[Q] Face unlock stops working on EOS Stingray Nightly 40

Hi everyone...
Face unlock is pretty cool... but for me it stops working after a day or so. Running EOS Stingray nightly #40. It has been doing it on every nightly I've played with starting from the mid 20's.
For instance, right now, when I unlock I get a black box and the camera doesn't turn on. Other times I won't get a box at all... that is until I reboot and things work again for a while. I can't tell if perhaps the rotation (going from landscape to portrait) is what's screwing it up, or if its just being buggy.
Anyone else experiencing this symptom?
Thanks
-Mike

What is your Xoom overclocked to? Are you allowing it to switch between portrait and landscape automatically?

I'm running with the same settings. I can open the camera just fine without issue. Going back to the lockscreen,its just a black square... when I reboot, its fine again...

try this.
delete /system/vendor/pittpatt folder
turn off facelock
reboot into recovery.
clear cach and dalvik cach
reflash gaps (should be ver 10.4)
reset up facelock.

Nope. :-( It worked all last night. Took it off the charger this morning and I don't even get a black box. When I unlock it, I get a message that says "unfortunately face unlock has stopped" or something like that. Ughh. Good try. :-(

if i restart the phone its work for few mintues

Weird because I don't have this issue. However I had to perform a factory data reset through stock recovery because my internal storage was reading 16gb not 32gb. I mention this because maybe that'll help u. Plus I'm completely stock so far.

Have the same issue. Its so annoying. My brother and i did the updates on 2 phones. Mine has the issue, his is working fine. Any solution

I'm having the same issue, I pushed the OTA update via ADB first and has this issue. Then i tried A factory reset and still had it. Then I tried flashing the factory image using fastboot and I'm still having this problem. Everything else seems to be working great.

Do you guys think its an app related issue?

I don't think so, i booted into safe mode and still had this problem, unless the issue is being caused by a native app.

Yeh tried that too. Same thing. How come my brothers phone is fine tho

I don't know man, hopefully someone with a bit more knowledge will be able to help us out, glad I'm not alone though lol.

I fixed mine! I just needed to re-install my factory image manually. Follow the directions in this thread and use method 2.

I thought I do that on my phone too with no success. I used the nexus toolkit tho. Does it make a difference

*EDIT*
Never mind, it's still broke, I let the phone sit for about an hour and when I came back the sensor wasn't responding again.. I give up.

what if it is an application that is causing this?

No sorry, it took about an hour but the problem came back. I didn't have any apps downloaded yet and it still happened. I would try though, can't really hurt anything. Maybe it will work for you. I'm just tired of rebuilding my whole phone every time, I'm going to ride it out maybe someone will figure something out.

Can you guys try disabling google play services. I have it disabled for 30 min now and looks like its kk

Is yours still working? I just tried this and besides making the phone generally unusable it did nothing, sensors still didn't work. I think I may flash back to 4.4.4, I'm really tired of all this tinkering just to get things working correctly.

Nope. Didn't work. Is your phone a replacement phone by any chance? I called google they acknowledged a firmware bug. They will get back to me soon

No, mine is a launch device. Did they tell you any specifics?

Sensors work fine for me.

Half my drop-down menu settings are gone [Pic]

Hi

the spotify app.. nothing else

I can't understand how it can disappear without any update. Like Samsung sat a date in the system it should disappear on
Maybe it's there when we wake up tomorrow.

i am now having this problem, the phone rebooted itself which has been reported on the net by lots of people and after i downloaded an app i noticed that this mobile data icon has disappeared. i have about 32 gb of space left on my phone so i dont understand what has happened here.

happened to me to today , 920i not rooted, Saudi Arabia

So what was the point of OTA update? What's changed beside disappearing toggles?

I'm having the same issue here in Ireland since yesterday. Spoke with Samsung support and they said factory reset should fix it but I haven't done it yet
Has anyone tried a factory reset to see if it worked?

I've read that some people tested it and factory reset is not working as far as i know... If you have rooted your phone, there are some solutions exist. Otherwise, we have to wait for a fix.

Thanks for letting me know, saves me the time in doing so. I'm stock rom and no plans to root so may just wait for the patch/fix, cheers.

Go to

Same problem here in the Netherlands. Stock, not rooted.

Mobile Data & private mode toggles are gone, i am on stock rooted rom g920f, from Pakistan

Download Galaxy Tools and third from the bottom is an option that enables them all. Root required.

great tip, but due to the hardware problems I've had I rather not root (and yes I know that pingpongroot doesn't trigger kn0x).

Fingerprint sensor issue

Hi,
After updating to 7.0 nougat by official Europe update,
My fingerprint sensor stopped responding, when I'm trying to add new fingerprint it wouldn't let me even try, It shows a message (Attention: make sure that the home key is clean and dry, then try again) and then it goes back to the main lock screen settings menu.
I'm really desperate, already tried everything, plz help!
:crying:

Have you tried to factory reset or just flash android 7.0 with Odin. I would recommend wiping after installing an update like 7.0 anyway updating always causes bugs and issues for me.

I also just updated my SM-G935FD via OTA to Android version 7.0.
Since then, fingerprint scanner is not working. Like for OP, all tests fail under HwModuleTest.
I tried to remove all fingerprints, but it is impossible to add new fingerprints - the error message is "Make sure that the Home key is clean and dry, then try again." Obviously, the fingerprint sensor is as dry and clean as it was before the update (when it worked perfectly).
Since then I tried, unsuccessfully:
- removing old fingerprints and adding new fingerprints (does not work, cf. above)
- formatting cache partition
- performing a hardware reset
- flashed the stock firmware G935FXXU1DQB3 with Odin
Please advice, thanks.

If you have tried to flash stock firmware in Odin, I'm really not sure what the issue is, if it was just a glitch in the software it should probably have been fixed by a wipe and flash with Odin. If your phone is still under warranty I would bring it back into the Samsung shop or contact them over the internet to inquire about fixing it.

The same exact problem has happened to me too . I'm tired of unlocking with patterns
What should we do ?
This cannot be a hardware issue cuz phone was fine right before the update

Do you still have the issue ?

I have the same problem ???
What the way to fix this issue

I had that problem sometimes and in the end the main reason was really sweat on my fingers and dirt on the home button.
I know this doesn't sound like a solution, but it surprised me as well. Just try drying your fingers and clean the surface of the home button.

Hi There! I encountered the same issue earlier but then suddenly my fingerprint sensor works normally. The last thing I that I made changes to my phone was to reset the password of my samsung account. Not if there was a security breach that happened but after resetting the password, works fine for me. I suggest that you back up your phone's data before and after resetting your Samsung account.

I have this problem for 1 year, tried to change the password but didnt work.

IS someone still struggling with this problem ? Yesterday i upgraded to DevBase 6.0 Oreo newest build. But after the flashing process the fingerprint sensor act in a unusual manner. Sometimes i could unlock the phone sometimes it directly jumps to the pattern unlock screen. Any news about the problem ? I wiped cache/dalvik and i resetted my password of the samsung account - nothing helps.
Any help, ideas, links are highly appreciated
Cheers

V500N fingerprint scaner problem after update

Hi guys,
My V500N got an update yesterday and after it was installed fingerprint scanner stopped working to unlock the phone. It is still active and working correctly in all other cases, but as soon as the phone is locked I cannot use fingerprint.
Another clue to troubleshooting may be that I have installed ButtonMapper app to set Assistant button to enable a flashlight. And this function behaves the same.
Any ideas how to fix this?
