SP touchscreen problem

romario7 — Sun, 25 May 2014 20:45:42 GMT

Hi, my XSP has a big problem. Sometimes when I unlock my device, something starts to touch my screen. It happens usually while texting. I can't write because the phone do the "ghost touches". Glove mode is OFF. Other thing is that multitouch is not working all the time. It starts working only when I restart my device. Restart with "ghost touches" didn't help. Please help! Sorry for my bad English

Do you have a screen protector?

Try to update the firmware and phone.

And start the phone in save model to check if it caused by 3rd app.

If that happens only when you are charging it or when it's plugged into a laptop pc, low charger output or non-grounded usb output might cause the problem. Software repair does not fix these. You should use the original charger and try not to use it while plugged in to a pc.

Sometimes when your thumb is too close to the screen it can be registered as a touch input, even your palm can trigger these. And yes this happens even when glove mode is off. But it is not as intolerable as you've mentioned. I suggest you turn on the glove mode and just reboot your phone.

Also safe mode:http://talk.sonymobile.com/t5/FAQ/How-to-boot-your-phone-into-safe-mode/m-p/348008#U348008

Thank you!
But I use original charger and don't use pc as charger. However this problem with touchscreen happens a few times a day but when it happens, it is very annoying. This morning I can't turn off my alarm because of this issue. Do you think, will hard reset or repairing help?

As for me, the ghost touch happens when I turn on the glove mode. In a certain condition (probably something is leaking on the memory) when I touch the screen once, the touch respond seemed like twice. etc etc. When it's happening, I turn off the glove mode. Problem solved, for a while.
After some time (due to memory leak again maybe) the screen become unresponsive. Turning on glove mode will fix this.
And those 2 problems looping on me.

So, there are 2 problems. Glove mode on: ghost touch, Glove mode off: unresponsive screen.
And to fix the current problem is by switching the Glove mode on or off.

The thing about glove mode is it is not really activated when it is enabled. You have to unlock your screen with gloves or something. When it is activated you see white circles showing you where you touch on screen. Sometimes it is activated even though you unlock it bare handed. If that happens you can deactivate it simply by locking and unlocking with bare hands again. At least that is how it is for me. I had a lot of touch problems without glove mode, now I never disable it. And touch response is much better. Those crazy ghost touches only happened one time while I was messaging my friends while plugged in to a laptop.

When screen does not respond, holding the phone in hand helps somehow.

For alarm, you can set it to stop when you press the side buttons.

I don't think hard reset or repair would fix it, but you never know and it wouldn't hurt to try. If nothing helps you should send it for repair.
