Does your phone has a protective case, film or glass? if it does, remove them and see if you experience the same issue.

I have this problem, especially on home page. It's like I'm holding my finger on the touch screen and want to touch another area. The only way to get rid of it is to press the power key and turn the screen on and off.
Any solution ?

No, it doesn't work at all.
I tried everything but nothing could change it. It happens randomly, especially when touching home page for a couple of seconds or touching the screen repeatedly or with multitouch. Sometimes the screen freezes and the only way is to turn it off and on again. Not sure if it's a hardware or software issue.

Xperia XA multitouch only accept 4 fingers and ghost touching

My Xperia XA has a problem with multitouch. I tested my device with some apps from Play Store like MultiTouch Tester and it only accepts 4 fingers, I think it's supposed to be 10 fingers multitouch but it's not. It also is acting erratically with the touchscreen especially when using multitouch on home screen. Then it freezes the screen or sometimes just the notification bar works and no response to touching on other areas.
I don't use any cover and screen protector and also did software repair with Xperia Companion and it didn't help. My device is updated with 33.2.B.3.81 and no other update is available for me. The model is F3116
Any solution?

Just after facing with that touching problem I used Multitouch Tester to see what's wrong with it and one thing that I noticed was when I touched the screen it showed me 2 that means somewhere else has already been touched and that is the problem but it doesn't show where.

Could you please please try to boot on #safemode? To see if the problem occurs? Also try to perform xperia diagnostics on settings-about phone.

If you recently installed a screen protector, it might cause similar problem

I don't have any screen protector or cover, I did factory reset and also repair with Xperia Companion. xperia diagnostics shows nothing and touch screen works %99 of time but randomly it happens. Also did safe mode and it happened again.
Could you tell me if yours just accept 4 fingers or 10? I used two apps ( YAMTT, MultiTouch Tester)
I appreciate it my friend.

In the descriptions of XA it is said: up to 4 fingers.

Ok so at least I know that 4 fingers multitouch is not a problem. Hope to get rid of that ghost touching as well.

MarlonUk1 — Tue, 08 Nov 2016 10:01:40 GMT

oh yeah, it only supports 4 fingers only, but if with 1 finger registering 2 , can you test if it still detects 4 fingers?

Got the same problem, i've already send my phone to sony but they did'nt found any problem

The ghost touch is always in the same area : top right of the screen, just in the corner

Turn on Force GPU rendering on Developer options and that might help.
