SP touchscreen problem

[romario7]

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 the hard reset.

No, I don't have screen protector

Try a software repair:

Try to update the firmware and phone.

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

How can I start phone in safe mode?

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.
