What's up with this? I noticed it first in GingerDX and Doixnah confirmed it himself, but it is not a rom bug, as it also happens in MiniCM.
In my case I have a Cypress digitizer and the screen is not sensitive on the bottom pixels and on the right border pixels. Very annoying for typing spaces and the letter P, for example.
I have the same problem with my phone...I also have cypress digitizer...
The digitizer causes the problem because synaptics users doesn't have this problem.
I do not think that doixanh or other develop able to fix this bug becaus he don't have cypress...
AndyX has cypress digitizer,
but I don't think that's fixable...
it's hardware problem, not software...
its issue don't available on CM6 rom's and on some app its issuen don't available(like Xda android app(if you move your finger from phisycal keybord to up than scrolling works))
and i know AndyX have cypress....
I have this problem in all ROMs..Even in stock!

Basically my phone sometimes recognizes my finger at the bottom of the screen and sometimes not...
It depends on how dry are my fingers.
I noticed a strange thing in launcher pro.
If you swipe from right to left, the screen is not reacting to it, ok. But try it when you set 3 homepages in LP and you are on the last screen! Strangely it works then, you can "overpull" the page easily.
Now this is some strange sh*t :-S

How about changing fling speed in LP options? It might help.
On the other hand, that's the way that Launcher Pro is designed...to be smooth and you don't have to swype from one edge to an another to change screen
Peace, DDI!
hmm in my case this didn't happen in pre-CM7 roms
Had the same problem with my digitizer. Just put in a replacement off eBay and works fine now.

You don't understand. I wrote this because in some case the screen edge is responsive, else it doesn't. So I think this is not hardware related problem. I just mentioned this because it is a strange thing about 2.3 ROMs VS cypress.
Sent from my E15i using XDA App
It isn't a hardware problem, so replacing the digitizer is nonsense.
Definitely, it's not hardware problem.
Just try to rotate screen for 180 degrees (must check 180 in accelerometer settings) and You will see that edge next to the Sonyericsoon logo will become the problematic one. And The edge with buttons will work perfectly.
I have cypress, too and this problem exist only in CM7 roms, on all CM6 rom there is no such issues with screen.
Also, I noticed that this bug doesn't appear in some apps. Also in settings, screen work perfectly.

Nice findings, pal.
i don't have any problem with this in any rom. All screen is sensitive with all roms i've used, GingerDX, KuyaDROID, MiniCM7, MiniCM6, FroyoBread, Floyo, GingerCruzt, stock rom, i'm with Cypress and AX8MT module and it's working fine, no lags, sensitive, and the dual touch is also very fast responding.

It seems that corner touch screen sensitivity issues are prevalent among all nook color users. What I'm wondering is, does nookie Froyo have this issue as well?
Yes, or at least for me.
No difference on nookie froyo for me either. I'm pretty sure its a hardware defect and not a software one.
I'm on a rooted stock, but my edge sensitivity issues went away when I loaded one of the overclock kernels. I don't know how the two could be linked, but it is the only explanation I have for the difference. I'm not sure if that's been explored on Nookie, but I thought I would share since that would point to a software issue rather than hardware.

That I'm not so sure of. Using "Touch Test" I see all touches, but they seem to get shifted slightly when I press near the edges. Maybe this could get solved in the driver (maybe with some help of calibration tool). I hope to have time to play with this sometime soon.

How can you be so sure?
If i use google market, sometimes the search button is hard to press,
but using appbrain market it works 100% of the time without problems.
No its not H/W I think, run some tests and corners work fine.
Its certainly something else, I also have better response after loading OC.
I've seen the same thing (I would bet every nook owner has.) The Market Search especially takes *%)(!%&! forever to get to work for me.
I've seen the same behaviour as well, some apps the corners take 18,013,108 tries to get to work, other apps I'm all "Whoa, first try and it worked?!".
I put the 950 OC on my autonoot but then I started playing with Froyo on a C10 SD card (very quick) so I don't know if the OC's actually helped with the corners or not. And of course this is the one day I leave it at home since I got it.

Use Menu>Search instead of trying to touch the top magnifying glass.
Happens to me with Froyo. I seriously doubt its hardware related. Seemed to work fine on the stock B&N.
It is common for digitizers to be less accurate along the edges but the Nook Color seems worse than normal. I've noticed the problem regardless of kernel or rom used.
I'm pretty sure it has something to do with the LCD Density. All buttons/elements are a lot easier to press when I switched to 240-250. It does look ugly though, it'd be a lot prettier when we get a custom rom running.
Sigvard is right. Fixed for me by chaging my LCD Density. I set it to 200, which is a little too large for me, so I may lower it. But since doing that I have had no problems at all.
Guide here: http://forum.xda-developers.com/showthread.php?t=889951&highlight=LCD+Density
Ha! I have the exact problem even with stock rom. I though it was the problem of the particular corner of the unit I got! It is much easier to press the button in landscape view.
I dont believe its the screen. Download AppBrain and tap the search button. it works 100% of the time
It is the screen. Use a drawing program and notice how it is easy to draw a straight line in the middle and not as easy on the sides and corners. Note, you need to drag your finger slowly or else you will see more interpolation.
Raising the LCD density just hides the problem by making the hit zone bigger. Fortunately, I can live with the it.
I've flashed twice in different ICS rom from TW and Germany. Faced the same problems on the left bottom screen. Touch is most sensitivity and not accurately. But using S pen is fine.

IMO sensitivity in ICS Roms has improved, but you say it's TOO sensitive?
I haven't experienced such a problem. Try calibrating your screen, maybe that will fix the problem!
Hope that helps!

Hi,
I've started to notice that my spen doesn't seem to be working anymore. I never want first day that it is very difficult to use the pen for taking notes, drawing, etc. Wasn't dropped or anything like that, it just seems to of degraded over time.
I've tried it on stock market rom and cm9 and having the same problem. When I checked the pen on stock rom, by showing pen location on screen, it shows it (both when touching and above the screen), so it is being sensed.
Finger touch works fine so I think the digitizer works well. I also have a screen protector on, but I've tried taking it off and having the same issue.
Does anyone have the same problem?
Also, is there a way of increasing the sensitivity to the pen to see if that improves the problem.
Cheers,

I guess it must be due to minir wear-n-tear . You may try to OPEN and RESET at respective parts of your SPen.
I had posted a thread titled "Anatomy of SPen" on this forum, which might help you understand how to open and reset it.
Hi,
There's this thing about the dual-touch module that really bothers me a lot lately. Since it is difficult to put the issue into words, I've uploaded a video for you people to see what the thing is.
See how the touch is recognized in the middle? It happens quite often since I write text messages very fast. Is this possible to fix? Or do the hardware limitations force me to live with it?
Sorry about the quality - the video was recorded using another Xperia device
Relevant info:
Digitizer: Cypress
ROM: FroyoPro v2.5
Kernel: Stock
Have you seen this video? It is too smooth for syncaprtics. It is definitely cypress.

Sorry I haven't mentioned this before. The touchpanel is definitely a Cypress one. I will add this information to the first post.
Also to note: ROM is FroyoPro v2.5, kernel is stock (bootloader cannot be unlocked).
Is this even normal behavior for the Cypress digitizer? It almost seems as if you suggest it isn't. This bug/problem is one of the things that actually made me want to root the original device. But even though the phone is 2x better than it was before, this problem still persists, and can be annoying at times.
The solution would be most welcome.
This is quite annoying when I'm typing on the keyboard... when I type quickly it thinks very often that I pressed a button halfway between my 2 fingers...
edit: I have tested it with 3 multitouch tester apps and I can't reproduce the problem. Something else causes the keyboard to operate wrongly (happens with all keyboard applications).

Same thing happened on stock ROM (I applied the dual touch module before switching to FroyoPro), so I don't think the ROM is responsible. All the keyboards suffer the same issue, except 2.3 Gingerbread Keyboard which performs passable. I really wonder if this case is specific to my phone or do other people have the same issue. Because, if they do, I might as well drop this and blame it on the phone

Here's just an update on the issue.
Recently I had a chance to try another Xperia X8 with a Synaptics digitizer, and luckily the owner had a Gingerbread ROM installed on it. I can say with certainty that dual touch had indeed performed better in typing than on my unit, albeit the Multitouch Visualizer gave some really strange results when both fingers were on the screen. The owner also said that other effects like pinch-to-zoom and performance in games seem to work a lot better on Cypress.
I did some homework regarding the dual touch module made for Cypress devices. Among other things, the developer wrote about this issue which caught my eye:
"- on FroyoBread sliding position of touch from first finger to second if you release first and quicly press second finger in another position - could you check both v003 versions guys ?"
FroyoPro actually is a continuation of FroyoBread, and this sounds very much like the issue I'm having right now.
Can Cypress users (especially if you're also FroyoBread users) please confirm if this problem is common to all of us, so perhaps flashing another ROM, like Gingerbread, could actually solve it?

did i understood your statement right?.. that if you press a finger at one position and then press at another postition and quickly remove the first finger it acts like a sliding gesture...if so then yes it does... it does the same on all the roms i have tried yet...

Aye. But that was the statement of the module creator, AnDyX, not mine Just tried it on the launcher screen. It was funny that it actually forced me to the next screen without doing the slide gesture. This confirms the issue. The module perceives it as a single touch that slided from the first to the second finger. Not as two touches altogether. Typing with it is really a nuisance.

that action is so fast that it interprets it as a continuous slide....we cant do anything in that.. but it should not give problems in typing... just try to estimate the minimum gap that is required for proper typing so that you can type at the max possible speed.....

Yes, I do it with relative success. But then again, I'd rather go without it
Thanks for replying. The issue, it seems, cannot be fixed.
1.Turn on your display and wake app like the paintsoft.
2.Put your Z1 onto a insulated one, like rubber sheet and your Z1 has to be naked.(without any cases)
3.Wait 30sec or more.
4.Draw a line, and during drawing, touch the side panel. Left side and right side should be touched by two fingers. and cover of microUSB port and sim port should not be touched.
5.About 70-80%, You can reproduce the problem.
The movie is here
http://youtu.be/CeAw17LrdKE
This problem may be caused by bad insulating.
But I don't know this problem is occurred in all Z1s.
This problem of touch panel can be occurred variable timings.
People who playing games or using pattern lock will recognize this problem easily. but difficult for who Not playing games or Not using pattern lock.
This method can detect the potential error of your Z1 it looks no problem.
Please test your Z1. and if the problem is reproduced, you should go to store and make a claim!
and replaced one if you get, please re-test and report here.

For few weeks I never saw that problem on mine so I was not worry about it but today I tested few nice games and I realized that after a minute playing the game (Minimotor or HAWX) the virtual joystick stopping working. I have to retouch the joystick with my hand or take off my hand from the phone. All the time.

How it's possible the problem of the touch screen is because is too sensitive? I hope there is a solution via software but for there is some lack of insulated between the touch screen and the rest of the phone. That why when you touch the frame the touch respond very badly.

so to make less sharp ,It will be ok. perhaps.
