The display touch of right side on my mobile not working is it hardware problem how to repair it
In my case it was the left bottom quarter initially but it continues to spread! Land was never my primary device plus its pretty slow so repair costs are hard to justify. Only use it for extra accounts for apps that enforce per device limitations. I just use an USB OTG mouse when some UI element is an area where touch is no longer registered. Although I am thinking about getting a pure(without any dongle) Bluetooth mouse but they are pricey...

When I slide out my wizard's keyboard, the touch screen doesn't react to any touching any longer.
Anyone know how this can be fixed? If I re-close the wizard, the screen is fine again.
Very strange!
Yes xtrange!?
Its soo xtrange
does you upgrade your wizard... or got this issue since you own the device?
maybe a drop!!!!
We need every info you have done since it works to the stops time.
Well, there's one of two explanations that seem most likely to me:
1) Your device, due to some software malfunction, no longer responds correctly to touch input while in landscape mode. To test this, with the wizard keyboard still away in the locked position, open the screen settings, located in the 'System' tab of the control panel. Select an orientation of 'Landscape (Left-Handed)'. Does the device interpret touches properly now? If not, we've found your problem. You can return to portrait (normal mode) by sliding the keyboard all the way out and then returning it to the locked position.
2) One of the ribbon cables, due to age, damage, shoddy manufacturing, etc., has become loose. This means that the force of your keyboard sliding out may push a few of the internal contacts into a position where they no longer make a good connection. If this is the case, your problem most likely can be resolved by opening the device and securing the touchscreen ribbon cable. There's a service manual floating around that can help you with this, if you're brave enough, but I don't suggest you try it until you've evaluated the possibility of a software problem.
Haha nice. I never paid attention to notice that display screen. You were totally right. Swapping it to landscape via software, it is still working so it must be an internal cable.
Do you know if the same cable operates the 4 way arrow keys on the front face of the device? up/down works, but left/right does not, but this is all the time not just in landscape.

Chances are the flex cable between the mainboard & the screen sub-assembly is faulty & needs to be replaced.
You can find them on eBay or buy a faulty unit off eBay & re-use the flex cable to fix your unit.

Hi,
I've got a problem with my HTC Touch Pro... Last column of keys on HW keyboard (except enter) doesn't work... Do you think it is possible to be caused by some software trouble?? In the other case is it possible to repair it without help of service? I'm using EnergyROM WM 6.5.
thanks for reply
Hi,
most probable it's a hardware problem. Normally, after a couple of years, frequently used keys tend to become unresponsive or at least need a heavy push to work.
You can find a brand new keyboard + tools on ebay.
Sounds like it is a break in one of the lines in the ribbon cable connecting the keyboard to the mainboard. The reason the 'Enter' key still works is because it uses two contacts the other being in the adjacent line. On a Touch Pro it is twice the width of the other keys. Either contact will be decoded by the keyboard controller as 'Enter'.
You might be able to source just the cable on its own, if it has a connector at both ends, otherwise it will be a replacement keyboard.
My nexus 7 has a small crack making the top inch or so of the screen unresponsive. generally this isn't too much of a problem as i can just rotate the screen however some apps/games require touching both sides of the screen at the same time and obviously this is not possible.
I have tried to use a mouse to click on the unresponsive section while using my fingers on the rest of the screen but the device doesn't register both inputs at the same time so although the mouse allows me to reach the unresponsive section i am unable to do press anywhere else at the same time, this makes anything that requires multi-touch impossible.
Is there a way to do this or am i going to have to get a new tablet?
I've had my Nexus 4 for a couple years I believe now, and overall it's been a nice device. I've had occasional issues now and then with software (Camera not available message, random powerdowns) but no hardware issues. A couple weeks ago, part of my display stopped responding. The LCD itself shows everything, there's no bars, no visible cracks in the screen. but the left hand side of the screen, I'd estimate about 1/5 the screen in width, no longer responded to touch. The far far left edge, along the very edge of the display, registered, and on the other side of that 1/5 worked fine. The area that was giving me issues was right about where the 'a' key on the keyboard is in portrait mode -- the only location I could press to get an 'a' registered an 's' as well.
This is all being tested with the developers Show Screen Touches and Show Pointer Information turned on.
Then, the end of this past week, it got worse. The entire left half of the display still shows fine, but almost never responds to touches -- maybe 1 in 100 times it will. Thankfully, I was able to get in one of those times and disable my screen lock. It seems to be able to register as far left as an x value ~418. This means the back button in portrait mode, for example, no longer works. To make me even more confused, it seems to register phantom presses. The device can be lying, powered on on my desk, no touching it, and the display starts showing screen touches -- the most common one I see is right about where the word Google is in portrait on the stock main screen. These will continue indefinitely.
All this to say, I suspect my digitizer has had a mechanical failure. Does that seem a reasonable conclusion to you? I like the four inch form factor of the device, and with most new smartphones getting larger and larger, I'm shying away from changing to another device. I've looked briefly at replacing the digitizer -- it seems you can purchase either the digitizer alone or with the LCD, and that when replacing just the digitizer it's easy to accidentally create problems with the existing LCD. Is that true?
Also, the part about having to use a hair dryer to pull the components apart makes me a little nervous. Screws and cables I can handle, but a hair dryer?

I would say it's most likely a hardware problem with the digitizer. The lcd/digitizer assembly is glued together so it's very difficult to separate the two without damaging the lcd.
Unless you have the tools to separate them properly, it's alot less headache to get the entire assembly already glued together.
It's important for note-taking and drawing on stylus devices like the Galaxy Note 3 to ensure that capacitive touch is disabled when using the active stylus, to prevent a palm resting on the display from disrupting the writing etc. Note that this is distinct from software attempts at palm rejection.
We can see that this is done in Ubuntu tablets in standard tools like this by switching off the capacitive touch when the active stylus is detected near the display of the device.
LineageOS is capable of understanding the difference between active stylus input and capacitive touch input -- it displays a little circle pointer when the stylus is near the display on a devices like the Galaxy Note 3, for example. So, how can LineageOS be made to disable the capacitive touch input either
when the stylus is near to the display or
by some manual switch that disables capacitive touch input while leaving active stylus input enabled?
The goal may be similar to S-Pen Only, but this no longer appears to work on modern versions of Android/LineageOS.
So, how can input be set to active stylus-only, with capacitive touch disabled?
