Fingerprint Sensor enrolls ok but stops working - OnePlus 8 Pro Questions & Answers

My Oneplus 8 Pro arrived yesterday and I am immediately having issues with the fingerprint sensor.
The FPS enrolls just fine with no issues and then immediately after the setup it works when tested, a few minutes later though it just will not work at all. I have removed and re-added 3 times now with no change, the screen looks clean and there is no factory fit screen protector on this thing
Anybody else? Unsure if this is a hardware or software issue and really would rather not have to return it.

Works OK for me. It's not very accurate though and only picks up the correct print about 30% of the time. The 7pro was better.

I saw a video recently that suggested the scanner got better with time and, to some extent, learnt the more it was used. I'm not sure if it's placebo affect but I've certainly found that to be the case. It was rubbish to start with but has become more efficient.

I have also noticed that when it works it does not feel that fast either.
Strange thing is, I just had to log in using my pin and the FPS worked just fine for Lastpass but then again would not work to open the phone.

video of multi-touch issue

Not sure if a video has been posted before, but here you go:

I have since replaced the nexus in the video.. The new one is running 4.4 but still experiencing the same issue.

Here's mine:
It's annoying, but also funny, sort of. Okay, not really.
I had similar problems, went through warranty - the replacement device they sent me is flawless.
And i thought my one is unusable.
But in fact its not even close to your problems lol.
By the way i found that if you put all ten finers on the screen and make them touch the highest and lowest part of screen at same time, the screen will automatically turn off as on the 2nd video.
And in the logcat it says that it was turned off by user, so its definitely hardware problem
Here's mine when I was still on 4.3. It's not as bad now after I let ASUS take a look at it but it's still no where near perfect:

Fingerprint accuricy

Hi.
Ever since I own the S7 Edge I'm facing a strange behavior with the fingerprint scanner.
I used all slots for fingerprints. Every slot for a separate finger.
Now the precision of the recognition is fine only for a few days, then I'm facing the same problem. An error-prone. With increased regularity I have try 2-3... times to unlock the device with my finger (most of the time I use the thumb).
After deleting and imputing the fingerprints again it works fine again for a few days. Till next time.
I already flashed another stock ROM for another reason but it didn't change the behavior.
Anyone facing the same problem?
Best. Misspelling. Ever.
Gotta agree, fingerprint lockscreen worked flawlessly first few days, but ever since I'm finding it more and more difficult to unlock the phone. Weird.

:good: Okay. Hope you enjoyed it.
But instead of just making a joke of it you could help me with my obviously bad englisch.

Only thing I can think of is the basics. Make sure you're on the latest firmware for your device (use Samsung's Smart Switch software to install the latest factor rom, if available in your country). Also, some people have reported improved fingerprint accuracy by enabling Good Lock.

I'm already on the latest German multi-rom. As I said noticed the problem before flashing this ROM to my 935FD.
I installed Good Lock a few weeks ago but had several problems like the color settings eg. Maybe I'll give it a try
in later versions. Also I don't use TW I like Google Now Launcher the best.
Hm. But it seems I'm not the only one. So maybe there will be a fix in further updates.
I read in another thread that the APD1 update really messed up fingerprint recognition accuracy. Could this be the issue ?

Nope.
This issue was already present on my device with Feb firware as i got it. But yes I read this, too.
Has always worked fine for me. The only time it has trouble is if my hands/fingers are dirty.
APD1 did not mess up mine (Rooted & Xposed 935FD Stock ROM) - works waaaaaayyyyy better than my S6E
I switched from the S5 to the S7 Edge (Exynos). I've always loved the fingerprint reader in the S5. There always seemed to be someone in the IT media complaining about how poor it was, but that just never seemed to be the case for me - custom rom or stock.
I have to admit that from day 1, I've struggled with the S7. With my S5, I had a fingerprint saved for my right hand thumb, right hand thumb while holding the phone with one hand, right forefinger and also left forefinger and thumb.
With my S7, I've had to use all of the slots for my thumb and although it improves a bit with the more fingerprints I've stored, I don't find it as successful as the S5.
I haven't done any testing with both devices side by side, but only a few times a day would the S5 give me problems. I feel with the S7 that it's lucky if I get in first time. Several times a day, I have to type the PIN backup.
I initially thought that it might be just getting used to the larger device. I'm not sure. I think I'll re-do all of mine and see if I can get a better recording.
I will say that when it works, it's a LOT faster than the S5, but I'm not that concerned. I'd rather have a reliable scan that takes a bit longer to unlock, than a fast unlock rarely recognises my prints!!!
FYI, this was true before the APD1 update and also now that I'm on that version.
After updating to APD1 I had problems with finger reader. Factory reset seems to solve my problem. Now its working much better with just one finger added,instead of 4.

Issue with fingerprint sensor

Is anyone having difficulty unlocking the phone with fingerprint sensor?
It used to work like 95% of the time, but now I can barely get it to work.
Not sure what changed... maybe since the last software update?
Mine works perfectly, like 98 or 99% hitted. x720, 18s official.
Almost 100% for me.
Try to configure again.

Thanks! Must be the changes to my skin when I traveled out of the country to a very different climate. It's working much better now that I'm back. Weird...

Fingerprint reading too slow

hi,
did someone notice the fingerprint too slow at reading or not reading well?
you can record 2 same fingerprint to let reading get a littllllle fast
Sent from my SM-A720F using Tapatalk
I've done that. Didn't notice difference. I work in a mobile phone store and I've seen some units and I tested in another a5 and is a lot faster...
Maybe is a placebo thing.
(Sorry my english)
I have the same problem here. Did that twice the same finger registering thing but nothing changes. I got an replacement from samsung but my second device (this one) has the same problem. Found no solution so far.

PUBG Mobile on essential

Has anyone else here played this game on the essential phone? I have a couple of strange glitches. I initially thought they were associated to my original faulty device, but after receiving my warranty replacement that is not faulty the same issues still persist on PUBG Mobile. So I am assuming it's something with this phone in general.
First glitch is some artifacting during the loading screen on the notch end of the phone. I am assuming this is because of the screen resizing to accommodate for the notch. It seems like it starts to attempt to resize the screen a few times in a row every once in a while resulting in what looks like some screen glitching. I've noticed this in other apps while using them too like chrome and OfferUp. Looks like every once in a while the app suddenly attempts to resize back to full screen mode for a split second, then immediately shrinks back down again to cut out the notch area.
Other issue is while using both fingers on the screen at the same time. Moving while aiming for instance it will spin my character around a little bit.
Doesn't display any of this behavior on any other phones I've ever had. I already contacted the publisher of the game but Wondering if anyone else has these issues and knows a workaround.

Strange, I don't at all. I full wiped and flashed from fastboot though. Did you ota?
So you still have the graphical glitches?
How do I get P?
Also is it possible to force games and other apps to utilize the full screen pace around the notch? As much as I don't like apple I do notice in YouTube videos that it does fully utilize the notch area on the iPhone X.
Alright nevermind found the settings in developer options from YouTube video to force all apps to use the notch area.

I flashed the ota through adb, did not factory reset though. I think the issue is involving the multi touch that was broken in and 8.1, and I don't think Google has fixed the issue

Like I said before, I flashed the full fastboot file, not just the ota. It is fixed completely. You could try that.
Yes! God, I thought I was the only one with the multi touch issue..but I'm too lazy and stupid to get P so I suppose I'm out of luck.
There's a fix for the multi touch glitch bug. It's a magisk module called "Pixel 8.1 multi-touch fix".
Let me warn you, DO NOT install it if you are on the stock essential ROM, because it will fail to boot. It is only safe on AOSP based ROMs. I can only vouch for myself that it works flawlessly with lineage. If you are on stock ROM you'll have to wait until essential releases a fix.
I just read up on it a little. Apparently it's an issue with all phones running 8.1.0 Oreo witch I did not know. My original essential PH1 was faulty, kept crashing and rebooting so I thought this was part of the faulty device.
Looks like they plan to release a fix in June security update.

The difference is insane right? Night and day. Even if there were any bugs, which I haven't noticed any, I still wouldn't be able to go back I don't think.
Way smoother, all touch bugs fixed, better battery life... What's not to like?

Yep, everything is great for a dev preview. I fixed my PUBG, by just uninstalling, then reinstalling the game. Runs flawlessly
