A71 Fingerprint sensor

Highlighted
SOLVED
Explorer

Just purchased an Galaxy A71 and the fingerprint only gets to 20% it is worse than the A50.
Samsung blames the tempered glass but the mid range phones have an optical sensor which takes a picture so a tempered glass will not affect the image if it is fully glued. Samsung is just making excuses for a shoddy sensor and pathetic implementation of the firmware.
SHAME ON YOU SAMSUNG

Wouldn't it be down to microscopic imperfections or patterning within the tempered glass that affects the reader? Being optical the sensor would need as clearer view as possible of your print.
Do you have a screen protector classed as in screen fingerprint compatible?

My hands take a battering daily so it's sometimes hit and miss, if my finger skin is damaged.

Samsung need to get Huawei to fix their bad implementation of the firmware

Can I put a tempered glass on a phone with in display fingerprint scanner?

Unless you have the galaxy s10 series, yes you can. Because the under display fingerprint scanners of other devices are optical based and light will pass through tempered glass so it should still work. However in case of samsung’s ultrasonic fingerprint scanner, the waves will get blocked by the tempered glass. Though a plastic screen protector will be fine.

Samsung is using this to try sweep their bad firmware away and tell everyone that a tempered glass is the problem, they just want screens to break to earn extra income.

Hi Neil_Za,

I know your query is over a month old, but I just want to let you know that I recently purchased the A71 and had the same issue with the fingerprint, straight out of the box, nothing added to screen. I put some moisturiser on my hands (rubbed in properly) and bingo! it added the fingerprint no problem. Hope this helps  :smiling-face:

Hi, how did you get it to work? My A71 just arrived today and I am having the same issue. It only gets to 20% before it goes off and says it cannot be registered. No screen protector, just the temp plastic one that covers on the phone which shouldn't affect it. I tried cleaning my hands/the screen and moisturising and still nothing..

Hi ClaudiaDSC,  

My phone was the same, just out of box, no other added screen etc.

It did take me quite a few tries but I managed to get there in the end. I discovered that it won't register if your fingers are too dry. Even now, occasionally, it doesn't register and I still have to dampen my finger to get it to read it. If I am out of the house, or in a hurry,  I just dampen it with a bit of saliva, (not dripping in it just a tiny bit like when your turning a page if that makes sense ha ha ) which seems to work as well.  I found the more I have used it the better it is working too, so now I rarely need to  do anything and it works fine. I managed to register 2 fingerprints in the end. I'm sorry I can't be more useful. I hope you get it sorted.

That's great. How did you manage it?

Moisturised but that is not the alpha fix, I found that it was the placement of my thumb on the sensor. I was using the front when in fact I should have used the central part of the 1st phalange to get a print, just like when your fingerprints are taken.

Hi Sha70,

Thank you for this! However it still doesn't work, although I've tried moisturing/dampening my finger. Tried like 4 different fingers/thumbs too and still won't go over 20%!

The only other thing I can think of to suggest is turning on touch sensitivity, if you haven't done this already? It is under Setting > Display > Touch Sensitivity. Other than that I am out of ideas, sorry.

Yeah I had already done this. It works now though!! Bizarre, took so many attemps but I woke up today and it just worked. After a Master reset and many other resets and hardware checks etc, I don't know why now haha

Hey Sha70,

Just tried your moisturiser method, and it works like a charm! Thank you so much for your tip!

Thanks a lot! I could register the fingerprints without this, but when using it, 80% of times I was not able of unlocking and I had to introduce the PIN. I have just change sensitivity and it works much better, but it is still far from the instant (no matter how quick you were), unlock  of my previous Huawei Mate 10. I am somehow disappointed as I decided to come back to Samsung and this A71 and in my first week, what I'm seeing is that it works slower in general 😞

Poor software implementation that is all. It seems to have a mind of its own. Some kind of personality. Sometimes it works registering fingerprints with moisturiser, but 80% of the time it does not. Sometimes it works buy putting your finger of a wet cloth before each scan of the finger - but sometimes this does not help either. Sometime if you let it aside for a while and when you try again after 20 or 30 minutes it registers very quickly your fingerprint. 

Another annoying thing is that from time time it doesn't recognise one of the fingerprints. Don't bother to try to registrate again that fingerprint - it will not work and it will annoy you to hell. Just leave it for half an hour and after that like a miracle it reads again your fingerprint.  

I made 3 updates and nothing seems to be changed with this problem. There are times that it works quickly and time that it does not want to work no matter what you do. You can try with or without the temperred glass. with wet hands, with moisturiser. it does not want to work properly and consistently.

So after 3 updates and after all the experience that I detailed above I can assume that it is a poor software implementation. 

I've tested the same tehnology on the chinese companies like Xiaomi and Huawei and they have faster unlocking and always reads your fingerprints. Besides that, on the chinese phones it works by reading the tip or the sides of your fingerprint - something that samsung does not want to work. The position of the scanner on samsung is too low and when you want hold the phone with one hand and want to unlock it with your tumb you have to make some streching to allow samsung poor software to read the middle of your tumb because it won't unlock by reading the edge of your tumb or the tip of your tumb. Others can, samsung can not do that or not all the time only 10 - 20% of the time. 

So if the chinese can do it please cut the cr*p samsung and work on the software and don't full us with things like don't use tempered glass, don't use plastic protectors ... your software tells us to not use fingerprints if we don't want to get annoyed.
