Finger print reader doesn't work - Sprint Samsung Galaxy S6

Anyone's reader doesn't work sometime?
I've had much trouble with it not working and actually promoting many errors.
After many times re-registering my prints, I got it to work well. Now since yesterday morning, the reader just flat out doesn't know a finger is placed. No vibrate, just screen times out. Sometimes it'll vibrate once no match then fail to notice my finger thereafter.
Anyone else have these problems?

I had this exact issue last friday. After a full restore the fingerprint reader still wouldn't register any touches. I took it to the sprint store and they gave me a new S6. There are some other threads in the T-mo forum where people are experiencing the same issue.

Thanks for the info. I've been trying to get past it, avoid exchanging. But just might...

Try a complete shutdown. Boot into recovery and wipe cache then restart.

Didn't work. I know what's going on partially. There is a huge delay in registering the finger, why? Idk.
You can validate on this screen. Takes 5 secs to notice and 3 to respond to taking finger off

Ok so trying to figure out what's wrong, I wanted to reboot the finger print service, thinking there was a process running for it. Sure enough I found it. I stopped it, and now it is running as efficient as it was before. Pretty awesome.

Nice to see you here hayabusa. We seem to have the same tastes in phones! Anyway, I had similar issues and so have others. This may be turning into a common issue! You can follow the link I posted in this thread for others having this issue.

I returned my first s6 on day 13 and got a new device with basically no hassles.

Definitely the LG G3 I skipped a gen haha
No more issues other than this, that's why I didn't want to give it up. Now they do need to do an update for ram optimizations cause it currently sucks, can't multitask with apps closing out.

having the same problem with S6 Edge

Same issue here. Was at work showing a customer mine... fingerprint scanner failed to recognize any of my fingers.
Backup Password would not open my phone either. After entering my Google information multiple times, I had to resort to a full device reset in order to have a working device.
Not exactly what I was expecting from this. I had no problems whatsoever up until that point. The device simply went to sleep and the fingerprint scanner stopped working at all.
After searching it seems to be a bit more widespread than anticipated. All carriers are seeing the issue.

Damn. It's random when it works or not

Here is video I recorded of the issue. Clearly you can see how it doesn't work as intended delayed response.

The reader is defective. It senses my finger on the button well after I have taken it off. Notice it says "lift my finger.." I can no longer blaze through it as when it did work.

I don't think you quite understand how it's supposed to work. You want to read as much of your thumb as possible, not just keep placing it in the same spot. That means placing it in different positions and different ways. I read most of my thumb and now It unlocks in a second from any angle. But yes, the initial reading takes a long time.

I understand completely how it works. The issue is not my angle. For demo, I recorded my print this way and that's fine. But you fail to see the actual issue at hand. The reader is defective.

Maybe you're experiencing the memory leak to cause that sort of behavior. After the first fingerprint reading, mine always had timing issues, and it turns out it was fixed after I deleted the fingerprints and rebooted my phone.

Yeah I know I have memory leak for sure. My home screen reloads often, I have to close out all apps then it'll be fine for a little bit. I wiped cache from recovery, reboot etc. The reader remains unusable still. Seems like this isn't widespread but still affects some of us users, not to mention the ones that don't frequent XDA. I understand 5.1.1 aims to fix memory leak. Sucks but still the best phone I ever had.

Just updating that I did a factory reset, and has cured my ailing print reader issue.

I had a similar issue its been random, i have been unable to narrow it down, so due to frustration I have stopped using it I will attempt to reset it and do it again. I love the feature when my nieces try to take my phone and they cant get in.

Jellybean problems

First off, if this has already been done then sorry im obviously blind, if not then i think its a good place to post any jellybean related problems and fixes that people have discovered.
so here goes, i updated from the ota on thursday the 12th of july i had a totally stock yakju device with the build number imm761 (JRO03c after update)
problems i have found so far are
1.after every reboot the, screen stay awake during charging option is ticked in developer settings
2.the google now command of navigate me home will take you to a random address near your home even after setting home address in navigation app and in latitude (as far as i can tell this is only happening outside the us)
3.lock screen will only ever say 99% charged even when in battery settings it reports fully charged
i have not found a fix for any of these issues nor do i know if they are just problems on my device (barring the google now navigate me home command)
so if anyone could report if they have the same issues or have found fixes please post here.
thanks
Now has stopped listening for the keyword "Google". After a couple days with out reboot it seems that Now no longer responds when I say Google. I have to hit the mic button. A reboot would fix it... but a weird bug to say the least.

I have a big problem since I did update to Jellybean
My phone charge itself, without it connected to AC power or PC.
And when I want to charge the power source does not load.
Last night I put in charge and not loaded than when we closed and I pressed power button + down button.
and camera, how do I set resolution? I make pictures. PNG 720x1280 on ICS I could change the resolution,
Jealybean sucks

You have reached the Holy Grail of getting power to a mobile device—this is not a problem/consider yourself very lucky.
I do not think this is too good for battery life, and actually not charge only indicate that charge
Probably hardware issue.

That's a pretty common Samsung issue, usb port dirty, faulty.
Either clean it or go to repair.

2) I'm in the UK and don't have this bug, ensure your home address is set correctly on maps.google.com and that when you click it the pointer is showing your house only and not a generic area.
3) Again, not experienced this. My lockscreen shows 'Charged' when at 100%
Sorry fella
I can't speak to the first two problems but I can confirm that it only charges to 99%. It's been that way on every ROM I've used since stock 4.0 so now I just say 'close enough'.

Battery stats is what's responsible for indicating charge to my knowledge. Try wiping battery stats in CWM

I've seen this happen before on a brand new HTC X One, happened after about 4 days of being used. We let the phone fully run down and then just changed it, didn't come back again.

LG G4 screen turning itself on after timeout/lock

I've had the G4 since it was launched and until now been very pleased. A couple of days ago it started to turn the screen on by itself every time it timed out or I pressed the lock button... Unless it's plugged into a charger.
I've tried pulling the battery and uninstalling any recent apps I'd installed but to no avail.
Annoyingly, by the time I got myself to carphone warehouse to get it sorted I was just outside my 28 days.
Seen a lot of people having issues with the screen but can't find anyone having this exact problem. Anybody experiencing similar? Any thoughts? Cheers.

Guess there's not a lot of people suffering the same issue... Noticed something odd today with the battery. Never seen it drain this fast before, is there any way the screen issue could be related to the battery? It would kinda corroborate that the phone acts totally normal when it's charging... Trying to find someone else with this phone to try swapping batteries is... Difficult.

Do you have a screen protector on? If you do, is it possibly covering the light/prox sensor?
Nope, no protector, and I often manually cover the proximity sensor to demonstrate more easily what the phone's doing. Screen times out straight away and them comes back on just as quickly.
Same issue here
Sorry to drag up a thread but ive been having this issue from day 1 and its driving me MAAAAD! Press the lock screen button, the second the screen turns off it comes back on and its on the lock screen (like it would if i used the power button to unlock it)
I turned on "show touch screen touches " in developer options to see if the screen protector was touching anything but its not As far as i can tell it looks like the lock screen sensor might be dicky/weak from the factory? Major sads considering its the button I use on a hourly basis!
Any help or ideas greatly appreciated, i dont really fancy taking it back after 4 weeks to have it sent of for months to be looked at/repaired
H815P suffering the same but mine is randomly. I hardly ever notice but sometimes I just look at the phone and the screen is on.
Also same issue it s wake up randomly, screen is on suddenly and turn off, any solution?

That is the problem.
if yo use the auto hibernate in greenify, it wakes up the phone, turns on the screen than after hibernation turns off the screen. That is why I use only the manual hibernation. On unrooted phone it cause more battery drain than running the pr in the background

yes, on rotted phone the grennify is working as system app in the background and makes the hibernation without waking up the phone and screen + on rooted phone you can hybernate system apps too.

Hi there! thank you for the post thread! I recently got changed of my LG G4 motherboard by LG as I had another problem, and since I got back my phone it keeps turning the screen on-off randomly. I tried to change the auto-screen-off setting you described (hibernation) but the screen keeps turn on and off itself every 15secs! I even changed the phone settings to no background processing at all but same thing on and off again.. I did several factory resets, even tried not to install any app or even update the basics ones and keeps doing it randomly. I dont know what to do here please any help would be appreciated :S:crying:

Hey its the sensors next the the front camera that is causing this i had this look reply typed and it just disappeared but long story short i noticed it didnt down it when the phone was facedown so i tried covering the sensors next to the front camera and it didnt do it at this point it could just be a program error or hardware problem idk how it turn off the sensors and it may look tacky but use something to cover the sensors and you should be fine im not 100% sure this is the problem im still testing but so far it works
Try disabling knock to wake feature. I recently noticed that I could tap anywhere and then again somewhere else, minutes later, and the screen would turn on. It was so sensitive that sometimes it would wake by just blowing on the screen.
To get to this setting, I created an activity widget using Nova launcher. (It's under the Settings -> Knock settings).
You can also use Better Battery Stats or Amplify to see what's keeping your screen on
fixed mine

Fingerprint scanner randomly not working

I'm just trying to narrow down why randomly the fingerprint scanner does not wake the phone. It might happen once a day or not for a couple of days, but it seems to always come back. Not a huge deal since the power button will always work, but it is disconcerting when it happens. I'm not using any power widget or lock program although I do use Nova Launcher Pro. Does this happen to anyone else and if so have you narrowed it down?
Mine always wakes my phone, although every now and then it doesn't recognize my print. However, I believe it's because of how my finger lays on the sensor so I think it's user error in my case.
I've registered 4 prints, 2 from each index finger and all in different positions on the sensor to get the least reading errors.
Are you saying that you get no vibration as in it doesn't even register at times therefore you HAVE to use the power button to wake it?
I use nova pro too.

Yes exactly, no vibration. I've had it where it vibrates and doesn't unlock because my fingers are slightly wet or something. This is like it doesn't even know my finger is on the sensor. Power button unlocks and then it works again. Last time I said ok I'm not unlocking with the power button I'm gonna get this to work. Nope, had to power button it on after a minute or so of trying. As I said, it's not that big a deal and only happens once in a while. Glad it's not Nova though. Kernel dev said it's not the kernel , I'm using Elemental X. I might try going back to the stock kernel just to test it out. Problem is that I can't reproduce it.

I get this occasionally when charging but that occurred on stock everything, can't say I've noticed it in any other capacity. Are you using smart lock or an app to lock your screen?
Edit: I should read your post before replying, disregard my app question. Still asking about smart lock though.

And I meant to include the "big" question in my original reply. Big being "what mods are you using"
Best way to trial and error issues as you well know? I'd test it on all stock (for a day or 2) and see what that gets you then you can narrow down to if it's the kernel or not. I'm not a kernel dev, but an educated guess would point to that imo

No mods.. well let me rephrase that. I have a bunch of programs running naturally, but the only "mod" I have is Cataclysm and systemless root along with Elemental X kernel. Cataclysm is considered a mod these days as it's just an overlay on stock 6.01. I know I'd have to go full stock to test for a few days but I'm so so trying to avoid that as I'm sure you know. Thanks for all the input guys, I know this can't just be me right? Hey wait a sec.. I do have a BT smart band unlock running. I'm going to take that off and see if that makes a difference. Maybe that is interfering with the fingerprint requirement.
Edit..nope not it. Gonna run stock kernel next.
The exact same thing is happening to me. Same symptoms but I am on fully stock. I'm also using nova pro. Been searching around for an answer but haven't found anything.

Too many people on Nova Pro for it to be an undocumented issue. I know it's been said that it is not the kernel, however, yesterday morning I flashed this one http://forum.xda-developers.com/nexus-5x/orig-development/jolla-kernelbullhead-t3271530 and I've not had the issue since. I usually have it at least once / day and none so far. That doesn't mean it's not going to happen in 5 minutes though. I went with stock kernel values if you're rooted and feel like giving it a try.
I was having this issue randomly when running custom hotplugging. Currently no issues with default cpu hotplug settings and ElementalX.
For me I have a case on my 5x. There are two cutouts - one for fingerprint sensor and one for camera. They're both about the same size. Every once in awhile I find myself reaching for the camera instead of the fingerprint sensor. When I first got the phone I thought my fingerprint wasn't working at times. Turns out I was just putting my finger on the camera instead of the fingerprint sensor. Any chance this is what's going on?

Don't make me question my own sanity! hehe. I did the same thing at the outset but quickly realized my error. This is not what happens here, however. I even put it back in my pocket once to make sure it wasn't some aberration. It just wouldn't recognize there was even a finger there. Almost thought the phone had shut down but power button got it working again. Haven't had the issue in well over a day now with this kernel but I'm not sure that's what it is.

This has happened to me twice. Both times while charging. Has not happened any other time. (stock everything/not rooted)

Happened to me not charging, rooted with custom kernel. So it's across the board hit or miss. I have a feeling it will be fixed in an update or OTA. Not a deal breaker just odd is all. Oh well, if we didn't have a power button it would be major.
After 3 years of usage my Nexus 5X fingerprint scanner stopped working at all and i can't do anything about it apparently. The issues started when i sent the phone to LG to fix the bootloop

LineageOS 7.1.1 G900T randome blue black screen

I have a G900T running Lineage OS 7.1.1 latest build. When I am out and want to use my phone I keep getting this screen, and I want to know how can I fix it. I keep having to remove my battery and reboot to clear it up until it happens again. Any ideas?
https://www.dropbox.com/s/eeir3ey2u6sy9gl/2017-04-08%2014.25.56.png?dl=0
I am just wondering if I am the only one having this issue?

Are you saying it doesn't happen at home? Maybe something to do with location or data? Or is it just not waking up properly?
(When I first instilled 7.1.1 I had a black screen from boot but I had the notification bar showing and other layers like power menu would show, is your whole screen black)

That is exactly what I am saying. Sometimes I just look to see the time. When I press the power button to wake it up when it does happen which is quite a bit and I never know when.
When it does happen it will wake on that screen and sometimes I will see the lock screen for a second then it goes to that. I need to then remove the battery and reboot the phone.
This mostly seems to happen when I am out. Usually when I need to do something at the worst time.
Then if I am looking something up for someone, I need to be telling the person holdup while I reboot my phone.

strange that you get that screen, otherwise it sounds a bit like people who have lock screen issue & have to reboot to get phone working again. Related to display &/or touch problem I think
This is often caused by dropping their phone, have you? Knocking it on different edges sometimes fixes it, but you need to be careful not to break screen! Though better solution probably is to open it and reseat pcb, screen connectors etc.
Also using magnetic phone covers can do this, I think.
Else can't think of anything apart from software (affecting your phone only it seems) maybe clear data on lock screen service app .... maybe clear any profiles you are using ...... else the dreaded factory reset or clean flash, but I'm sure you know that and don't want to do it!

Yeah this only started happening after installing Lineage OS 7.1. I will try another lock screen. Hopefully that will take care of it. You are right I don't want to do a reset.

Question Fold 3 having micro stutters for no apparent reason.

I was able to upgrade my fold 2 to fold 3 in September and have been regularly using the fold 3 as my personal device.
However recently I have noticed the fold 3 stuttering and having frame drops while doing simple tasks like changing apps or opening and closing apps like YouTube or gallery.
The small stutters became more apparent after using the s22 ultra for a few days alongside it. I have not faced this issue with the fold 2.
Anyone else facing such an issue and advice on how to fix it?
I have done all the cleanup optimization etc and even checked the battery for any unusual drain etc. So far I'm not sure what's causing it to have these micro hangups.
F926B model ui4.0 latest February update installed
Clear system cache.
Disable all power management.
Try is safe mode if it persists to rule out a 3rd party app.
I had a similar issue recently. I tried using the phone for a while in safe mode, but the same results, micro-stutters and sometimes complete freeze and black screen, which led me to reboot the phone. So I had to factory reset it and start from zero. Everything is smooth so far, but tbh, I think I went too far, first you should try what @blackhawk suggests.

One UI version: 4.0

Poorly written 3rd party apps can cause a lot of trouble, even boot loops. Any sign of system instability should be taken very seriously as it's the only warning you may get. Lol, been there, done that. 2 back to back boot loops until I recognized the troublemaker
If any major OTA firmware upgrades have been done it's best practice to do a factory reset. Otherwise it's best to find the root cause to prevent it from happening again.
Malware is always a possibility when abnormal behavior persists and can't be identified. Usually it's installed or downloaded by the user. If malware is known to be present and can't be completely eliminated in an hour or two, factory reset.
One of the best way to ID problems is to spot them as soon as they start and to be able to associated them with something you installed, changed or downloaded. Otherwise they tend to fade into the blur.

I have not done system cache clearing since my note 4 and frankly I had completely forgotten about it.
So far it seems to have fixed the issue.
Thanks
Just FYI for everyone you need to connect the fold 3 with a USB C to a Mac or PC before powering on (Power button and volume up button) for it to open in recovery mode, doesn't seem to work (atleast for me) otherwise.

Yay! You're welcome.
It will solve many strange glitches. Completely safe so it's worth a shot. Otherwise I do it about once a month as part of routine maintenance.
Hey whats up guys ok
So I had very wierd situation where I have slow scrolling micro sttuters that are driving me insane throughout the entire almost all apps ecept the system settings on the cover screen and main screen
I uplaoded a video
Whats I did find is that it doesnt have this problem at with the Spen how can this be seriously and my GF has a S22 Ultra and of course she doesnt have this problem
I have also tested the Fold 4 in store and doesnt have this problem either.
I have also done what Blackhawk suggested still same bull**** problem
Please let me know as there has to be some type of fix again since it doesnt do it with the Spen
Thanks Here is the video I uploaded to Reddit

The spen thing is odd.
Try in safe mode to rule out a 3rd party app as the cause. Is global power management disabled?
Try turning off all animations in Developer options or Visibility enhancements.

You'll likely eventually track it down or find a work around (other than the spen). Play with it.

Worked just fine for me without plugging the phone in when I tried clearing the cache recently (didn't fix the problem I was having). You have to hold and then release the two buttons at the same time when you reach the logo screen. You can Google for instructions.

It happens in safe mode too, right?
Is it running warm at near idle ie excess battery consumption?
Was it always like this or did it recently start?
Try temporarily turning off Developer options.
Try changing refresh rate settings.

Yes It does
No running normal and no strange battery drain for anything
The problem was that before Andriod 13 I was having sttutering through out the entire UI very bad
Finally Andriod 13 fixed all of that but I had never noticed micro sttuters as I had insane sttutering everywhere
How would Dev options have anything to do
Becuse the minute I Use the Spen it never does it
Do you have Fold 3 can are seeing any of these issues
I'm running 2 N10+'s; both still on the factory loaded firmware, 9/10. Gorgeous, fast, reliable work horses. No way I'm upgrading firmware or hardware any time soon. Both Samsung and Google Android dead ended out over 3 years ago as far as I'm concerned.
You sure the micro stutters aren't it dropping the refresh rate down? Try different fixed rates.
Cycling Developer options sometimes resolves issues.
Be better to find the root cause rather than factory reset as it may reoccur. However if a factory reset doesn't solve it... it's either a default setting issue, firmware or hardware.

I see I though you had a F3
Well Iam not doing a factory reset that never fixes anything and makes you start from scratch which I cant do now
I try and turn off Dev options
Yes I ran the refresh rate and says 120 solid during the micro sttuters which is bull****
Again what makee no sense is that it wont do it with the Spen
You did clear the system cache from the recovery menu, right?
Try a lower refresh rate. Again disable all animations.
It will make sense once you find the cause. Be glad it's giving you a clue.
If it's a fault in the firmware or hardware you want to find out sooner than latter. Justification for doing a factory reset.

Yes I did that as well no change and more crazy is that with that setting on you get crazy sttutering in the setting sections and UI how js that possible and I only have my front screen protector no inner screen protector as mine started to crease and go bad 1 month ago so I removed it

The factory screen protector? If so replace it as those displays are expensive. If the inner protector cracks it will eventually destroy the display if not replaced. I'm out of ideas, sorry.
