No matter what I do and however many times I flash cm7, I seem to have erratic touchscreen behavior.
The nook is BRAND NEW (two days) and I flashed it with cm7 7.0.2 stable (after phiremod's 6.0 & 6.1) and flashed it about four times now.
I have tried it with the OC and without.
It's not the SD - it doesn't matter if it's in or not.
Not the wifi, since I didn't even set it up the third and fourth time - it was too erratic to even try.
Plugged in or not... still the same problem. Doesn't seem similar to the other forums topics about touchscreen issues WHILE charging.
Screen is near spotless... no smudges.
It is important to note, that it waits until I have done a few things to start going crazy. I restart it and it's fine, until I do some cpu intensive stuff - live wallpaper is the simplest activity that causes it.
Any ideas?
I have also tried NSR (screen re calibrator) to no avail.
Would love a quick fix rather than re-installing stock and returning it and convincing them to replace it. I am not sure if it does it with stock... didn't wait long enough to find out before flashing it.
have you tried a screen protector? my screen wasnt the best for precise touches but since i put a screen protector on and clean the screen regularly it has since changed my problems to almost non existant.

Others may be able to help you more than I can with exactly when the CM7 may be doing this, but returning to stock to find out is actually not hard at all.
In the development thread there is a post that has the 1.2 stock zips (one keeps CW in place, the other returns it completely to stock). Which ever one you pick it's still just as easy to return to stock as to reflash CM7 again. This is especially true if you used a SD card with CW to flash (which is what I do), since when you want to go back to CM7 you won't have to worry about flashing CW to emmc again.

Hate to say it but it sounds like it might turn out to be a hardware issue. This is not a CM7 issues that I've seen from anybody.
Can you describe the behavior in more detail?

It seems to start selecting things on its own after I have been using it for a while. It's difficult to describe except that there isn't really a pattern... it selects something different and keeps at it. At one point I almost purchased an app from the market before I had to power down.
I will return it to 1.2 stock and report back. I was mainly wanting to know if these was a commonly reported issue or not. I guess it's not. Thanks for the help everyone!

So my NC started to do the same thing last night. I have been running CM7 (at 7.0.2 now, but nightlies before then with dal's OC kernal) for quite a while now with no problems. Only thing I did last night was to delete about 1GB of ebooks off of my NC and reload them through Calibre.
I left it alone last night after it started doing it and then this morning it started doing crazy touches again. I was in Aldiko and it was selecting books and turning pages at random. Rebooted and it seems to be fine for now. Little odd though considering it has been running perfect for a few months.

So now I have installed nook stock 1.2 and NO PROBLEMS. I have run everything trying to get something to happen, and nothing.
Is it possible that I installed something the wrong way with cm7? Could I have used the wrong CWM version (3.0.0.6)?
Should I try cm7 7.0.2 or something else again?
I would try and return it, but I can't recreate the problem... if I could, I would be in their face right now.
Thanks for the help so far.
I think I solved it!
The newest nooks (in the last week or so) have 1.1.0 factory stock. Apparently there is a glitch that has been reported a lot recently about handling the touchscreen AND the SD card. These were fixed in the 1.2 upgrade. SO...
1. I flashed factory stock back on (in this case I went back to 1.0.1)
2. Then turned it off and "restored factory" settings using "Power+N" to turn it on. Repeated that a second time to get B&N's factory reset screen to come up.
3. Pressed N twice to accept restore prompts.
4. Upgraded to 1.2 (no glitches already by this point with touch or SD)
5. Booted CWM 3.0.0.6+
6. Formatted /system & /data
7. Flashed phiremod 6.1
8. OC'd to 1.1Ghz
...and DONE. No problems so far. I still see the "Read Forever" opening screen, but it still works wonders. WAY better than before.
I am still having issues with Wifi, but I can deal with that.
Now to attempt dalingrin's OC to 1.3!
Thanks guys... hope this helps others.
I think they call it "Touchscreen goshting". It started happening to me when I rooted the nook and the keyboard would go crazy. Now in CM7 7.0.2 with latest kernel, it happens more frequently. About 5 minutes in from boot, fast random touches occur. Most of the times this gets fixed by pressing the power button to turn the screen off (sleep), and on again. I guess it could be a hardware issue where some devices are affected. I haven't tried any recalibration apps to try to fix it yet, its kind of annoying when it happens in fast intervals.
I had weird touchscreen issues when using the interactive cpu governor. I later found only performance is supported. Using performance setting, everything works much better.

I had the same issue. I exchanged it the other night and now my new one does not have the problem. It probably a hardware issue...i hope you are still under warranty!
hi guys,
can somebody please help me, since couple of days my Milestone is behaving in a erratic fashion. it automatically opens apps, closes it, disable my capacitive buttons, and many more like this. i was running on stock 2.2 with root. it worked good for 20 days, suddenly it started behaving this way. i flashed it to stock 2.1 and applied cynogen 7.1 (latest version), but the problem still exists. not been able to use my phone.
Guys help me please, really scared, feels like my phone is haunted
Looks like your digitizer is going to die... its a common problem in MS1.
Its like some one is touching your screen... phone goes mad.
Look further in this forum and you may find attemps to fix it (or at least a try)
Good luck.

So I started noticing lag on games with a virtual pad. As in, jump works fine if im standing in game for example, but im running and I try to jump, either it doesnt do it at all, or it does it with some lag.
So I downloaded a multitouch tester and pretty much confirmed that there's an issue there.
If I just touch with one finger at a time, it works fine. If I press with two fingers and keep them there moving them around and whatnot, it also works fine.
BUT, if I keep pressing with one finger and use the other one to do a fast light tap, half of the time it doesnt register it.
Im using the ROM posted here: http://forum.xda-developers.com/showthread.php?t=1583871
wich im finding to be great, but I thought of originally posting my issue there since I gather it is more likely to be caused by software and not hardware.. right? considering simple touch works completely fine.
Any ideas?
Ace supports only 2 fingers at a time. But i did not find any types of lags while using 2 fingers. But it wont work if u use 3 or more fingers at once.
REPLY
Hey I got 100% same issue too. On original cm7 nightly.
But I found out sometimes it works and sometime it doesn't seems to work. I think it's similar to the rounding bug.
Maybe it's the kernel problem. Just don't overclock and it will work well. Or, reboot your phone and wait for a night without touching it, and the problem is gone. However, the bug will occur again after you install an app or launch an app. This multi-touch bug always occur on cm7. If you don't want this problem you can use stock roms. But if you say touch making it lags, it doesn't make our phone lags or the game you play using this phone is a bit slow. Just the second finger is responding slowly if the first finger is pressed/touched on the screen.
And I've tested this bug using the dev tools in the cm7 rom. dev tools/pointer location. All of the stock rom doesn't have this bug except cm7. CM7 will not have this problem on the first few weeks since the first boot. hope it helps
It's a Ace Hardware issue. Nothing to do about it.

Hi everyone,
I bought a Samsung galaxy s last week from an eBay auction. The phone was described as touch screen lag. I was thinking that flashing a new firmware will solve the problem. I got really cheap though
The touch screen stops suddenly in every 5/6 minutes and I have to lock the screen using power key and unlock again to make it working.
when I got the phone:
Non Samsung battery and chargers were used, I changed and using original ones.
Stock XXJVS firmware in it.
First I flashed stock 2.2.1 froyo and test the screen using *#0*# code. it got pass. But when I start using it, the problem was still there.
Then I flashed stock GB, same story, now slim ics, same thing.
Please someone help me, there is nothing I can do with it now.
I search few threads related to screen problem but couldn't find one with similar problem. So asking here.

Sounds like a hardware problem to me..but it's really hard to say if it is. But it would definitely seem like it since it isn't ROM related. Maybe a water damage or faulty digitizer?

This happens to me sometimes very rarely though, it will be weird and hard to touch but speaking to someone with the same phone they said they had this problem to all I do to resolve the problem is lock and unlock the screen, I thought this was normal?

It shouldn't be normal. I am using another galaxy s for almost two years. But never had this problem in such extent, little bit lag on touchscreen when on froyo. But never after. Now with slim ics Temple run is more smooth then iphone 4.

Thanks for reply. When I got it first time, it was really annoying, the problem was so frequent that it was almost unusable. Now in new rom, after unlocking the screen it works little longer then before. Works like a charm when it works. So not sure this is hardware problem.
Sent from my Galaxy S using xda premium
I don't think this is a hardware or problem either, I broke the screen and replaced it and I still have the same thing when though it is very rare, so if it was the screen it should of gone after I installed the new one, btw I installed a whole new pre built front so the bevil and LCD, and my phone has never hib water damaged? Maybe its something to do with the bootloader? As that doesn't change through ROM flashes

@xsenman;
I did that couple of times going through Advance slim setting. That didn't change anything. Now I'll try this as well.
I change touchscreen into chainfire sensitive option in semaphore app. Still lagging.
Tried over clocking to 1200 but it freezes and automatically reboots into recovery mode. I can use only after changing to default

Guys its really annoying now. Its behaving strangely. I played with it few hours and found out that the screen near the home button freezes first. I cant press the dock but still pull the notification bar? then stops working whole screen. I checked the show touches in developers options setting. Sometimes it works randomly actually without touching it , I just place my finger near the screen but didn't touch and on few occasion it works opposite direction, like I scrolled down but it gone up:crying:
Is this the sensor issue? Is there any way to fix? Any idea please?

Screen+digitizer panel can be changed by yourself. For it, you just need couple of tools and little nerves
Instructions can be found from YouTube, this forum and many other places..

I tried all of those apps, nothing wrong. I think I should change the screen and digitizer, I might need to go to the repair center because my hands shake (my usual problem) and hard to fix tiny things. I want to do few experiments before taking it to repair. I already put it in the freezer for two hours it was acting like crazy after.
Suggest me more...

Me too!
and i thought i'm the only one experiencing this kind of problem. it is exactly what i'm having on my sgs. seems to be temporarily fixed by turning the screen off and then on again, but after a while, the screen doesn't respond on the same spot as you're having.
i've managed a low level debug on screen touch response using adb logcat, and my touch doesn't really register any on adb logcat console.
they might be correct on the hardware problem, but when i'm on any gingerbread rom (2.3.6), the problem is gone.
guys, any idea what kind of drivers they're using on gingerbread for our touchscreen?
I have this too on ics, left half of screen stops responding, lock on/off sorts it....until the next time! Bugs the hell out of me!
Me too! on ICS
btw, i'm already on ics team nyx
change
flash CF KERNEL and put ICS CM9
middle screen not responding
- when in stock gb firmware (official from samsung), the touchscreen problem is gone.
- but i want the features of an ics rom, so i flashed one (first was slim ics); the problem appeared first; first guess was the custom rom was still in its early stages.
- flashed back to gb, no touchscreen problem.
- flashed new ics rom from cm9 (nightlies), problem appears again (ugh!).
- flashed backed to updated slim ics since this was the fastest and easiest to install, touchscreen problem still persist.
- found a temporary fix by turning the screen off then on again.
did a adb logcat full trace log of touchscreen input: what i noticed was the whole vertical middle part of the screen is not responding to touch; dragging touch from one side to middle is working just fine, but not starting from the mid vertical part.
the problem may sometimes go away after a while, and sometimes persist even after the temp fix. it's very intermittent indeed.
help please.

So your sgs touchscreen working fine on stock gb rom! It might not be a hardware problem then. We have similar problem, only difference is I have problem on GB too. I've even tried stock froyo, same story

same problem here, left part of the screen would be unresponsive at times
can fix by locking the phone through power button and unlocking it, thats why i think its a software problem.
I dont remember having this problem in GB also.
maybe something is messed up during flash?
I have the same problem with ics and jb roms from the onecosmic ics times and i had a topic http://forum.xda-developers.com/showthread.php?t=1648287
I have written here but no one seems to now what it is, i have been using ics from onecosmics first release and had the problem from that moment on, different kernels, roms etc it is still here i have flashed gb again and problem is gone, flash again with ics the middle part still acts sometimes. ?...
We should request from kernel developers and rom developers to look into it. I have tried almost everything no luck so far
