Xperia L touch screen phantom presses

[gardener4u]

My Xperia L has started to behave like some one is randomly pressing and swiping the screen.

This usually occurs after side button is pressed to switch screen on. It can be just a few presses or can go on for many minutes. It happens during charging or when powered by battery.

It also occurs sometimes during use. It will cut off off or make a call,  send texts, change settings, plays music, changes time and date and generally is a real pain! - It's almost as if it has recorded a load of previous presses and is playing them back yet really pressing the screen does respond instantly but with phantom presses continuing (usually very rapidly) afterwards.

It has once successfully entered my swipe Patten and has placed an emergency call - so am now quite desperate to get a fix for this.

I have latest updates installed and removing the battery fixes only for a short time.

No. what is it?

Now when I try to use SUS it does nothing when plugging in USB cable. Before it connected and  tried to install driver QHSUSB_DLOAD

Oh... If PCC is Sony PC Companion - I do have that and it connects ok.

here you are

PCC

download and install it...it will install all needed drivers

its some kind of device manger

after installing PCC connect your phone to pc and PCC will find it and install needed driver..after that try repair by SUS

[gardener4u]

Well.. PCC was installed and all except File Transfer works (that button does nothing at all - never has). Did backup earlier because SUS stated it would wipe data (and it did) before complaining about missing driver and stopping.

Uloaded PCC and reloaded it. SUS still failed with same error. PCC has it's own fix option available after you check software. Seems similar to SUS and also failed due to 'missing driver' but gave no more details.

I give up and will phone Virgin for replacement handset. I am hoping the data backup works on replacement because Restore took 45 minute to tell me that restore function had failed and to try again from step 1. 45 minutes later and same message!

So sorry to hear that

wait..did you charge your phone to 100%??

Yes battery was 98% when started. Luckily Google+ Sync has started putting my apps and data back - I had forgotten that I had set that up when I first got the handset. Address book is still vacant but I'm sure that will arrive back soon also. It is still downloading and updating.

No phanton screen presses for a while either! - Another site suggested I activated usb debugging. Not sure if that has helped or not but PCC File Transfer now works and that never has before!

Thanks so much for all your help and suggestions. Original problem maybe solved?  I'll confirm tomorrow.

you are welcom and good to hear that

keep me update

[gardener4u · Accepted solution]

Well the phantom key presses have stopped with none during last 24 hours. This was after USB debugging was activated and PCC update phone software / repair phone was run succesfully (2nd attempt)..

All account data has returned including address book, apps and photo's. 'My Xperia' is unable to find my phone now but I'm not too worried about that.

I'll mark this as problem solved. Thanks

I also have problem with my xperia zr phone. I am not able to create a new post. Can someone help?

"xperia zr behaving randomly wierd.. opening random apps doing anything without even touching the phone..randomly click even though i did not touch the display and it happened very often. It made the homescreen moved and sometimes executed many unwanted task by it self. Phone is not in my control and not taking any of my input even in safe mode. Even if I take out SIM it is behaving same way. Can anyone help me?"
