IOS 9.2.1 broke the accuracy of the touch screen

After my upgrade to 9.2.1 the precision of touch screen makes the phone almost useless.  I can not type accurately and cannot even open the applications I want without having to open other applications.

When I lock the screen and then unlock it seems to fix the precision of touch screen for about 10 seconds, then it will return the incorrect touch screen.

Another question, I noticed is 2 white vertical lines that appear in the home screen randomly, but when I lock screen is not there... so I'm glad this isn't HW issue.

This started last night after being upgraded to IOS 9.2.1

someone at - it solutions on it?

Reset. Restoration. Restore as new.

Those who characterize the troubleshooting steps. I have no problem with the precision of touch screen, nor anyone I know.

Your description of the "white lines", would seem to indicate corruption of iOS, in which case a restore should fix the problem, or a display failed.

    My iPhone 5, iOS 9.0.2 does not respond to touch. (broken touchscreen) and my home button is broken. my battery is fully charged so that it would take too long to wait until it turns off. I need a way to Hard reset it without a button at home and the touch screen.

  • Are the touch screen and the LCD on the Acer Aspire V5 - separate 122P?

    Dear members,

    I broke the touchscreen for my Acer V5 - 122P when the laptop has fallen. I'm trying to find out how I can have it replaced. How much should I order? The LCD works but the touch screen is not.

  • How to make it turn off the touch screen?

    I don't want to use the touch screen. How to turn off the it? It is activated by all sorts of things, like my touch cat's tail, or an insect landing on it, or a curtain blowing against it. I don't type using the screen, I prefer the keyboard that I can not type quickly on the screen. I would like to turn off the touch screen when I use it not (most of the time), or even permanently - it is not useful for what I want to do that the screen is not as sensitive or as fast as the input devices that I usually use.

    Thanks for any help

    Hello

    Have you found a way to do it?
    I think that it of not possible to disable the touch screen.
    Found no information in the user manual. Maybe you can check the BIOS settings available. Switch on and press F2 to enter the BIOS.
    But to be honest, I doubt that a power option would be available there.

  • How to disable the touch screen of the Toshiba LX830 - 11 d

    Hello

    I managed to break the touch screen on a Toshiba LX830 - 11 d.

    The machine runs Win8 and always works with a USB keyboard and a mouse, although he thinks there are plenty of touch of the finger around the damaged area.

    Is it possible to disable the touch screen feature so that I can use it as a 'normal' PC or remove the screen touch himself leaving a simple LCD screen?

    Thanks for any advice.

  • AT300 - area on the touch screen, pick up ghost keys

    Hi people,

    I'm having a problem with my Tablet AT300 where it that takes the touchscreen touches - many of them - in a place where it is not to be touched. When I turn it on, it starts to go crazy with the vibrations repeated thought to touch screen that is to be touched. I see the behavior that it is picking up in an area of the screen - the left-hand side from the bottom when held in orientation landscape with the camera at the top. I can say that it's in this area because it retains hit the back button, and if I do then rotate the device to the left, it keeps bring up the pop-up menu settings of the lower right and close it again.

    I saw one report of this type of behavior that was caused by a loose wire to drop the device. My Tablet has fallen a few times, but not on hard surfaces. It is possible, but it could also be something else. I am reluctant to remove if it's a software problem (well the fact that it is an area of the touch screen suggests it's material, I guess). I guess I could reset it hard, but to be honest, I don't want to do this because my daughter won't lose its apps and saved games.

    So, who is the most likely scenario here, and what is the best way of difficulty? Any help would be greatly appreciated.

  • HP ENVY 15-ae178ca laptop: I disabled the touch screen on my laptop HP ENVY how I get it back?

    I have disabled my touch screen, how do I get it back on?

    @scoop58

    Welcome to the Forums of HP,
    I hope you're well

    I understand that the touch screen no longer works after upgrade to windows 10,
    don't worry, however, as I have a few steps that should solve your problem:

    To activate the touch screen driver in Device Manager:

    1. In Windows, locate and open the Device Manager.
    2. Expand the Human Interface Devices section.
    3. The touchscreen device is labeled HID-compliant screen touch, or similar. Right click on the touch screen device.
    4. If the option to activate the device is included in the menu, click Activate.

    Keep me posted,

    Kind regards

  • HP Envy disable the touch screen

    I need help, disabling the touch screen on my HP Envy. I tried to get him here, but I found nothing. I'm not really sure how much more explicit I can get about what type it is. If you have any advice on how to understand this, that might be useful. Thank you.

    For Windows 8 and 8.1 with a newer laptop, open Device Manager. The same procedure is likely to be quite similar for Windows 7.

    Right click on the tactile HID-Compliant device and select properties to call the Properties window.
