Xperia L touch screen phantom presses

gardener4u — Sat, 08 Mar 2014 08:29:42 GMT

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.

I get this and as you said removing the battery or force shut down will resolve it - I've removed the 3rd party screen protector and removed it from the case and it still happens so it's not those things

Thank you Danial-mach1, I wasn't aware of this safe mode. I am trying it now.

Because fault is intermittant (worse longer phone is not used) I will write later to let you know if this has worked.

I had already deleted all recently added apps but new os may affect earlier ones.

Ok..keep us update

Re: Xperia L touch screen phantom presses

gardener4u — Sat, 08 Mar 2014 09:41:19 GMT

That was quick! - No it is already tapping away to itself. So not an installed app causing problem.

oops!

are you willing to software repair via SUS?

but keep in mind all of your data on internall storage will gone..so backup if you want

Re: Xperia L touch screen phantom presses

gardener4u — Sat, 08 Mar 2014 12:19:52 GMT

Backup took forever but finally finished. Will give SUS a try now. Thanks again for your help. Will report back when complete and restored.

Unfortuneately SUS won't run. It downloaded ok but, after pressing volume control whilst plugging in usb, it reports that it was unable to install driver QHSUSB_DLOAD because driver is not found. 'More details' suggested I have either no internet connection or automatic updates were swithched off (win 7) but connection is good and auto updates are on.

I don't have QHSUSB_DLOAD on my pc nor can find a safe looking version on the net. It apears to be just a usb driver and the one that comes with PC Companion is working ok but obviously there is some difference.

You are welcome friend

Do you have PCC on your pc?

Re: Xperia L touch screen phantom presses

gardener4u — Sat, 08 Mar 2014 14:15:16 GMT

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

Re: Xperia L touch screen phantom presses

gardener4u — Sat, 08 Mar 2014 14:18:08 GMT

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

Re: Xperia L touch screen phantom presses

Danial-mach1 — Sat, 08 Mar 2014 14:19:39 GMT

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

Re: Xperia L touch screen phantom presses

gardener4u — Sat, 08 Mar 2014 16:16:22 GMT

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!

Danial-mach1 — Sat, 08 Mar 2014 16:20:35 GMT

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.

Danial-mach1 — Sat, 08 Mar 2014 17:42:59 GMT

you are welcom and good to hear that

keep me update

Re: Xperia L touch screen phantom presses

gardener4u — Sun, 09 Mar 2014 22:30:13 GMT

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
