SOLVED:
It's a hardware issue. If you have this problem, ask Sony for a screen replacement.
Sony replaced a new Z2 for me, now I got no more touch issues.
Manufacturing Date:
My previous Z2: 14W20 (with bug), @gamer649 with 14W28 has bug too
My new Z2: 14W33 (without bug)
However, @mariosraptor with earlier batch 14W17 reported no bug.

Firmware: Xperia Z2 running 17.1.1.A.0.402 and latest 17.1.2.A.314 firmware (previous firmware I'm not sure)
Bug: Glove mode randomly turns on, but in display setting it shows off.
Details:
This happens all the time. Screen sensitivity increases as if glove mode was turned on. But glove mode is actually showed as off in display settings.
Findings: After several days of testing. I found some interesting things that may be helpful:
- 100% bug appears upon launching a game call tower of saviors (by madhead)
- 50% bug appears upon launching keyboard in messaging apps (wechat, whatsapp, fb messenger)
- 50% bug appears after redirecting to messaging apps from notifications drop-down.
- Sometimes it got resolved by pressing the app drawer icon from home screen.
- Not caused by root because bug appears after reflashing firmware.
Temporary workaround: Turn the display off and on. Usually last no more than 1 minute before this bug reappears.
Failed solutions:
Not working steps:
1. Turn glove mode on and off.
2. Turn off tap to wake up.
3. Reduce and increase screen time out.
4. Apply and remove screen protector and tempered glass.
5. Turn x-reality on and off.
6. Turn auto-rotation on and off.
7. Turn smart backlight control on and off.
I also tried all these:
1. Use PC companion to do a phone repair. (bug remains)
2. Using the phone, I did factory reset + erase internal storage (bug remains)
3. Using the phone, I did a factory reset (bug remains)
If you need any info from me I'm happy to provide. This bug is really annoying, it causes unwanted touches and keyboard typos.

- i had ghost touch issues most on 402 firmware most
-tried 55 which i had this prob, 69, 438 and 402 i had
-CM11 didnt seem to have this issue
try flashing CM11 or something non stock based, if it still happens then we can conform its a Stock Rom issue
(i dont have a Z2 atm so cant test for you)

I will only go as far as root. To flash CM11 i need unlock BL right.
I got an idea to disable glove mode and see if it helps.

The new 4.4.4 firmware still has this bug! Looks like we need to bring this up to Sony's notice.
I am facing this problem, too.
Got this problem shortly after i bought my Z2 from time to time, mostly while playing Ingress. Than I dropped my phone and had to replace my screen (cracked). The replacement display went totally mad after a few days, I had ghost touches everytime even while the device was lying untouched on the table, the device was practically unuseable. (See video HERE). The repair shop replaced the display again, and it went back to "normal" with ghost touches as described in the first post.
Here's another thread about this issue.

Yup, after update the bug still there. Now I reverted back to 4.4.2 (at least root is possible)
I wonder if this is a bug of Sony or bug of game. But since many are facing it too, I think it is Sony.
In my Z2, I can recreate this bug by running a game call Tower of Saviors.
Immediately after opening this app, the bug will be there.
But after some time being outside the game (display remains ON) the bug went off but easily recreated.
This problem causes me to type wrongly almost all the time.

Some devices have more sensitive touchscreens which cause ghost touches, its a manufacturing defect
I found mine does this after being staticly charged by something, clothing or anything else that would cause static, i just touch my phone on a live and it just removes of that odd buzzy feel and also my ghost touches ???
As for 4.4.4, its not rootable but pre-rootable or even rootable via flashing if you know how

You have no idea regarding the problem we are talking right now.
It's not sensitivity issue, its not a touch issue after all, its glove mode being activated somehow all the time.

i had a simular issue but since i went and Reset my phone via flashtool i havent had it. it only happpend on 402 firmware
Does it show where it is touching? Because glove mode shows with a dot. If doesn't than it is ghost touch. If it does then yes glove mode automatically gets enabled.

It doesn't show the dot but I can tell its glove mode, the sensitivity is same as if glove mode is turned on.
I think that dot will only appear if you turn the glove mode ON in settings.
For this problem, I suspect the device is using glove mode sensitivity values instead of normal sensitivity.
I guess there's a touch profile for glove mode in the system, and some apps somehow tricked the system to use that.
Therefore, there's no dots/rings when we hover our fingers.
I got one game (Tower of Saviors) which 100% triggers this situation.
Mind trying on your devices?
I will try it lAter on.
I can recreate this bug most of the time by opening Facebook app or opening keyboard to type on whatsapp message box..
As said earlier, Glove mode is off.. But still the touch has been registered just like we are on glove mode by hovering the fingertip just above the screen... It doesn't shows the boxes when we touch.
I tried to bring this to Sony's notice by posting on their support forum. But nobody supported it or acknowledged it.. So obviously they have ignored. I request all of you who are having this problem to post on Sony's support forum so that we can bring it to their notice. Or else this will never be fixed.

I posted this issue long time ago, no help too.
I even emailed Sony about this but they say it should not be happening on fully working Z2, and ask me to go to repair centre.
LMAO, what can repair centre do? Deploy an software update on the spot? Idiots.
Anyway, I don't expect 5.0 update to fix it too. Unless someone can get their attention.
I'm wondering why many users don't have this problem. My unit is one of the 1st batches.
Mine is from 14W20... Looks like only few handsets are having this hypersensitive problem(Or people are not noticing it).
Anyways, one of my friend will be buying a new Z2 in coming days. I will check in his device.
I downloaded the game and it worked fine for as long as I played it. I even made a screen record to see while I changed to glove mode. Uploading it to YouTube. Will share link.

Are you trying to prove that the bug doesnt exist?
Hello Everyone. I have my new Samsung S6 Edge about 3 weeks now. It worked flawlessly the first week and a half but lately I've been getting an intermittent problem with the sensitivity of the touchscreen and it is very annoying. I have to swipe, touch a letter (if texting), or touch an icon, multiple times before it will execute the touch. Sometimes it seems as if it is in slow motion where the execution responds 4 to 5 seconds after the touch. There has not been any new software added and I always close out of any running programs.
I have tried all of the following to which none had any effect:
a) Restarting the phone by using the on/off key dialog box
b) Shutting it down for a couple of minutes and starting it again
c) Using Samsung's method to restart the phone by holding the on/off key and down volume key simultaneously
After a day and a half of frustration I was ready to take it back to my mobile supplier when it all of a sudden starting working properly after checking to see if my phone volume was at the maximum volume by hitting the up volume button. It worked well for about 3 days and then started to do the same thing. So again, I played with the volume down and up buttons until the touchscreen sensitivity worked.
I'm currently having the same issue again which prompted me to post this message. Playing with the up and down volume keys seem to help it at a ratio of about 7 out of 10 times. I've searched the web but haven't found anyone else with the same issues. A look at the Applications Manager under Running apps, System is taking up 1.1 GB, Apps taking up 530 Mb, leaving 0.99 GB of free memory.
Any suggestions? Maybe I should be taking it back for a hardware replacement?
Thanks for listening.
OK, so now I've come to the conclusion that hitting the volume up key was just a fluke although It seemed to help sometimes. S6 touchscreen returned to normal again yesterday afternoon. It just comes and goes which makes it rather difficult to show a mobile technician. I'll have to wait until it malfunctions again before taking it in to a Samsung Repair shop.
Me too....
I have subscribed to this thread, in hopes of finding some clues, because I too, have noticed the same exact behavior that OP described and was searching for a remedy/explanation. Also, had the volume up and seemed to somewhat fix it, but like OP said it is sporadic. I, by accident in trying to clear the cache, completely blew away my phone and had to rebuild my phone as I had before and even after a complete reset, I still have the same behavior.
Hi Chris, I stumbled across another interesting behaviour. While the phone is acting up, if you press and hold the UP Volume key (keeping it depressed) you will be able to scroll and press icons as normal. As soon as you let go of the volume key, the issue continues.
This is a link to a video I uploaded today to You Tube that shows exactly the issue I am having.
w w w .youtube.com/watch?v=vkfaxILs4VQ&feature=youtu.be
Just saw your vid, looks like yours is more pronounced than mine (non-Edge btw) and happens once in a while and then it goes away - I am hoping it isn't progressive. I can't seem to identify what triggers the sluggish behavior. I typically clear all apps from the recent apps as a matter of my normal operation in all my previous smartphones. When I notice it the most is when pulling down the notification center and either nothing happens or I have to pull down the shade all the way down for it to stick, otherwise it slides back up.

for me it's much better..still think it's also the memory problem..as around a half day all is fine..than the lag starts..
Took the phone to a Samsung Repair Shop today. Turns out the LCD display was malfunctioning. It took them 1.5 hours to repair and replace under warranty. Hopefully I won't have anymore issues with it

thx bro
Yes, I did that same thing, and it did help a LOT.. however after the latest update (I have the Edge+) the issue returned.. did it again, and it "fixed" it, but for how long?
And why is this happening??
got the Hardware Info app it is called VIDEOCON ALPS X301
I'm thinking of putting a software ROM on the phone and saw this section "slim roms".
It's a pretty low end device and lags like hell when I load Facebook in browser (I have 5000 friends, which is probably why). Can't find specs on this device anywhere either.
One thing that bugs me is the proximity sensor does not work correctly. For example, if I'm in a call where it requires interaction (such as pressing 1 for this or 2 for that) when I remove it from my ear I have to press power to to turn the screen back on, navigate through 3-4 different menus (it's quirky too) and get back to the dialpad to press my choice.
I'm looking for a suggestion of a useful slim rom to reduce memory usage and possibly alleviate the problem with the hardware proximity sensor.
Thanks
this phone does not have a proximity sensor
Settings accessibility enable power button ends call and then disable it that's the only solution I found for the problem

Unfortunately, you aren't going to find much info unless you produce it yourself for that UMX brand. Budget Mobile no longer offer phone service and you'd have to unlock the phone on another carrier [which can be done nowadays luckily].
I've been stalking this forum for a few years now, from back before all the pop ups, but for the first time i'm stumped. Here's the rundown: i broke my pixel 6. not terribly heartbroken, the phone is ****, everything it does "well" is only moderate on any other phone i've owned.... sorry, digression. Anyway, screen is completely black and unresponsive to touch. screen is locked with 6 digit pin. I know the pin. but i cant enter it because the unresponsive screen. Phone gives haptic feedback when a wireless mouse is plugged into a multi port adapter, which i bought intending to plug the phone into an hdmi port... but back to the pixel 6 being a ****ty phone, i have to install an app to do so, since the phone doesn't do it natively.....which i cant do, because it seems that while usb debugging may be on (adb detects the phone) i cant authorize the computer.... even though ive done it a hundred times, always clicking "always allow from device" sorry, digression again. i just want to get my **** off of this phone. guys at cell phone store are either incapable or incompetent, because they say they need touchscreen access. i have otg adapter, multiport adapter, wireless keyboard/mouse....can anyone help me?
EDIT broken phone has to go back to the insurance company in....6 days

you see my dilemma?
You may be able to project your screen with a wired dock (see https://support.google.com/pixelphone/answer/2865484?hl=en). By following the directions and begging for or borrowing a USB-C dock from someone, you should be able to get your stuff off your device, especially as you can connect a mouse to the dock if touch doesn't work.
The other alternative that may work for you is to go into fastboot (long press power to shut off the device, then press and hold volume down while pressing and holding power) and use ADB to backup your device, including the storage. See https://www.technipages.com/how-to-backup-your-entire-android-device for details, and pay attention to the -shared flag.
Hi all.
The LCD of my A52s is broken. Android 12
I wanted to make an Backup but I cant access the files unless the display is unlocked.
I have registered a pattern and a Fingerprint.
Tried to use fingerprint : vibrating but not working
Tried Samsung Find my mobile to unlock screen : Not working, says "Remote unlocking is deactivated"
What are my options if there are any?
Dont want to root it.
Thank you in advance.
//edit :
Not sure if USB Debugging is enabled.

Mouses are relative positioning things. That makes life more difficult.
A digitizer pad would be better, but those too do a bit of panning.
You want an absolute pointer device.
I had an old hardware project that I just updated and used to debug some media commands.
It uses a serial port from a desktop that feeds a µC that is a peripheral to an Android over OTG.
So you can put absolute positioned clicks into an unrooted, non-ADB device.
But it seems to have a bug now. I have to look into it.
Dumb question: Do you need to swipe to enter your password or can you just click?

Yeah, I've never used it so I didn't know if you could just tap the dots in succession along the path.
Not a big deal or difference, if I could just get the HID report descriptor working.
Edit: Ah, got it working. Android doesn't seem to like it when a USB peripheral is a keyboard, consumer control, mouse and digitizer.
So I took the mouse out.
Did I guess your swipe pattern?
Do the swipe dots appear in your login screen centered exactly vertically?

It looks like this =)
Thats not my display by the way.
When I try to use the fingerprint, it vibrates but the phone does not recognize it.
It's kind of pesky that the aspect ratio, the vertical position and the scale of the layout are all a bit variable.
At least the aspect ratio is a solid number. Height in pixels/Width in pixels. I make yours to be 2.18?
Too bad you didn't try to do this when your display was working!
My setup works fine, but that isn't really going to help you any at this stage.
I was thinking of getting a separate Android to use as the "digitizer" but that means getting a Linux USB HID gadget working.
That looks like a bunch of work and moreover it's not universal for any Android.
So, I don't know that this is going anywhere. It's even possible your device locks out USB OTG when you're not logged in.
That's easy enough to check, just use a OTG adapter and a USB device with a LED, flash drive, mouse, keyboard...
If you can borrow a Wacom tablet from someone that might operate in absolute coordinates.
The problem is, it can operate in relative mode too and without the Wacom software installed you won't be able to switch it.
The last Wacom I had just plugged into Windows and operated as relative.
https://support.wacom.com/hc/en-us/articles/1500006340122-What-is-Absolute-Positioning-
Unless you have an ATMega32u4 and a UART I don't know what we can do.
The Raspberry Pi 0W could do this too, but I'd have to write all the code for it.

I really appreciate the time and thoughts you put into this problem.
But -> "no backup no sympathy"
I was my fault not doing a regular Backup and so I guess the data is gone. I might just let samsung change the display and hope they wont reset the device.
It's too bad you're not local. This would be a piece of cake.
It's actually so much fun watching this thing login.
I wrote a cleaned-up Windows program for this. Now the command is:
Code:
C:\>swiper /c3 /a2 /y0.683 /u 791364
The "password" uses the position of the digits on the keypad.
Unfortunately I've never done a deep dive into the whole encryption of /data
Is there a TWRP that can decrypt? Does that require swiping too?
I dunno, I might be able to mail you a RPi0 with code on it.
Still, if you didn't leave ADB on, it will be a big pain to enable it.
You could also buy a replacement screen and just connect it up floppy-wise without removing the old screen.
Sometimes the most simple ideas are the best.
We used cling film on the same model and painted dots on the film where the pattern is.
Put that cling film on my phone and swiped my pattern. After a few tries it unlocked.
Using my fingerprint wasn possible.
Oh! I thought that the touch screen itself was non-responsive.
I had presumed that you had unlocked it enough times that you could unlock it without looking.
In any case, I've had fun with this. My new secret unlock pattern is:
This has maximal pointyness and requires coordination to swipe between the dots without catching the wrong ones.
If they only gave us a choice of 4x4 or 5x5 we could come up with a pattern that a human couldn't do!
