Fingerprint scanner problems - Galaxy Tab S Q&A, Help & Troubleshooting

Are the Tab S fingerprint scanners known to get worse with time? When my T800 was new, my success rate with the fingerprint scanner was something like 3 out of 4 times (so, it wasn't a great scanner to begin with), but now it got worse than 1 out of 10.

Will 5X have same fingerprint scanner as 6P?

So many reports about how fast hauwei's fingerprint sensor is, but never a mention if the 5X has the same one or a different one that LG came up with.
They are the same. Turn the phone on and unlock it within 600 milliseconds
I wouldn't be surprised if both of them are using Qualcomm's SnapID https://www.qualcomm.com/news/snapd...ingerprint-authentication-snapdragon-sense-id
It's based on a proven biometric scanning technology that does 3d scanning using an ultrasonic scanner.

[Tip] Make the fingerprint scanner work better

Hello I would like to share something I found out about the fingerprint scanner, that worked for me and hopefully for you as well.
When I received my Elephone P8000 I was disappointed that the fingerprint scanner didn't work as well as I hoped (about 50% success rate).
First I thought it was the Phone, but actually it was my own fault. and now it works 99% of the time
The wrong way: when adding a new fingerprint, I placed my finger at the exact same spot every time while configuring.
The good way: hold the phone like you normally would when unlocking the phone, and place your finger at slightly different places on the scanner when configuring (do not center your finger at the exact same spot).
I hope this helps.
That's the way I've done it since I bought the phone and my success rate when using the fingerprint scanner must be around 90% (no kidding).

Same here. Actually, I think my success rate on the fingerprint scanner is higher than 90%.
I'm getting good results from this
Depends on fingers skin too. Scanner dosn't recognise fingers a lot when having dry skin(washed hands a lot in a day) and had normal skin when entering prints.
Thanks for sharing, i getting 90% success rate with this method.

Fingerprint scanner question

How is the speed/accuracy of the fingerprint scanner after the recent updates? Its said to be slow and unreliable at launch time.
Is it now as good or close to the usual capacitative scanners?

Yes it is slow(even after update) especially when you try to unlock when the screen is off (takes 1 second), and on always on display it takes 0.5-0.8 s, sometimes it doesn't recognuze fingerprint. So compared to the usual fingerprint scanner, it's very slow, though it can be improved via updates

Samsung released another update earlier today that was focussed on the fingerprint reader and it has certainly improved the performance. Comparatively, it now takes half the time it took with the original firmware, though it is still slower than a capacitive reader. More importantly, the accuracy has improved a lot compared to the original firmware and it rarely fails, as long as the finger lands on the right spot.

[Q] How good is the fingerprint reader?

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)
It works perfectly every time, both in my XL and my wife's regular 3.
@Clancy_s I have tested the fingerprint reader pretty thoroughly by having others try to unlock with theirs. It has not failed. And it unlocks quickly for me

Mine works great. Not sure how secure it is but I like it. One thing to remember is the new GS10 has a new finger print technology so I'd try it out in a store if possible before settling on it.

This. Perfect every press, and works great as a notification down-pull if you just want to check them without using two hands, or trying to stretch to reach the top.
Fingerprint unlock worked great on my Pixel 2 XL and working similarly on Pixel 3 XL also
never failed to unlock

Fingerprint sensor useless

I have had this phone since September and came from Huawei P30 Pro, before that Honor V10, Huawei P20 which had fast fingerprint sensor and worked 99% of the time first time .
I cannot believe how bad this sensor is in real use, unlock success rate is about 5% no matter how many times I delete and Reregistered all fingers.
I scan my prints and test in the setup and they are acknowledged correctly but once I start using for real to unlock the phone or approve stuff it rarely works.
I have tried all kinds of angles and strengths of press but it's useless.
Running the beta in hope of improvement but it's still useless.
Did I get a bad unit here or is Samsung just totally crap with fingerprint sensors?

After you've registered your fingerprints.... re-register them to improve the accuracy of the scanner. Also, if you find it sluggish, reduce the animations in the settings...

I am reregistering prints to try and improve and after every update hoping something is better.
As said when setting up and checking it is fine but when I have to use for example with 2FA app to approve a log in it just fails "fingerprint not recognised" before eventually going to pin.
Will try the animation setting and see if that helps.

for a while, the Note10+ fingerprint reader had a terrible success rate, no matter what "hacks" i used to try to make it better (i.e. multiple fingers, the "test/learning" hack, etc.) — loads of "make sure you cover the entire sensor" and "no match found" etc.
this tip might be crazy, but it does work: MOISTURIZE LIGHTLY.
100% serious.
my right thumb was not able to unlock my Note while i was working at my desk. super frustrating. looked at my hands, thought they were looking dry, so i put a dab of glycerin hand cream on and BANG: every single damn time now, regardless of whether my thumb is vertical or sideways.
I got my Note 10+ today and have spend a long time setting it up. Once I registered my prints I had not issues (unless I didn't press firmly enough on the screen). It's been fine for me thus far.
You shouldn't compare ultrasonic fingerprint sensors that are in their early stages with optical ones that have been out there for years. Ultrasonic is much more secure. And saying that success rate is only 5% means that you either have a defective unit or need to change the way you use it. I have a success rare of no less that 90%... not as accurate and quick as my old note 8 with its optical sensor but I got used to it
I've had no issues with the fingerprint sensor, before or after the update.

heh yeah classic S10+ fingerprint reader from Samsung. I also found the same "you need to lick your finger first. Yeah, it's not a joke. " :laugh:
yep lick your finger first does actually work, if you have dry hands the scanner is mostly trash, use moisturiser/lick/damp your finger and it will work near 100% reliability. basically if you don't have clammy hands it will likely be hit and miss.
actually found myself in bars using the condensation on my drinks to help me unlock the phone, it seems an odd thing but it seems moisture in your skin is a massive deciding factor on it working.
