Hi, this problem happened on my Note 4 too (Cyanogenmod).. and now on my S6 (touchwiz), so I'm wondering if it is app related. Swiftkey maybe?
When I reboot, touches near the top of the screen do not register. I touch the screen, and nothing happens. Towards the middle/bottom of the screen works fine
I have to lock/unlock the phone, then touches at the top work fine too
Anyone else had this problem?
Thanks
Saw this posted here can't remember who it was but i was having problems with my touchscreen missing touches and not working on a flat surface and it solved them
For touch screen problem try this:
-in dialer type *#2663#
-TSP firmware update (general)
You should see "PASS"
Bring your S6 back to Samsung for warranty replacement.

I got nexus s (i9020T) recently and found the touch screen unresponsive sometimes. I've already tried several launchers(adw, lancherpro, go launcher ex), and it seems not launcher's problem. I've also tried to flash different ROMs, including CM-7rc2 and stock 2.3.3, and the problem remains.
Later I tried to bind Multi-touch Visualizer 2 to long pressing home button, and found the when screen is unresponsive, it can still detect press near edges very well, but not the center. While I press at the edge and drap across the center, it keeps tracking my finger correctly. In addition, Locking and unlocking the screen can solve the problem temporally.
I'm confused by the strange behavior, anyone experienced similar issue?
more info from test,
I connect my phone with adb, and tried to "cat /dev/input/event0"
The behavior confirms what I see in Multitouch Visualizor 2: the when the center of screen is unresponsive, nothing can be read from the device node.
I read the mxt224 touch screen controller doc, and it seems the chip features self-calibration, and thus I believe the "lock & unlock" will trigger the chip to tune it self in some way. I don't know kernel very well, so I cannot find the source code Any help please?
FYI. we are not alone.

I got this problem too whenever my phone is in my pocket facing inward.
I have tried to open the calculator to see which part of the screen having problem. Mine is usually the "8" and "5" location unresponsive if my phone stayed in my pocket facing inwards for a certain period of time.
The problem will goes off after couple of mins when i can feel that the phone is cooler than my body temp.
I knew this happens to the Dell Streak as well.
Hey all,
I've had this problem about 3 times now since I got the phone on April 10th. Suddenly the screen doesn't register touches on a certain area. I notice it when I'm trying to type on the keyboard. If I go to the home screen and try to start an app that's on the place where the screen doesn't respond , I can't click it. So it's no keyboard issue. When I reboot the phone it all works fine again. Does this sound as a hardware problem or a software problem?

For the last several weeks, I've been having problems with my touch screen.
It will have lots of times when it doesn't register touch, like when I'm typing, scrolling, or when trying to pull down the quick settings/notification bar, it takes several tries. Also, when I set the phone flat it won't hardly register any touch at all.
I have tried the following to try and resolve it:
- complete factory reset
- changed launchers and keyboards
- making sure screen is clean/fingers aren't cold etc
- changing the long press settings for the phone
Anyone else experiencing these problems? I'm so frustrated, and I'm planning on calling Verizon to see about getting a replacement. Any suggestions would be greatly appreciated.
Had the exact same issue as you and got a replacement and every single issue went away.
Unfortunately I had a defective unit just like yours it was way more apparent when the phone was laid flat on the table and you attempt to make touches
Fortunately I was lucky enough to be within my 14 day return window.. If you're not then it looks like a warranty repair unfortunately.

I have had the touch screen issue and doing the above seems to have fixed it, i will monitor it over the next few days.
I noticed yesterday that the upper left corner of the screen isn't registering touches.
Anything I can do to correct? Maybe my tempered glass screen protector is bugging something out?
Since my bootloader is unlocked, I'm guessing I'm up the creek without a paddle for a warranty fix or replacement?
Thoughts?
Disregard, a restart of the phone remedied... Go figure ?
I'm having the same issue
also having the same issue. restart does fix the problem, but then the issue returns after a few hours. it also does NOT seem to be a hardware issue, as even when I rotate the phone from portrait to landscape, the 'new' topleft corner (previously the top-right corner in portrait mode) will also become unresponsive. seems like a firmware bug or something? anybody have any longterm solution rather than restarting the phone every few hours?
I've noticed that if I rotate to landscape , that previously unresponsive spot on the screen works fine.
I've also noticed that if I tap on the status bar just above it, it works fine.
Very odd! Other than that small quirk, I love the phone!
Same thing
Same issue here.. Corrects after a restart... Other than that it's the best phone I've had.
Issue seems to have been resolved in Marshmallow, or at least so far been running all day without the problem !
Hello guys,
This is not necessarily a specific S8 plus thread, it's more of a software/hardware general related issue. I just replaced my display two weeks ago because I cracked the screen and the display a while ago.
After replacement, I got the phone, everything was good until I dialed *#0*# and started testing the touch. It appears that theres a portion in the middle of the display that is not working (the boxes wont go green when touching them). The thing is that, sometimes, the touch passes this test as in everything is ok and sometimes, it fails.
From time to time(pretty frequent) it randomly freezes and I have to hit the power button to open and close the screen to make it work again.
I just flashed the android Pie hoping a complete erase would fix the thing but it appears it didn't. Do you guys know any solution to my issue besides returning the phone in the service?
Thanks!
