Issues with fingerprint sensor in Marshmallow - Ascend Mate 7 Q&A, Help & Troubleshooting

Hi I recently got a second hand Mate 7 32GB (TL10) running on marshmallow (build 561). Love the phone and all but noticing that the fingerprint sensor is very spotty.
When fhe phone has been idling for a bit, a tap of a registered finger only wakes the phone maybe half the time, and the other half of the time the phone doesn't even seem to realize that a finger has been placed there.
I have tried reregistering my fingerprints but I notice that sometimes I will get repeated notifications to keep my finger still despite not having moved my finger. I've also cleaned the sensor but to no avail.. Does anyone have any suggestions of what may be wrong or what fixes there may be?
Much appreciated!

touch registering incorrectly ( tap or scroll)

hey guys
i'm running stock fw 5.1.1 gen, 16/2gb.Does anyone else notice that their touchscreen is just buggy? I am talking about things like scrolling and tapping a link from a list, for example. Sometimes the scroll or the tap will register incorrectly and usage can be erratic. i've noticed this especially while using whatsapp when i try to open one chat from main chat screen instead of opening the chat it just scrolls down
is this a common issue ? seems like a HW problem to me
Sounds similar to what I've experienced:
http://forum.xda-developers.com/2015-moto-g/help/touch-screen-fault-t3183555
.. I suspect it's a hardware problem like you, but I was able to reproduce the problem on two other handsets.
I have tried a couple screen protectors now... The screen on the Moto G seems very sensitive to them. If you have one installed, try removing it. The best response in a screen protector I have found is with tempered glass, and even then there is still a little bit of "error" in touches.
Not sure if this helps at all, just thought I would throw it out there.
I don't have screen protectors and I've noticed some degree of unresponsiveness, but only after the stagefright update. I've flashed the newer stock firmware (not OTA) and noticed the issue after using the phone for a few minutes.
I too have a tempered glass screen protector and from time to time I notice there are a few glitches.
Granted I applied it the same time when stage fright ota was released so who knows now.
I have this issue too and I am in the US. I don't remember if it happened before the stagefright patch. For me it is much worse when using swiftkey. The google keyboard does it very rarely on occasion. I do have issues that worry me somewhat with my touch screen though where sometimes when I swipe down it also swipes slightly to the right or left which doesn't happen on my old phone. Several times when my morning alarm is going off on my phone I will swipe in the direction of snooze which I had no issue doing on my old moto E but now on my new moto G the swipe to the left for snooze gets interpreted as a slight swipe to the right causing it to say alarm off instead of snooze. Luckily I noticed that so I didn't end up sleeping in. The moto g 2015 seems to have a much more sensitive touch screen than my old moto e 1st generation. I just hope this is a software issue that can be fixed and not some sort of hardware defect that would result in me having send the phone back and wait for replacement.

Fingerprint Scanner

Am I the only person who's having issues unlocking my phone using the fingerprint scanner?
I'm so tired of getting "Try again" leading up to it being disabled and having to enter my pin, I get a poor success rate. On average it works maybe 2/10 times.
When I scan my finger I move it around as much as possible, and initially I do get a pretty good success rate, but after I try again later it mostly fails and only unlocks when it feels like. I'm pretty sure I place my finger on the sensor in the exact same place every time; sometimes I give it a wipe with my finger before and it unlocks.
People who see I have the Z5 always ask to show how the fingerprint works but it never does. Surely if you scan your finger you have to keep it in the exact same state every time you want to unlock it, ie: clean, dry, etc...
It's so disappointing, it would be such a easy and fast way to unlock your phone.
I don't have any issues and in fact rarely does it fail first time

I don't have any issues either. There may be the very odd occasion where it doesn't work first time, but this is rare.
Add another finger and use the same finger again at even more angles

No issues here either but I will say the accuracy has improved since the 152 update.
Mine works great. As each fingerprint recording session requires 20 individual scans, I used three different fingers in one of the sessions for typical use cases, e.g. sideways thumb for unlocking in car holder, non-phone holding hand to unlock when on a desk, etc. Even the 3-in-1 sessions works well.
Do you have greasy fingers?!
Mines fine no issues unless my hands are wet which makes sense as your fingerprints change when wet
Sent from my Sony Z5 ooossshhhh
As above, it seems to be affected a lot by finger moisture. After training the print when my hands are perfectly dry, the scanner works perfectly, but when they're in any way damp (after hand washing, a little sweaty from the gym, heat, etc.) I was getting failures. So, I just 'learned' the same finger after getting it wet and this improves things a LOT. Had the same problem with the scanner on my S6, so this is really just a function of how much your prints must look different to the scanners in various conditions. Give it a shot.
I have problems too, and this is one of the reason why i'm gonna give it back...i'm really disappointed by this phone...

I definitely have issues with mine, seems to be worst when the phone is cold. The most success I have had is registering prints after I clean it off with warm water (ie post shower). If the green completion circle jumps from ~85% to 100% on your last scan, that's when you know you have good prints registered. I use my left middle finger to unlock the phone most frequently, so I registered the middle part of my print and then the tip of that same finger separately as 2 different prints and that seems to work pretty well. Doesn't take much dirt to throw it off track, but it's the most luck I've had so far. You definitely aren't alone with your issues

check the power button and see if it's flushed or is it slanted to one side?
Mine was slanted to one side, and my hit rate for finger print unlock is very low.
Just sent it in for service. will see if it changes anything
Good feedback, at least it's not just me having some issues.
I have noticed that the power button DOES move very slightly, but we're only talking about half a mill maybe. But even if it's in a perfect position I still get about the same result. It seems to me that finger moisture is a factor. Like I said once I do an initial scan it works great for a while, but eventually it seems to fail unless my finger is in the exact same "state".
Because the button is on the left I hold it in my left hand and use my left middle finger to unlock, I scan it in many different positions to try and give it a good variety yet sadly it doesn't seem to make a difference. I will try scanning the same finger a few times to see if I get a better success rate.
I'm currently on build 32.0.A.4.11 if that makes any difference.

I've seen it reported that there were fingerprint improvements made in 32.0.A.6.152. I'm on that version, experiencing no issues.
I am having the same issue. Currently I have 4 profiles of my thumb but sometimes I have to enter my pin anyway.
What helps most is to clean the sensor with my shirt, although no impurities can be seen. And no, I have no dirty fingers!
The odd thing is that i.e I scan my thumb and immediately thereafter, unlocking is not possible with this newly generated profile.
I did a quick look into the Z5 and I cover the fingerprint scanner a little bit here https://www.youtube.com/watch?v=lloEIZU8G3Q
It works well, but you have to make sure you have it mapped well too.
I have similar issues. The moisture of your fingers plays a factor for sure. Some point in the day it will work, but at another point in the day it will fail to read even though I place my
finger in the exact same position. I end up redoing the fingerprint learning over and over. It's starting to get a bit frustrating.
None of listed issues...
My fingerprint scanner even recognise me upside down and in all conditions
All running pretty well

From im getting louder clicking sounds it was first time that sensor doesnt recognize my finger saying that its dirty... so im going to take it to support. It didnt happen before i started to notice that i needed to press it a little more.

Fingerprint scanner fails to recognise my finger

Hello
I have been using my s6 from 6 months now. but this past month i have started having issues with the fingerprint scanner.
i have my right thumb registered 2 times in 2 different angles
my left thumb twice in 2 angles.
but despite of that my fingerprint shows no match. sometimes it detects my finger sometimes it doesnt.
I know my backup password and i can always log in using that. but i just want to fix this fingerprint issue. it is so irritating.
i used s5 for a year but never suffered such an issue.
and yes i have tried to re register the prints while deleting old ones, and even tried factory resetting but this issue persists.
please help me. and i do not have warranty coverage as my phone is international

Fingerprint sensor - discussion

Hello,
I’m using the Xperia 5 since this Wednesday (for two days).
My overall experience with phone is mostly good (for most parts of using even perfect). Unfortunately, these nice words do not apply for the fingerprint sensor.
It usually takes 2-5 tries to unlock the phone, sometimes I can’t even open the phone with the fingerprint scanner at all. (The error messages are: Not recognized; could not process fingerprint, please try again. Sometimes it says something with "partial fingerprint").
I tried rebooting recalibrating the fingerprint with the wizard then rebooting again. Nothing seems to help. I know this doesn’t have to be eventually a defect or something. Fyi, my thumb is not moist or oily, same thing applies for the reader. Maybe my thumb is just too wide, I don’t know.
What’s your overall experience?
Jakub
Same experience. Worst fingerprint reader I've used.
Same here, IMHO the worst fingerprint sensor I've ever used on a device.

I got it working but putting my finger along the side of it and not by using the thumb having the finger pointing out from the phone.
Mine works almost every time now.
But it is indeed not the best scanner.

So, you didn't use Z5 series. That was the worst fingerprint sensor. Fingerprint sensor didn't work more than it worked. This one on 5 is better but not good. Sometimes it doesn't work at all.
I have the same issue as well, as do many others evident from Sony Forums however the FPS works fine Banking apps, website logins etc

I didn't use a Sony phone with fingerprint sensor before
I am kinda used to finger print sensor being 99,99% accurate and reliable (iPad, Meizu, Nokia, LG, Samsung, Asus, Xiaomi etc.) so that's why I am surprised it can implemented so poorly. :silly:
Honestly after 2 weeks with this phone, I'm beginning to question whether it has a fingerprint scanner at all. Feel like I may as well just remove my fingerprints and forget it exists.

I sold mine last week, of same reasons. Useless fp, might as well be non existent.
I had to retrain myself with how to use the finger print scanner. With other phones, I'm used to using the tip of my finger, but that doesn't work with this scanner. As HellRoot describes above, I now lay the flat part of my finger against the scanner so that my finger is parallel to the phone (not pointing at an angle). Now I can get it to work very reliably.

Sadly not working for me at all.
Not to mention I encountered "flip case" bug when the phone is refusing to accept touch screen input to take a call.
This "Sony experience" is much more frustrating than I ever expected and that comes from a guy that used LG V30 for 2 years.
If they do not fix software issues with Android 10 update, I will seriously give it to my mom or wife and buy a propper phone.
My FP sensor worked perfectly for two weeks, I did not get a single "Partial FP detected" and was wondering what's with the bad press.
Then, gradually over the course of a day, it's started playing up. Now I'm in line with everyone else, frustrating experience at less than 20% hit rate. Android 9 or 10 doesn't seem to make a difference, tried factory resetting etc.
Checking the Service Menu (*#*#7378423#*#* from the Dialler --> Service Tests --> Fingerprint Test) returns the following:
Fingerprint Sensor Status:
Sensor not OK
Sensor HWID:
0x0603
I can't seem to find more information on this error code, contacting Sony has returned the typical "Are you running the latest software?" and "Have you tried restarting your device?"

I just got mine yesterday, pretty much everything work perfectly except for the fingerprint, and mine also show the same Service Tests info as yours.
When I scan my finger, it usually register only at certain angle, and usually only at my 2nd press on the scanner, which is quite frustrating
I really wonder if this is a software bug or hardware problem so I can have the store replace a new one.

But seriously they do not mind to use not so reliable devices. Xperia 5 is still an upgrade for Xiaomi Note 4 or Asus M1 Pro user.

It appears to be Software. I have issues only with unlocking the screen. The Banking apps seem to work fine (for now)

That's good to hear. I suspect so too because the service tests show everything was fine when I first bought the phone (it was running Pie at the time) and I started upgrading to Q soon afterward. And it was the 2nd day after I upgraded to Q that I notice the service test "Not OK" info.
Hope it can be fixed in the near future update and off topic: hope that update will also include patch for third party launcher to work with Q's Gesture (my most annoyed thing about Q)
Edit: After a few days using it, I realize it recognize the finger really well at certain angles. It never scans well with full finger but almost never miss when I use my finger tip or side. So I guess I can live with it for now. But still hope for improvement soon.
Well, other Xperias like XZ2, XZ3, XZP just got updated to 10 recently. And, all I've seen so far are complaints about 2 things: no swipe gesture (because the stock launcher hasn't been updated, which is rather stupid) and fingerprint on those devices all become less responsive. It took many times pressing to work, which sounds just like our problem.
So I guess this is a software based problem from Sony's side. Maybe some bad fingerprint driver I guess. Anyway, hope Sony is aware of this and get it fix soon with December security update (also hope for third party launcher patch too)

General Most Idiots way to make use of P6a slow FP

Well, I'm on A13 Beta 4.1
I have noticed FP is not consistent at all..
For some, it's unlocking after many tries or can't even register FP..
At first i thought it was an issue in A12 where FP is registering Thumb expression but unable to unlock fast enough (No. I haven't noticed but where my P6a can be unlocked with unregistered Finger)
After moving to A13 Beta 4.1 it got worst..
Just now I have noticed that FP is working completely fine when your Finger is little wet.. Yes, you read it right..
At first even I was confused but then after some searching and applying logic, i gotta know that If your registered finger is Dry, I won't be able to read it properly so Titan M2 chip just refuse to accept it..
But Once you made your finger little wet(Little saliva or less than drop of water which is enough to make your finger wet enough), It just unlock it in 1st try..
I tried it for around 2 days.. So yes, If you are having trouble unlocking your P6a, Just make your registered finger little wet & unlock it..
Before we start complaining about M2 Chip, we need to acknowledge that all phones which don't comes with security like M2 chip just unlock device instantly because they don't have additional security like M2 chip...
Sorry for bad Englis...
yeah I'm noticing the same thing... and you're right that the moisture (or oil) level in my finger matters. Sometimes I can unlock my phone easily and sometimes it just can't read my fingerprint at all. When that happens, I try to re-register and I would repeatedly get "can't read your fingerprint" errors. Even tried removing my screen protector, but same issue.
Started noticing it when I took a trip to a dry/hot city. Started noticing repeated fingerprint errors.
In fairness though, any amount of moisture on my finger resulted in my 3a XL not recognizing it.
I do definitely prefer the physical sensor though vs the under screen solution.
Odd thing is that I'm back home now where it's not as humid or hot or dry and suddenly having numerous issues with my fingerprint. I'm on Android 13 beta 4 and fingerprint was fine for 4 days or so. Tried re-registering FP today and I kept on having sensor registration issues as well as FP reading errors - repeatedly.
In fact, I didn't have much issues with the FP since I got the 6a a week ago (when I was on Android 12 and then switched to Android 13 beta 4), so not sure what changed. Going to switch back to Android 12 and see if that makes a difference.
FP is also hit or miss for me. I'm on Android 12 and actually I couldn't register my fingerprint few times when I bought the phone. In the end, after some reboots and setting all the apps up I managed to register my fingerprints but now sometimes they are scanned without issues and pretty fast, but also sometimes I get info that fingerprint is not recognized and I have to put my pin.
Im guessing most of these issues will be fixed with software updates. It seems this device may have been a bit rushed to market. This is typical new device stuff though.
