Hi guys,
I have noticed that randomly, there is a touch sensitivity issue that happens to the Ultra. Sometimes i find my self tapping really harder than usually required for my touch input to be recognized. A simple tap that usually works gets ignored. This issue seems to go away if i restart the phone.
Now the weird thing is that this is my 3rd Xperia Ultra. The ones i had before had this issue as well.
I am not sure if its a software issue or hardware. its really weird though.
My problem with my xzu is phantom tap, because my hand is sweaty, so there is often tap even without touching it because the xzu screen is very sensitive, my solution is using the m glass screen protector.after using it it is less happen.because the screen is now thicker
I have noticed the touchscreen is a little hinky. Missed taps. Taps when I meant to swipe. I can live with it though in light of all the advantages of this phone.

Am I the only one having really poor touch recognition on my A43? Whether I use a finger or stylus, it often happens--about once in five keystrokes or more--that after releasing the touch on an on-screen keyboard, a different key additionally gets registered, sometimes not even a neighboring key. It is very hard to type in a password.
My touchscreen also has this problem. I'll hit one key and it will add another key somewhere entirely else on the screen. Menus will spaz out when I try and scroll through them.
Oh yeah, remember that problem I was having where strange spots showed up on the screen and I had to get it RMA'd? That came back on my BRAND NEW unit. I'm getting sick of the crappy screen on this otherwise great unit =[ Maybe Archos will just give me a refund and I can spend my funds on an unlocked/off contract phone with similar specs.
Sadly, I think this is a hardware issue. I'm not sure there's anything firmware can do besides ignore half of the inputs. But then, you have a non-responsive issue ...
Have you guys tried to calibrate the screen through SDE?
I have a similar issue with my A101, although it's not as bad as you guys describe - sometimes the screen just won't register my touch at all, mostly in the edges of the screen - sometimes I think it's the calluses on my fingers from playing guitar, sometimes I think it's the horrible screen they gave us....

So does anyone not have this problem with an A43?

You might be having better luck because the A101 has a capacitive screen with multi-touch capabilities. They're known to be more reliable than the resistive screens the 43IT's have.

I have a 43IT, which is why I posted Sorry I wasn't clear. I feel your pain. Also, I suggest using your nail or a stylus, as the pinpoint hardness of either are better than the soft, blob your fingertip makes on the screen sensor array.

I generally use a stylus. The problem is probably due to the way the plastic digitizer flexes which generates ghost movement data on release. A glass digitizer would be much better.
By the way, it is possible to ameliorate the problem slightly in software. I did that in the myKbd app for PalmOS. Basically, you filter out some very rapid motions. It doesn't affect sensitivity in any significant way.
The reason I'd like to know if everyone has this problem is because I'm going to send my A43 in for warranty repairs, and I am wondering if I should include this problem (in addition to the annoying bright 1/4" area on the screen, and the occasional timeouts when writing to internal flash that result in the device hanging).
Have any of you experienced something like the screen registering a touch even if you didn't really touch it (or it didn't feel like it did) while having the finger very close to the screen?
Its something that happened me very randomly and not so frequently with my iPod Touch, but now with the S3 is something definetively more frequent, and sometimes is annoying, very weird!

Is there any particular reason on why it happens, or anything that could be done to 'fix it'
Its just a little nuissance,for example after typing a letter in the keyboard, in just one press it will register 2 or even 3 touches, one before really touching, when touching, and one after touching (being 3 times very rare and 2 touches a bit less than uncommon)
Weird, though the s3 screen is super sensitive I haven't experienced any double touch so far. Try testing your screen using multi touch tester and see if you can trace anything weird there

Just wondering......can it be affected by static electricity?

I've had this a few times, but not so much that it's annoying. I'm using a generic e-bay screen protector. Anybody else who is having this phenomenon got a screen protector on, or are you going nekkid ?
I've had it too but very rarely. Don't think it's much of a problem. Capacitive touchscreens work based on the electrical charge our skin possesses so your static charge theory might be right(correct me if I'm wrong)

I'm guessing wearing wool or nylon clothing here might be part of the problem! Also atmospherics can play a big part. I seriously don't think this is a hardware problem at all imho.
Yep i get this too, can espically see it on the 'test' screen where you are drawing on it, sometimes my finger passes right over it and it registers it. I'm going with static electricit and the screen protector generating a little current just before your finger touches as the culprit.
So, every now and again, usually while I'm scrolling through a page (up and/or down), it's like the screen registers a touch or even a movement in a different location of the screen, often leading to the statusbar pulling down (even though I wasn't touching anywhere near the statusbar), or, if I'm scrolling through the app drawer, the phone will launch an app that I never even placed my finger over while scrolling.
It's kind of driving me bonkers, and I'm wondering if this is something software related that is affecting multiple users, or if I have some sort of wonky hardware issue with my own device that isn't affecting other people.
Any input is appreciated. Thanks!
Just an update on the situation. I had the phone replaced and still noticed finicky touch screen response.
Determined that there was a common denominator between both phones, that being the BodyGuardz screen protector.
After removing that screen protector, touch response is now crisp, precise, and consistent.
I've bought a used S9+ like 3 days ago and run a QA test inside the phone. The screen was fine and it responds normally, however after 2 days I couldn't use a keyboard because of its issues while typing. Basically, when I'm typing a longer sentence, I have to either slow down or sometimes press a button 3-5 times for it to respond. It stared to occur yesterday and I don't know if that's the touch control issue or something with the display. P.S. I've tested it on Gboard, Samsung keyboard and Grammarly keyboard, all with the same issue.
Is there any fix I can do without paying for a new display? It will cost me the same amount of money as the phone itself.
Thanks!
Are you using a screen protector? If not, try it. Maybe touch sensitivity is turned on in display settings, try changing it to see if it's better. I've noticed that on some screen protectors, they retain a lot of humidity so I have to constantly clean the screen to get rid of "ghost touches"

No, I don't use any screen protectors. My phone has a Spigen case, which is slightly over the screen both at top and the bottom. I tried to turn on and off touch sensitivity and it didn't help. Funny part is that it sometimes stops and goes again.
Had this myself, especially with the space bar ?
Same here, have to press space up to three times (intermittent issue). Screen protector on, sensitivity does nothing.
Problems with the touch screen. Apparently 1+ did it as a protection for accidental touches. Along the entire perimeter 2-3 mm from the edge, the screen responds to pressing with a delay of 1-2 seconds! Check and comment please.
OxygenOS v.11.2.3.3
I checked it again, the problem is as in the video above, the delay around the perimeter. But at the same time, there are no delays in the keyboard when typing. Apparently this is a software limitation of some kind from phantom touches, and if an application is open, for example a keyboard, then the touch reacts 100%
Plus I still have my phone in a case,
so I had to get it out of the case to repeat the test as in the video above. There are almost no delays in the case.
Anyone else? Please comment ...
I think I remember having something similar on the 7 Pro. Don't think there was ever a fix for it or anything.

Any OTA updates/fix since?
