I have experienced a really strange phenomenon. Just got a new Galaxy S GT-I9000 and decided to give CM10 a shot.
The main problem I am facing is some sort of a lag or better no response at all randomly. Problems are visible when:
1. I type on my keyboard
2. I scroll down long lists
The Problem.
Sometimes the device doesnt respond to my "tap" at all. The bug just occurs on the right half of the keyboard so you could say lower right half of the screen in a certain area around [k, i, l , j] buttons. When scrolling down lists my thumb is normally in that area so even when scrolling down the screen simply does not react from time to time and when I lift my thumb up and tap again everything works as normal.
This problem is extremely frustrating because I am not able to type properly anymore. First i was afraid its not the Firmware BUT my phone. But on stock rom I dont experience any of this at all.
Does anyone have an idea? Why can't I find something about this problem in the Forums. CM9 should be stable and nobody seems to experience this problem but doesnt the fact that it works on a stock rom prove, that its can't be the hardware?
Greetings

Is there any programme to for screen calibration? So part of the screen seems not responsive.
That is a hardware issue not a Calabration issue..
does somebody know if this "hardware issue" is present at all note's?
i found that my screen is a bit unresponsive at the top right corner. i cant draw about 2mm to the border of the screen (with the pen)!

However when I flash a new rom the screen get responsive for a short while. After that I need to press the screen harder. On the bottom right hand corner has this problem.

Did you ever solve this problem? Mine started doing it after it updated KL7 OTA.
Well guys I'd like for someone to chime in on this. I thought for sure this was a hardware issue. I'm on my second note now. My first note seemed like it was having issues with the lower right corner of the touch screen. I thought maybe it was a rom issue. I flashed clean KL7 and it seemed to suddenly be better then after a little bit it got worse. I have my second note and I flashed KL7 right away on it. Now after a little bit it seems to be getting less responsive, still better than my first, but I'm beginning to think this is a software issue. Any of you having these issues what Rom are you on? Should I try changing out this note for a third and see what happens? I may flash to some other firmwares to see too.
my top right is a bit unresponsive as well. . it works but seems a bit off. .
I used swipepad , really useful taskswitcher
It does not work when phone is connected any charger.
I've definitely noticed the phone being less responsive when on the charger, but this seems to lose responsiveness over time off charger and on battery.
I've had other phones that from time to time would act a little wonky when using them while charging.
Hey,
I've had some display problems, both with regards to calibration and also when it's charging.
I have made this video to demonstrate a problem I have of calibration. Watch how the display detects a signal at a point offset from where I press with the pen.
For me the problem I saw using the *#*#2664#*#* test is that the last 10 pixels or so on the 2 end sides of the screen don't respond.
For the pen offset is cause of the left or right handed settings, I find that holding the pen and rotating it so that my thumb presses the button of the pen instead of the indicator finger gives pretty good accurate results.
I'm definitely thinking this is at least more software related than hardware. I don't remember noticing any problems when on KJ1 or KK1. So I flashed back to KK1. It started it up and then I did a quick factory reset. This is completely stock/unrooted. Anyway bottom right corner seems to be having no problems detecting my touch now. I'll leave it on this for a few days and play around and see if it seems to lose sensitivity again. If it does I'll let you guys know, but for this to be a hardware problem I can't imagine it being this intermittent. Any of you on KL7 that mentioned this issue, are you guys completely stock KL7 or using the CF-Root Kernel? I know someone mentioned losing functionality in music player and torch and it seemed to be an issue with an alternate kernel.

That´s normal - pen is calibrated to use it at a certain angle - try to change the setup from right handed to left handed and you will see a different offset if you make the same test again.
The offset should be the same on each area. Only if this is not the case i would say, there is an issue with the screen.
Hey, ok so it is a deliberate software decision. Kinda sucks- I'd think I'd sooner like to have it type directly below where I write. I'm guessing it is an attempt to account for the fact that the glass has a finite thickness. Sooooo does anybody fancy writing a kernel alteration for this...?
i also find it more annoying than useful
Couple days on KK1 and what I thought was a hardware problem still seems to be fine. It's detecting much better in the bottom right corner where I was having issues on KL7.
I am having the same issue with the reduced responsiveness of the bottom right corner. I've noticed it after updating to KL7. Maybe is the driver of the screen.
Is there any way we could report this back to Samsung?

Hello.
I have the same problem ate bottom right side of the screen. I am ate LA4.
what should I do?
Although the problem was nearly imperceptible some days ago, while the note was connected to the charger, I've noted a very small area near the bottom right side of the screen where it was difficult to write using the stylus with SMemo. On the opposite side the loudspeaker is present; and so I've thought it might be correlated with the magnetic field of the loudspeaker. Today I've performed the *#*#2664#*#* test with and withouth the charger, but the problem is not occurred. Because of these devices are always more complex I prefer snap closures for my cases.
I recently got a replacement phone from esurance for a broken Droid x2. They sent me a droid 4, which I had no objections against given the great specs comparatively.
I read reviews on the screen being low quality, viewing wise, and this is not the issue I have with the phone. Coming from a dx2, the quality is not that different.
My problem is that there appears to be a lag between when i touch the screen and when it starts reading the input. A simple test to show what I am talking about is as follows;
Download multi touch paint or another paint app. If I swipe my finger across the screen as fast as i can, I can get 2/3 of the way across the screen before it draws anything.
This half second delay makes typing on the screen nearly impossible...It only picks up about half of the letters I press when typing normally like I would on a Dx2. To be clear, its not inputing the wrong letters because i am not used to the phone.. Its not inputting anything on about half of my keypresses.
I am on the latest official (nonleaked) version of android. Unrooted.
Should I RMA it again? Is there a fix, and has anyone else experienced it?
Thanks for any help!
over 150 views and no reply yet? I dont mean to rush things along, I just wanna make sure i did everything right.. Im in the right section?
If nothing else, could someone else tell me whether they have similar results?
Is typing horrible for everyone on the onscreen keyboard?
I don't use the on screen keyboard much but the few times I have I have not noticed any lag. Sounds like a hardware issue to me.
I'd do a factory reset (yeah yeah, I know). If that doesn't fix it, you can either RMA it again or try to install a 3rd party rom and see if that helps things.
What you are describing is definitely not normal.
Factory reset actually cleared up my issues =) thanks!
Folks,
unsure what might be causing this: I am rather frequently experiencing ghost swipes and ghost input on my Optimus 4X HD. Right now I am back to cm11 nightlies and see this behaviour same as on the stock ROM or any other ROM I tried so far. Behaviour's all the same: At some point the phone will start responding to phantom input - randomly starting applications from the launcher, randomly entering text in case I am in writing a message, randomly scrolling up or down in the current application, randomly opening and pinch-zooming-in-out pictures, ... . Usually, powering screen off and on again two or three times resolves this, but it's kinda annoying especially in situations in which the phone starts randomly making calls...
Any idea what could be causing this? Hardware issue? Defect? Dirty display? Issues with using a screen protection foil? Any input or feedback greatly appreciated.
Cheers and thanks,
Kristian
Not sure whether _anyone_ else does experience this on this device. My insights, so far, is that ghost swipes and this kind of input issues seem to be shared by other users on other devices, too, but they don't seem to appear on all devices of a certain kind running a certain piece of software. As far as I am concerned, these issues still happen then and now - but considerably less often after upgrading my p880 to another ROM (using EuphoriaOS 5.1 unofficial instead of nightly CM builds now). So if you see this problem on a p880, maybe this might help you too.
I'm facing a very annoying problem in my k3 note, that some areas of screen randomly stop responding. In my phone its mostly limited to bottom right part of my screen where backspace on keyboard is located. Rest of phone is responsive except this region. Restarting the phone fixes it temporarily.
But strange part is it doesn't happen on all ROMs, I first noticed it in some AOSP MM ROM, then i think it was Andronium VUI ROM (based on dev 1628) and now on s433 rom which leads to believe its some software thing not hardware thing.
Are there others also which face similar issue ? Any possible solution except switching to different rom ?

Yes, I have this problem with the screen also. I've heard from others with similar issues on other forums. It seems it is a hardware fault or possibly an issue with the way software interacts with the screen controller. In my case the screen is periodically unresponsive around the letter E or R on the keyboard and I have to tap the area with greater pressure. Sometimes it gets very buggy and very frustrating.
There is another possibly related problem when scrolling a web page or dragging - larger areas of the screen become unresponsive. Turning the screen off and then back on fixes the problem for the next 2 or 3 minutes. This issue has also been fixed for me with the kernel from daniel_hk here http://forum.xda-developers.com/k3-...rnel-dc-mtk-m1-kernel-vibeuiv3-51631-t3483573 - the only proviso is you apply it to Vibeui 1631. So while the scrolling issue seems to be fixed, the unresponsive areas around letters E and R on the keyboard remain.
I've noted the problems above would temporarily go away after flashing a new ROM however they eventually return. I've considered buying a new screen but not really sure if its a hardware or software issue - possibly both!

hmmm it's interesting that different people have different areas of unresponsive screen. It seems more like software issue to me, as I started noticing this issue more on newer dev roms only. Today, I've reverted to dev ui 3.1 1622st as I remembered it didn't have it. Will report in couple of days of how it goes, so far haven't noticed it.
I have been facing touch problems for quite some time on the ROW version of the ROM s433. The touch starts acting weirdly, i.e random things start getting touched automatically and this happens mostly in the lower half of the screen. I turned on the show pointer location option from developer settings and it shows the pointer stuck at one point on the screen showing erratic behaviour. Turning the screen off and then back on solves the problem but very temporarily. Restarting solves for a longer time but the problem pops back up.
Okay so I wanted feedback regarding this whether someone else is experiencing this or not.
I have gradually observed during the last few days that a lot of my touches to click have gone unresponsive in Nougat. Initially it was something that I hadnt quite noticed but slowly the trend became obvious. Now dont get me wrong, this would happen a few times here and there with lollipop and MM as well, but the rate is far higher now on Nougat. Especially when typing on the keyboard this means mis-spelled words, missed letters, and accuracy is far worse now.
Has anyone else observed this or is it just me?
Just got my xcover 4 with nougat installed i have the same issue.
The sensitivity is low and i need to press a bit higher finger force to respond.
Even with sensitivity (glove mode) set to on things get worse.
I'm seeing the same thing. What is strange is that I'll see the button highlight/depress, but no action occurs. This is on multiple apps.
On what device/OS?
Sprint Note 5 on Nougat
Did you try gloves mode? Does it work?
the same for me on 920cd and the same iusse using S pen
I contacted samsung Greece about the existing problem.
I reported the problems me and you guys have and the tech support told me that your problems exist because you did not factory reset the devices before upgrading to nougat.
Anyone tried to contact samsung about the problem?
They dont know anything about it.
facing same issue screen lagging in note 5 sm-n920s also tried custom rom but still lagging in typing and scrolling on facebook
I have the same problem on my xcover 4 here!!
When I run the the touch screen test, touch screen responds well, but when I want to write a message or to scroll the home screen Its very annoying. It looks like software problem.
please help
Hi guys.
I have 2nd piece of Xcover 4 SM-G390F (first was change by seller for new one) and had the same problem. First 2-3 days all work perfect.. I have installed my applications, work perfect for two days, but after this... --After wake, display react only in centre area, 1 centimeter from display border no reaction or react on xxx touch. After few seconds (20-30) display react on full range, but with lags... So... I go for support to Samsung official at CZE.
Support tells me, that they don't know about this problem, that I'm 1st who has this problem... And some other bull... about unofficial sell and any other. So I post them IMEI and they let me know, if my distribution is official or not, and we'll see what next. They recomend me to go to service center, where somebody looks on my SM. So I see tomorrow.
