Iris scan wont work - Samsung Galaxy Tab S4 Questions & Answers

So just venting, but new Tmobile s4 wont register the Iris scan. It looks very badly out of focus and never adjusts to the eyes. Any others having this issue?

Same for me! But it registered my eyes before I put on a milky display protector with cutouts for the 3-4 sensors on top.
Don't know if this is the trigger for my problems, but I reseted my biometrics yesterday and can't get iris working again...
Any way to clear data for the biometrics app?

Works fine for me.

Been having this issue too... Just got my device today and Iris scanning doesn't work... Is the preview supposed to be blurry when trying to register? I haven't applied a screen protector or anything and nothing is installed on mine as far as I'm concerned

Screen rotation problem. Camera is bad.

Why this happen? Its the only phone screen rotation doesnt work on home screen.. Only on internet and with photos. I guess the sensor is ok, but its a bug?
I bought the phone today. It came with 1.2.5i version and upgraded to 1.2.7i version.
Also the camera photos are worse than my old nokia n8. Is this normal? :crying:

Fingerprint Sensor Stops Working

I've been using the fingerprint sensor on the 5X to unlock the device since I received it on the 21st. Today, my phone suddenly stopped recognizing my fingerprint. I went through the following steps:
Restarted the device.
Deleted my fingerprint and tried readding it, but it wouldn't recognize it there either.
I tried adding all my other fingers with no luck.
Had my girlfriend try her fingerprint (which she added yesterday).
Restarted the device again.
I'm hesitant to reformat as I'm happy with my device setup and I'm hoping there's a less destructive fix. Am I the only one with this issue? Any suggestions?
It's also worth noting I've made sure the OS is as up-to-date as possible.
Are you using a screen off app? I was using Screen Off and Lock through a gesture on Nova Launcher and because of it the finger print scanner didn't work. Seems to be a problem on any of those apps.

Screen Lag in Netflix When Touching Fingerprint Scanner

Just wandering if anyone else experiences the weird issue i have. So i'm in Netflix app watching something and if you hold your finger on the scanner while something is playing does the video Lag for you or is it just me? Because it lags when you hold your finger on it then stops when your not. Any advice would help
I just tried it and I got the same thing. Very strange. I thought maybe it had something to do with the fingerprint reader always being active for the swipe down gesture but I turned that off and it still happened. I also tested with the apps for YouTube, Amazon Prime Video and HBO Go and none of those had the same issue.
The Netflix app does support the Oreo picture in picture feature. Maybe that is related somehow?
Either way I don't think it's a huge deal. Not something I've ever ran into until I read this post.

Fingerprint gesture unresponsive.

Hello everyone, I bought my lenovo p2 last year and it was all working fine but for the past couple of months I have been facing some problems with the fingerprint gesture. Whenever I use it, it works fine for a few minutes but gets unresponsive after a while and when I touch it, it doesn't respond and sometimes I have the drag to the right to get it working. Is there any way that I can fix this? Thanks.
Facing the same problem but I think it can be made right to some extend by deleting the fingerprints and re-registrating would fix it
Mine is the same case too. My fingers leave marks on the scanner making it think that i didn't lift my finger up. Had to wipe it off everytime before using. Started happening aftet leaving stock rom.

Proximity sensor stops work Android Pie

Does anybody has problem with proximity sensor in Android Pie?
For me it stops work after half day and only reboot helps. In Oreo I haven't this problem
I've gotten this problem during calls
Update: proximity sensor stop work in phone app. With other apps its works without problem.
Interesting. Has worked for me but I've only made a handful of calls since going to Pie.

new update: looks like I found why proximity stops work. I use Cube Call Recorder and this app after a couple calls "kills" proximity sensor in dialer app. I removed Cube and now everything ok.
I'm having this problem too, but I don't have any sort of call recording app. Randomly it just refuses to put the screen to sleep when I'm on a call. Really frustrating.
Same issue here, since few days I have notice that the proximity sensor during phone calls will not turn off the screen, only reboot restores sensor functionality that's annoying, also I have this pixel 2xl for 2weeks this is an irritating issue. Hope help comes soon.
P.S
No new software has been installed on this phone that I have not used on my previous phones essential ph1 and Samsung Galaxy S8.
Cheers.
Couldn't find this thread earlier.
I'm also facing the same issue now. Android Pie.
Anyone found a Solution?
#5 was my problem
