First, I have searched for this but came up with only instructions and tips on how to set it up, not my particular question (but it may be how I'm asking it!!). My question is whether anyone knows why the finger print scanner would accept my prints quickly and easily (meaning I don't have reason to think the scanner is faulty), but not work on my wife's at all. I'd like her to be able to easily unlock my 6P in the case of an emergency but it will only record her 1st print, then fault out on all subsequent attempts - on either index finger. It seems to accept any of my fingers, but none of hers. Can the scanner be slightly defective so only more prominent ridges are picked up (I'm talking waaay over my head here, just throwing out questions).
Any thoughts would be appreciated.
Thanks,
You might be hitting the finger print limit. I thought you could only store 6 prints.

Thanks, but it won't think it will let you do more than 5 and lets you delete them if you wish. I didn't want to completely delete mine but I made sure there was at least 3 available.

Thanks, but we thought of that, too. Had her try without washing her hands 1st, then after washing, then after wiping with alcohol - no luck!
I scanned both of my index fingers without problem. Sounds like you had no issues either... Any chance she's pressing her finger too hard? Not hard enough? Possibly she's scanning a portion of her finger and its not overlapping when she scans the next (no clue if this is a thing)? Maybe overlapping too much? I'm assuming y'all have tried repeatedly.... Just trying to brain storm
Hi, I am really confused. I have read that Moto G4 Plus is suffering from various issues like heating too much while turbo charging, ghost touch , display problem and even some hardware problems with in one week of buying, especially from Indian users. So If some out there has moto g4 plus and using it, it would really helpful if he/she could share the experience and suggest that should I buy it or there is some better alternative for the same price range.
Thank You.
I have ordered the phone but I have the option to cancel it. so Please help me out.

I don't think the phone suffers from any serious issues. Sure, ghost touch is an issue. But you can avoid it in two ways:
1) Avoid using it when charging. It is manageable, given it has QuickCharge and charges fast.
2) Using a 5.2V 1.35A Asus adapter, I rarely have the problem. Try a similar adapter.
As far as heating is concerned, there is a difference between the phone getting warm, and it being a frying pan. With my usage pattern (constant internet use, occasional photography), it does not heat up uncomfortably. Maybe so when I use it when plugged in the TurboPower adapter, but the previous solutions are applicable here too.
Apart from these, my display does not suffer from any issues that I noticed. NONE. Same can be said about the remaining hardware.
I don't know if later batches of the phone have any issues (I got one from the earliest batches).
One issue (more like a S/W bug) is when occasionally, touching the fingerprint sensor does not unlock the phone. If I wave my hand over the proximity sensor (or just touch it once), the fingerprint sensor works fine. It is most probably due to a bug in the part of the S/W which prevents the fingerprint sensor working when inside your pocket.
It may be fixed in any future updates.
To sum up, I am very satisfied with the hardware. I understand others may disagree, but it's my opinion.

Hi folks,
Anyone else experiencing issues with the fingerprint reader?
I've set up the maximum if 5 fp, but interestingly all the 5 are the same finger.... And the device won't recognise my finger ad soon as I lock the phone.
Tried with different fingers= same result.....
No matter what I'm doing, clean cache, re-set, etc....
I've already exchanged the phone but the new one is the same....
Any idea how to fix it?
Sounds like your fingers aren't compatible. Is it a common practice to have the same finger registered five times? Only have once perfinger myself and never have an issue unlocking.
My experience is it gets a lot better with time. I did make two entries for my left thumb which helped increase read rate from maybe 2/3 to >9/10. Other fingers read well and got better. In sunlight, in dark, no problem it just works. If your fingerprints are in some way unusual or hard to read it may "just be you.".
Do you have a friend whose finger you can borrow to test things out? Rule out the phone ?

I was really upset about not reading my fingerprints so I tried with the same finger and surprisingly registered again....and again.

Tried with my wife's finger. It reads a little bit better,but the overall successfully unlock by fp is way below the acceptable number (tried around 10 times, unlocked around 3-5)

Oh that's awful! I'm consistently >9/10 after a month and half of use. Even early on was probably75%. Only problem I have is right after a shower it doesn't like swollen skin fingers.
As a test I just did 20 unlocks using the various four fingers i defined. Only one fail, and that was left thumb at an angle.
Phone is definitely better than iPhone 6 I have for work (50% rate).

How does everyone register their same finger more than once? It tells me I've already registered that finger?
I noticed a dramatic improvement when I washed my hands really well, cleaned my screen, THEN registered my fingers.
Are you using a screen protector? If you are that is probably your problem.

Using the official oneplus tempered glass screen protector.
Yes compared to the Vivo and other phones in built fingerprint reader OP6T's fingerprint reader is slow and has some issues.
Got my 6T 8 days ago, love everything about the phone but the fingerprint sensor. Words cannot describe how aggravating it is. On a good day it takes at least a full second to respond. It does not work if I recently took a shower, if my hands are cold, if there is a minor amount of debris on my fingerprint, after washing my hands. The sensor fails to recognize my left thumb 50% of the time no matter how many times I redefine the fingerprint. I have gone as far as having separate imprints taken in bright and dark conditions, to no effect. When the sensor does work on my left thumb it takes twondull seconds.
I am THIS close to returning the phone while I can still do so. Have there been any rumors whether the 7 will use an ultraonic sensor? I love OP phknes but they blew it with the 6T sensor big time.
I have had zero problems with mine, even after applying a tempered glass cover it works great. I thought that I would have to redo my prints after installing the glass cover, but it worked just as fast as it did with the original cover. Maybe the sensor on yours is faulty and an exchange will fix the problem?

Running the latest beta and my FP sencor unlocks instantly..
Also change the animation to McLaren
Been using the 6T since the release, at first the fp was kinda slow, few misreads, but now (since a month or two) it works great, it can even unlock with half of the finger on the sensor. It even works if there is a thin layer of some substance on the finger. It was never unreliable for me. Now it works perfectly.
I had issues initially and didn't really like it, finding a lot of rescans to get the phone to unlock. After a lot of trial and error, for me, I found the best technique is to lightly put your finger on the scanner. It seems to unlock fine, first time now for me. I think the McLaren animation is just a perception that the phone is unlocking quicker. I actually have the animation disabled and don't notice any difference in speed compared to with it on.
It seems that the efficiency of the fingerprint sensor is highly dependent on ambient lighting. Things work somewhat well at night and indoor. Outside in bright daylight they generally suck. This kind of makes sense, one way to reduce this is to make sure that your finger fully covers the sensor area, with as much overlap as you can get away with.
FP sensor doing my head in on my McLaren 6T. Lately I have seen it becoming less and less accurate. It takes a few tries to unlock and sometimes I have to enter the pin since it will not allow any more tries. Tried deleting and adding the FP's but to no avail. Disabled the option for the time being. Probably the worst aspect of this phone if you ask me. Have the original glass screen protector on.
Mine wasn't great on the original T-Mobile firmware, but since I've converted to international 9.0.12 it's been flawless. Sounds like you may have a faulty device, unless you haven't updated?
I registered my dominant finger twice. It did the trick for me.
Bright lockscreen background and register finger twice has improved it a lot,bit it will never be as good as the standard Scanners
Mine seems to not work as well with my left thumb compared to my right. It isn't as good as my old pixel 2 xl fp sensor, but not horrible either. Just the left is wonky no matter how many times I re-register. Maybe light or my fingerprint.
This is def cutting edge technology through the screen for a fingerprint compared to others. But it ultimately works real reliably with my right thumb.

Try and redo all your prints in a dark room. Helped me out tremendously
My 6T fingerprint detection is as good as on my 3T, and far better than on my iPhone 6. I did have to register my left thumb twice to get good detection. I have no problem in the dark, interior light, or bright sunlight. In all cases with any of my four registered fingers I get 9 or 10 good scans out of 10.
The only circumstance where it routinely had trouble is "fresh out of the shower" fingers. The slight swelling or whatever due to warm water throws it off for sure. After 5-10 minutes it is back to working reliably though.
I have had mine about a month now and struggled with the fp sensor as well. I've changed the animation, re-registered the same finger/thumb twice, nothing seemed to work very well.
Here is what worked for me, when registering the fp, press very lightly. I'm used to using a standard sensor and always press very firmly.
My thought is that since it's through the glass, pressing too hard distorts the fp and results in problems.
My recommendation is to stop retraining it. It learns the more you use it (Oneplus confimed). Stick with it for a week and you'll see a massive difference. Mine is just as flawless as my OP3 now, No issues at all.

Ultrasonic aren't better, check the Galaxy one (even worst in some case), they are on the other hand more secure.
I cant get myself in using it, the face unlock beats me to placing my finger every single time anyways lol.

Try registering you left in a normal way you'd hold your phone..I faced the same issue but then I deleted the thumb print and re-registered it..Works fine most of the time

How did you do his? Every time I try it I am told that the finger is already registered.
On a more positive note after following some of the suggestions here things are definitely looking up. The stuff that made the biggest difference
1. Press lightly when defining FP
2. Register FP is a somewhat dim environment
3. Make sure they center point of fingerprint is scanned during the fist phase, so that the finger covers the green spot solidly.
4. Get a good sampling of the center and edge during the two stages
5. The McLaren animation makes a notable difference

I kept changing my finger position little by little when it showed already registered, to give the phone maximum coverage of the finger. Changing the pressure also makes difference.
Also the McLaren effect helps a lot in this case, I believe.
Not how convenient is the placement - I can tell that in store, what I can't tell and most reviews doen't mention is mean how quickly and reliably does it recognise your fingerprint and how often does it miss, particularly are there any circumstances under which it consistently has trouble?
My current phone is a Galaxy S8, before that I had a Pixel. I plan on getting a new one in the next month or so, short listed to Galaxy S10+ or Pixel3 XL. One of my favourite things about the Pixel is the fingerprint reader, which worked pretty much first time, every time - when I picked it up the phone was unlocked by the time I was looking at the screen. The S8 not so much; I can work around the smaller, less well placed reader but it often has trouble reading my finger print. I've reregistered, rebooted, cleaned the reader etc many times, to no effect, it still has trouble particularly if my hands are cold (for a certain value of cold, never below freezing around here), skin is dry, skin is wet etc...
My partner has my old pixel, I still have a fingerprint registered on it and the pixel still consistently reads it first time, even when the S8 can't.
For me this is one of the make or break features on a phone, it's not covered in reviews and will be hard to test in store, so I'm asking this community - how good is the fingerprint reader on this phone?
(I'm posting this on both the Pixel 3XL and S10+ forums, apologies to those who follow both)
Honestly it works fine for me, but i dont use it much, I use the face unluck, any reason why you guys prefer fingerprint over face unluck ?

Yeah, they implemented the ultrasound sensor to make sure this type of authentication can't be attacked.
Face unlock is a flawed method and this phone doesn't even have the hardware to do a proper face authentication, it can be fooled by a picture.
Samsung should have disabled it but chose not to remove any stock Android features, so it is still present.
Regarding my experience with the fp sensor, it took some time to get used to the position but once that happened it's pretty much 10/10, definitely the fastest scanner I ever tried.
It is very sensitive to how you register it the first time, you need to register it in a natural position and it will work perfectly.
Fingerprint is very inconsistent for me. I've tried every method for success and it's just very hit and miss. I really use face unlock more just for my own convenience. I know it's really not secure but my phone never is never far away.

Face unlock is basically all I use. Miss the note 9 and my pixel 3 xl fingerprint sensor dearly!

You should ask how bad is the finger print unlocked instead how good. For me need two or three to unlock the screen
I really wish they would have left it on the back. It was flawless back there on my s8 plus. I love everything else on the phone but that. If it was more reliable this would be a non issue
When you get used to it, it's still only like 80% accurate. Randomly it will unlock super fast and other times it fails alot. It's really average.
I'd say about 90% but it is getting better. I haven't installed my white stone dome glass and currently using zaggs. I think more people are having trouble finding the sensor and placing their finger on top of it. Try turning the screen on to see where you need to hit and get use to it. After I've learned where it is, unlocking using fp has significantly improved at least through this screen protector
I was having issues until I added an additional finger but kept it the same one I have setup already. Now it works flawlessly.
When I initially got my phone (2 days before release) I registered my fingerprints ASAP. I did each finger twice and it worked alright, not the greatest but I assumed it was just a learning curve and muscle memory that I had to develop. I installed the newest update (ASBA) and it didn't seem to improve, initially. I removed my fingerprints and added them back, this time only once per finger and it honestly works better than before. I didn't do anything special when I deleted and added them again. I wonder if the fingerprints need to be added again after the ASBA update to actually benefit from the improved fingerprint recognition, as it appears that way for myself.
Fingerprints that are added on the s10 & s10+ get better over time with some ai trickery, google search s10 fingerprint ai, theres a sammobile read up...

In my S10+ is as bad as my A7 2017, I mostly use Face Unlock with "faster recognition " disabled, with that option off it won't be fooled with a picture anymore.

Had never issues with fingerprint reader. As I wrote somewhere else, best thing is to press softly when registering it and touch the sensor sometimes more right, left, up and down as you usually don´t hit the sensor exactly in the center in daily use. Anyway there was a little latency until screen woke up and maybe in one of ten cases it didn't work at the first time.
Now I did what you suggested. I deleted the former fingerprint and set a new one. And it´s not only some kind of feeling, it´s indeed much better now. Latency nearly has gone and the fingerprint recognition works absolutely perfect now. So thanks a lot for your advise. Obviously it is not the "AI" of the device but the "user intelligence" Samsung is learning from. The recent update did it - fixed it. Great now, thanks!!!!

I agree with you, is crap, I have to touch several times and if my skin is dry because of the climate compared to when I registered the fingerprints (much less climate), much worse.

I'd say that's the biggest issue. It has difficulty recognizing your finger when it is dry (and that is according to the climate). When I registered them initially it worked great because my hands were slightly more humid.
At times I have to rub my hands on my hair or something to get it to recognize the fingerprint. There has to be something that Samsung can do to fix this. Especially given that this is the only secure method to unlock your phone.

Maybe you're actually just a reptile, or alien race? Honestly, I have no problems at all with the scanner. I don't understand what the people who do have the problems are doing because IMO it has to be user error. I'm not saying it's flawless, but I never have to re-attempt a scan more than once. Which is pretty much on par with how often I'd need to retry with my S8+.
Now, I don't use a tempered glass protector, only the factory one that came with it so that might be an issue some people face. But honestly, everyone who wines about the fingerprint scanner are probably just too stupid to use it properly or something.
