Fingerprint sensor is fu....g dead - Galaxy S6 Edge+ Q&A, Help & Troubleshooting

Hi guys
It's a couple of days that my fingerprint sensor won't work at all.
When I tap on fingerprints in settings it shows the message of the first attached pic.
Obviously I've tried to restart the device, shut it down and booting lots of times. It used to work for a while, but then the message will reappear.
Dialing *#0*# and going to the sensor sections shows just "null" as it doesn't even exist.
I've also tried a factory reset. Didn't worked.
Tried to wipe data files and cache from app manager. Nothing
Any ideas?
I still have the warranty valid, but there's a mark on the bottom of the device caused by falling. Will they accept warranty anyway?
Thanks to all

They probably will repair under warranty, you've got EU consumer laws on your side, if you've had it less than 6 months it'd be more in your favour generally.

[Q] My phone is junked - unable to drag-up the LockScreen in 1, 2, 3 ... attempts

I have an HTC surround. I am having a problem sliding up the lock-screen. It takes number of attempts to slide up the screen. Sometimes it results in missing the incoming call. It appears to me there is a mechanism (an observer) which negates the touch event if the phone is in pocket while the phone is locked. In my case, even when I am sliding the lock-screen up with my finger, the observer is negating the action and the lock-screen comes back from 20% slide-up. Other than that, the touch-screen is working perfectly fine.
Q:
Is it a software or hardware issue?
Is there a workaround (something like hacking into the ROM and playing with the drag sensitivity)?
Should I dump it and consider myself "done with the WP7"?
P.S.
1. I got this unlocked ATT phone from US and now using it in middle-east.
2. (Not sure but) I have heard that ATT only return the phones with monthly contract.
3. The problem started after 12 days of first use.
4. I tried hard and soft reset, with/without nodo and latest updates. But it’s still the same.
It sounds most likely like it is just an inconsistent/bad touch panel on the hardware. You could attempt to replace it yourself by purchasing another one on eBay, but I doubt that any software fix would be able to fix this behaviour. I have a Samsung Focus WP7 and this never happens, the only time the lock screen comes back down is if you lift your finger before getting to the top. So my best guess is that the touch screen just cuts out before you can get the phone unlocked. Sorry....
I have the same issue. Does anyone have a solution, please!!. I'm in another country, so I can't return it. Have to fix it!
same issue here.
Do you have anyone in the US that you could send it back through? You might also try contacting HTC directly. I believe the phone has a 1 yr warranty on it. At least that's what Asurion told me when they sent me one as a replacement for my old Tilt 2.
My Phone have same problem, i install NO-DO next install PreMango but not helped.
I have no such issue with my sourrond, with mango 7720 and speech for phone accessibility turn on you only have to slide less than a inch to unlock screen...
A possible answer
After some researching i found this in one of the forums of HTC
Display Not Working on the HTC Surround
Black/Blank Screen
Verify that the battery is properly installed in the device.
Attempt to power the device on by pressing and holding the power button for 3 seconds.
If the device won’t power on (also indicated by no LED’s) attempt to charge the device. If there is no response from the device when attached to a charger and power source, treat the issue as a Power/charging issue.
If the device will or is powered on:
Verify that the device is not in hibernate mode by pressing the Power Button once.
Once you have verified that the device is not in hibernate mode, attempt to navigate the device by using the Hardware buttons.
If the display is still black/blank, Soft Reset the device by powering it off and removing the battery for 10 seconds and then reinsert and Power the device back on.
If the screen is still black/blank after the Soft Reset, you will need to perform a Hard Reset.
The hard reset will remove all of the customers’ data and settings and restore the device back to the state that it was in out of the box. Once the Hard Reset is done, the customers’ settings and data CANNOT be recovered. If possible, have the customer back up their data before proceeding with the Hard Reset.
Once the Hard Reset is complete, retest the device.
If the screen is still black/blank, the device will need to be replaced/repaired.
Screen has lines
Is the customer using a custom picture or image as their wallpaper?
Return the Wallpaper settings to one of the defaults on the device by going to Start>All Applications Arrow>Settings>Lock & Wallpaper>Change wallpaper
Is the issue seen when using the default wallpaper on the device?
If so, Soft Reset the device.
If not, advise the customer that the issue is with their custom wallpaper selection and recommend that they discontinue use of it.
Does the issue remain after completing the Soft Reset?
If so, rule out recent 3rd party applications that might have affected it, by removing them
Start>All Applications Arrow>Touch and Hold on an application to be removed and select Uninstall from the Pop-up menu.
Note: Not all applications can be uninstalled from the device.
Once all recent applications have been removed, power cycle the device and retest.
Is the issue seen after removing recent 3rd party applications and performing the Soft Reset?
If so, perform a Hard Reset.
The hard reset will remove all of the customers’ data and settings and restore the device back to the state that it was in out of the box. Once the Hard Reset is done, the customers’ settings and data CANNOT be recovered. If possible, have the customer back up their data before proceeding with the Hard Reset.
Once the Hard Reset and retest the device.
If the issue remains, the device will need to be replaced/repaired.
Unresponsive Touch Screen
Note: The device comes with a Capacitive Touch screen which will not respond to light touches from anything other than the flesh of the finger. Users trying to use their fingernails or any other object should be advised that they need to use the flesh of their fingers (firmly) to navigate the Touch Screen.
Verify that the issue is with the Touch Screen and not the device freezing by attempting to navigate the device using the hardware keys.
If you can navigate the device using the Hardware buttons, continue.
If you cannot navigate the device using the Hardware buttons, this issue needs to be worked using the troubleshooting flow for Device Freeze.
Check the device for a static cling screen protector, if present, remove and retest.
If the issue remains, Soft Reset the device.
Check the device for a carrying case with a magnetic closure; some magnets can interfere with the Touch Screen responsiveness.
If using one of these cases, have the user remove the device from the case and retest.
Ensure that the Charger/Data Cable is the one intended for the device by HTC.
Use of non OEM chargers/data cables can cause your screen to become unresponsive (due to the power being allocated to charging the task, and not the screen).
HTC can only guarantee items such as chargers that have been made, made for and certified by HTC. Our chargers have been tested and passed strenuous quality and safety regulations, and it is recommended you only use HTC chargers with your phone. You must be very careful when using electrical appliances; using products that have not been tested properly or that have not been tested at all could cause your phone to malfunction, or even in extreme cases, could injure you.
If the issue is not resolved by the previous steps, move forward with the Hard Reset.
The hard reset will remove all of the customers’ data and settings and restore the device back to the state that it was in out of the box. Once the Hard Reset is done, the customers’ settings and data CANNOT be recovered. If possible, have the customer back up their data before proceeding with the Hard Reset.
Once the Hard Reset and Customization process have completed, retest the device.
If the issue remains, the device will need to be replaced/repaired.
Hope someone can give us a better answer, but this is the best at the moment
UPDATE:
People if you want to fix your Phone just put this on the serch engine of XDA Developers "To solve the problem "Screen unresponsive" or "Frozen screen" by yourself", without the brackets.
The post is from "maybeture", and he say is working, if you read the replies, many people said it work
I'll do it to tell you
Tell me If you have luck
same problem it must be that it gets unresponsive for a few seconds or even minutes after screen turns off i have to slide it sloooowwwly to get it maybe its some loose cable in there dont know but really waiting for it to be hacked to have android
Same problem here with my father's phone. I'm going to replace the screen digitizer tomorrow and see if it works... it only costs 19 bucks so its worth the try...

Hi JesusOdin
I have the same issue but my question is
And all is right now?
I you have luck please tell me
Thank You
I've had similar issue with the lock screen at times. The problem is more persistant when the phone is in the pants pocket during hot weather or I am under heavy exersion. I think it may be related to the humidity. I have refrained from storing the phone in this pocket and rarely have any issue.
The phone is not weather resistant, an Otterbox might help but would be rather bulky.
was there ever a solution to this lock screen problem?
i heard it was something to do with the drivers...changing from v69 (at&t) to v63(t-mobile)
anyone know how to do this?
Well...
Tried to replace the digitizer and ended up cuting the ribbon cable of the display. I bought the screen and digitizer. Replacing the parts on this cel is not for the weak of heart.
The cel did work without problems afterwards.
I have a surround and lately its misbehaving.
The screen goes off within a second or two if I do not continue touching it. Sometimes it doesn't even stay for a second and goes off immediately. When the screen goes off, I notice the red battery light blinking. Sometimes its just in a reboot boot loop. If i am successful and able to reach videos and start a video, then the video plays fine.
Until the video is playing, the screen doesn't go off. I have tried a hard reset but it didn't help. I am on mango.
What might be the problem?

Fingerprint/Home stopped working

I recently damaged my opt because I let a water droplet stay on the home button for quite a few minutes, I didn't care to remove it and now the home button/fingerprint isnt responding at all.
Please tell me possible solutions ? every other thing is working perfectly(both hardware and software). I tried wiping data and cache, it didnt work, I tried dialing *#808# and under fingerprint auto test it says FAIL. any possible solutions ?
Well, seems that is a pretty damaged button. You may try the trick with rice and let your phone stay there for 24 hours and see, if you get the rest of the water out and pray. But I doubt, it'll help. If it doesn't: You need some professional repairing.

Fingerprint sensor stopped working

So, I took delivery of my G4 plus less than ten days ago.
Everything worked fine, except that the fingerprint sensor occasionally acted up. It would often fail to recognise my fingerprint, about one out of every ten scans; but i assumed that my dry skin had something to do with it.
Today morning, upon waking up, I noticed the phone had become unusually hot and switched it off for the first time in nine days. When I turned it on again, the fingerprint sensor was totally dysfunctional.
I tried unlocking with the sensor. No luck. Forget sensing my finger, it wouldn't even vibrate to indicate that an input was detected.
Tried searching for fingerprint sensor in settings. No luck.
Dialed *#*#2486#*#* for CQATest. Attempting to open the fingerprint sensor section resulted in an FC.
Performed a factory reset. Back to square one, still no fingerprint sensor. Initial setup wizard simply behaved like the phone has no fingerprint sensor.
All subsequent attempts to get it to work have failed.
I've been using pattern unlock, and while everything else works fine, the sensor seems to be unrecognized by the phone.
My guess is that it's a hardware issue, but I'm baffled by what caused it. I've been extra careful, never dropped it even on a bed. No water contact. It's stock, no sideloaded apps installed and bootloader untouched.
Google searches proved useless, as did a thorough search of XDA, Moto's forums and a subsequent call to Moto customer care.
Would anyone happen to have a solution? I've requested a replacement from Amazon, but it would be nice to have a quick solution handy if this issue crops up again in future.
Thanks!
check whether in the security settings you get a fingerprint settings. if not search in the settings searchbar for fingerprint. if nothing worked try installing a applock "applock" and try to enable fingerprint within them and try to unlock. an important thing is this one, try using a full screen app of your choice and tap fingerprint sensor. if it opens the softkeys your mobile is messed up with software, if it didn't open the softkeys then the mobile is messed with hardware. cheers

If the phone is still within the replacement window, get it replaced. Otherwise, you can:
1. Get it repaired at a Moto service centre if within warranty period (that way you won't lose warranty)
2. Get it repaired at a local service centre (only if warranty has expired and Moto is charging higher for the repair)

reboot itself

my phone random reboot itself, all of the time this 2 happens time, phone was locked, and i heard vibration and i see samsung galaxy note 3 logo on screen and loading samsung logo, why itself reboot? now for this day second 2 times , before was reboot itself ughhh i cant remember but 2017-06-04 , maybe battery fault? i dont know, i dont wanna waste money for centre shop. because i dont wanna repair this phone.
*** mod edit, added the following description by @myka_1997 from a duplicate thread:
of course wifi always scanning off - unchecked , passpoint unchecked, everything in wifi additional settings is unchecked. no matter that is unchecked and checked. PHONE STILL KEEPS RESTARTING FOR NO REASON. Hmm, my phone screen crack, from face front camera, but since yesterday i had no issues with reboots , yesterday started. i do wipe data factory reset, cache clear, and reinstall software lollipop. dont helped. so where the reboot problem? i dont used sd card now. when i put sd card no corrupted phone still reboots 30 times per day. from now.
***
Best recommendation is to re-flash to stock and test. Maybe some app is causing these reboots.
i flashed many times..... to stock...... nothing .... still...
Me too. Ny note reboot itself every 1-2 minute. And something force closed everytime.
After check to samsung servixe centre. They tell me if my mainboard is broken
oh dear.. my phone cracked from facing front camera. reboots every day one time. i pull out sd card.
If your phone has a cracked screen it means you've dropped it. If you've dropped it, it means you probably did some damage to it. You can't just drop a phone and expect it to work flawlessly for ever. Even if there was no sign of malfunction when you dropped it, odds are that it will stop working sooner than one can expect. Either try a new battery or just buy a new phone.
Might be hardware issue, already experience this, you need to unscrew note 3 and tighten back something at top side, it is hard to say. This one better watch youtube.

LG G6 fingerprint option gone

Looks like common problem, suspect it surfaced after recent upgrade to Oreo. There is a popup that says "Can't read fingerprint blah blah, if problem persists, reboot". Trying to access the fingerprint option, it is also gone from the Settings menu. Also have multiple agents with given administrative rights since I use this phone to access office emails and stuff, it does give them the right to delete fingerprints i suppose, but somehow it just happened out of the blue one day. Repeated rebooting, holding down both volume up and down type of rebooting, clearing cache, doesn't help. Based on simple search it is common enough this problem, but no good solution.' Stock, non root.
Will be grateful if anyone has any ideas. Thanks.

Try this. Turn off phone. Hold down power and volume Up and Down together for 10 seconds. It will start in hardware control mode presss power button and phone will restart. This should clear the fault.
Thanks for the suggestion, Sir! Much appreciated.
Actually that was one of the things I tried as well, didn't work though.

Try squeezing the phone a bit in the area between the power button and cameras. I've heard multiple reports of this working. Seems to be a not-so-great physical connection to the sensor. The newer software may be more picky about it.
I have the sprint variant. My fingerprint reader went out some months ago. I've heard some people were able to get it back, but I wasn't one of them. I'm glad I had the second year warranty now. I had to send it in to LG. They are sending me a whole new phone.

The exact same thing happened to me a few weeks ago. I tried everything possible, but nothing worked. I only had a year of warranty, and it had just expired 3 days ago. I had to send it to the LG service center. They replaced the entire back panel and put it back using the water resistant glue (I did end up paying for the repair). But my phone is as good as new. I suggest you do the same thing if you want it fixed.
This worked perfectly for my lg g6. You're a life saver. Thanks so much

Worked for me also. Thanks!
I replaced the glass back and fingerprint sensor myself....and trust me, when it comes to ANYTHING D.I.Y. I am useless....but even I found it simple.
Matt
In most cases is just a sealing tape stratify itself and because of this fingerprint sensor lose connection. Before you replace whole back and sensor you can try to replace sealing tape, in 90% cases I had with G6 it helped.
I solved it with another trick
I removed back cover and noticed the erased thermal paste under motherboard on SoC and glass panel
I cleaned it and applied new one put back cover now it is working without problem
Squeez is not permanent solution
