Z5 Dual Fingerprint Scanner Problems

Dreday — Tue, 24 Nov 2015 01:05:17 GMT

Hello,

Scanner is very finicky. Sometimes it works, sometimes it doesn't. Tried registering multiple ID's using the same finger. Tried safe mode. Diagnostic test fails (doesn't vibrate) during safe and normal mode.

I bought this phone because of the fingerprint sensor (lots of sensitive business info in the phone), so i'd love for it to work normally.

Any suggestions please?

Try repairing the phone with Sony PC Companion.

Oh wow, mine has been a bit tempremental too and it's not passing the diagnostics test either. I guess I need to do a system repair too then...

solution of almost every problem is software repair... what kind software installation has been done on these phone and all of them are broken? I have both z5 and c5 ultra, no matter which issue of which phone I am looking, the solution is not changing, it is of course software repair... oh man you could release and distribute these phones with correctly installed softwares...

Software repair or phone reset doesn't help..
I've same problem on my Xperia z5 dual. Fingerprint scanner accuracy is very bad, 50%. And diagnostic test fails, as in nothing happens when you do fingerprint diagnostic test, most likely software problem with the diagnostic test.
I'm facing this problem from day one, and after a few days i restored phone software using pc companion and phone reset option for a issue caused by UStaminaM and this problem still persists.

I ve also noticed diagnostic of fingerprint does not react at all.. Oh man this kind of errors only might be at beginner level on s/w... How these producers do this job simce years, even very simple things do not work, who are beta testers of these sw, final users??? Oh nooo, there must be something wrong, final user must be the one who use with no problem!!

Hi,
My fingerprint sensor is not detecting anything.. Whenever I switch on the screen, the phone automatically vibrates and the sensor is locked. It also failed the diagnosis test

I've found that when you go to register finger prints, slide your finger on to the button and leave it there for a bit, try and do it fairly slowly, but not too slow as it registers your print as you're sliding before your finger completely covers the scanner.

Start with the middle portion of your finger, and move with the length of the phone.....

I made/~~stole some pictures~~ a picture.... to help explain....

With each scan, try and scan a section of your finger along side the part that you just did, until you get a majority of your finger.

Then repeat the scans in a way where you actually depress the power button, as a "pretending to unlock" and "scan my finger" movement.

Don't try scan your finger in the way I've shown below... or you could, but just use a similar way to register your fingerprint like I've shown in the example... but in my experience, sliding it up along the length is more of a fluid motion if you pick your phone up with your left hand and scan/slide a finger on your right hand up along the side until you hit/depress/cover the power button

Once the middle of your finger (where all the swirls on your print begin), reaches the middle of the power button, just pause for a moment, and let it register

**EDIT: Also if you have your phone in a jelly case, or any type of case for that matter, you decrease the surface area of your print scan, by going across the length, instead of along with it... which is more likely to cause mismatches

I just received the Z5 Dual and there is no option to setup fingerprint under security settings, its just not there, where it should be. But when I go to apps I can see the fingerprint manager is there. Any ideas?... I did have to software repair my phone the day after I got it, because the pin unlock didnt unlock, but everything else had been ok since then, do you think I need to try a repair again?

Sony PC Companion doesn't work. Can never connect to the server for apps or updates. Downoaded the new Xperia Companion as well, same issue. added rule in the firewall, disabled it as well, but no luck.
