Touchscreen Issues - Sony Xperia X Compact Questions & Answers

Hi everyone,
I finally updated from my Z1 Compact, and have experienced some touchscreen issues with my X Compact.
Top left corner ("back" in most apps) needs a lot of pressure to react
swipe-behaviour is sometimes erratic, meaning it only registers a very short swipe or a touch.
I get ghost-taps on the navbar, but only the navbar, and only when tapping. When I touch one button, sometimes I get a simultaneous touch on a second. Back and taskswitcher has happened, so it's no proximity-thing.
These problems mostly happen when using light touches. When I press very deliberately, like my granddad, it works. I'm a bit disappointed. Does anyone have similar issues? Or no problems at all? And if so, what ROM are you on? I want to find out if this is a software problem, a batch problem or a systemic hardware issue.
I'm on 34.1.A.3.22

XDA Mini (Wizard Screen Issue)

My XDA Mini has a screen issue.
Only part for the screen (the middle) has stopped responding to the touch pad.
How do I fix this, has anyone else had it?
Cheers
Max
My Wizard (O2 XDA Mini S) has just developed this problem. The touch screen does not respond to touches around the middle of the screen. The outside edges of the screen work fine however.
I've had it for about 4 years now though, so I suppose its lasted well really. It's a G4 and I installed a WM6.1 ROM on it about 6 months ago (which is awesome btw, makes the phone sooo much better / faster!) but I don't think this is related to the problem.
Any known fix for this? I think it's a hardware issue since I also have the problem where upon opening/closing the keyboard, the screen goes white with multicoloured vertical lines and the phone emits a high pitched noise (have to put phone into standby then wake it up again to resolve). This, whilst annoying, I can live with, but not now the middle of the screen no longer responds to touches
I read somewhere its to do with the ribbon cable that connects the screen and main board, its gets trapped or worn over time as the keyboard is slid in and out. So I guess the touch problem is a more severe symptom of this? Can it be fixed?
Also a point of interest is that I keep the phone in the case a lot of the time. Could the magnets have possibly affected the screen? Anyone else with this problem keep the phone in its case a lot?
Thanks in advance,
Jamie

Touchscreen issues

I'm having some weird issues with my touch screen. I'm using the Touch Keyboard input method so I can use my thumbs for typing instead of using the stylus all the time.
Very frequently, when i use my thumbs to push buttons near the bottom middle or bottom left of the screen, the start menu auto pops up! It is absolutely driving me mad! I tried to recalibrate the screen, doesn't help. I tried to take off the screen protector and try again, no difference.
Has anyone else has this happen?
Hi,
Yes, it's a common Problem with the Trintiy.
But be happy, that you don't have these Problems.
I have heard, that there are Problems, when the device heats up and the casing pushes on the top-left corner. But with my Trin it only occurs, when I'm tiping something and push a little bit to hard in the middle of the screen. But it doesn't disturb me too badly, as long as it won't get worse.

So it's more of a design issue than anything else? Damnit! I was hoping there'd be some sort of fix or that it was just my phone that was defective somehow.
Sigh, I've never noticed this problem until I started using the soft part of my fingers to type.
Anyways, thanks for your reply.

touchscreen unresponsive after opening slide cover

Hey guys,
i noticed something strange on my tn7.
Sometimes (maybe 50% of the time) when i open the (original) slide cover to wake up the screen, the touch screen is very unresponsive.I can touch, but it notices only ~10% of what i am doing and is extremly laggin. when i then turn off the screen with the button and turn it on with the button again, everything is fine.
Also when doing this i have to wait for the screen to go off completly - if i wake it when the backlight is still on but the screen is black, the issue stays.
This never happens when i wake the tab with the button though, only with the slide cover. Thats what is kinda strange i think..
Anybody got an idea on how 2 fix this?
Running rooted Stock Kitkat.
Thanks
This is a problem that has existed since this tablet was released and persists still to this day. All you can do is cycle the screen off/on with the power button, unfortunately. Seeing as how this hasn't been solved in the last 10 months and Nvidia is showing signs that they're abandoning this tablet to focus on the Shield Tablet, it will probably never be fixed.
Screen lag
I have a similar issue on mine. I've had mine now about six months and it's very intermittent but at certain times, especially when the battery is low, the keys down the left side lock up and become unusable. I bought the tegra note 7 because of the stylus which I prefer to touching the screen with my index finger, but I don't much like the stylus itself which could have been made of better materials I think. I also find that sometimes it doesn't register clicks, then it will be perfectly ok for a little while. I had hoped with the tegra 4 and the much hyped stylus it would be very responsive but it's inconsistent. Anyone else recognise these flaws?
I also get this intermittently but only ever when waking it up with the cover, its never happened when turning on with the button. When it does happen a quick off and on with the button resolves the issue

Missed thumb touches

This is a strange one to me. I've noticed the phone missing touches when I touch the menu or share buttons with my thumb as those menus won't open and respond. Sometimes it will work properly 10x in a row, sometimes touches are missed 10x in a row. I have show touches enabled in the developer options so I can also see touches being missed that way too. The strange part is this doesn't happen when I use my finger, it properly registers touches in those locations every time. Has anybody else noticed this? Can anyone provide insight as to why this would be?
Hey, I noticed this aswell... Tried with multitouchtester, but everything looked Fine...
The top right of the screen always used to give me trouble too.
Yeah, this issue pretty annoying to me, but at least there appears to be a workaround. I am wondering if this could be due to a firmware issue and if it could be fixed with an update?
To me, it is the top left corner. It is not severe but it is there.
Coming from Nexus 5x which had same problem after an ROM update, I hope it gets fixed in future update as in the case of N5X.
Not getting this issue at all. Running on 58.019S

G4 Digitizer problem?

I have a Moto G4 that has had the touch screen become very erratic lately. This issue appeared shortly after a factory reset. The phone is stock, recently OTA updated to NPJ25.93-14.7. It frequently freezes and won't respond to touches of apps or the home/back/recent buttons, and won't side scroll to the next screens properly. Sometimes random apps launch on their own without any touch, and if you try to quit them with the back button they keep relaunching. The problem is intermittent.
I activated "Show Taps" in Developer Options and when the problem is happening there is a tap dot near the lower right side of the screen. It bounces up and down a little bit and vibrates sometimes. When this dot is visible tapping on anything else like app icons or buttons usually has no effect, however the taps are shown on the screen. If I hit the power button to make the screen go black it will sometimes recover when I reopen the display, other times it takes a reboot.
Wondering if it's a hardware issue, a guy at a Verizon store who seemed to know more than most said it was a faulty digitzer--it's seeing touches where there are none. I've replaced displays successfully before, would just like to have a confidence level that the digitzer is really bad before doing that, as opposed to a software or other hardware issue. Any ideas about problems that might cause this problem, like other hardware or a corrupted OTA? Seems very hardware-ish to me, but I'm no expert.
I have Drive links to a couple of short videos on the symptoms, can send links. Much appreciate any insights.
Mine has that issue as well. It will spam the 9 key on the unlock screen or anything in that spot if an app is open or what is on that spot at the home screen. I have to double unlock the phone to fix it. I guess turning the screen on and back off resets it for that session. But it's mostly every time the screen goes dark and comes back up I have to turn the screen off and back on to use the phone.
I had a similar problem and was able to send it in under warranty and get a replacement phone
G4 Digitizer or ghost touch
Apparently this is called Ghost Touch issue, and affects many phones. One solution tried is to disable Battery Optimization for System UI and Google Now Launcher in Settings>Battery>Battery Optimization. That seemed to cure it for a week or so, but the problem returned today. I can sometimes recover form it by hitting the power button to blank the screen and then reopen. Other times it requires a reboot. I see all kinds of alleged solutions out there from dimming the brightness to removing tempered glass protector to using a slow charger, but those don't seem like real fixes but workarounds (if they even work at all). Any other ideas?
