At first I thought it was either a fluke, or just not happening, but now I know it definitely is. I can press onscreen keys and buttons without actually touching the screen.
I've seen recently that there is a screen tech that registers hovering fingers but I'm not sure if the ClearPad 2000 hardware can do this. "I'm not sure" meaning "I have no idea."
Interestingly it is affecting the way I type as as I type and skim over onscreen keys, I will sometimes get that "run you finger across a piano" effect. If that's makes sense to people.
I do know that I have a habbit of giving an electric shock to many things and people. Maybe I'm just highly charged and it's affecting the screen???
Is it just me that gets this?
i just had a few try's and i couldn't do it, i had to actually make contact for anything to happen
AFAIK, capacitive touchscreens work by reacting to the natural hand capacitance (i.e. the tiny amounts of electricity stored in your body). Therefore, I suppose it makes sense that different people can have different levels of capacitance.
No doubt someone who knows will be along soon!
Sometimes, the screen can be very sensitive ... and sometimes, you can accidently touch the trackpad.
Yeah, I experienced this issue as well.

As already mentioned, capacitive screens do not actually register your finger touching the screen, but just the electric field your fingers produce when near to the sensor. The sensor in this case is actually a grid of thin wires spanned across the screen, you can see them when the screen is off and hold the phone at a certain angle to a lightsource.
So, depending on the calibration of the sensor, a finger will get registered even if you just hover over the glass.
No chance to hover and register a touch on mine, albeit when I hold the phone with my normal left-hand grip - my thumb being just above the volume key - it registers as a touch on the screen so a single finger slide doesn't result in a scroll but a zoom in/out. I really can't stand the length of the volume key.

perhaps its the optical track ball ???? That will do it ... 1cm away from the track area the screen moves. as it should
Nah, for me it's not an issue with accidentally rubbing the optical trackball. Plus I've tested this a number of times. I can hover a finger over the screen and get the screen to respond. So when the keyboard is up, I can type without touching the screen. Seems to work best with my thumbs. And interestingly, my right thumb works "better" (if I can call it that) than my left.
Maybe I am just highly charged. Especially when the weather gets hotter I give a lot more things electrical shocks. I'd better hurry up and get a protective case!
This has happened to me quite a lot. I wasn't entirely sure if just psychic? Hahaha!

Does it for me all the time, I can hover at a maximum of about 2mm above the screen and it still reacts!!

Yes this how my Desire reacts also, I can very very gently touch the screen without it being registered.
Hey Cleargrey,
I can confirm this behaviour on my Desire. The explenation given by petzlux is also correct.

Thanks. But I prefer to believe I have supreme ethereal powers.
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

Hey guys. My brother just got this phone and is having some issues. .. He's coming from Lumia 922.. So it shouldn't be too hard to impress him .. right? Well so far he has gone into airplane mode every call he's taken because the screen won't sleep and his cheek toggles to airplane mode. Is there any setting to help this? I want to give him a chance to like this phone, but if you can't even comfortably make a call without worrying about accidentally bumping the button maybe he needs to trade it ...
Any advice would be appreciated.
Does he have a screen protector on it? Sometimes those mess with the proximity sensor and makes the screen stay on.

I have a somewhat similar issue. I returned my first phone because I thought the proximity sensor wasn't working. I would be speaking on the phone, press my face to the screen and then would hear an ear shattering beep and then then phone would switch to speaker phone. This happened several times. I did have a screen protector on the phone but removed it. It continued even after I removed the protector.
I swapped the phone for a new one and all was fine for the first several days. Yesterday the problem started again. And, no, no screen protector this time.
I've noticed this with this phone, as well. I have a screen protector, but it doesn't cover the proximity sensor. That's in the metal above the screen, I doubt anyone's screen protector would affect it.
Sometimes when my face is literally pressed against the phone, and by proxy the proximity sensor, the screen still comes on and I can see it out of the corner of my eye. While it happened occasionally with my other phones, this has happened more in the week and a half I've had this phone than a couple months with the others. I think it might be a defect in the model if others are having this issue.
I've also had it turn on the speakerphone for no reason even when it's pressed against my face. Don't know if that's part of the issue or not.

Well it's nice to hear that I am not the only one having this issue, but frustrating that I am too. . If anyone finds settings or a solution let me know. . It's definitely annoying.
Must be a limited issue. Haven't heard of this from anyone I know and I have yet to have the issue.
I think I may have figured out my problem. I had an "el cheapo" TPU case (http://www.ebay.com/itm/Transparent...r-for-HTC-One-2013-M7-Accessory-/330949139388) on the phone. Today I put 3 different callers on speakerphone & mute simultaneously. Took the case off and haven't had a problem since.
Hi, I've searched this forum and the Internet in general about proximity sensor problems but it seems like basically every problem that someone else had was fixed by removing tempered glass/screen protectors/cases/covers. I'm having a proximity sensor issue and I'm not using any screen protector or case.
This has happened twice now. Once when I was listening to visual voicemail, once when I was making a call. The screen goes dark and will not respond to any wake commands. Every now and then it will turn on for half a second when I hit the power button but then turns back off again. The first time when I was listening to visual voicemail, I had to hard restart the phone by holding volume up and power. The second time during the call, I managed to hang up the call in the half second the screen came back on, which ended the problem.
Right after that, I tested the proximity sensor using the SMMI test (calculator .12345+=). The test makes you put your hand near the sensor, then away, then near again. During the test, the phone immediately sensed my hand near the sensor except that my hand was nowhere near the sensor and there was nothing else near the sensor either.
I did a reboot and ran the test again. This time, the test finished correctly. The phone did not detect my hand until I actually put it near the sensor.
I'm running stock everything except I do have root(ZE551ML). I'm leaning towards this being a hardware problem and I've only had the phone for a week so I'm well within my replace period with Amazon. Is there a solution to this I'm missing or should I just replace? I'm a firm believer in troubleshooting first. Plus, setting up the phone the way I like again will be a huge PITA.
Thanks.
I would replace. It does sound like a hardware issue, and your better off getting a replacement instead of a possible pain for the life of your phone.
I get the same, and the flickering screen happened once to me after I I have just put a tempered glas protector on it ... removed it and so far no problems, but who knows.
I think the SMMI test works correctly the first time you start it, and incorrectly the 2nd, 3rd etc ... dont think it is a hardware error ...
Hi all, i have a zen2 with this same problem, i think doing sensor calibration can resolve the issue... but i can´t found how to do, by code, or by app...
Any body know how to do calibration of sensor aproximty?
Thanks in advanced!
Ps. I dont have screen os glass protector...
i don't having tempered glass or any screen protector. my proximity sensor is not working. Even i checked .12345+= but it gives error in proximity sensor. what to do? plz anyone?
same problem
Hi to everyone,
I have the same problem with the proximity sensor.
After a device reboot, the simmi test work correctly, but after some hours the test fails.
Someone know as I can calibrate the sensor ??
Thanks
I just fixed mine, cause I was having that issue for a LONG time now.
I actually just stuck a piece of paper in front of the light sensor part of the sensor window on the screen. It's the right side of the sensor window.
To be more clear, a while back my screen broke, so I ordered a screen online and changed it. Ever since then my prox. sensor didn't work, so I couldn't use the keypad during calls (the screen would go black).
My screen still isn't attached properly, so it's just being held in by the floppy protective case I have on it right now. This allowed me to pull the screen away from the phone a bit and slide a piece of paper behind it right in front of the light sensor. As soon as I blocked the light sensor then the proximity sensor started reading properly.
I got the idea because I was trying to clean the screen, thinking that it might just be dust blocking it or something. That didn't help, so I tried cleaning the sensor, but had the calibration test running at the time, and it instantly worked!
So I kept playing around with it and noticed that every time I blocked the right side of the sensor, it worked, but as soon as I removed the brush I was using to clean, it stopped working.
I stuck a piece of paper in, and BOOM, worked just fine.
People might want to build on this and maybe try sticking a piece of tape over the right part of the sensor. I haven't tried it, and since I finally have it working now, I really don't want to play with it too much and mess it up.
Hope this helps anyone else having this issue.
Hi all,
I am using zenfone 2 laser z550kl. Screen blackout during call and did not come up till the call is cut. I changed only the cover of proximity sensor and phone is working fine. Change the small rubber covering of sensor and it will work.
Hope this will help all if still using asus phone.
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...
