Unlock with fingerprint in one step ( immediatly avoiding display to turn on ) - LG G5 Questions & Answers

Hello guys, let's start saying that I own an LG G5 se, only because LG couldn't repair my N5x and gave me that...
Until "yesterday", I was used to unlock with my phone by just pulling the phone from my pocket while touching the fingerprint sensor, so by the time necessary to reach "my view/eyes" it was ready to go! And this habit is a die hard!
Now with the G5 se it's a pain: for my understanding the fingerprint sensor needs to have the screen powered on in order to work, so it result in waiting time or "double tap" the sensor as I'm used to touch it while pulling out from the pants!
So.... Is there a way to prevent the touch sensor from "sleeping" so I can unlock faster my phone like my old beloved N5x?
maybe some adb command, an app, but nothing that involves root as it's not available

On my H850 G5 I place finger on reader and it unlocks, even when off. Maybe it's an issue on SE or settting?

Are you saying that if you have the phone in your pocket and you touch ( not push ) the fingerprint you have the haptic feedback and the phone is unlocked and turned on?
I'm not having this (wanted) behavior, and I'm starting to think that it could be a feature/design, OR it could be something related to deep sleep that somehow disables fingerprint scanner.
I have no clue..

The unlock will not work in your pocket as the fingerprint reader is disabled due to the proximity sensor. If I pull the phone out and slide finger onto reader it unlocks. Having the unlock work in pocket would not make sense.

Ok, so it's a feature not a bug, it has 1-2 sec of delay until the proximity recognize that is pulled out... It is simply different from my N5X.
Thank you for helping me to "debug" this problem!

search is your friend
i havent seen any knock2 to wake that works on z ultra. care to point the link sir?
Ok, maybe I should have said search is my (or the collective forum) friend, as the question has been asked and answered several times that there is no knock/knock to wahe port for the XZU
We'll get the "double-tap-to-wake" feature in the 4.4 update according to the latest Sony 4.4 screenshots leak (xperiablog.net).

The idea came my mind when i read that the knock knock feature was ported to HTC ONE through flashing something , so I thought if this could be done for the XZu it would be awesome !
and since I am coming from the jailbreak family i couldn't do much research about the true capabilities of rooting !
It's not Knock Knock, BUT:
I use the Gravity Screen app. On stock settings, it will turn off your display when you cover the proximity sensor and you tilt the device a certain angle, like when you're putting it in your pocket.
It will wake it up again once the prox sensor detects that nothing's covering it, like when you take it out of a pocket, or flip open a wallet case. You can play with the different settings to make it work however you want.
In my case, I've set it up so that if my phone is lying on the table, I can just tap/hover a finger (or palm/entire hand) over the proximity sensor and the screen will activate. Just like Samsung's implementation, or indeed Knock Knock. In my case though, it just takes one...knock.
No more wear on the power button. For turning the screen off, I use the Screen Off app (double tap with Nova's gestures). Or if I'm putting the phone in my pocket, the screen turns off automatically once the top part goes down a certain angle.
Hope this helps.

I may have put you wrong. I dont think that there was a public release of the doomkernel with dt2w but there was a port by jackie099 (that has been removed from the OP) This is the thread http://forum.xda-developers.com/showthread.php?t=2740305

So only when you hold the phone to your ear the proximity sensor doesn't work?
Yea pretty much, I dont know if there's anything in the settings that needs to be adjusted but it is so frustrating now, please help me over come it. Cheers
I do not have your model phone. I have a note 3. Open the phone as to dial a number amd hit the menu button. I have an option to disable the proximity sensor so the screen would stay on.

Hey! Thanks for the help! When on dial and press on the menu button I don't have any settings coming up, I am assuming you mean a long press, but I don't get anything coming up. Cheers
Are you using a case? If so remove it and see if it helps. Also I read dirt in the proximity sensor could cause the problem. So blow air into the sensor to clean.

enter in service menu and recalibrate the proximity sensor , if doesn't work , it's a hardware fault

Might be a little bit late, but maybe for others
worked pretty well on my Samsung S4.
download the app "proximity fix" from the playstore and run it.
Job done.
Hope that helps you or anyone who stumbles upon this!
Solved!

I have just registered with xda forum so I think my reply may be quite late, but it's never too late, so they say
Anyway, I had the same issue with Huawei P Smart that I've just bought a few hours ago. And I got it resolved with the app called "Smart Screen On Off (New)", by LuuTinh Developer. You will find it on google play.
As long as you test the proximity sensor physically and it works fine, this app should help you get your problem disappear altogether
Happy calls (with a turned-off screen obviously )

Fingerprint scanner not working when always on display is off

Did you guys notice that you cannot unlock the phone when the always on display is off ?
Eg. You're keeping the phone in the pocket, you reach for it and take it out. The display hasn't yet fired up (while the phone is in the pocket the AOD is inactive) and at the same time you put your finger on the scanner. This should wake and unlock the phone at the same time but instead only the AOD comes up and screen is not being unlocked.
You can simulate this by locking the phone, covering the front sensors with eg your finger until the AOD turns it self off. Then place your finger on the scanner. The phone should get woken up and unlocked but it stays locked and off.
Anybody knows how to fix it ?
I dont use AOD ..... and mine works fine.
Relax. This is by design to keep it from waking up in your pocket, bag or whatever when you reach in for something else. You'd be even madder if you took your phone out only to find it had been woken up in your pocket and took 106 photos and placed four phone calls and sent texts to your friends that made them call the police because they thought you had a stroke.
It's not that I'm worried about accidental wake ups...
There's a delay between the phone enabling the fingerprint sensor after uncovering the front light sensors etc. which makes the phone to not register the touch on it for unlocking.

And now you know why it does that. You might not be worried about accidental wake ups but most people would probably be highly annoyed to take their phone out and find it firing off 20 photos. of pocket lint.

Both screens turn off from time to time

Hello. I have weird problem on my Lg V10 H901. On 2 to 3 days it happens for both screens to turn off, and you can't wake up the phone with double touch or with power button. And I'm sure that the phone is working because I can feel vibration feedback when I press and hold power button to go in to power menu. The cure is to pull off the battery and put back on and start the phone. For two or three times it happens to show white screen with little colored dots on it when you power on the phone. Otherwise the phone works normal. . No glitches, no heating, nothing. It just go off when it sits on desk and won't came back till you pull off the battery. I don't believe it's a screen because when it happens the both screens go off. Could it be the motherboard, processor or memory, or it's something wrong with proximity and light sensor? Any suggestions?
I had this problem as well until my proximity and light sensor completely stopped working. The sensor is not detected anymore but the issue stopped after.
I don't know about the cause but it could be because of proximity and light sensor.

Thanks for the reply. I am suspecting proximity and light sensor also. I am thinking to order a new one, it's like 9$.

By the way, I feel it is better without proximity and light sensor. Many problems were fixed after it was obsolete.

Question Finger print sensor responsiveness

Has anyone else had issue with the finger print sensor responsiveness, in particular with unlocking the phone. Sometimes it is super sensitive and I unlock the screen on accident and then sometimes its completely unresponsive and I have to unlock via PIN.
Usually after unlocking with PIN, finger print sensor works fine for unlocking.
I can confirm this behavior. XQ-BC52 with 61.0.A23.20

I've had the same problem with with older xperia 1, XZ and pretty much all the phones with fingerprint sensor.
when my finger are cold, when in the summer i'm a little sweaty, after eating something i have difficulty in unlocking phones. it's. a limit of fingerprint sensor.
also if for work you ruin a little your finger sometimes you have to register again a new fingerprint

Same here, also on the same model and firmware. But as opposed to @Evil_Sephiroth , I never had such issues on my older phones (Samsung Galaxy S7, Galaxy Note 9).
However, the fingerprint sensor seems to be a bit more consistent than how it was in September when I first got my Xperia 1 III. I hope they'll continue to improve it since it is still very inaccurate and frustrating.
Also, since the fingerprint sensor is always on, it would be nice if we could expand the status bar with a swipe on the fingerprint sensor. This was possible on my old Note 9 and it would be a nice feature on the Xperia 1 III since it's a really long phone.
