Fingerprint Sensor Not Working - Samsung Galaxy S8 Questions and Answers

Hi guys, i have a big problem and i beg you guys to please help me out. I'm using s8 950F variant. The fingerprint sensor is not working. It shows "An error has occurred with the fingerprint sensor, if this message apears repeatedly please restart". I did everything i could. I dialed *#0*# and tried to test fingerprint sensor but i showed "fingerprint version: null" then i thought i should clear fingerprint app data. I went into settings>apps>system apps. But the offical fingerprint app was not found. Also tried safe mode.
Conclusion::::::
*#0*# test shows fingerprint version: null and the fingerprint app has also disappeared.

Same issue here.
Worked fine, then 5 minutes after same issue.
Did HArd reset but still the same thing.
Any help?

Dude i solved it.
Turned the phone Off
Then i "filliped" on the sensor.
Pushed with my thumbs at the approximative localisation where the sensor is connected.
Turned on the phone and VoilĂ

I'd like to know more about this. What do you mean?

Sorry my english is not good.
When i say "fillip" i mean i hit the sensor with my finger.
Then i pressed the back of the phone with my thumbs a little hard where the sensor is approximatively connected.
And it worked.
I think "version null" is returned by the phone when it cannot find any sensor plugged. So it might be broken or unplugged.

Worked for me as well ?

Nice.
So the problem is physical and is present on many devices.

Fixed!!
Thanks so much for the tip! I have been searching for hours for a solution. Tried all of the tips on other sites. All trying to say it was a software issue. I am so glad I ran across this post!

I'm happy for you !
Maybe this post need to be on top so every people with that problem can find the solution.

9100 3G bricked, or something worse?

Hi, I'm a Newbie as You can see I will try to describe my problem. I have a qtek 9100, and I (being so dummy) flashed a wrong hard spl from another phone, (I don't know, from what phone, I just surfed google) and now the phone doesn't do anything, I tried to cold reset it but it didn't worked, I tried to push all the buttons and power it on, that didn't worked too can You suggest me something? its a 3G model, if You need more info, just ask, I will try to answer
could Anybody Help me?
Please
...heh....
Please provide more info about your phone. What's the exact model. If you look under the battery of your phone you can see the model.
I think that you mistaken something. There is not any 9100 3G model. At your phone is there a second camera?-
sorry I mixed up sthg.
it's a T-Mobile phone, it was CID-Unlocked, and i don't know exactly, but under the battery it's written that it's wiza200
Take a look at this guide & follow the steps one by one. I hope that this will work.
If this don't work & you are sure your device is CID unlocked you can try flashing T-mobile 2.26 (with a little search you will find it ).
T-mobile have saved my a-s a lot of times .-
sorry, but that didn't helped for me.
the phone is not responding to anything, it is like a brick
when i press the camera button and the on/off button, nothing happens, no boot loader screen at all

Are you sure your battery is not completely dead? Do you have the original 1.0A charger?
Yes, I'm sure about the Battery
I Don't have the original charger, but I test the Battery with another phone, and it works fine..
I flashed a Wrong SPL.. isn't that the problem? and I don't know how to bring it back
I don't have time to search it but you can search for ''jump start'' or ''kick start''. It is a way to start your Wizard with a similar problem as yours. Simply you connect a 9v or 12v (I don't remember) to your battery & then you put it in your phone & it starts.
As you can see I can't remember exactly what you must do. Search it. The exact instructions are in the forum .-
Sorry, That didn't worked for me too.
The phone is Dead..
and I need to Bring It Back to Life..
You still haven't provided enough specifics about what happened and is happening to your device. Do any lights come on? What specific rom did you flash it with? You are going to have to search through the past discussions. Don't lose heart - others have gone through a similar ordeal.
Well, at least you can still sell it for parts...
I'm sorry to hear about your mistake, but that's why there are so many warnings to read and read more before flashing.

So that's it?
It's a brick?
The light does shine, but just after many random pushes of on/off button, reset and camera button. sometimes ir shines for a long time, and sometimes for just a second.
and i don't remember which rom did I flashed..
it was a long time ago..
H-Jtag wouldn't help?

Phone never sleeps

Help me please.
Until today everything was fine, than, I can't put the phone to sleep.
When I press the end key it comes black and after 1 second turns on again at the lockscreen. I can't put it into sleep mode with the screen off.
Neither in battery or plugged in charger.
I dis a hard reset, installed new ROM (Artemis) and new radio but nothing can solve the problem.
Do someone know what's happening ?
Sorry about my english.
Thank you all.
Additional information
When i conect and disconect the power cable it returns to normal, everything ok until next boot. If i reboot, the problems begins again.
Probably the last option but a hard reset will likely cure it.

Try this

No, after the hard reset nothing was installed.
The problem still exists even when I remove the sim and the SD.
But when I conect the power cabe (for a second) evererything is back to normal.
sounds like a hardware problem then.

[Guide]For people with white screen

If your xperia play (Doesn't matter which model, it affects all plays) is getting this white screen here:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

}
The problem that you are facing is a busted flex cable. I'm posting this thread because I have seen in the past week at least 5 people ask what the white screen is, and how to fix it. Here is a video on how to take apart your play: http://www.youtube.com/watch?v=-3n5ZfkqhzE and here is a link to where you can buy a new flex cable: http://www.ebay.com/itm/Flex-Cable-Ribbon-Connector-for-SONY-ERICSSON-XPERIA-PLAY-Z1-Z1i-R800-/180869752159?pt=LH_DefaultDomain_0&hash=item2a1cad655f#ht_1547wt_1185
The only way you can avoid the flex cable damage is to keep from sliding your gamepad in and out all the time. So basically, just try to do it if you are actually going to be playing a game, not just something you do because you are bored.
I hope this helps anyone with that problem!
Thanks. Does this mean sliding up slowly as well yeah ?

Basically It's every time it slides. Just don't sit there rapidly opening and closing it.

I have that problem. It still works perfectly when I open the gamepad, so I don't care.

I'd order a new one soon, because eventually it breaks with it open too.
i have a different problem
first my screen would come on but the phone was on and working etc
but the screen stayed black
if i kept pressing power on button or the hardware keys it would come back on sometimes
or if i restarted the phone
but now the screen wont come on at all, i power the fone on and it vibrates
and then it vibrates again and power buttons goes blue for a short time i think to signal that doom kernel has loaded and that u can go to recovery
but that it.
phone is dead
Wow, this is a huge problem. Is this happening to a lot of launch-buyers?
I don't know what your problem is...It might be your LCD
Ah, I have this, but its only partially down the left side of the screen, about 20px

Thank you for the video, I just push the conection and works.
Sorry for my English
Sony repaired my flex cable for free, although i unlocked my bootloader with a key from their website. So if you still have warranty on your device you don't have to fix it your self and lose your warranty completely.

You're on stock Cyanogen OS. That sounds good. You could solve your problem entering manual testing mode.
Type *#*#1111#*#* then go to Manual Test - G Sensor Calibration, put your phone on a plane surface (plane to all directions!) and press the only existing button with chinese signs. After calibration, press pass and go back to leave Engineer Mode.
I can't repair my Zuk because I replaced recovery and also installed Cyanogenmod, and this code don't work for me.
I hope hear from you good news. And if you have any question here I am.
Good luck.

Now give me back the favour:
Just tell me how your Zuk got into this problem. Did you hit the phone. Some kind of crash.
Mine started to get crazy after a snowboarding fail.

I don't know exactly but I think come from the factory, I'm sure it never crashed.
my g sensor is way off too, with alot of drift in cardboard apps etc. i entered engineer mode as above and done the calibration, i get this fail message " test failed, please find the soft engineer"
it wont give me the option to press pass.
any idea on how to fix this??????
Just update your phone!
Before the update it didnt work either!
But since I update it to the newest fw, it all worked as it should!

Ow! That looks like one very unhappy Nook
The screen will not change unless there is an input to change it. So if you disconnect the battery and just reconnect it, maybe nothing will change? Did you try turning it off/on? (I'm sure you probably did). Can you connect via USB? If you have ADB access you could issue a reboot command and see what happens.
It seems unlikely that lightly wiping the screen could damage it--assuming that the screen was not "active" when you were cleaning it.

I was very suprised myself that something like this happend without dropping the device or anything more serious.
I have tried turning it off and off, it works perfectly (usb connection, all buttons) apart from this screen issue.
Going to look up how to issue that reboot and check in soon.
Thanks for your response !

The other thing that occurred to me is you might try the clear screen app from the PlayStore:
https://play.google.com/store/apps/details?id=com.lggfc.nookclearscreen
If you have a way to install that and can run it, it may show whether the screen is responding to refresh commands.
Update.
Cant find any instructions on how to reboot device through usb/pc. Cant even unregister it as half of the screen is just covered in static image.
Any suggestions?

Um...well I guess even if you had SearchMarket on your NST you would not be able to make any sense of it on that screen. Then again, if I post the apk file and you install it via ADB I don't see how you will make it work.
Never mind. Dumb idea
