My capacitive touchscreen has been having a pretty odd issue. If I lay the phone on a bed or desk and try to use the touchscreen with only one finger, I get all sorts of weird input on the screen. Then, if I touch the phone casing while repeating the same motion with the same finger (anywhere on the side of the casing or rear panel) the touchscreen works flawlessly.
Right now, my device is sitting on my bed, if I unlock it and try to pull down the notification window shade with just one finger, it's impossible. If I touch the casing with another finger and then try to pull down the shade, it's flawless.
From my understanding, in a capacitive touchscreen, a layer of electrons (ions?) is passed over the screen and a sensor detects where the flow of electrons is interrupted by the electrical conductivity of the human body. It seems that my phone is having issues with the electrons not just flowing over the screen, but around the casing as well, causing issues.
Anyone else experiencing this?

This appears to be a significant issues of owners of the HTC Incredible. You might get more useful information in that board, seeing as how they've been experiencing it for much longer than we have.
Wow, the video that they have on the Incredible forums of the phone on the Styrofoam is exactly the same issue I am seeing on my device.
I would link it, but apparently new users aren't allowed links. Ugh, this is a real bummer. Especially since that guy had 2 replacements sent to him, both with the same issues.
I too am experiencing this. I want you to try something a little different. Pull the kickstand out and stand it up on the bed. Then put your finger on the kickstand and you should be able to pull the notification bar down all the way to the bottom and let it lock with your other hand while still keeping the finger on the kickstand. Then take that finger off of the kickstand then slowly bring the notification menu bar back towards the top with your finger. Tell me your results. And i'll let you know if we had the same.
It appears that HTC has got some serious quality control to enforce on their recent devices. At this point, releasing a flagship phone with these issues is nothing short of unacceptable. I'm as big of an HTC fanboy as they come, but I'm really considering switching loyalties to Motorola is this crap continues. It's bad enough being capped at 30fps on the Evo.
If I put my finger on the kickstand I can pull down the notification bar completely, without issue. When I let go and pull the bar up, it works, but looks like it is trailing behind where my finger is by about a half inch, until I get roughly 3/4 of the way up to the top then it passes my finger like i'm not touching the screen anymore.

That might be the touch input lag we're experiencing as well. This may be tied to the 30fps graphic limit on the Evo.
The 30 fps limit is disconcerting, but that seems like it is something that could be fixed through firmware, however I doubt this issue is fixable.
Yeah, that's the exact same response I received from it; except when going back up, i reached the 1/2 way point on the screen and the notification bar shot up.

Well this is slightly depressing.
Ugh, my curiosity got the best of me, and the results aren't pretty.
When I lie my Evo down on a flat surface, the notification bar becomes absolutely impossible to pull down unless another finger touches any part of the phone. A test on the multitouch visualizer app shows that the screen completely stops recognizing my finger when y1 is equal to 40. This is essentially the entire height of the notification bar.
This isn't a deal breaker in any way, but what the ****, HTC? Is this how you treat your customers?
On mine, my screen becomes effected as early as y=500, then gets really bad around y=250, then is completely unresponsive after y=100.

wow, that blows, mine does the bad response -40 thing. holy ****, it's really just one thing after another with these phones...
I guess there is no such thing as a perfect phone no matter how much money, research, and time is invested into it.
I too have this issue, I have noticed occasionally its hard to pull out the notification bar, but when I pick up the phone and pull bar with other hand it works perfect.
For the heck of it I tested my Evo on every surface i could my hands on from glass, to thick carpet, bed sheets, etc, etc. Mine doesn't seem to have this issue, so it's definitely not every phone. If it's a big issue for you, you may want to see about getting it replaced.

Thanks for the thoroughness of your test!
http://www.youtube.com/watch?v=_kJ_fR02suQ i recorded it so people can see what's going on.
Have any of you contacted Sprint about this? I'd definitely try to get it replaced ASAP if I were you, hopefully the next one won't have this problem.
I spoke with a lady from HTC today and she said that they were aware of the grounding issue before it was released (during training). She didn't say whether it could be fixed or not though.
mine works perfectly fine i just tested it right now

Forget all the "you need to not press hard" bull****, it's way simpler than that.
Register your finger while holding the phone in one hand, position your fingerprint on the sensor exactly as you would casually, keep registering it that way, from a limited position on a one handed held.
If you do a "proper" registering process of your fingers from artificial positions just because you think it helps the sensor, it won't work, even minimal changes in your finger shape will make it generate different keys that will not match a real life press.
I registered my fingers from positions I would practically use to unlock later on, the success rate is now 100% as long as I don't miss the sensor on dark screen, no matter the pressure or the time you hold your finger on the sensor, it will now work every single time

I tend to agree with you. I registered both right and left thumbs and they both work on command. No 2nd or 3rd attempts yet. Just register the thumbs like you would naturally hold them on the screen(flat).
I also feel like the fingerprint scanner icon is a bit misleading, given the fact that the sensorbis actually above the actual icon

But when I try to casually tap the screen to register fingerprint naturally, it won't register, keeps saying press harder or hold longer
Or register the same finger twice.. That's the better solution

The tap needs a certain amount of pressure, not too light either

Same, and i registered the finger I'm going to be using most twice. Registered casually and from a natural position. I think mine has failed to unlock maybe 3 times in a week. In this case...keep it simple don't over think it.
Sensor is off
I noticed when the screen is off in dark mode and u take a flashlight on a angle of the screen i noticed the sensor is like a U shape just slighty to the left of the finger print icon, now that i kinda setup my finger print just a tat left og the finger print icon its been 100 procent i also noticed moist fingers work better . i could be wrong about it being a sensor but the U shape i think would be the sensor

You don't need to move your finger away, the sensing part of the sensor is perfectly aligned in the middle
New update on firmware.Science for snapdragon. SBA TO SD3. Made a world of difference for me. Can't wait for my replacement Whitestone to get here to see if sensor works any better with tempered glass. This update absolutely made a huge difference. Not slightly, very significant change for me. I register both thumbs twice and I couldn't get it to not unlock every time. 50+ unlocks and maybe 2 failures. I stopped counting at 50.
Will it work on verizon or only unlocked?

I'm waiting on my Whitestone replacement as well. Can you keep us informed on how the sensor works with your new install? I had to pull the last one. It was horrible. I miss my glass...
The problem for me and many people is that when the finger being scanned is dry, scanning won't work (and will be asked to "press harder"). Some people then try to press really hard and it will, forever, say "not match".
People with moisted fingers will not have this problem and will not understand the kind of people I mentioned above. Since I have S10+ for a month, I, kind of, know when the scanning will not work. I will use face scanning instead or if I really want to scan my finger with whatever reason, I just rub my nose with my thumb then it will 100% work (greasy nose does the trick).
I don't know if Samsung can ever fix this since it is not how accurate the reader is.
Dry fingers don't work with the fps even when removing the pre-installed screen protector?
I am debating to remove the screen protector and my main points are:
1. The protection offered by the pre installed screen protector is minimal either way.
2. That the screen colors and usage will become much better.
3. That the fps will work much better even with dry fingers due to the oleophovic coat of the screen.
Has anyone who removed the screen protector tested this?

I removed mine yesterday and it does help a little with the fps. I still don't like the fps though, I would much rather have a Face ID equivalent. Or have the fps on the back.

I had reached out to Whitestone because my first install failed. I had the WSD on my s9+ and went through 5 or 6 in the year (I dropped my phone a lot). So I knew what I was doing, but the first try had a huge bubble. Tried doing the cleaning and reinstall with the backup glue and had a bunch of microscopic bubbles in the top and bottom (guessing I didn't clean it well enough before reinstall). I wasn't sure how to register warrenty wise because technically it worked fine, just was having FPS issues. They ended up replacing without me paying for the shipping which was awesome of them.
Recieved my replacement today, and the install is flawless. One thing to note is on the 10+ the absorb pads hook into the top tray not the bottom (that was a hell of a mess the first time). The original kit didn't come with the pads pre-installed like the replacement kit.
I haven't even gotten the latest OTA yet, and with the WSD glass, it's just as quick and success rate is the same as when I had the pre-installed protector. Might even be faster than my s9+ was...
Hopefully I am not the only one with these issues. I am coming from an old Huawei device, Faceunlock was instant, if it got the slightest view of your face it unlocked, On this you have to hold it up right in front on you which makes you look like a **** and even then it sits spinning, there is a good second or so delay.
The onto finger print again another disaster, very slow and sometimes just doesn't work. I've registered several fingerprints but doesn't make much difference.
The easiest option seems to be using the swipe unlock code method. Disappointed with this.
Anyone else having these issues.

Face unlock is good for me, it detects even from a far distance. Try registering your face again.
Fingerprint after may update has been improved but still not the best.
Add your fingerprint by pressing the same area of your finger continuously, (move it a little if it says "please move your finger or whatever" and then start adding the same part again) don't add the edges of your finger, I've noticed that adding edges/corners of your finger makes it slower to detect.
Yeah, this phone optical finger print is crap, the worst among other optical finger print phone. I guessed samsung enginer sniffing glue when design this phone
I haven't used the facial recognition, but the fingerprint scanner is pretty bad. I'm coming from an LG G6 and the G6 was miles better. I am hoping this is something that can be addressed in a software update, but I'm not so sure about that. Might just be ****ty hardware.
Got the phone few days ago. Most of the time, fingerprint works on first or second attempts. But now and then it takes 4-5 attempts. and on two occasions i had to try 8-9 times to get it to work. Is it a problem only i am facing or its a common problem? i already updated phone after buying. should i get it replaced or it will be ok with next update
Thanks.
common problem i think. not as fast as the previous one on N9
Well, it is not widespread or "common", some users complain about this, but this issue has been discussed at lenght since the first days of this device, do a search, you will find some useful tips, My sensor is very fast and accurate, I think it depends on several factors, temp, moisture, the way you registered the fingers, screen protectors, etc
Also, register the same finger multiple times... I believe you can add 5 fingerprints....
I understand what you are talking about. I was so frustrated with the phone when I first got it. I deleted all my finger prints and then set them up again. Make sure to slowly follow the fingerprint instructions when adding. I added multiple fingers and some more than once. I have not had any issues since. I have also read some people say remove the factory screen protector. I still have mine on with no issues. Good luck!

did you have the same issue as mine? like u had to make several attempts and sometimes even 8-9 times to make it work?
only time I've had problems with mine is when my hands have been extremely dry, putting slight moisture on my finger can make it scan better, but for the most part it works perfect unless I'm somewhere hot and dry.
I have similar issues when I have a screen protector on the phone. Sometimes I have to press multiple times, sometimes I have to press harder. Finally going without anything on the screen and the sensor works like a charm.
Screen touch sensitivity.
On my Note 10+ 5G (SM-N976U) I have a setting on the Display page (scroll down near the bottom) that increases touch sensitivity specifically for use with screen protectors. The screen itself is Gorilla Glass 6, which is twice as strong as Gorilla Glass 5, so, if you are the careful sort, you can get by without a glass protector. Even with an extra curved glass protector, with touch sensitivity turned up, I can use light gloves & still the capacitance works fine.
Touch sensitivity has nothing to do with the fingerprint sensor.
Mine works perfect with screen protector. Sure if you put new screen peotector, it takes time to recognise finger. But when protector sits perfect than no prob at all.

the sensor works well as long as you don't have dry hands, lick your finger/thumb and it will work every time, sad but true. it's something I realise after it working flawlessly while drinking in a beer garden with condensed glasses but the rest of the time it was hit and miss. seems if your skin is too dry it doesn't read well, but add a bit moisture and it works perfectly. guess it has something to do with the technology in the new sensor using vibration instead of imaging.

Yes, lick your finger everytime you want it to work in the midst of a pandemic that seems to be spread by the virus getting transmitted from the hands to the face everytime you touch it...

The other advice I've found is to set up multiple finger prints with the same finger (you can usually set 5 fingerprints). This will improve the hit rate of the fingerprint sensor...

Yes it's maximum 4 on this device, it helps a little also
Hi,
Do you have cases when the fingerprint wont unlock the phone (until 5 failures are reached)
This happens to me every now and then and is quite annoying. I don't have a screen protector and have disabled battery optimization for biometrics. Wondering whether to bring the phone for repair.
Did you update to ATE6? If not, please do.
Also try to re-add your fingerprints again, i found that speed and quality of fp sensor depends on how "good" you scanned your fp-s.
Another trick is to press harder when scanning and unlocking (which also works).
Yes, I am on ATE6. Will renroll fp to see.
The issue that I've noticed what it could be is the scanner is always active. The problem I face is when I pull the phone out of my pocket I've reached my attempts and have to use my pin.
In the case of the other post, just add 2 of the same finger. My thumb and pointer are in it twice each

I don't have this experience with pulling out of the pocket. Added the finger again and now I am trying to train myself how to press harder and hold the finger patiently until it unlocks.
Adding same finger twice solved this problem for me, when adding second time make sure to scan your finger in different angles, almost like youre trying to miss scanner
S20 here. New tip. I think ultrasonic fingerprint reader is located slightly off-center to the left, so when adding and scanning your fingerprints, aim slightly left.
I discovered this yesterday while cleaning the screen under a bright table lamp, I noticed that you can actually see exact reader's location, where it is bonded to the screen underneath it. I assumed it's not visible.
Reader appears to be letterbox shaped, length around 1.6, width around 0.7 centimeters.
When you turn the screen on, fingerprint icon is located in the center of the screen, you can almost fit another icon next to it to the left, to represent reader's length.
Combined with other tips, some also mentioned by the users above, I rarely have to scan twice now, three times tops. Before I often ran out of allowed number of attempts and had to enter password. Still not perfect or super consistent, but much better. Soo..
Main tips:
• When adding and scanning your fingerprints, aim slightly left. Always keep reader's shape and position in mind. Turn off your screen, and examine it under bright desk lamp, to determine exact reader's shape and location.
• Register your thumb two times for each hand, while rotating your phone (slowly from portrait to landscape, back, and beyond until phone hits space between your thumb and index finger) and move thumb slightly towards finger's bend point and then towards fingertip (do it all over something soft in case you drop it while rotating).
• After you added your fingerprints, lock and unlock your phone multiple times (let's say 10 times) using each hand before you decide if doing it all over is necessary. Maybe even keep it for a day, see if phone manages to optimize data, or maybe you will get used to positioning your fingers in a certain way.
• Make sure to moisturize your hands, noticed scanner struggles with dry skin.
• You may also try to register both left and right thumbs (or other fingers) at the same time, this may speed up unlock, though not sure how secure this is.
• Don't hold your finger for too long, simply firmly tap and lift, phone should unlock.
I would try extra sensitive screen setting in display and try re register fp again.
I've heard some registering same finger twice but I don't really have any fp issues after disabling optimization of the biometrics apk

I remember having Touch Sensitivity alway set to on, believe it helped with gaming a bit, but found it had little or no effect on fingerprint reading, was constantly running out of attempts, and was forced to enter password, which is very inconvenient when you're in a public place. But I think it's still worth a try, maybe on S20's that option is somehow interconnected with fingerprint scanner, and boosts something in it as well, but I personally noticed no improvement.
Disabling battery usage optimization for "com.samsung.android.biometrics.app.setting" in "Optimise battery usage", did not improve recognition. I think you should still do it, as it can reduce occasional delay, but if you're using your phone all the time, locking and unlocking, etc, and having reader problems, this will not improve recognition. When it says no match (press harder, cover entire sensor, etc), it means software and scanner are working and reading your fingerprints, but failing to match patterns, so disabling optimization will not improve anything in this scenario. You should delete and try adding your fingerprints again.
Now, after registering same finger twice I noticed immediate improvement in recognition, and looking online for different tips of how you should hold your phone while adding fingerprints, was able to improve recognition even further.
Along with tips mentioned in my previous post, I now rarely have to go beyond two attempts.
Maybe this improvement also has to do with us instinctively learning what works and what doesn't.
Maybe this also has to do with finger size, skin (space between and width of friction ridges), and skin type (dry, oily, etc), that's why we have so many mixed reports. Also hygiene. I noticed with excessive hand washing, number of successful recognitions decreased, even with well moisturized hands.
In conclusion I'll say there is definitely room for improvement here, maybe larger more powerful ultrasonic readers are the answer, maybe better software. Because even with all the tips and tricks, it's not perfect, at least in my experience.
Oh, almost forgot, that factory screen protector has to go. Better fingerprint reading and much better picture quality without it.
And of course, make sure all the latest updates are installed, to all the people who just got their phone out of the box.
I typically enroll 4 of the same finger. I only use my right thumb and really haven't had any issues. I have the WhiteStone Dome glass installed. I have increased touch sensitivity turned on.
Using a poly screen protector with only two registered finger. Working perfectly with absolute zero issue.
