Recently I added a screen protector to my Alpine, and after that the screen started acting funny any time it was left alone. Removing the screen protector has made no difference.
After a short while of not being used, the screen becomes misaligned, for example if I leave it off for an hour, attempting to activate the start menu on the today screen will result in one of the today items being pushed, or attempting to select a number on the password entry will result in a different number being pressed.
The strange thing is I can re-align the screen through the control panel, but it will slowly go back to the way it was.
Anyone got any thoughts? At worst, I'll just refund it (I bought it where I work, and thats no problem) and get another handset, but if theres a fix I'd prefer to stick with my current handset.
Cheers in advance for any help!
I am not sure about this, but I had the same problem with Motorola A1000 touch screen - could it be that an excessive pressure was applied to one of the sides of the digitizer during the application of screen protector? The digitizer is glued on the LCD, there might be a remote chance that it has slid a little to one side. Also some extra glue could have shortened the contacts on the bottom part of the digitizer. I would try to clean it first with some anti-static liquid. Hope this helps..
Indeed, this sounds like there could be more pressure to one side of the screen than the other, hence the digitiser tries to adjust for the pressure difference and gradually falls out of sync.
Try reapplying your screen protector, more gently than last time if possible, but don't wipe from side to side, wipe from top to bottom with an even pressure. Also, try realigning the screen with the protector off before reapplying it.
I had a problem with my screen originally before I got my screen protector, insofar as I got that 'rainbow' pooling effect in the centre of the screen where the digitiser was touching the LCD layer - after about a week after application of the screen protector, however, the more even layer of tension provided by the protector somehow pulled the digitiser away from the LCD layer, so my screen has actually gotten better since then... That said, I could imagine that uneven tension on the top layer could lift the LCD and digitiser layers further away from each other on one side than on the other, causing the problem you describe here. If you can bear to, try using the phone for a couple of days without the protective top layer applied, and see if the alignment gradually slips out as it's doing at the moment.
I've been using the phone for the past two days without the protective cover on. I'm going to reapply it now and then see how it goes tomorrow. If its still screwed, I'll reflash it to the O2 ROM and refund it at work on Tuesday.
Got a replacement, so no problem now. Thanks for the help anyhow
ok it doenst happen when i lay the phone down on the surface and click on the screen it works perfectly
however when i hold it with my right hand and touch the middle of the screen with my thumb
it opens up phone dialer, or appdrawer or vibrante cause it clicks the capacitive button.
when i hold it with my left hand it gets a little bit better but it still does.
if i hold the nexus carefully and touch the screen , it works, when i hold it like this
the things gets better when i put a thick case like otterbox..
is this a hardware issue? ( found similar video on youtube)
my phone is rooted but can i still get a replacement phone?( already put everything back to stock)
and if i do get a replacement, are they going to charge me with anything?
my current nexus one trackball doenst scroll up but everything else works.
How many of you guys got a replacement even though your phone was rooted?
Make sure part of your hand doesn't touch the screen.

it's a hardware issue...
all you can do is not grip the phone too closely to the edge of the screen. It registers touches even if you are not touching the screen completely. But that to be a problem you have to have giant hands
I've had this happen to me once since I had it from launch day. It did happen with my Otterbox commuter series, and a clarivue screen protector. But I turned it off and on again and it was fine.
anyway as stevio jobsio whould say, you're holding it wrong

ok so it is a hardware issue?
no i am not touching any part of the screen. i made sure i wasnt touching the screen.
but it does happen when i hold my phone closely to the edges.
i never had this kind of issues with other touch screen phones..
Well I dunno... One finger at a time and your good to go unless you got fat hands lol

I can confirm that my device too does this. When lying in bed I browse the net with one hand and try and scroll....the edges of the touchscreen seem to register depression when the chassis is pushed or gripped too hard also.
It's a minor irritation to me, but I agree it is a hardware issue.
I only got this phone couple of days back and I am having a strange problem.
After installing a screen guard, touch stops working when phone is lying on flat surface. Once I lift the phone, touch starts working again. This happens regardless of the phone is plugged or not in a power socket.
Removing screen guard resolves this issue. However, I installed three different screen guards of glass, plastic and rubber types and with each type touch stops working on a flat surface.
I also did a factory reset but it didn't help. I tried with case on and off but the problem still persists.
At this point I am clueless how to resolve this issue as the phone doesn't seem to be defective as touch works flawlessly without a screen guard.
Same here!
With glass screen protector I have this issue... Can't really use it while device lying on a table.
Hi... Same here also... I thought the screen problem but not even lying on the table but when in charging lying on the table also can't touch... And sometimes it's stuck when to touch... My nokia 6 i think also like that... Maybe the screen curve is??
I have screen protector bought from Taobao, no such problem on my Nokia 8, TA-1004.
The screen protector is not glass type, but looks like plastic type.
Another strange observation: If I plug headphone jack when the phone is lying on flat surface, touch starts working again.
I suspect this entire thing has to do with metal/glass body of the phone and static electricity generated or magnetic field around touch panel.
I don't have much knowledge on this type of scientific stuff so I am not sure what the problem is.
It's the cheap glass protector and its glue that is messing up the touch screen.

I thought so. But what about headphone jack fixing touch issues with screen protector on?
Also, I have used similar quality screen guards on Moto and Huawei phones at my home and they don't have this issue.

Are you connecting it to headphones or speakers?
Maybe the capacitive buttons doesn't like the glue and messes up everything? You could try enabling these in the Developer Options: Show taps & Pointer location. Let me know what is happening

Headphones.
Enabled taps and pointer location. When phone is not touching a flat surface everything works fine. A curve is drawn on screen showing various gestures and a circle is drawn to show taps.
When lying on flat surface, if I use any touch gestures (e.g. scrolling) curve is drawn once in 5-6 attempts. Same with taps, circles appear only once in a while.
It is all very erratic. When I repeatedely try to tap anything, I receive ghost touces at a different part of screen.
Just noticed that I don't need headphone jack to fix touch. Blocking 3.5 mm port with one finger also works. This is truly getting weird.
Have you shown it to the Service Centre? Do they have any theories?
Sent from my Pixel 2 XL using XDA-Developers Legacy app
No, since the phone works perfectly without screen guard, I think service center guys will simply tell me to use it without a screen guard.
But I will indeed show them this problem after few days, though I am not sure they will understand or will be helpful in this regard.
I think I am reaching somewhere. The antenna reception at the top might be messing with touch.
What I have observed that touching the top of the phone or keeping any object or my hand one inch away from top of the phone fixes touch issues.
If I remove the object or move it farther than one inch, touch becomes messy again.
If I put little pressure on bottom chin of the phone, the top of the phone raises a bit so that the top antenna is not close to flat surface any more. This also fixes touch issues. Lowering top part of the phone brings back touch issues.
Anyone else with this issue can test this?
This video exactly describes my issue:
I found that many phones had these issues in past including oneplus, lg, sony and galaxy phones. Everywhere it was mentioned that it is a grounding issue which is unfortunately a hardware detect.
My phone is fortunately within replacement window. So I will contact the seller and request for a replacement.
I was thinking about the grounding, but when you mentioned you used headphones i thought it couldn't be the case.
Keep us updated if you get it replaced.
Just received the replacement. Same problem on the new one
I don't know what to do now. No other phones in my family have this problem and that includes $200 budget devices. This is flagship and much more costly.
I will just summarize different cases in which the touch issues on a flat surface gets fixed on my device:
- Inserting headphone jack (with screen gaurd applied on display).
- Inserting charging cable (with screen guard applied on display).
- Touching any part of the phone with finger including blocking the headphone jack (with screen guard applied).
- Removing the screen guard.
I am tired of this sh*t. I have tried all things possible to fix it. I have also wasted money on 6 different screen guards to fix this issue.
Some guys on galaxy s8 forums mentioned that modern curved phones uses a touchscreen placement mechanism different than traditional smartphones (they were also having the same problem).
There were two possible solutions mentioned:
Find a screen guard that has glue all over, not just around the edges or at dots. Which means that screen guard should stick to the screen 100% flat without any gap, air or bubbles.
Second solution was to use a flip cover to protect the screen and no screen guard.
I will go with second solution and buy a flip cover. I simply have no energy left to hunt for screen guards that work properly on Nokia 8. Not to say that you will never know if it works or not unless you purchase it and stick on your phone.
Hi, I'm writing from Italy and I've the same problem, exactly the same problem, solvable with the same solutions you have proposed: remove the protective film (a glass screen guard in my case).
I'm noticing that the touch screen works perfectly with the protective film only if the phone is connected via USB cable to the battery charger or to the pc.
My S-Pen is over sensitive. It activates when it's very close to the screen or when I barely touch the screen briefly. Very annoying. I have a tempered glass screen protector but still it's over sensitive. I have seen many solutions to increase sensitivity, but not to decrease it. Is there solution for this?
Did you increase the sensitivity because of the screen protector? Is is better, for spen at least, if the sensitivity is on default setting?
Define, "activates." What does it do?
With default settings, and a glass screen protector, my phone recognizes the S Pen when it is within 12mm - about 1/2 inch - from the screen. That's when the little circle appears, and the Air Command button highlights (for example). I rather think it's supposed to work like that. You shouldn't need to touch the pen to the screen or apps like Glance wouldn't work.
The s-pen detects pressure by sensing how hard the nib is pressed, thus the phone can recognise by determining where the pen is on the screen and the pressure exerted (you can test this by pressing the nib with your finger, and hover your s-pen on something you want to click)
You could try removing the nib and re-inserting it back, if that helps

By activate, I mean it will launch apps on the home screen, open links in by web browser, etc. I get the little circle when my S-Pen is close to the screen and it works as it should. That's not the problem.

I tried replacing the nib, but it makes no difference. I have a second S-Pen that came with the phone and it does the same thing. So, I don't think it's the S-Pen that is the problem, it's the sensitivity of the screen.
I recently purchased a Tab S8 Ultra and it's been great so far. However, I noticed that the S Pen doesn't work consistently at the edges of the tablet, particularly the 'bottom' edge where the keyboard connector is.
I initially observed this when I tried to click the 'home' navigation button with the pen, but the click would not register. Repeated attempts to click were met with failed responses more often than registered clicks. This was with the tablet in landscape mode and the taskbar enabled - so the navigation buttons were concentrated at the bottom right of the screen. With the tablet rotated to portrait mode, however, the buttons were responsive and worked as expected. I tested this in Samsung Notes as well. It seems to be common for small 'dead spots' to appear when drawing along the edge. The thing is, when making a pass back towards those spots, they can sometimes be drawn over. These spots are generally in the same area, but the pens' ability to function over these regions seems random. See examples.
I assume this has to do with the magnets around the sides of the tablet interfering with the display/pen EMR technology, but it's odd that it is inconsistent. If the tablet is using permanent magnets at the bottom, one would expect the effects of their magnetic field to be present at all times. It would also be a pretty major design flaw if the pen doesn't consistently work with the navigation buttons in one of their default locations as well.
Has anyone noticed similar behavior with their S8 Ultra (or any S8 series tablet for that matter)? Do you think I have a defective unit?
Make sure you have not turned on disable gestures and buttons when using s pen. That will make so when you use s pen the home button and such won't take affect when touching them with the pen. So no it has nothing to do with magnets for keyboard. Since i tried now with my s pen and it's registering fine.
Hello
Im facing the same issue infact my s pen doesn't work properly in the middle of the screen also. If i press it too hard then it seems to work fine. It started happening a month ago can someone please suggest what i should do ?
Also if it take it to the service center will they replace the device ?

I have the exact same problem + it also happpes in the top edge not just the bottom ,,
As you said home button doesn't work with s pen but other buttons ( back , recent , screenshot , power off ) works instantly without any miss , which is weird
But in other scenarios , not home screen , like photopea.com ; the "adding layer" button ( which is at the bottom edge almost at the same place of home button ) doesn't work with s pen
Another example; in adobe lightroom the top edge have the same problem, it doesn't respond when tapping ir drawing on it , but it Does when starting the drawing in a closer area from the middle then moving the s pen to the edge , in this case it works , which is very weird

If your issues are to the right of the front-facing camera, maybe they have to do with the S Pen magnets?
I ultimately decided to exchange the tablet. My new one doesn't have any of my aforementioned problems. Also, the issues had nothing to do with the gestures option - the dead spots existed with gestures on/off.
Although the issue is solved, the root cause is still unknown. I'm starting to consider if the problems I had were due to a case. For a short period of time I had a Speck Balance Folio on my first Tab S8 Ultra. It was a nice case but I had to remove it after the first day because the cases magnets were creating huge dead spots on the screen. The case had a pretty large magnet spanning the lower half of the tablet, so maybe it was strong enough to permanently alter the in-built tablet magnets? I never drew on the edges of the screen until after I removed the case, so there was no way to know if the issue existed beforehand.
I currently have the official Samsung Protective Standing cover on my new tablet, and while it does have two small magnets near the edges, I have no issues using any part of the screen with the S Pen.
I guess to answer my own question in the post, and to possibly help anyone reading this in the future:
Your tablet should not be having issues near the edges of the screen.
Avoid all third party cases if possible, unless they are confirmed to be magnet-free (e.g. Supcase Unicorn Beetle and Poetic Turtleskin - It's a shame there are no magnet-free folio cases with decent protection).

The problem ( in lightroom ) happens in the left side of the cameras
I have the official Samsung bookcover keyboard , i removed it but the home button stil didn't respond , then i thought what will happen if i try from a different angle ? And that's what i did , i used the s pen as its top is heading to the cameras not to my side , and it worked ! Home button responded in every single try ,,,, then i placed back the kickstand piece of the bookcover and did the same with the s pen , and it also worked with no miss , so i think it's not the magnets' fault , it's something in the angle of the pen ,,,, note that i tried the normal way of using it ( when the top of the s pen is heading to me ) and rotate it many times and touch the home button , didn't work , so this probably confirms that it's a matter of angle detection not dead spots or magnet thing
Also , the top left edge responded when swiping down to bring the quick setting , so maybe lightroom app is programmed to not detect the edge's touch in order to prevent any accident touching when handing the device
So i guess there're no big concerns here , we can live with that
Generally speaking, Samsung tablets have always had issues with covers that use magnets to hold the flap closed against the screen as they are too strong for the inbuilt algorithms to compensate for. The Spen itself is nothing but a magnet whose movement is detected by these algorithms. The magnet flaps interfere with that.
I have had ZERO issues since I switched to a cover that uses an elastic band to hold the flap closed against the screen. It has magnets, sure, but they're tiny and only for the lock/unlock functionality, not to physically hold the flap against the screen.
Hope this helps!
