Touchscreen sensitivity issue - Samsung Galaxy S8 Questions and Answers

Hi everyone I just this phone today at Verizon. They installed the temper glass and told me the screen would be hard to use for 72 hours.... I can barely type have to press pretty hard takes multiple tries. Trying to swipe the menu down too is a pain. Anyone else experience this? Will this problem go away?

I experienced this aswell. The problem is that this "glass" is only glued to the edges of your phone and therefore it's not completely flat in the center. I really tried to fix this somehow but I ended up removing this glass and just apply a normal protection foil.
And yes, this does not protect me from screen cracks but at least from scratches.

Screen Alignment Problems after Screen Replacement

I dropped my iMate and the screen cracked. I had the screen replaced by PPCTechs and they did a great job. The device worked properly after a hard reset. After a few hours of use, the screen alignment drifts off. Typing on the onscreen keyboard becomes difficult and eventually impossible. After a soft reset and realignment of the screen, it works well for awhile.
Does this sound like a problem with the new screen or was something else maybe damaged (memory) in the drop? Has anyone else experienced a similar problem?
Fixed
The folks at PPCTechs recommended I peel back the screen protector 80% and smooth it back down. Evidently the screen protectors can develop "hotspots" that cause this behavior.
I have known the touchpad to cease operation if the screen protector is tucked under the edges of the front cover but I have never heard of misalignment due to air bubbles. I would try what they say and if the problem persists I would return it to them and ask for it to be fixed.
It's been working now for a day without problems. BTW, there wereno bubbles. PPCTechs installed the screen protector when they replaced the screen and did a very nice job. I am guessing it may have to do with temperature differences between the protector and the screen itself.

Screen not working

Hi All;
My screen seems to have stopped working as of yesterday... the centre of the screen when off now has an odd pattern to it, almost like when you rub two pieces of glass together and there is some water between them. The phone is rooted, but I suspect this is more than likely a hardware issue (as in my screen is p00ned...). Has anyone else had this issue?

Touch screen issues after removing screen protector

So I removed the included screen protector since it had a deep scratch on it. I read on the forums that you don't need the protector and that it actually works better without it.
Well my experience has been the complete opposite. Ever since I removed the protector I'm ready to smash this bloody phone. It's next to impossible to use due to the humidity in my area or something. The SMALLEST amount of moisture on my finger tips or even in the air will cause the screen to go haywire and register touches all by itself. Apps will open by themselves...i can barely type anything as it keeps typing multiple characters on it's own or other silly stuff. If I wipe down the display it will work fine for the first little bit until it gets that tiny bit of moisture from my fingers on the screen again and it starts going haywire again. It's a hassle just to try and unlock the phone from the lock screen at times.
So is my phone defective or is just the suffering I must incur by living in a humid area. I can't use the phone like this so I guess I'll have to look at buying a new screen protector. But if this is not normal and is a fault in my hardware then i would like to return it and get a different phone. I didn't really have issues with the screen protector on.
Ive kept my screen protector on my phone, works fine until i have moisture or (rain drops) on the screen, then my phone doesnt respond and also misfunctions the position of where i touch on the screen not sure if this is normaly as its the rain drops on the screen..
Tested witht he iphone 4 in the rain and works brilliant, why doesnt the X10 do the same !! :/

As you may know, those screens are capacitive displays, that means they're activated by sending (very) small amounts of electricity and are kinda "looking for a conductive material" in order to register an input.
The conductive material can be your finger, or something like... a raindrop or your screen, so that's why it thinks you're pressing that part of the screen...
Now it's even more obvious without the screen protector since it's directly on the screen.
As for why the iphone doesn't have issues with that, it does, but the screen being multitouch it's not as bad...
thanks for the info.good to know.
I didn't like the thick screen protector as my thumb/finger seemed to drag and not slide smoothly. I took it off and replaced it with a slightly thinner protector. I'm much happier with the feel now.

@smok3yjk - probably best if you do as Angelahp - get another screen protector on there.

[Q] Capacitive button tester

Is there a tool that can test/adjust the sensitivity of the Epic's capacitive buttons? Mine seem unresponsive and I'd love to know if the hardware is not sensitive or the software is ignoring the taps.
Something that displays a readout showing which button is being pushed would be really useful.
Thanks,
Jason
there really isnt. its being classified as a hardware issue. i swapped the board out on mine the other day with a returned phone and it started working. taking the phone apart to fix the button at the bottom is a complete pain in the face. and if the gorilla glass faceplate comes out (which needs to happen to swap out the buttons) then it never really goes in correctly. nor does it stay stuck.take it back to sprint and see if you can do a 30 day exchange on it.
Thanks. I got mine at Best Buy and have their insurance. They'll fix/replace it for free but they have to send it to their service center and give me a loaner. I almost replaced it within the 30 days but when I took off the screen protector (Skinomi) to give it back, the keys were working great. I decided to hold on to the phone. Now I have another protector on it (Realook) and am having the same problem. I'm assuming the button is less sensitive than it should be so it works fine without the protector but not well with it. I might have to switch to a partial-screen protector.
So if my buttons are very difficult to press then its an issue and not the general design of the phone itself?
My wife said she has no problems with the buttons so I'm going to have to compare hers to mine.

Same exact situation. I was using the Realook screen protector and everything worked fine except for the back button. After I took it off I noticed that the back button worked just fine. After using it a little longer I still feel like it's not as responsive as the other three buttons.

There's a couple of ways you could do this:
Every time you press a capacitive button, it should blink right after it registers. This indicates it was pressed.
Another way is to boot into Clockwork Recovery Mode, goto Advanced, and use the key/button test option that's in there.
I'm also using a Realook screen protector, so far it's the best I've tried. I've used Zagg, Invisishield, StealthGuard, and Amzer protectors and non of them had the clarity or feel of the Realook. It feels and looks like nothing is there, aside from being an oil magnet. Anyhow, I don't have any reduced sensitivity when using it compared to bare.
One trick I use to apply the Realook is cover the whole phone with 4 or 5 strips of scotch tape (overlapping each other) before application, it helps to get rid of all the super fine dust particles that are floating around. Also, use a high power flashlight, and shine its beam across the surface of the screen, it will make all the dust you couldn't see before light up. Have a few looped pieces of scotch tape ready to pluck off dust particles that get stuck on the protector and screen. Then get the Realook protector ready, pull your strips of scotch tape as one from the top and quickly align the protector, pull more tape off and follow with the protector, this insures no dust thats floating around will get on your screen or protector, if some does, you have the flashlight to easily show you and the tape at the ready to pluck them off.
Reason I said the above is because you might have minute dust particles that are creating a gap with just enough space to prevent your capacitive buttons from registering.
I took drastic measures and cut a rectangle hole out of the Realook protector so I could have direct access to the buttons. It is ugly, but it works. The back button works much better now.

Mi 9T Proximity Sensor Issue

Is there anyone else encountering the same issue with me?
I realize my proximity was not working when the screen wont turn off during the call when using the earpiece. I did went into the CIT and performed the proximity sensor test and the proximity sensor seems not even reacting.
Is there any chances that it could be the tempered glass screen protector affecting the sensor to work normally? I found that the phone is eventually something they called it "Virtual Proximity Sensor" so i kinda clueless on fixing this.
Mine is working through the glass.
Apply all the updates, happened the same to me until i applied system updates.
The reason of it is you glass protection.
Works for me. Unless I am in another app whole in call
I face the same problem
The proximity sensor seems to be located on the top right (next to earpiece) literally invisible to at least my eyes. Make sure you have no bubbles in that area from screen protector install and if there's a smudge from your fingerprint it might block the sensor thinking it is placed near your ear. So clean it if it doesn't work properly. Maybe screen protectors with black borders like the Nillkin one require 100% accuracy when applying them?
I do have a line all the way around my phone where my screen protector has and will not stick to the phone.
Can't comment on plastic screen protectors.
I have the same issue on my MI9T Pro. Tested with CIT (4 times click on kernel version appear this tool to check the hardware). First time the sensor worked fine (5.0 to 0.0), second time it was stuck on 0.0
Then I reboot the phone and it has fixed by itself, but this is a recurrent issue, I couldn't solve. Someone knows the real solution?
I have the same problem , i don t know if is a software problem , i think is more a hardware problem . The sensor worked fine ( i think ) until i installed a temperd glass . When i put the glass " perfect " the sensor not worked ...then i moved the glass down , and is working , but not 100 % . In call i must find a position , an in my pocket not seek to work . I use a Wozinsky Super Tough for Xiaomi Mi 9T & Mi 9T Pro, Full Screen, Full Glue.
For me screen protection is very important , and i make thia compromise for now . I Hope to find a better temperd glass !
+1 for the proximity sensor problems... I had 10.3.15, now chaned over 10.3.11 and the same. I have screen protector from Samsung A50. Sensor is going off when I make a call, and didn't came back when I put the phone down.
This is not happening every time, but once in a day/two...
No problem in K20. Using back cover and .2mm plastic screen protector
I think the problem is with temperd glass , mine have black border and i think that is the problem !!
I have the same issue. But I noticed this only happens for the incoming calls and not for the outgoing also I noticed when this happen it's like sensor doesn't wakes up but I have to say that I have screen protector also. I read in a forum from Spain that several users have the same issue even without screen protector.
For the incoming calls, I notice a lot of times that the phone/smart watch is ringing, but the screen is not turning on. Even when I unlock the phone can see that someone is calling...
Screen protector
I have the same issue. I have a tempered glass with black frame too. The proximity sensor doesn't work when the glass is on. It is a really strange issue.
I have the same issue. I have a Xiaomi mi 9t pro and my proximity and light sensor don't work (same component)
But I have a theory. Like many I have installed a tempered glass previously but I removed it some weeks ago because of a crack. But I didn't replace it with a new one.
But who else used the (included) oil to remove the halo effect around the screen protector?
I used it but I think some oil seeped in the speaker grill and this maybe gives errors on the contacts of the proximity and light sensor!? The sensor is nearby the speaker grill.
I have the same problem... Have phone about a month, I've put glass the same day I bought the phone... Does anyone know where is the problem?
All i can tell you all is how to apply these screen protectors, because at the end of the day it is NOT a hardware issue. (sure, maybe a hardware flaw when using it with an accessory such as a protector)
The best method imo is to use tape or the sticky stickers that should come with the pack, so you end up creating a hinge that should always "close" at the same exact spot when you "open and close it".
Only then should you continue to peel of the film after thoroughly but gently wiping off the dust and marks especially near the proximity sensor. Make sure the phone is "naked" and that you do this in the least dusty environment. Do not waste any time after peeling off the sticker but do not rush and risk messing up the allignment. It should be an even gap/space all the way round of the phone. If you feel like you did everything right and it still doesn't work then next time move the screen protectors ever so slightly downwards.
Refer to my first post on the first page to see my phone's screen protector installed. Guess I can take some clearer pictures and show you. Have used the phone with three cases and zero problems apart from smudging the sensor with my ear a few times.
My first post using text formatting lol
I briefly had your issue, i simply cleaned the top speaker grill.
Can confirm, tampered glass with black borders cause this problem. I removed it and now it works flawlessly.
