fingerprint not working - Verizon Samsung Galaxy S8 Questions & Answers

Had a couple Samsung app updates yesterday and now the fingerprint reader not working. Anyone else? Ideas? And phone has not been abused.

Well after I thought about it, restarted the phone and all good.

WHEN it happens again..
it has to do with the system "Fingerprint" app. Specifically the "finger sensor gestures", which is found under Settings -- Advanced Features. The app itself is a system app found in the regular application settings. But to get your sensor working again, try navigating to the finger sensor gestures, cycle it off, then on again and should work again. If you don't use it, just leave that feature off.
Mine used to do this all the damn time and it was so annoying having to restart it. I found cycling that feature off then on again would get it working again and quicker than a restart. I just leave that feature off now and haven't had any issues with my fingerprint sensor randomly stopping since then.

I've had this feature off from day one and my FP sensor stops working on occasion. Maybe once every couple days. There is another thread about it. I find that I type my passcode in once and by time I use my FP again it it's working.

Ambient display no longer working

Hi guys
Ambient display used to work for me and now seems to not ever show up.
I have a protector on the screen but it has a full cut away by the proximity sensor and so I dont think that is an issue. Also checked a sensor app and they are all working
I installed a notification app called edge colour notifications which I then removed. Issue seems to be timed with that but not sure.
Any ideas how to possibly get it working again?
Not rooted
Thanks

Since you're stock, you're kind of limited. Boot to recovery, select wipe cache, reboot.
Clearing cache didn't work but I think I figured it out.
I'm using a app called Automateit which runs phone actions off triggers. I turned it off within its settings and now ambient seems to work. Tested it twice now turning the app service on and off and seems to work. Hopefully that's sorted.
Have another strange issue as well where if I have screen lock enabled and reboot the phone, when it reaches the lock screen it goes into a weird loop on the lock screen and requires rebooting as you can't unlock. Have to reboot many times before it will let you in without this loop. Disabling the lock screen seems to stop this. Anyone else had this?

Fingerprint sensor issue

If my phone is sitting on the desk and I pick it up to unlock, the fingerprint sensor will only detect my finger on the second press. Once I've got it in my hand and lock it, it will unlock every time. But if I put it back down and pick it up, it will only work on the second press. It happens every time.
Anyone else found this?
I tested few times but I couldn't reproduce your finding.
Maybe you have activated some of the movement control settings, on my phone I don't have any.

I haven't enabled anything as far as I know. I turn most things off I don't need, especially gesture related as I never use any of it. Perhaps it's faulty somehow. I guess now's a good time to get it replaced due to the hulkified display.

Serious practical problem lock screen

Strange thing is happening recent to me...
Namely, while using headphones while talking on the phone, the unit gets unlocked while in pocket and problems arise with spontaneous keys getting activated.
If even cannot be explicitly locked by pressing the power button.
Have not found a solution to this problem, and it's strange why the proximity sensor does not work in pocket.
Cannot remember whether this was previously, or is it since last ROM upgrade.
Anyone having same problem?

Yep I have the same thing... Today my pocket took 9599295 pictures and movies.. also when I'm a bit sweat my pocket dial random numbers. I've noticed that when screen is touched and disnt recognize fingerprint then whole lockscreen shows up and its easy way to random open dial or camera... Its rly anoying, because I dont want to hide phone screen outside of the skin. (Its easier to break screen if I hit something with my leg.)
Dunno why it doesnt use proximity sensor to recognize that phone is in the pocket like every other brand... :/
Do you have the double tap to wake up activated?
I had this problem a while ago and it was the double tap that played all kinds of tricks calling emergency and taking pictures in my pocket! Disable double tap to wake up screen and the problem goes away.
Disable the fingerprint icon on when the screen if off.

Tried everything but the problem is eventually still there. Actually I've found a bug, namely the display will wake up once touched several times near the center of the fingerprint reader. Try it yourself.
Not nice - cannot avoid to happen it sometimes even if all options are disabled.

I didn't have this problem. If I try now and touch the part with the scanner, doesn’t have to be just the centre of the scanner, rapidly around ten times the lock screen will turn on, but nothing happens when I touch the shortcuts. Perhaps they are disabled, so the only thing that happens if the scanner is touched again is that the numpad to unlock with pin appears.
This is not good as it may severely affect battery life if it happens a lot. This clearly must be a bug!

Even worse, since it is happening all the time while on a call via BT and my phone is in the pocket. I am now thinking about to switch over to my old MI8...
Cannot understand why the keyboard is not disabled in the pocket. Seems so easy to do it but it's as it seems on.

My only solution was to buy a flip case. At first, I disabled the fingerprint reader by removing all fingerprints and setting up face recognition, but this didn’t fix the problem you are talking about. I don’t really like flip cases, but the Nillkin QIN Smartcase is rather good.
So now I ‘m eagerly awaiting a fix from Xiaomi so I can strip the Mi9 again!

Where can the fingerprint icon be disabled? Thank's.

Disabling the fingerprint icon has no effect on the problem we are talking about here. The only way to make the problem go away is to remove all the stored fingerprints thus disabling the use of fingerprints all together. This will shut off the fingerprint sensor doing away with this problem in a crude way.
If you really are looking for a setting, please use the search function at the top of the settings.

How to turn off fingerprint scanner activating on lift after new update?

Anyone know if there's a way to disable the fingerprint scanner activating any time I pick up the phone now? Never did that before the update, it's pretty annoying. Already have lift to wake turned off, but that doesn't fix it. Went through every setting and didn't see a way to fix it. And it's not the lift to wake option, the whole screen doesn't turn on, just the fingerprint scanner and icon. Seems to be making my battery life way worse.

Because Blu cust support has not duplicated it, others with update didn't duplicate it.
Makes it seem like just your phone.
Did you try to factory reset it.
Fully. Remove saved fingerprint remove accounts,
Reboot to recovery and do factory reset. Setup phone again

Late reply I know but I found out how to disable this option.
In the settings go to:
Display->Ambient Display
Turn off the option for New Notifications.
I have no idea why it is called this as new notifications (SMS at least from my quick test) still wake the screen,but the fingerprint sensor no longer shows when you lift or move your phone. Completely mislabeled but hey at least you can turn it off.

Proximity sensor problem

hi guys, i noticed that my phone's "lift to check" and "double tap to wake" aren't working sometimes, and the screen went black when i make a call. therefor i downloaded sensor test app and figure out those are caused by proximity sensor stopped working occasionally, especially when i take it out from my pocket, i had to restart my phone to make it works again.
i searched over the internet and tried all the ways but still no luck. Action taken included boot to safe mode, clear the cache of phone app/ google framework/ google services, android ambient and etc... and i also reset the app preference, download sensor calibration app, factory reset, yet, the problem still appear. i have used my phone for more than a year, and this issue was just suddenly poped out recently.
appreciated if anyone here could provide a solution. Thanks
