - On/Off 2.3.1 to work as it's not turning the screen off. Does anyone have this working on the G4 and can you share your settings? Thanks!

Been using it since the beginning (and G3 as well). After removing Power Nap Alpha 0.7 working flawless. Have you enabled Administrative Permissions?

Yes, enabled that. Can you let me know how you have the settings for the program setup? I was able to get the screen to go off once when I first installed it but never could get the screen to turn on and I have the PIN enabled lock screen.

On
Any Direction = Check
Lying Face up= Check
Turn off by proximity = Check
Turn on by proximity = Check
Keep screen on by Motion = Check (sensitivity 70)
Booster = Check
Running During Call = Check
Notification = Check
Low Priority = Check
Start at boot = Check
I have the unlocked version so I also have some apps whitlisted
Device Administrator = Check (for both delayed lock and regular screen off permission, 2 separate)
All the rest I have UNCHECKED

Thanks! Think you covered everything except what do you have for the following settings:
Pocket Sensor Angle
Landscape mode
Table Sensor Angle
Turn Screen ON by Motion-Timeout
Turn Screen ON by Motion-Sensitivity
False Turn-On Protection in Pocket
It seems my screen is turning off because of the 15 second display timeout in the phone settings and not because of Gravity, what do you have for the phone's display timeout settings? I changed it to always keep display on and the screen does go off, but doesn't turn on until I tap the screen.
Is the screen supposed to turn on by itself or does one have to tap the screen?

Pocket sensor = 60 (default I think, it becomes inactive with Any direction checked)
Landscape mode = Unchecked
Table sensor angle = 2
Turn on by motion = Unchecked
Keep On by motion sensitivity = 70
I don't have a false turn on protection in pocket option
Screen timeout = 15 seconds
On my device T Mo G4 H811 no tapping of screen required, all screen on and off functions are performed by Gravity (every now and then it doesn't read the proximity sensor, but 99% of the time it functions as it should).
The default setting should have gotten you working, all these setting are more of a fine tuning to your liking rather than actual functionality of the app itself. Have you tried uninstalling, reboot and reinstalling? Proximity sensor working? Not sure what else you can do other than contact the developer. I had and issue a couple versions ago and it was addressed fairly quickly with an update (I'm sure I wasn't the only one in that case).
Hope this helps you out.

I think once you select Any Direction (Flip Cover), the angles for both Pocket Sensor and Table Sensor becomes inactive, Turn Screen OFF by Proximity becomes inactive as well. I actually figured out the problem as it was the app that was turning the screen off but I am running Power Nap as well which puts the phone in deep sleep mode so I had to add GS to the exclude list in Power Nap before GS worked correctly and turned the screen back on. I already tried uninstalling from the app, rebooting and installing earlier but the problem was Power Nap. I have the unlocked version and it does have the false turn on protection option which is the last option under the Turn Screen ON by Motion section.

Yeah... Power Nap. Loved it on the G3 but on this phone it still has some issues. I stopped using it because even though I whitelisted certain apps some of those whitelisted apps actually weren't being allowed to remain active. Gravity wasn't one of them but Root call blocker was and boy was that a treat at times.
Glad you got it worked out.

Trial and error... Root Call Blocker worked fine (whitelisted) when the screen was on but failed to work when screen off. What turns off my apps when screen off? Power Nap. Disable Power Nap and Root Call Blocker worked fine (screen on and off). So my conclusion was Power Nap even though whitelisted Root Call Blocker was failing to leave that app active.

Interesting, in my case, Powernap didn't put any app to sleep as before yesterday, my battery would last 2-2.5 hours with the screen off then I started greenifying everything except those I know that needs to run in the background and now the battery lasts 9 hours with Gravity Screen. I left White Pages ID without greenifying it.

[APP][Android 6+] Ambi-Turner - wake up ambient display

I've created an app that wakes ambient display when you take the phone out of your pocket or if you have the phone face down and turn it over. The app is in addition to Google's ambient display and does not change your lock screen in anyway.
I added a few other paid features for lift to unlock, wave to unlock, pulsing at an interval, and battery percentage display on the ambient display.
I have a thread going on the Pixel XL forums and a number of people have been testing it out. I think it's stable enough to start spreading the word.
Please let me know if you have any suggestions or run into any problems. Thank you!

I'm interested, but it appears your link is dead.
Edit: found it in play store. Went ahead and got pro for lift to wake.

Thank you! I fixed the link...cut and paste truncated the link.

I'm testing it since four days and can absolutely recommend it.
No battery drain here at all. Proper functionality and even more options with every new version.
Keep up the great work.
Edit: do you have PayPal? I'm gonna hook you up with a beer.

Haha, thank you. The app support is more than enough thanks!

Just bought the pro version. Coming from a note 7 and missing that ambient display, this great app will do.

Looks great.

Thank you very much sir

Trying it on a Nexus 6p. So far i'm loving it.

Bought pro, thanks!

So I've done some limited testing with the app white listed from doze and so far it improves the responsiveness significantly. I don't know the battery impacts yet, but if it's not noticeable I'll add code to prompt users to white list it.
Other upcoming changes:
Advanced settings to adjust wait times for how long the phone has to be in your pocket or laying flat before a wake can occur.
A pulse option that initially pulses faster when a notification comes in, and progressively shows down until the timeout.
Possibly change in lock screen battery indicator appearance.
Filter on laying flat thresholds. I suspect the accelerometer incorrectly reports the phone tilted while it is laying flat on occasion.

Just bought the Pro version, thanks for the nice app.
Unfortunately the ambient display doesn't light up on my Pixel if the phone is unlocked, e.g. by SmartLock. Typically, I have the phone lying next to me on the desk at work or at home und the phone is unlocked by location based SmartLock. This is where I would like to see incoming notifications without touching the phone. Do you think this is possible to implement?

Doesn't work for me.
More important (maybe only for me): the screen doesn't light up without interaction if the phone is unlocked by smartlock. That's the same behavior as with the ROM build in ambient display feature. It only lights up the screen when the phone is locked.
Thanks a lot for looking into that. This would overcome the disappointing original Google ambient display implementation!
If i can help somehow (testing,...) please let me know.

Tested again..
Ambi-turner enabled.
In display settings
Ambient display : on
Display timeout : 15sec
Security settings:
Pin lock screen after 10min
On/off button locks immediately
(I'm not on an English version, hope the translations are understandable)
The phone is in an area where is unlocked by location based smartlock.
Test 1: wait for 15sec until the screen switches off, wait another minute, send me an WhatsApp from 2nd phone: i hear the notification sound, screen doesn't turn on. If i turn on the display using the on/off button i am on the home screen.
Test 2: switch off the screen by on\off button, (i can hear the lockscreen notification) and send me a WhatsApp from another phone. I hear the notification sound, screen turns on and shows the message. If i turn on the phone by on/off button I'm on the lock screen.
Pixel, version NDE63H

Just bought pro - nice job!

I' ve just tested it on my Nexus 5 with PureNexus 6.0.1 rom. PN has ambient display function in settings but it doesn't work because Nexus 5 doesn't have pick up sensors or pocket sensors. Therefore I've been looking for some solution how to wake it, for example cmactions-wave to wake or similar. For the previous period I've been using GravityBox but it's battery hungry.
I see now that ambi-turner works also, so testing it ATM...
nice work...

Thank you. I'm posting an update soon. I'm testing a new mechanism that is waking the screen up much more reliably than the current version.

Screen not turning on sometimes

Has anyone has an issue where the screen won't turn on after using the fingerprint sensor? I can feel it unlock but I sometimes have to hold the power button until the power off/reboot menu comes up which then starts the display up from being all black. Have Magisk beta and Xposed installed so maybe that's the issue?

Is AOD on or off? What happens when it's on?

AOD is on. So what happens is if the phone is on my desk and AOD is showing time, it'll show the notification briefly then just go black(nothing is covering proximity sensor and notification light is blinking). I then usually have to either do the power menu trick I mentioned or just restart the phone. If it's in my pocket on the other hand I'll pull it out and it'll be black with a notification light.
Oddly enough it usually only occurs with Snapchat so I think it may have to do with having snaptools installed?

Quite possibly so. I know nothing about snap face, snap chat, or whatever these social media apps do. Although, you may try clearing the app data and cache on said app to see if it helps. No guarantees though. As is the case with many things android! ??

I've had the same issue ever since I installed, I believe, the nav bar immersive mod. Not sure, around same time. I was able to hurt power button twice for camera and that would pull it up and u could switch back to screen. I don't have xposed or Snapchat, so I don't think either of those are it. It's random when it happens to me.

I've had similar issues. I'm not rooted and have never used Snapchat or AOD. I do use immersive mode for some apps so I've thought that might be causing it. Like stated above, I can get the screen to come on my double tap to open the camera or just holding the phone face down and tap the back a couple times then flip back over and the screen comes on.

I'm also having this issue. Ambient display seems to prevent the issue for me. If I reboot the issue is gone for a period as well. Not rooted but have immersive mode acrive via nav bar hider.

Ok so a little more testing. When Ambient display is set to always on, I have no issue, maybe a slight lag when waking/unlocking. When ambient is set to tap or pick up i get issues, when ambient display is set to off at all times, i have no issue. Plugging the phone in to charge seems to force the issue to happen.
Edit: Seems that even with ambient display off totally the issue pops up. Strange thing is if i unlock the phone and take a screen shot, its totally black.

I to have this happen and like sportytony I use camera to wake device. Sometimes that too takes a bit. Most of the time when it finally does wake there will be a notification that systemui isn't responding. So I wonder if it's related.

Ok, I've been having this issue happen multiple times a day. I use this immersive app: https://play.google.com/store/apps/details?id=in.tsdo.elw
Since I have turned all ambient display options off and made sure that System UI is unchecked in the immersive app i haven't had an issue at all.

Its definitely related to system UI, com.android.systemui to be precise
i used to try to set up Power Nap on this device, but it can't find System UI in app list, make me unable to whitelist it, thus causing same issue like yours,
Screen wont turn on after sleep, since System UI wake up is blocked

I was using hide navbars and had this issue
I uninstalled and never had that problem again
Sent from my Google Pixel 2 XL using XDA Labs

Didn't expect all these replies but I'm going to try to untick system UI and see what happens. Thank you all!

Another sensor bug(minor one)

I am having a small issue since I bought this Pixel. Since Nexus 4 I am using double tap to wake by using apps, root or original hardware. So pixel 3 xl came with this feature out of the box and happily using it.
But sometimes it was not working and I was saying "nah it ok, it happens from time to time probably deep sleep issue" and using power button .
Then I also started using screen "always on" feature and realize even always on is active double tap not working, until I cover proximity sensor on and off, and voila! double tap works.
It seems like proximity sensor is latching itself off but does not turns off "always on" Also similiarly "always on" is off as if proximity sensor is shutting it off but when I check I see some whatsapp messege notifications.
It is a weird bug and even after clean flash of android 11 did not solve it(although it broke android auto wireless )
Does anyone else have it ? it is a general bug or hardware issue ?
