Fingerprint not working, and option disappeard from Honor20 menu - Android Q&A, Help & Troubleshooting

Hi everyone,
I broke my lcd, so I changed it. I change the lcd+plate, but every componant including power/fingerprint button are untouched.
And after repair, there was a system update, I agreed to install.
And now I don't have the fingerprint option available, nothing in the parameters, nowhere in my phone menu?!?!
I don't know if it is hardware (made a mistake unpluging an pluging back some connectors inside, power button included), or software.
The power button is still working but not the fingerprint, on my honor 20 it's the same bouton, so I doubt it could be a connector not well connected. And I don't whant to teardown everything again, only if I'm sure it could'nt be software related.
the face recognition is working, I never used it before, but now I have to use a faster way to unlock than entering my pin.
Honor 20 YAL-L21 -never rooted or software modified build 10.1.0.241 (C431E9R3P7 (but my bank app (only) tell me I'm rooted (long before that problem) , but I'm not!!)
Is there a know problem?
Thanks

Touch screen not working.

Hi guys. I'm totally new to the android/smart phone world btw. Anyways, I recently got my Samsung Galaxy S2... first thing I noticed, my touch screen wasn't working. I popped the battery in and out and then it started working as it should.
My phone was working fine this morning, then all of a sudden out of no where, the touch screen stopped working again. I've tried turning on/off the phone multiple times. I've taken out the battery and even my SIM card nothing... i'm worried.
Has this happened to anyone else? Is there a fix? Do i have to go through Samsung? I hope not. Incase anyone asks, I did not root my phone.
Any help/feedback would be appreciated.
When the touchscreen stops working... were you charging the phone at that time?
The first time i turned on my phone, was actually by accident and it was charging.
However, just earlier now, it was not. it was just sitting on my computer desk. The home button, lock button and touch capacitive buttons work.... but i can't get past the lock screen
you could try a factory reset to see if its software related, but it sounds like hardware. I would definitely Return the phone .
I guess I can't do a factory reset, since I can't get into any of the menus... man this sucks. I spent $900 *gulp*
To do a factory reset,
1. Turn the POWER OFF, pull the battery out and put it back again.
2. Simultaneously press and hold the Volume Up, Home and Power button
3. If the Samsung Symbol appears, release the Power button
4. A Boot Menu will then show, Use the volume up/down to choose wipe data/factory reset.
touch screen not needed this way.
oo that's interesting... I tried it. and it didn't get to a boot menu. maybe I was doing it wrong. I tried a few different ways, but no success. It turns out I have warranty with the store. They're going to replace it for me Thanks for the feedback guys. Awesome forums.
Something similar happened to me yesterday. When I had the in-box USB cable attached to a BoxWave VersaCharger (combined AC/DC charger), and the VersaCharger was plugged into 120V AC, the touchscreen would stop working. As soon as I unplugged the USB cable from the SGS2, or plugged the VersaCharger into a 12V DC lighter socket, the touchscreen would work fine.
I've got the same problem as the OP... I had my phone charging overnight and this morning when I first went to use the phone I could not unlock the screen. I could wake the screen via the home button, and see I had a missed call etc but it just wasn't responding to touch. BTW I can't remember if when I first tried to unlock the phone if it was charging or not but really this shouldn't matter.... oh and btw, I'm not rooted or anything either! Naturally I rebooted the phone but still the same problem....so I tried a battery pull and still the same problem. Just now I did a factory reset but the touch screen still isn't working! I guess this is a hardware problem so I'm going to get it fixed under warranty by Samsung! Gutted that I will likely be without my phone for a week or 2!
EDIT, UPDATE...
Well, I was just on my way to the repair shop Samsung warranty had told me to take it too, and I took my sim card out to put in my old Hero (the only thing I hadn't tried!) and I couldn't believe it but the touch screen started working fine again! Weird, but that is now my advice if anyone else has a problem with their touch screen not working - oh and I took the sim out whilst the phone was still turned on. Crisis averted!
UPDATE 2
Sadly this has happened about 4 times to me now and I'm just waiting for the inevitable next time. Each time doing a factory reset then taking the sim card out seems to bring the screen back to life (though last time not immediately) but I shouldn't have to put up with this. Problem is, I don't want to send off a seemingly perfectly working phone to get repaired as I fear they will struggle to notice the problem, never mind fix it! I'm hoping a new firmware comes out soon, in the hope that it may resolve my issues...
Me as well ...
I have had this happen to me twice now (Touchscreen not responding).
The first time I had just installed a game and thought it must have been related to that. Pulled the battery and no joy, left it for a while and it came back to life...
Second time I was surfing the web and it stopped responding, pulled the battery and left it for maybe a minute but no joy .... pulled the battery again and left it for probably 20min and it came back to life. When it came back up I noticed the livewallpaper had been turned off and my widgets were gone from the homescreen.
What I did notice when it wasn't working was it had "safe mode" displayed at the bottom left of the screen
Have the Same Problem
Have the same problem i Mine and was super exicedat first it worked fine and after charging the touchscreen stopped working i pulled the battery out and put it back in but no luckso im gonna return mine to the shop hope they replace it
Moral:AT FIRST SUPER EXICTED BUT NOW SUPER ANGRY
Same issue - Is there ANY way to save my data before I send it in for repair/replace?
Hi all,
As of this morning, I have exactly the same issue as the OP. Screen doesn't react to touch, with the exception of the capacitive buttons. I found a dude on YouTube that had the same issue: youtu.be/0oIdllWiV4I
The last thing I did with the phone before it started misbehaving was to answer a call. The phone was on the charger when the call came in - I can't recall whether I unplugged it before answering, or after, or at all during the call. Not sure it has any relevance anyway, only mention it because I've seen reports of people's screens no longer reacting to touch when the phone is plugged in to a charger (apparently it even states in the manual that this may happen).
Anyway, whilst all my contacts, SMS, photos etc are backed up to the cloud, the same can't be said for my app data. Before I lose hours and hours of progress in various games, or all my settings in numerous other apps, etc, can anyone think of any way to get access to the memory of the phone, bearing in mind the following:
I can't connect to Kies to pull a back-up because bluetooth is currently enabled on the phone and when one connects the USB cable, it says "Activating USB mode will deactivate Bluetooth. Continue?" but I can't click the Yes button
I can't connect in USB mass storage mode because I can't navigate to the settings menu entry to enable it
I can't turn Bluetooth off in order to get Kies working, becuase I can't get to the settings menu or pull down the notification bar to reach the power control.
I can't use Voice input to control the device (on the off chance there was a "bluetooth off" voice command) because (presumably with the most recent firmware I flashed via Kies a few weeks back) for some reason Vlingo is no longer the app on the double-home button action. Instead it calls Samsung Voice and wants to walk me through a first use tutorial, but I can't click the next/skip buttons
I installed via Android Market push the app belonging to www_remoteaccessphone_com as it promises to be able to remotely switch bluetooth off, but the website says I haven't installed the app yet, presumably because alrhough I was able to install it without touching the phone, it probably needs to be run at least once to set it up, and I obviously can't do that
I can't start Kies Air to try and get my data that way (starting it would require using the touch screen)
Kies via bluetooth isn't supported on Android
Needless to say, the data I'm trying to retrieve is on the internal memory, not the SD card. As you can see I've been trying all sorts of creative things, but I'm fairly sure I'm screwed. Any bright ideas I haven't thought of?

flash it with CF-root, boot into CWM recovery, do a nandroid backup after that, use CWM recovery again to mount USB storage, connect to your PC and pull everything off.

Thanks for the quick advice. I guess I'll need to use my girlfriend's phone to download CF-root and then transfer the SD card to my device. Quick question before I proceed though - is it possible to remove all traces of such tampering, since I've already made out with Samsung that I'm sending it in for repair, and I'm not sure they will honour the warranty if they see it has been rooted etc.

get a USB jig off ebay or amazon to reset the flash counter. should not cost more than 5 or 6 euros, shipped.
anyways you need to flash CF-root through ODIN if you are coming from stock. instructions are all in chainfire's cf-root thread.
Nandroid Restore
So I successfully rooted, used CWM to do a Nandroid backup, mounted the sd_card and saved the contents (including the nandroid backup) to my PC, reflashed the stock rom & kernel, usb-jigged it to get the counter back to zero/original and sent the phone in for repair. My efforts paid off as they repaired it without question under warranty. I just received the phone back and today set about restoring my backup:
Copied the sd_card contents I'd saved to my HDD back onto the phone
Re-roooted it with Cf-mod.
Used CWM to restore the backup I took before sending it in
It restored boot/system/data/cache successfully
selected reboot now in CWM
The result is that it is still missing all my apps. It only seems to have the "data" like my camera shots and SMS messages, system settings like whether bluetooth is on or off, the volume level, Wifi networks etc. So something was restored. But there is no Google Account configured, the lock screen picture is the default not the one I had beforehand, and as I said, all the apps - the main reason I did this whole thing as my personal data is all backed up to the cloud on a regular basis anyway - have not been restored. Am I confused? I thought a nandroid backup took a complete snapshot of everything, apps included.
Finding out the list of Apps I had in order to reinstall them is not an issue - I have a list of everything I had installed saved on AppBrain. But if I reinstall the apps, all the settings (or progress in the games) within those freshly installed apps will be back to square one, not where I left them, right? Or should I reinstall the apps and then restore the data partition over the top again?
Are you guys using any type of screen protectors, cause if you are, that may be the issue s their have been reports that the screen becomes unresponsive with certain screen protectors when connected to a charger.
However, if you are not using a screen protector, then I would suggest getting the unit replaced as you should not have to do anything, root or otherwise, to get the touchscreen working on a touchscreen phone

Nope, no screen protector or any kind of case for that matter. Anyway, that isn't my issue anymore. The touch-sensitive unit was defective, the phone was repaired under warranty. My issue now is getting my apps & settings back. I have meanwhile read elsewhere that Nandroid doesn't back up the apps - pretty deceptive "backs up everything!" "it is like time travel" etc comments around here then.
Anyway, I reinstalled all the apps I had previously, and thought by reapplying the data partition from the nandroid backup it might then bring back the settings for the reinstalled apps. Instead all it did was remove all those apps again - now I am really confused. How come the restore DOESN'T bring back the apps I used to have, but DOES remove the ones I subsequently install. Does Nandroid touch the apps or doesn't it?
Touch screen not working
So i am having a very peculiar problem related to the GT-I9100 Touch Screen.
I bought the phone from Saudi Arabia and I live in Bangladesh at the moment. So for now I don't have warranty.
I bought it on 4th of this month. It had 2.3.3. So I updated it to 2.3.5. I did not use the phone much before that so I don't know if this problem was there before.
So here is the problem.
First time I noticed it when i pulled the phone from my pocket and could not unlock the pattern. First I thought I forgot the pattern. After sometime I noticed that i could not touch the buttons. I was dragging my finger over the points but there was no connecting line. I restarted the set. But it still did not work. After sometime I took the battery out. And after that it started normally and unlocked. And the touchscreen is totally fine.
I tested it using *#0*#. And every single point in the screen registers touch.
After that this happened couple of times. First couple of days I thought it was a pattern unlock problem. But i tried PIN and Password even using no unlock. It happened in every case.
So after couple of days it totally stopped happening.
But from yesterday it is happening again. And today it happened 3 times.
So today as I had no unlock protocol i tried tapping Home twice. As this brings on the voice command menu. And for the first time i was in the phone without touching the screen.And first i noticed the Menu and Back Soft keys works.And the touchscreen still does not work. And i noticed some thing weird. Always some thing in the screen is Selected. In Menu the + Icon is selected. In first screen the Map icon is selected. Also in Recent Apps the first App is selected. So after a lot of reboots it is back to normal again. Now i see something interesting. In the Battery Usage Graph i can see some really sharp drops. 3 times. Looks like when this happens phones charge takes a nose dive.
So here is the Gist.
Info related the Problem:
1. Usually happens when the phone is my pant pocket for sometime. It does not happen if it is sitting on the table.
2. Touchscreen gets totally disabled.
3. I have no idea why this happens.The exact reason behind it.
4. Battery Charge takes a nose dive when this happens. See the attached images.
5. I still don't know how to bring it back. Sometimes a simple reboot works. Sometimes I have to pull the battery. And sometimes it works on its own.
6. Every other function of the phone works. Like music playback using my UE 200vi music keys using PowerAMP, Siri(Android version), Call can be received using headset.
Battery nose Dive:

dl.dropbox.com/u/30943431/SC20111116-202913.png
Also the selection
dl.dropbox.com/u/30943431/SC20111116-202146.png
So this is the thing. My biggest problem right now is, I don't know why it happens and I don't know how to bring it back from this situation. If I knew I could make sure I don't get it again or I would just fix it every-time. As when this happens I cant make calls or anything which requires the touchscreen.
So guys help me if you can by giving ideas. As i will not go back to KSA in 6 months. So buying a $550 phone unlocked was a total waste. As i cant use it here.
Thanks a million in advance.

[Q] My S2 reboots instead of turning off ...

Here is the problem...
Both when long pressing power button - and short pressing + taping on a POWER OFF button - the phone doesn't turn off It just shuts down, vibrates and then restarts. Didnt have this problem before - just noticed it today.
I use official I9100XXKE4 rom - never rooted the phone and never used any custom ROMs.
Any idea what causes the problem ?

Both when long pressing power button - YES thats how you reboot SGS.
Short press = screen off
Hold power button down OFF screen displays
You can always try factory reset and wipe data if you think you have a problem .

Just hard formated the phone using *2767*3855# method
(WARNING - THIS CODE FORMATS YOUR PHONE AND ERASES ALL DATA)
... and nothing still reboots instead of turning off.
I just long press the power button - wait for the menu to appear - the tap on a POWER OFF text - the phone informs me that this will Turn Off the phone - I tap on OK - and ... it doesn't turn off - but jus restarts.
Very strange I am on a train right now - and wanted to save sme battery for the final part of the trip - but looks like because of this problem - I am not able to turn off the device. OK - i phisically removed the battery - but it's not the solution of the problem for future I guess
Return to seller its not normal .

I know exactly what you mean. I had this issue amongst a list of others and it was really ****ing me off. After i updated to ke7 it was still the same. I have a bluteooth issue so installed Villain ROM 1.1 - That sorted the problem. The phone turns off and on like normal but still have the bluetooth issue.
I dont think you should return it until the new firmware is out
soved
Hi, I had the same problem too, the details:
1. I have never used a different ROM than the original.
2. I haven’t upgraded the original firmware.
3. When the problem happened I haven’t installed any software (recently)
4. This is not a software problem definitely
5. The problem began when I have finished charging the phone (the phone was turned off), I disconnected it from the AC Charger and it began to show the battery icon like if it was charging and a yellow triangle advertising that the charger doesn’t have the sufficient power to charge. Then I tried turning on the phone (it was really difficult to turn it on), when I finally turned it on I noticed some problems with the data network (really annoying), when I tried to turn off the phone, it begun to restart instead turning off.
6. I have been goggling since then, only one thing solved the problem is to clean the USB PHONE connector (I used a small clip to clean), there is something unclean (I can´t see, it’s something very little) yet but the problem has gone, all is normal now.
7. In a youtube video, someone has a comment that says: “I had to turn it in to the local samsung service location. They told me that it was corrosion in the USB port due to water damage. They charged me €70, and I'll pick it up tommorow.” This confirms the problem.
I am thinking that the USB connectors come with this problem, so we have to be very careful at the moment of charging the phone, maybe we should plug the charger to the phone before connecting it to the AC power.
Sorry for my english (it's not good)
freddysalazar:
first post. i rarely post, but wow, that solved it. it must be hardware related. i took a cotton cleaner(or what it is called) and cleaned it and it solved the problem. will not have the charger by my bedroom windows during snowy winter anymore. moved it to my dry livingroom

[Q] accelerometers, gyroscopes and proximity sensors

Perhaps this forum could help.
I received a used Xperia Mini [ST15i] as a xmas present from my bro-in-law.
It has Android 2.3.4 – Kernel is 2.6.32.9-perf
Build is 4.0.2.A.0.62
It had a lot of his apps on and foolishly I went into application manager and deleted a whole lot of stuff when suddenly the phone went into what I originally thought was a Haptic Feedback loop.
I was unable to power off so I had to remove Battery and restart from there. The loop starts slowly with one or two vibrates every 10 seconds then it becomes rapid and settles into an almost clock like rythm, two vibration per second.
I tried to get into settings to turn off the haptic feedback indicator but it seems like for each vibration [or tick] , an invisible ‘enter’ has been pressed somewhere on the screen so the only way to get into settings is to press the ‘back’ button and at the same time press the ‘settings’ button to interrupt the loop and after 5 vibrations or so I am able get into the ‘settings’ menu and un-tick the Haptic indicator. The phone goes quiet but the ‘clock’ or what ever process is looping continues. It completely blocks me out from doing anything unless I can interrupt it via pressing the back button.
To try get over this, I have reloaded the complete 150mb software via sony update. Afterward the problem still persisted. I have done both factory resets and still the loop process continues.
Have I screwed the Kernel? Any help or advice would be great. The phone is locked .
Sorry for you but it's an hardware problem (related to touchscreen). You have to send you mobile back to Sony.
Mine had the same issue out of the box and I had it replaced. The guy in the store told me it affects some batches (don't know which ones).

Possible solution for still existing fingerprint scanner issues?

Hi,
I've read this thread and disabled battery optimisation for "com.samsung.android.biometrics.app.setting"* on my Note 10+ and Tab S6 (Wifi).
On both devices the fingerprint scanner is faster :good:
... and it seems to fix recurrent unlock problems with my Tab S6 too
* on some devices it's named "com.samsung.android.biometric"
Important:
it's not known yet if this might have any negative side effects (as battery drain or burning out the fingerprint sensor).
I also did it. But it doesn't make the fingerprint scanner faultless...
Hi, am I the only one having a problem with the fingerprint reader after upgrading to Android 10? ?
I have probably tried everything. Factory reset and clear cache partiotion do not help. The problem returns randomly. The reader stops working, and when I try to get to the settings I have the message: "Finger print sensor calibration needed " or "finger print sensor doesn't respond, try to reboot your device . If the problem persists, contact support "
I checked everywhere and there is no such thing as calibrating the fingerprint reader. Technical support also couldn't help me with the problem, they only recommended to send the tablet for service. ?
The problem has never appeared before the update so I bet that the problem is new software.
Any advice what else I could try?
The reader, when it starts to work, works much better than before the update, unfortunately more and more often it does not work at all.
The strangest thing is that sometimes it starts working after a regular restart. I have no idea what to think about it.
Something similar... It sometimes works like a charm. It sometimes stops working, but no message and no way to use it in order to activate the tab. In that case I have to use an alternative method to. I suppose a fix could be released after this update to Android 10...
solved
Hi there,
I've solved this issue. I have tab s6 4-5 month and I couldn't even register the fingerprint. today I tried again and I found out that you have to touch the scanner very gently, do not press firmly. so I could register 3 fingerprints and it is working. even with unlocking if you press harder it won't work you have to touch slightly and it is working. still it is not reliable as other scanners but it works. i'm providing the video, you can see when I touch gently it is working, but If I press harder it won't register.

Fingerprint reader and PIN not working - unable to access phone

Took the Android 11 update several days ago. No issues until today. Did a restart on the phone, for no reason other than to restart it. Now, the fingerprint reader isn't responding, and my PIN isn't working either. I am in effect, locked out. I don't have find my phone enabled, so I can't unlock remotely.
I have the unlocked model, directly from Samsung.
Anybody have any suggestions on how to fix this?
power button and both volume buttons for 10 seconds. Duh...
