touch screen is registering wrong touch UI events and miss taps

Dear Sony,  I am pretty sure you sold me device with buggy touchscreen (and with other bugs about wheech you keep being silent as fishes).  I already received my f3212 from your Local "Service" center and had been doing all Captain Obvious "solutions"  coming from your outsorced  "experts". And your Local "Service"  Center is refusing to confirm obvious bugs.  So I have to waste my time on searching ways how to prove numerous Sony bugs. 

  • UNFIXED TOUCHSCREEN BUG is looks like that -  here is the touch event trace (i quickly tapped the screen -  and there should be a dot - but your buggy system UI is registred a SWIPE).  And its from under the safe mode. 
  • IF SONY IS TRYING TO ROB ME BY SELLING UNTESTED RAW DEVICE WITH NUMEROUS OBVIOUS BUGS? AND DO IT REALLY REFUSING TO IMPLEMENT ITS WARRANTY AGAINST CONSUMERS WARRANTY CLAIMS?

Re: touch screen is registering wrong touch UI events and miss taps

Dear friend the thing that I want to tell you might be irrelevant but I had a touch problem like ghost touching and tested that with some apps that were showing me there is another tap on the screen so it was awful because it was like there are two fingers on the screen.
Then I turned on "Force GPU rendering" on Developer options and after that no problem with that.
You tested everything so it's not a problem to test this thing out.
Hope it works for you Slightly smiling Face

Re: Xperia XA Ghost Touch

thanks for trying to help. But it is pointless, as buggy the whole touch screen procesing system software. I still missing part of taps and have very bad stylus responce (sensitivity) (and my stylus is Wacom who knows everything on good styluses). As well there is the bug with text selection cariages - they become unmovable when you sellect text located near the screen edges. They just stuck as they cant be moved there because of their own huge width...
And it not solve my microphone bugs and numerous other Sony software bugs. And all should work wo any dev options.

Re: Xperia XA Ghost Touch

Don't really know how to link posts or anything, but my XA Ultra stopped responding to touch and started tapping the screen in multiple areas at once *by itself*. Another thread saw an association with using a memory card, and mine did push a notification about being corrupted right before it force-restarted and began this behavior. The memory card was formattable and must have been corrupted somehow by the phone, rather than by internal failure (had this happen before with this and other phones). Just wanted to throw this out there because it seems relevant, but different in the sense that mine is completely unusable at the moment.

 

Anyone have any ideas?

 

Also, if I send my phone in for repair and Sony finds, say, the screen to be defective, does Sony replace the screen, or do they replace the device with a refurbished unit? I've taken really good care of my phone and hope they won't give me someone else's "fixed" phone they returned for service...

Re: Xperia XA Ghost Touch

XA Dual. Has ghost touch which touches (weirdly) only on the second row from top, second icon from the left.
If I have an icon there it will activate the app randomly without my touch. If I have that location blank (no app) the screen will turn off. This is preferable because then I just press the button and the screen comes back on without the ghost operating.
The ghost will operate sometimes when typing, for example when typing this, because the cursor was "in the zone" it started to misbehave. Also the cursor location is unreliable, occasionally flicks to another location in the text above. Happened several times while typing this. Practically unusable.
Very annoying - makes me think the screen is defective.
I have had 4 Sony phones previously, all have been good.
Soon I'll stop perservering with this one and switch brands. Once burnt I won't come back!
