What is the best methods you find to improve the Success Rate of Fingerprint Scanner

[blackinfinity]

So yes just lets admit it, The fingerprint scanner on Vivo Nex is not perfect, but what it represent is forward thinking which will force other manufactures to follow, but we all know that Optic under glass fingerprint scanner will have to make room to the far superior ultrasonic technology.

despite this I am interesting to know what method you people are using to get higher success rate ?

The first question that comes to mind does it really help to save multiple fingerprints for the same finger ?

Even though I mostly my thumb to unlock where it is hit and miss the index finger have a lot higher success rate, and I wonder why.

Dry hands seem to be a big problem for the fingerprint scanner... I therefor tried to save a new fingerprinting when my finger are dry, I cant say it any visible improvement. It is still frustrating that my index finger seem to work a lot better on the fingerprint scanner.

Fingerprint scanner seem to work better in dark room rather then a well lit room or environment.

please posts your findings how to improve success rate especially for using the thumbs.

I think there is still hope that the fingerprint scanner will improve further in future software updates.
I also think, people will have a different success rate because of biological versions, some fingers are maybe harder to read then others for some reason. Lets hope Vivo will push out more updates for the fingerprint accuracy. This is their first device aimed for the global market so lets hope they will give this one extra care since this device will be the bridge into the global market..

I use multiple fingerprints for one finger and think it's much more reliable than one saved fingerprint.

Interesting that my index fingers are also working much better with only one saved profile instead of my right thumb

Vivo Nex S is recognizing your already saved fingerprints. Nevertheless you can simply save the same fingerprint again by moving and trying different positions from your finger. I actually saved my right thumb three times and surprised how good it works (for the first 3 days)

Actually 2 months now I’m very pleased by reliability accuracy and smoothness of 3D underscreen fingerprint scanner.

Thanks..I thought that had been tried in youtube videos I think I saw people say its does not help to make multiple fingerprints for the same finger... it should not be needed..it should be smarter then that..
especially since you press the finger multiple times when you setup a new fingerprint.

Well anyway I will try it..I guess it can be worse then what it is now....
Its frustrating that the index finger works so well..and not the thumbs...

I saw some review where they said that someone unlocked their smartphone with an unregistered finger...
This fingerprint sensor is really not reliable at all

And funny, i asked Vivo on facebook about this issue, Joe just told me "use a password instead" ...

Unfortunately Joe from vivo isn't a good supporter :/

To be honest I don't trust any videos about finger print scanner. If somebody wants to troll all they have to do is register the finger and state on the video that finger is unregistered and just troll the Vivo Nex owners about how unreliable the phone finger print scanner is.
I tried several times to unlock the phone with any finger that is unregistered and 100% of the time the phone doesn't unlock and send me to unlocked the phone with the pin number.
And the finger print scanner works 98% of the time with me on my registered fingers, I noticed the other 2% is because my fingers are wet or dirty from working out.

I scanned my thumbs fingerprints and it works better with the left one. Even after a rescan of the right one

I didn't succeed in making a second scan with a finger already stored

Of course I don't know why

 

[megich]

The accuracy is fine,however there is another interesting notice-you don't actually have to wait with your finger on the screen until the phone unlocks. You can simply put the finger for a second,release it and then wait a bit more for the unlock. That's quite intersting user experience and it makes the visibility of a faster finger recognition process than it actually is

I am sorry but I do not believe in this method...
Remember when you create a fingerprint you scan your finger multiple of times even from the edges etc.
Theoretically it could only lead to even slower scanning.

Anyway success rate have improved a lot the last 2 days not sure why...
Hopefully its learning and getting better for each day. I still hope vivo will solve the speed.
one frustrating thing is the screen dont unluck directly even when the scanner have read your finger for instance I cant put off my finger before it gets unlocked and it unlock...
I hope next update will come with some improvements regarding fingerprint scanner cause I think it does not live up fully to its potential right now.

It seems that the unlocking process is actually quite fast. There is a delay because of the animation. If you turn off animations in developer's options unlocking would be faster.

Enable double tab to wake screen
Then
Double tab screen
Use fingerprint
This make it ultra fast anf accurate

Always find my right hand not working fine with fingerprint??

 

[ruk21201]

Make sure the position you scan your finger is in the same position you unlock ur phone, I found this to work 8-9 times out of 10

 

[blackinfinity]

what I have learned lately is, its good to not push too hard on the screen push very gentlely it seem to be easier to unlock. anyway I think this scanner still need software updates to improve it have problems in well lit scenarios, luckily I am a night bird..

Yes I can confirm push the on screen scanner gently always works brilliantly,in few scenarios I pushed it harder didn’t response some time with first attempt.

Overall experience 2.5 months I’m very pleased with accuracy,response and smoothness as long we learn his trick.

Always helpful if someone experience not so good response or accuracy to register 1 more time from beginning it’s finger and tested one day continuously until been successfully.

And repeat 1-2 times to find their best performance to his own way.

I just played with the fingerprint yesterday and I feel that it works better when we press harder I added the fingerprint in the dark, with a minimal backlight pressing the finger firmly.

I sorry for my English, I use Google Translator.

Fingerprint scanner has been updated with latest funtouch software , Rescan your fingers, you will definitely see and feel an improvement ?

Do you mean the global or the chinese rom ? I use the chinese rom, I think nothing was mentioned about fingerprint scanner improvements in either of the latest firmwares of global and chinese. Anyway I will try rescan my fingers I have nothing to lose.
