Hi guys,
I need help, my new one month old Tab S now no longer have the fingerprint sensor working.
It fell down small table where it flat out on the floor (wooden floor), with the LCD facing upward.
After the fall, it now no longer have the fingerprint function, so i have tu unlock using alternatives password.
I already tried re-boot, not helping at all.
decided to do factory reset since its a few month old, so no apps or data i really care to be deleted.( thought it would be a software glitch, since so many sensor giva data during the fall, i think so)
but still, when i tried to access the fingerprint manager, it shows
" An Error has occured with the fingerprint sensor, If this message appears repeatedly, restart your device"
I need the fingerprint sensor working to prevent the kids playing with my tablet.
Can anyone point me something that will help? or should i flash it to new firmware
Samsung Tab S 10.5 LTE SM-T805

Is there any damage to the screen? I don't know if flashing another firmware will help. If it's still looking good an everything, you can take it to Samsung and say it won't work. They should fix it under warranty..

There's no damage to the screen, it fall flat on its back.
it was a bit frustrating since it only fall at a height of 30 cm.
i was hoping this can be fix quick, since i started using it to do presentations to clients.
i try ask with Samsung first.
If your device has a built in dialler you can type in *#0*# to access the built in hardware test.
Also have you tried to re-register your fingerprint?
Hello,
Anyone else has this problem where the fingerprint scanner barely works (almost unusable) ? I tried many ways to enter the fingerprints but it registers like 1 in 10 tries...

same here. Samsung makes the worst finger print scanners.
thinking of 4 scan for same finger see if that helps.
Huawei makes the best finger print scanners

That is not normal, my A5 works 9 in 10 on the first try.
Not a single error in my A3
Mine is totally unusable... any idea?
Well, it seems that I'm not the only one with this problem. Hopefully it can be fixed with an update.
I have to say that my thumb skin is a bit damaged (from doing work on cars, around the house, etc.) but this was never a problem with my S7 Edge. I tried a different finger with healthy skin and it does work a lot better, but still not 100%, it seems to me that the A3 sensor has real issues.
same Problem with my girlfriends A3.
Fingerprint scannner works in 1 of 4 times if youre lucky sometimes doesn't work at all.
She has already made 3 scans with 1 finger but didn't really help
Maybe send it back for warrenty repairs if a factory reset won't work'? I'm sorry but fingerprint sensor should work fine.

To be honest, I don't think this is solvable via warranty work. I am not sending my almost new phone back just to receive a refurbished piece of thrash. I am putting my faith into a firmware update. The funny thing is, I really like the phone even with this problem, it is very fluid and has even better battery life than the S7 Edge.
So here is a workaround I have found, for those having the issue:
- Instead of using the tip of the finger when adding your fingerprint, use the area just below the tip. In the attached picture, use the area marked with green instead of the one marked with red. It will then work 100%, it's amazing how fast and accurate it is. It's just not very smart like the S7/S8 and other phones and it probably has issues when the skin is not 100% perfect or maybe with pronounced geometric distortions like it is the case when using the finger tip.
Hi folks, a workaround for me was disabling the keep screen turned off, became much more accurate after that
I've got similar problem with always on display. When I turned it off everithyng is fine
I am having similar issues with my phone. I have tried using all three stored fingerprints as just my thumb and I still have trouble getting it to unlock. I do have Always On Display turned on, and I don't really want to disable it as suggested in this thread because it's an awesome feature. Samsung should be able to something as easy as a fingerprint scanner right. Hopefully this is simply a software issue that is patched
hi guys
you lock phone with power key or with widget (like screen off)?
After having the same problem I started turning my thumb much more (even almost fully vertical) during the scanning process. Now it works fine. DHNL
hi actually solved the problem what i did is that factory reset the phone, i schedule a weekly restart, i clean my scanner and i assigned all 3 fingerprints on to the same finger and it worked
Hi folks,
I am experiencing the same issue. I found some relief using a different finger. I have registered three of my fingersprints. For some weird reason only one of the three fingers works acceptably good, the other two are successful very rarely. I therefore recommend you to try with a different finger or several of them to find out which one better works for you.
Good luck !
I can confirm there is indeed a problem with SAMSUNG A5 2017 fingerprint system. The recognition rate can be extremely low in some condition (around 10% positive, meaning almost unusable). This seems to be a software bug
Here is a turn around :
If you record your fingerprint with the screen "always on" function activated , then the recognition rate is extremely poor.
if you unactivate this function during recording process, then the rate is ok (higher than 90%), even if you reactivate the always on function after recoring session
I guess this could be solved by Samsung in the latest firmware A5 (2017) update.

you won.t need the workaround with AOD like on marshmallow
Hi
I'm searching for anyone else having the same problem as me and other people that i've seen in Lenovo Forums
I'm having different problems, but the most important for me is the proximity sensor, because once I answered a phone call, it makes impossible to hang up because the display turns black and it doesn´t "wakes" until the phone call has ended. The same problem with audios in whatsapp.
Another problem is that Moto Actions like turn on the flashlight with a shake, and open the camera with a twist doesn´t work anymore. Plus, the vibrator started to fail, having an unusual behavior until it just stopped.
And the device is not recognized correctly in any computer I've tried, it just appears as "unknown device", and the device doesn't show the options that use to appear when connected to a computer, it just says "charging".
I want to think that all of them are software problems, and not hardware problems, because they all started after the june 2019 update, and, as I said, there are other people having the same problems, and I think it would be a big coincidence if all of us have the same problems with our hardware.
If any of you have had the same problems, could you tell me if you could find a way to fix it? Or, anyone has any idea how could I solve, at least the proximity sensor problem, it would be better if the device don't turn off the screen anymore during phone calls.
I've tried reinstalling the drivers in 3 different pc's, and any of them worked, but when I tried with another device (Moto z2 force) they all worked. I've done factory reset three times, and one hard reset, with no changes. Could someone help me?
Thanks for reading.
Well, sound like... simply failing phone ? RMA ?

Do you think that? I've had this phone for a year and a half, and I've never had any issue, until the last update on june 2019.
Maybe is a coincidence and my phone started to fail just after the update, but to be sure, I want to know if there's someone else having the same issue, and maybe someone could fix it.
I've had these problems a few months ago too, but back then I was thinking it was related to a hardware problem cause I had to send my phone to fix the screen (broken glass) and after that I noticed that the moto actions wasn't working properly, as the flash light from the frontal camera and the most annoying of the problems, the proximity sensor that would stop working when I got a call or audios in whatsapp. All of these was solved a couple weeks ago tho, after I had to fix my screen again (yes, 2 times in 3 months, congrats), just days before the android pie was released, so I can't say exactly what fixed it
Hi everyone.
I have a note 10 + 256 go exynos from france.
SInce about last update one ui2.5, I have seen 3 issues which I think are related.
- AOD tap to show not working
- Double tap to wake not working
- When I remove the phone from the ear during a call the screen does not light up anymore whereas before yes.
I almost returned the phone in warranty a short time ago because my screen only registered two fingers,a few days later I received an update that fixed this problem.
For these 3 problems I tried 3 things :
- Update touch screen firmware via *#2663#
- Factory reset
- Reflash the stock firmware with odin and frija
I also have another problem a few times a day the screen freezes, I have to lock unlock the screen and it works again..
Do you think it's a software problem or a hardware problem (damaged screen, damaged sensor or other)?
Please help me thanks.
Lol, firmware and/or software; maybe a settings or permissions issue as there are many. Hardware rarely fails unless it receives severe abuse. You can perform some of the builtin hardware tests just to be sure.
Try using the factory load if the apk in question has been updated or wait for an update that fixes it. Be sure to check the Gallaxy Store for updates.
I'm still running on Pie because it's fast, stable and functional. No scope storage that I don't want or need.
Once you get an OS optimized and running well there's little advantage to upgrading many times unless the new OS is really worth it.
Many times it's not... I'm still running W7 too.
You invariably end up with new issues, hunting down all new glitches and worse, since it's new there not many online solutions.
Thank you for your help.
I mentioned the 3 main methods of fix but of course before that I had already tried the basic things like clearing the system cache, checking the permissions of the AOD application as well as deleting this data.
I also checked the sensors with * # 0 * # but I did not find anything problematic
I even tried to flash the november update with odin and frija and I got a soft brick, so I don't even dare to try a downgrade firmware, I don't have the knowledge, I read that I had to keep the same bootloader and I get lost in the different firmwares
Those are all system apks that run in the background.
Is Android System configured correctly?
Try clearing it's data and of course the system cache.
A hard reboot as well.
It's interesting you lost the proximity sensor.
Thanks.
Yes I have cleared the system cache several times, android system too. I even did a hard reset. I think more and more of a hardware problem, because all these functions are linked to the fact that the screen does not wake up by touch when it is turned off.
the proximity sensor still works at least partially because it flashes well during a call and turns off the screen when I put the phone to my ear, but no wake up when I take it off my ear.

If it happened after the firmware update... it's in the firmware or software.
Bad firmware can sometimes blowout a cpu but doubt it damaged the hardware controlling just that one feature of the touchscreen.
If that was the case the touchscreen wouldn't work at all.
Maybe the firmware is ok but got corrupted during the download or flash.
A defective memory module could corrupt the load but again that rarely happens.
So back to the firmware/software/settings...
Maybe someone here has seen this before or has a better idea to sort it out.
Honestly I'm not sure it's exactly after an update.
It's just that it's not functions that I use very often. I don't call a lot of people and most of the time I use very little Aod and double tap2wake.
Usually when I grab my phone to use it I unlock it directly with the fingerprint.
when i mentioned the problem where my screen only recognized two fingers at this time , aod and dt2w were already weird as it only worked on the top half of the screen not on the bottom half ..the update solved the problem for the 2 fingers but not for the fact that aod and dt2w only works on the upper half.
Now for some time aod and dt2w no longer work at all no matter where I touch the screen.
I want to clarify that I use a screen protector with loca glue but that it is from the beginning and that it has never been a problem before.
I know this is a weird problem thanks for your patience
I never use a lock screen or the fingerprint sensor.
There may be a conflict because that... disable and see if that helps.
The screen could goof up the proximity sensor. Probably not but next time it's off, check it out.
No worries; these devices fascinate me.
Hope you sort it out; eventually one usually does

2x post
when i did the factory reset it was the first thing i tried before even resetting a password but it didn't work anyway.
For the screen protector I use the same brand from the beginning and it has never caused me a problem of this kind, but maybe this one is defective ..
I would have to remove it to try but I have lazy to change it again because I had to change it twice in a little while.
Hoping that by dint of applying the loca glue I haven't damaged anything.
Thanks
Nah the glue didn't hurt anything; it's well sealed.
The tap on AOD I never use but I double tap to turn the screen on/off. If I lost that I be witch hunting.
Try increasing the touch sensitivity if you haven't already... and make sure no other apps have accessibility permissions that could conflict. Same for device administrator permissions.
Try it in safe mode as well.
Hi guys,
Lately I've noticed that my fingerprint sensor does not work properly anymore.
Not sure if it's a hardware or software issue?
Though, the test HW for Fingerprint Sensor from Smart Doctor app reports Good status during all tests.
The behavior is strange and not consistent, most of the times it will work fine but from time to time I cannot unlock/wake the phone with the fingerprint sensor, it's not like the fingerprint is not recognized, it's more like putting the finger on the sensor and nothing happens (it doesn't vibrate like is reading it or not) . Not sure if is related to the phone being in standby for longer period, or I don't know ...
I'm more inclined to believe it's a software issue, and seems to have occurred lately after last update to Android 10 (v30f-EUR-xx, phone type LM-G710EM).
I've tried may method, deleting the finger prints and add them again , even did a factory reset but the issue seems to come back.
Do you guys have such issue?
Any idea how to diagnose this further?

Make sure your battery isn't swollen. A swollen battery will take out the fingerprint sensor first because it's right on top of the connection.
Hmm, interesting, from the outside I can't feel any difference, the back seem flat.
Exactly the same problem here. But if I check the sensor while it is not working I get a "sensor not respondong error".
Did you solve somehow?
Thank you
