This is just an app i found out while redditing.
So all of us who have nougat know that when we double tap a notification icon while in AOD it turns on the screen and brings you to that app right?
Well what this app does is that it always gives a turn on icon notification on the AOD screen andif you double tap it it turn on the screen and it doesn't send you to a specific app it just turns on the screen kinda like double tap to wake.
I installed it a couple of hours ago and it works just fine! :good:
So i think so far this is the best way to unlock the phone without pressing any hardware buttons.

This can be done using Tasker too, but since that app is free that's a nice alternative.
This is exactly what I am looking for. Great app ????????
could be very nice without strange autorisation for network access

Hi CoolRaoul!
Could you please describe how to do this with Tasker?
Thanks!

It's pretty simple indeed,
All you have to do is to set up a "Display Off" profile whose enter task creates a notification and exit task cancel it (since double tapping on any existing notification wake display):
Code:
Profile: DisplayOff (168)
State: Display State [ Is: Off ]
Enter: DisplayOFF.enter (35)
A1: Secure settings [ Configuration: Read system aod_mode Timeout (Seconds): 10 ]
A2: Stop [ With Error: Off Task: ] If [ %stsettingvalue = 0 ]
A3: Variable Set [ Name: %msg To: Wake Device Recurse Variables: Off Do Maths: Off Append: Off ]
A4: Notify [ Title: %msg Text: Icon: hd_aaa_ext_import Number: 0 Permanent: Off Priority: 3 ]
Exit: DisplayOFF.exit (214)
A1: [X] Play Ringtone [ Type: Notification Sound: Unlock Stream: 5 ]
A2: Variable Set [ Name: %msg To: Wake Device Recurse Variables: Off Do Maths: Off Append: Off ]
A3: Notify Cancel [ Title: %msg Warn Not Exist: Off ]
A1 and A2 steps are purely optional (require Secure Task plugin), just a small optimisation which skip notification creation if Always on Display is disabled
For the "double tap to lock" (even if t's not the subject of this thread) I use the Nova Launcher gesture.
When my screen is off I swipe to enable screen feeds and then put my finger on menu button then the screen turns on. I enabled finger print and I just put my finger on menu not push it.

Works fine too and do not require any 3rd party app.
This require to swipe up then down (the thread subject was about "double tapping on icon")
Anyway, could be a matter of taste
Interesting app, but since I still have to swipe the screen, even with smart lock enabled, it's utility is somewhat limited. If double-tapping would take me right to the last app, instead of the swipe screen, it would be great, but right now it's easier to just use the hardware button and fingerprint.
I can see this being very useful on the S8, though, with it's stupid rear-mounted fingerprint sensor.

I have smart lock with my gear s2 and with location in my home and it does indeed send me straight to my last app without asking me to unlock or use fingerprint, i don't know why it doesn't work with you.
nice app man!!!
i start using it
Not that useful at all. If only we could double tap the notification icon so it can expand or be shown like ambient display instead of getting us to the fingerprint/pin prompt...

Its the same you have been doing since you got the phone... but now instead of pressing the home/power button you don't need to press any actual hardware button, i personally always have the feeling that i will damage my hardware buttons if i press them a lot which probably isn't true but i like it not having to press any button now.
Besides if you ever had a lg phone with double tap to wake (i had the lg g2) its exactly the same thing, you double tap the screen and it just gets you to the lock screen and you have to nomally unlock it.
The only way to go directly to the home screen without anything else is for samsung to implement a fingerprint reader like all the ones available on newer phones where you only put finger on top and it will unlock.
Since i have a gear s2 and enabled smart lock with it i just press this icon's app on the lock screen and it gets me directly to the home screen without having to do anything else.

Do you have fingerprint unlock set, or just PIN?

Yup, fingerprint as primary and pattern as secondary.

Yes, you are right, that it what everyones is doing right now!
What I am trying to say is that it would be better if there was a way to see the notification before we unlock the phone.
When I receive a sms, an icon apears in AOD but no further info is displayed. And if I want to see the sender I have to press a button! Thats what is wrong in my opinion! Double Tap should awake the screen in Black and White (just like ambient display) and then we decide whether to unlock or not.
Even though the P2 can be considered large with a 5.5" display, the lower region of the screen is occupied by the on-screen navigation bar. While there's an option to turn off the navigation bar and use the fingerprint button exclusively, I still find this alternative lacking in many fronts:
1. I can't tell you how many times I return to the home daily; it gets tiring to always have to push down the fingerprint button.
2. You need to touch the fingerprint button for a second or so before the recent apps window is launched. If you've ever had the need to flip between apps quickly, you would know how irritating this delay is.
3. Because one button is used for three functions (back, home, recent apps), there's no way to quickly switch between apps (like alt+tab in windows).
4. I sometimes find myself lying on my side, holding the phone with one hand, and finding it almost impossible to reach all the way down to the navigation bar, let alone the fingerprint button.
Fortunately, I have a solution that I believe addresses all of the problems above and that is to navigate the phone through the use of gestures.
I've been using GMD GestureControl for about a week now and I think I've found an optimal combination of gestures that don't only work but are also intuitive to use. There's nothing you can lose by giving it a try.
It can take a bit of time to set it up the way I have mine set up. So, if you don't feel like spending some time doing it yourself, you can just "restore" my "titanium backup" backup. Download it from here. Just extract the zip file and copy the content into your "titanium backup" folder. Open "titanium backup" and restore.
If instead, you would like to set it up yourself, here's how I currently have mine set up:
1. After installing the app, the first thing to do is go to "Device Setup" by pressing the menu button on the top right corner of the screen. Change your values to the one you see in the first attached image below. Then go to "Settings", and change the values to those in the second attached image.
2. To create a gesture: press the plus button > Select a gesture > create path. You can see all the gestures I created in the third attached image. Recreate all of them.
3. You can decide which region of the screen a gesture is detected by choosing the appropriate zone in the "select starting zone" option.
4. You need to go to "advanced options" (attached image no. 4) at the bottom of the screen to decide whether or not the gesture can be triggered when the keyboard is active. I have most of the gestures disabled when the keyboard is active because I sometimes swipe to type and I don't want to accidental swipe to trigger something. For this reason, I have duplicated most of the gestures for the only the top half of the screen (above the keyboard) so that the gestures still continue to work when the keyboard is activated.
5. Make sure you enable "evaluate on release" on all gestures so that a gesture is only triggered after you lift your finger off the screen.
If you've gone through all the steps, it's now time to start trying things:
1. To open resent apps, just make a small ^ sign anywhere on the screen.
2. To go home, just make a small V sign anywhere on the screen.
3. To flip between apps, just make a small < or > sign anywhere on the screen, starting from the top.
4. To press back, swipe away from left or the right edge.
5. To open the launchpad, swipe up on the left or right edge.
Good looking out. I really like this option.
Is anyone else having the same issue?
Double tap only works when the ambient display is showing (the clock before the lock screen).
If you turn off ambient display all together, double tap does not work.

Double tap works for me without ambient display being on.
I'm on stock 58.0.A.28.51.
Looks like it's one of the system apps whose permission I modified.
I just did a factory reset
It seems like a common issue with this phone. My tap to wake has never worked properly and it's driving me insane. Tap tap tap TAP TAAAAP, then it works. Sometimes.
Does anyone have a solution for this before I throw it out of the second floor window?
Yeah, that's one of the very few annoying things. I wonder if it has to do with the screen protector? There have been user reports of lower touch sensitivity (mostly at the edges of the screen) due to screen protectors.
Double tap isn't working again when ambient display is set to "OFF" and I have not messed around with system app permissions.
I did verify that 2x tap is working after I debloated the phone with AD set to "OFF". Not sure what has changed since then because I have not used this phone since debloat.
More details:
-2x tap will only work when AD is showing
-for as long as AD is showing that clock, 2x tap works
Double tap and lag-free notifications should work much better when you set "Smart activation" in Ambient display settings (lokk in "When to show Ambient display" settings).
Same issues, tried many things mentioned here and more ... you'd think simple things like this would work flawlessly in a high end phone. Really tired of digging and digging in the phone and online to find solutions, so frustrating. Sony will have to make something extraordinary in the future to convince me to buy another phone from them ...
It's way too long time have passed from the last post, but I was wondering about the same issue of double tap when searching for the answer had led me to this topic. I've recently bought two same phones, not Sony but Nokia 5.4 with Android 10 and stucked in gesture unlock too. Though this topic didn't helped me, later I've found the solution by myself and eager to share the way that did worked for me with everyone.
So, if the double tap to wake up the screen suddenly stopped working, try this:
1) go to Settings-System-Gestures
2) find the "double-tap wake" option and turn it OFF
3) back to home screen and lock the phone with the power button
4) unlock the phone with any way
5) go to Settings-System-Gestures
6) find the "double-tap wake" option and turn it ON
That's all, your favorite unlocking must work again (well, both my phones were healed). Good luck! )
Inversely, you can't disable tap to wake on the AOD.
Infuriating.
In any case, 3-taps always works for me
Including this phone and Pixel 2XL.

Hi!
I have the same issue. After unlocking the bootloader the fingerprint sensor does not work anymore. I am using the EMW Image in version 0904. All other features are working fine. But the fingerprint registration failed everytime.
If someone have an idea or solution, I would be happy!
I found the solution on: https://forum.xda-developers.com/t/...-gcam-buffer-fix-and-fingerprint-fix.4296789/
"Fixing your fingerprint reader
After the bootloader unlock, you will no longer be able to register fingerprints. This can be fixed using the following steps:
Launch the hidden service menu by dialing #*462633*#910# (might require an inserted SIM card)
SVC Menu -> Handprint -> HandID Logging "ON"
Go to the start of the menu and then navigate to "Device Test" -> SAAT -> Manual Test -> Optical FingerPrint Test
Press SEVERAL times firmly on the green button until it says FAILED, confirm and exit the menu
Go to settings and set up your fingerprints!
AFAIK, you can now disable "HandID Logging" again"
Thanks but the scanner is stopping the registration at 35% - everytime. Seems to be a software problem. :-(
I found the solution when you unlock the device it completely loses the calibration of the fingerprint, it is necessary to calibrate again using a digital calibrator, or a white sheet, a sheet or very dark object and finally the finger itself steps
NOTE: THE DEVICE MUST NOT BE USING ANY TYPE OF SCREEN SAVER OR THE LAST PART OF THE CALIBRATION WILL FAIL
1 - access the menu of velvet 4g engineer with code 462633*#910#
2 -SVC Menu -> Handprint -> HandID Logging "ON"
3 - Go to the start of the menu and then navigate to "Device Test" -> SAAT -> Manual Test -> Optical FingerPrint Test
4 - the first step you need to place a white bond sheet on top of the reader or the white part of the digital calibrator
5 - the second step is to place a black sheet or some black object that completely covers the fingerprint icon, or again use the black box of the fingerprint calibrator
6 - lastly do you use your own finger to cover the scan or do you use the part of the digital caliper that mimics the surface of the finger
7 - after all this you can go to the settings and add your fingerprint again
8 - I restarted my device and the HandID was already turned off, if your device stays on go back to step 2 and mark the option with OFF

Hello everyone,
I just wanted to make a quick post on how to access the diagnostics menu and how to calibrate some of the sensors. It is the same as other Galaxy devices:
1. Go to the phone dialer on the watch and dial *#0*# (hold "7" to dial "*" and "9" to dial "#")
2. This will bring up the diagnostics menu. Scroll down and tap on "Sensor."
3. From here you can calibrate various sensors by tapping the "Selftest" button for each corresponding sensor.
*Make sure your watch is on a flat surface and is perfectly still while calibrating.*
4. To go back/exit the menu, swipe right.
I know it's sort of old news for other Galaxy devices, but I hope that helps.
Cheers!
