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.

well it is complicated
1st time i bought the phone i felt something funny about how the touch , keyboard and scrolling feels .. i was on miui 9 .. but i couldnt specify what was the problem specifically
i updated to miui 10 and i felt that touch is not improved but worsened or may be it is the glass screen protector i installed .. i dont know specifically but i felt some keystrokes while fast typing were not registered or registered wrong .. also small buttons touch was 50% success rate .. scrolling also was not consistent across different apps and completely different from other previous phones
i updated to beta 8.11.15 now i feel keyboard is a bit more responsive and all keystrokes are registered but some may be registered wrong
what i wanted to discuss here could this problem be multifactorial :
1. could the display be the problem ?! as some ppl mentioned about the tianma display ?! so is there other displays than the tianma ?!
2. could it be the apps ?! i felt different keyboard response and lag according to app used such as facebook, messenger or chrome .. even chrome heavy webpages cause keyboard lag
3. could it be the tempered screen protector as on note 8 and note 9 ??!! but our mobile screen are not that edged and protector fits perfectly
4. i realized that touch is best when carrying mobile with both hands .. less with one hand .. lesser when put on bed or pillow .. impaired if put directly on the floor ?! it appears there is a thing between electricity and grounding and touch
well i would be happy if you shared your opinions about the touch issue and what causes it ?!
i tried to shut off certain features and gestures and tried 3rd party keyboards but there was always minimal difference between .. and this difference is less than found between using different apps

Well i have poco f1 too with the same display of tianna i never had screen bleeding . Neither have heard about it from my friend who bought poco . Maybe only some people had this issue with the screen . Touch screen problem yes the keyboard just goes wild and i cant type fast .
1. Well stop using kika keyboard the defauly keyboard on poco and switch to google keyboard .
2. Go to settings - Additional settings - Language and input - Pointer speed ( Turn pointer speed to zero helps a lot to control the screen in pubg )
Next update fixes the screen issuesso cheers. Or you can install the latest Lineage OS which has thr fix . I prefer MIUI .

In my opinion, those issues are hardware problem, i'm facing to edge screen touch latency, it's very ennoying
I am on Lineage 16 latest build, and the screen is worse than xiaomi.eu 8.10.XX that i had.
The latency is improved but now the screen does not register most of my clicks, i have to press 2-3 times for a button to be acrually pressed which is way more annoying than the increased latency i used to have. This is incredibly frustrating and sad because my beloved poco is getting unusable.
well as i told you i am on 8.11.15 sometimes i feel the keyboard is working excellent but sometimes not .. as in my particular condition 99.9% of my clicks register but as i change apps i feel the latency changes sometime the keyboard is good some time it is very laggy .. also i feel something weird across edges but cannot specify what is abnormal since i use a tempered glass protector and it appears to eat a mm of the edge .. when i press at the lower part of space bar i can see the a space is written and keypress sound is made but the button doesnt appear to be pressed it stays white not grey .. i dont know whether this adds to the keyboard problems or it is just a bug
i think this can be partly fixed over 90% by software but not 100 % .. fast typers will face problems definitely on this phone .. so stay away
So I'm watching youtube on the dual screen using landscape and I want to sleep the main screen so i touch sleep main screen option on the dual screen tab tool, it shows a prompt saying main screen will dim to save battery and swipe to dismiss. I dont touch or swipe anything and the prompt swipes itself away and screen undims or sometimes doesn't even dim. This is also the case with Call of duty mobile, when I'm playing the game in battle royal mode the mini map enlarges randomly even if I don't touch it, and the voice chat options will engage and open without me touching those as well. Anyone else has this problem? Any solutions?
I could have sworn I saw a post earlier about ghost touches, though I can't seem to find the thread it was in at the moment.
I've been using the phone heavily since I got it on April 1st, and I have not experienced this issue at all.
Any chance you had an LG phone prior to this and used LG Switch to transfer over all of your stuff?
I've read reports here that doing so can cause some pretty serious battery drain and/or lag issues, so there could be other bugs as another side-effect.
Have you tried a factory reset?

Yeah I think I read that thread. I haven't tried a reset since I already used so much data to download apps and don't want to setup the phone again. I did use the google cloud restore for my contacts and I also had the t mobile April security update. Mejilan can you tell me if you can put your main screen to sleep while watching a youtube video on the dual screen? Please tell me what kind of result you get. Thanks

I set aside the the dual-screen accessory because it's just too uncomfortable to hold for most use-cases.
I'll go dig it up, plug it in, and give it a shot later, when I have some free time, and report back.

If you play a YT video on the second screen and lock/sleep your phone, the second screen goes to sleep as well.
I didn't bother with headphones for this test, and noticed that the audio comes out of the phone's speakers.
It appears that the second screen doesn't have speakers of its own.
So yeah, you cannot watch something on the second screen while having the phone asleep.
And it make sense. It's just a screen. No second pair of speakers. No second headphone jack. No separate battery. No second set of modems, etc.

It actually was working for me last night as far as the putting main screen to sleep function but call of duty still acts up I'm hoping the update for the game on May 1St will fix, but sure whenever you get a chance...

Actually you CAN watch youtube on the second screen and sleep/dim the main screen by using the floating dual screen button. It has an option asking if you want to sleep dim the main screen to conserve battery life. It does work for me now, I'm not sure why it was going wonky on me when I first posted but hopefully that it doesn't do it anymore. I'm guessing the tmobile April security update did the trick. It's just I have phantom touches on call of duty still.

This is happening to me as well when I'm playing PubG Mobile. The ghost touches are happening not on the map but to the left of that. On another LG V60, the device would get random dead zones as well.
I'm going to do the following test and suggest you do the same and report back your results.
1. wait until the ghost touches start happening and flip the phone around. hopefully the ghost touch continues to happen in the same exact location of the physical screen, and it triggers a different button
2. remove the screen protector and try the tests again
are you using a screen protector?
might process a warranty replacement if the results are reproduceable

Oh, that is good to know. I'm not using the dual-screen attachment anymore (typing in portrait mode is IMPOSSIBLE with it), but I only ever used the Dual-Screen notification shade tile to enable the second screen, not the pill button thing. I should have explored our options more thoroughly. Thank you for correcting me.
Edit - I have recently added a tempered glass screen protector to my phone, and while it completely screwed with my fingerprint biometrics (I had to delete the fingerprints and redo them), the protector itself is not causing any ghost touches for me. And once I redid the fingerprints, there have been no further issues there either.

Yes I am using a screen protector and I was actually thinking that might be the problem, although it seems like a solid install. I just got the update for cod season 6 and I'm downloading now. I'll see if that solves the problem. I'll also try what you suggested and then post results
Update: so the cod update did not fix the issue, but I tried doing as you suggested and flipped the phone around and the problem went away. I then tried flipping it back to original and problem persisted. I think it is the tempered glass. I don't want to remove it since it cost me 40 bucks. Any suggestions?

So I installed the update for cod and it still had the ghost touch problem with the top right side of the screen, iflipped the phone per what jd254 suggested and I didn't get the phantom touches. I'm assuming it is the tempered glass that is causing it. I dont want to remove it cause it cost me 40 bucks.
2nd update: so I tried taking it out of the dual screen case and notice it doesn't have phantom touch ( I played a full game of battle royale) so I'm not sure if its the tempered glass or the case. Need to investigate more

Is the case touching the tempered glass anywhere around the the edges? If the case is pressing on the screen protector and lifting or peessing it even the smallest amount that could cause phantom touches maybe..just an idea
FWIW, I'm using both a tempered glass screen protector and a case that wraps around to grip the front of the phone a bit, and I'm not getting any phantom touches at all.
The case is NOT rubbing up against the edges of the screen protector, however. Which is fine, because if it were, it could potentially dislodge it.
Or, I suppose, cause phantom touches.

Ok more investigating and playing codm I notice that the mini map opens up when i perform a touch combination with my thumbs. So the map gets triggered when I press and hold up on the left side virtual joystick to sprint and press the jump virtual button on the right simultaneously. I can't recreate what button presses open the voice chat box, but now I have to strike the dual case as being the problem along with the tempered glass, at least i assume those aren't causing the ghost touches.
For anyone having touch issues, as a troubleshooting aid: enable developer options, and then toggle on "Show touches" and "Show touch data". Might help figure out what is going on.

I'm getting VERY interesting results.
1. dead spots: I moved my finger up the right side of the screen to look up. my character did not look up, which I would assume there was a dead spot before. This is incorrect. I can see the screen registered using that option mentioned above. the screen registered the action, but didn't pass it to the software?
2. FPS drops: I assume it's an FPS drop because everything was laggy when this happened. (PubG mobile was set to max settings, and runs 100% fine, until now) I was flying the helicopter, so I had several fingers on the screen at the same time, with a lot of rotational movements. the screen doesn't clear all of these movement data until I literally take all my fingers off the screen for half a sec. When I did that, it stop lagging.
3. ghost touches: Each touch on the screen has an x and y axis point to tell the software where it's being touched. With several finger on the screen (sometimes 2, but commonly with three or more), I noticed that the y axis for my left thumb and the x axis for my right thumb was creating those ghost touches! The screen would combine the x and y axis from different fingers to create a touchpoint on the screen.
so I don't care too much about 1 and 2, but... what can I do about 3?

Yeah I noticed a combination of touches triggers the ghost touch on call of duty, I could also be having the combinations trigger ghost touches in other game but I need to test more
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.
