[Q] Screen not being sensitive on some parts in ALL CM7 roms?

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!

hmm... instresting... i don't' have this problem on cm6 and stock...other's have this problem on cm6 and 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.

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.

White Spot where i touch !!!

Hi,
Whats that white spot and how is this appeared.
it follows the path i touch on screen ! Slides, slight touches, everywhere !
at first i thought this was an hardware issue with the screen but when i tried to take an screenshot it was still there so its a software thing.
i dont know how it came and i dont remember seeing it last night when i using my phone.
any Ideas ?!
Thank you.

settings--dev options-- show touches

Anyone facing ghost touch on rooted 4.4?

I have unlocked and rooted with the latest 4.4 but have been facing lot of ghost touch, over heating and freeze. Is anyone else facing the same issues with their z1?

I haven't as yet but I did notice that the touch screen issue I had where my finger / thumb would lose contact briefly with the screen.
Hasn't happened a lot and holding the metal frame fixes it.
What youre describing could be a knock on effect of the new firmware having a higher sensitivity to the previous firmwares, I know Sony were aware of the touchscreen issue that people were facing and there was a fix where you could alter the sensitivity of the touch screen.
Could be that your touchscreen is set too high for your device in particular, either that or it's a problem with the touchscreen or even some dirt.
Give it a good old clean and a few reboots.
All the above is speculation of course, just having a stab at it for you m8.
Not sure where that thread is about the touchscreen but it's definitely in the Z1 forum.

So on the base that you were on you didn't have any issues, Rooting itself will not cause this issue.
What base were you on prior to rooting and what are you on now?

Same here, after rooting mine, it starts again the touch screen to respond strange, but not a big problem. Did not had this on .136.

Actually Rooting can cause the issue because the Pre-Rooted version can be different from the original one installed on our phone.
After I received the phone from Repair they updated the Software and then I updated to .136 officially and the issue disappear, never had even a bit of it. Then I rooted, but to do so I used a different Base, NUT use the Frence region I think, and after that on mine .136 the problem with Touch Screen appear again, not badly, all is fine but sometime it skips something.
So I think it's really related to the Software and the all the phone have a specific Base.

Then it would be down to the rom and not the rooting process, rooting alone won't affect the touchscreen m8.
The Rom could though.

Of Course.

i have not experienced ghost touch but i did experience the screen failing to register two finger touch sometimes.
what i mean by that is when u quickly touch another part of the screen after its been touched it would register it as a swipe.
very annoying when typing keyboard or even pressing key pin on lockscreen.
i reproduced this in touch test and
once it registers as a faulty swipe while holding down the touch
it keeps registering swipe wherever the other finger presses untill i stop touching.
also when i installed a fresh rom it seems that the touch is very sensitive.
i tried this out http://forum.xda-developers.com/showthread.php?t=2691849
its not a fix but it helps out.

I think i have drilled down to the cause for this issue.
1. I started mounting my phone on my motorbike and ride. Due to excessive vibration the screen might have started acting out.
2. I also read that x alert causes this.
I have locked bootloder and installed stock ROM. Lets see whats happens

What is that or where it is?

Been trying to find that adjustment you can make for the touchscreen but can't find it. Its an adjustment of a file within android which deals with how sensitive the touch screen is. Buggered if I can find it though. I commented on it too. Eluded me.

Maybe that Calibration.ini file magically can help?
BTW, if you find that thread let me know because I am interested too in changing the sensitivity, I will like to play with that.

I would definitely be interested in this as well so could you please inform me as soon as you find something? Thanks

I am unable to pin point the problem.
1. Its not bcoz of root/boot loader
2. Not bcoz of mouting it on my bike. Infact when i mount it, it functions normally.
3. Ghost touch worsens when i play clash of clans but it is there other times too.
So its either bcoz of over heating (games make the phone heat a lot) or water entered it or i am not sure.

He found my thread
I always surf the forums and check out what is happening, and this thread did catch my eye
I don't like to think that the touch screen issue is hardware related. I really hope it isn't.
Don't put your heart on this 'fix', as I have lost faith in it myself...
I'm going to post there now as well, to tell people what I have said here.

Touchscreen or Software Issue?

Hi guys! I just upgrade from a Nexus 5 to S6 Edge. I am having an issue with this new phone not sure if it is affecting everyone or just me... :/
I am having an issue to swipe on some applications. One of the application is Swiftkey. I find it very hard to swipe to delete whole word. (You need to have Swiftly Flow disabled.) My music player (ZPlayer) i also hard it hard to swipe to skip songs as well. Is it just me or everyone is having this issue? I have used those touchscreen tester application and find my touchscreen to be fine.

Hey man, I'm having the same problem, definitely a software issue as I tested the screen via *#0*# and it's working.
Any updates on your end?

No solution so far but just living with it... I am surprised that this matter is not noticed by many users yet. :/

Had a problem with swipes being interrupted and taps registering multiple times. Got the screen replaced through warranty and the problem is gone. The problem seemed to be caused by pressure making the digitizer make contact with some other part causing erratic touch response.

Weird touch screen problem

As you can see in the attached files there's a 2 vertical lines. But I only use 1 finger to draw that. That's the reason why I can't create a message using swipe because as the finger tip passed on that region the swipe is cut off. Anyone experiencing this? I'm on last version of MM.
