Ok, so I thought I was having a touch sensitivity problem on my Nexus 4, because often a touch or a swipe would go unrecognized...
Then I realized I was noticing it especially in these two situations:
-Turning wifi slider switch on/off
-Swiping back to a previous tab in chrome
Turns out, what was going on was when I reached that far with the thumb, my palm was touching the curved edge of the screen, making it think I was already touching with a different finger. This "numbed" the screen from my intended touch until I shifted my hand slightly, releasing the unintended multi-touch situation. This made the issue seem sporadic.
I am not saying this is what all other people are experiencing, I am just putting it out there in case someone else is unknowingly doing the same thing. I could also imagine typing errors on the far side of the keyboard for people with certain hand shapes.
It seems almost unavoidable due to the thin bezel and rounded edge, but I would think problem could be avoided with some clever "palm touch near edge" recognition code, but until then I just have to get used to not gripping the phone so tight.

I think that might be the case also. In some instances, it seems like I can't tap on the screen, but it can swipe and if I reposition my hand, it will work.
My Note seems unable (or unwilling) to detect touchscreen contact within a relatively small margin of each edge.
Using the 'Pointer location' option in Developer Options, I can see that no matter where along the edge I put my finger, it seems to clamp it to 20px away from the edge. Taking the left edge, for an example, I can see the line tracking my finger up until I hit the margin, and then it will go no further left. It is still detecting the press, though, moving my finger up and down will result in a perfectly straight line being drawn parallel to the edge of the screen.
I'm using PA3 (RC3). Either the problem doesn't exist or I just didn't notice on stock. I only became aware of it when attempting to mess around with the new 'Pie' thing in PA, and realising that it's somewhat difficult for PA to detect the gesture when the edge of the screen isn't registering the touch!
I'd appreciate it if anyone could quickly check whether their Note has the same issue, or if anyone is aware of a way of expanding the area on which touches will be registered.

try the touch screen benchmark app found on the play store to know if you have any problem with the touch screen

I wasn't sure to which app you were referring, but I found one that was able to fairly clearly show the issue. I took a screenshot and attached it to this post.
Each of those lines was drawn from or to the edge of the screen. You can see they all stop significantly before the boundary. The app is ScreenTouchTest, if someone would mind repeating the experiment and seeing what results they get!
Same thing happens with me. However, when using the S-Pen, the boundary gets to the right, ie the screen area increases. Here are two screen shots, one with finger and the other with S-Pen.
P.S: sorry for the big pictures...
Dial *#0*# and do a screen test..

Anyone else having problems with the sensitivity on fast scrolling? Seems to not be as smooth or compared to the iPhone 6 and HTC One M8 I have been playing with...It's almost too sensitive or something, I can't quite put my finger on it.
Do you mean the effect where things sometimes bounce back while scrolling?

There is an earlier topic about it here: http://forum.xda-developers.com/z3-compact/help/swipe-issues-t2888154
The phone has an extra-sensitive touch screen because it has a "glove mode", and I'm thinking the effect of the technology for that glove mode isn't completely suppressed when the glove mode is disabled, so the touch screen would still be slightly more sensitive than those of other phones, even when glove mode is disabled.
If glove mode is enabled, the touch screen is so incredibly sensitive that without gloves, it will register a touch when you hover your finger about a millimetre above the touch screen.
I found that for me it helps to use "lighter" and shorter swipes. Also after a swipe lifting my finger a bit higher off the screen than I was used to.
Some people might always have been doing shorter and lighter swipes, hence not everyone is experiencing the problem. It's also been said on the Xperia support forum that not all units use the same glass for the front; some use "gorilla glass", others use "dragontrail" glass. That could also be influencing the touch screen sensitivity/behaviour.
I've adjusted my swiping habits relatively quickly and now I get the bounce back effect only once in a while.
I do hope that Sony comes with a firmware fix to compensate for the over-sensitivity though.

hi, is it normal? happen to my unit also.. quite annoying i can tell.. different with my TX..
Go into developer options and enable "Show touches", perhaps touch the screen a few times then turn off show touches.
Sorts it out for me! I was having a nightmare swiping down to select words in Fleksy.
This workaround will do for me until Sony fix it properly!

I really wish there was a way to turn down the sensitivity. During typing, I frequently have screen presses register as very short swipes, which is incredibly irritating, as I then have to backspace and delete two words.
Not really helping you, but this shows how sensitive the z3c display is:

Touch screens usually respond to metal. The screen of my Z2 tablet does.
My screen is so sensitive I can operate it using my leg... through the pocket. I saw in Z1 and Z2 threads that there is a config file that can be adjusted, however I'd have to root in order to do that, and I don't want to risk losing my warranty (esp. not when reading about glass breaking by itself).
It's not a massive problem -- all it takes is switching off "double tap to wake" and camera launch button. But those are features that are useful. On the other hand, having my phone suddenly switch Torch on, call a random person in my phonebook or reorder icons on the launcher desktop isn't all that exciting either -- not a fan of surprises.
Has anyone else found the Z3 Compact screen too sensitive? (Glove mode is off, obviously.)

On my previous phone (xperia acro s) it often happened that my leg messed with the phone when the screen went on for the alarm going off in my pocket. It was really annoying. I was always afraid that some important settings changed without knowing it.
My screen is so sensitive that I the last couple of weeks only have managed to send a few sms without having to delete several words that are written wrong...!
The speeddialer is also terrible and often leads to wrong contacts...
This phone is by far the worst phone I have ever had regarding these issues!
Is this a sign of a faulty phone or can you relate to these problems as well?
Is there a solution???
My speed dial wasn't working out of the box. Had to make a factory reset, that fixed it. Sensitivity isn't interfering with my writing though. My previous phone was a bit bigger so I had to get used to writing on a smaller keyboard. But why would touchscreen sensitivity be an issue when writing anyway? Are you using a swipe keyboard?
No I'm just using it out of the box settings...? I can see swipe is enabeled but I text normal... I have had to disable autocorrecting words when I write... It is really strange... I have had many different smartphones over the last 15 years and this is by far the most responsive ever tending to be useless because of the many mistakes I make during calls and sms...
I never had any issues what so ever with my M7...?
I have just disabled "motioninput" (roughly translated from danish...) under Xperia-texting and this seems to have helped alot!!!
I'm on the same boat - it's too sensitive compared to my m8. Hoping for update to fix it
You really should try to do what I did and disable motioninput! It really helps ??

I go into running apps and force stop com.sonymobile.touchscreen.touchfilter.tfpss and it seems to be a little better, still sensitive but at least no bouceback. I should try pm blocking it.

I've tried this as well, but unfortunately no change, I still get bounce-backs when I don't use particularly light and short swipes.
Just got my S10 today and I already noticed a big problem. If I try to tap anything near both the left and right edges in the middle of my display, nothing happens or things hang up. For instance, using the Samsung keyboard, I can't press either 1 or 0. It is repeatable with other apps as well.
It seems to be a software issue with the edge panels because it is in the region of the screen that shows the "edge". However, turning edge off has no effect on the problem. Also tried turning on Touch sensitivity but no help. If I go to developer options and enable pointer location, all areas of the screen respond, even the edge area, so it doesn't seem to be a hardware issue.
I took off my case but that didn't fix it either. I could try taking off the screen protector but I'd hate to ruin it if that's not the problem.
Anyone else having this problem? I'd hate to RMA a phone 2 days before its official release lol.
I am having similar issues with my S10+ towards the middle lower right or middle lower left of the screen. I'm sending mine back for a new one. I've tried every fix imaginable and still no joy. Hopefully the new phone will be better, otherwise it might be an issue with the new screens! What a bummer!

Samsung turns down sensitivity on the edge to prevent accidental touches. Try downloading Good Lock on Galaxy Store, then download Edgo Touch from Good Lock to adjust sensitive region.
Try turning off 'accidental touch protection'
Sent from my SM-G975F using Tapatalk
Accidental protection is for dark environment where it prevent touched in pockets. It likely won't be what's causing the insensitivity for them on the edge of the phone.
With Samsung's Edge Touch app, it'll let you adjust the sensitive zone on the edge of the phone.
Please help let me know if screen activating in pocket is a bug or if this is intended design (i.e., design flaw)?
Now that it's summer my leg can get a little sweaty. But my phone in pocket triggers off my leg due to the moisture! Then the phone will randomly edit various things as the phone bounces around in my pocket.
WTF, why won't the phone just detect the darkness and know it's in my F*ING pocket! My S9+ was really good about this, it knew when it was in the pocket and ignored my sweaty leg.
But with this retarded S21 Ultra, it doesn't seem to know when it's in your pocket. I've already lost several important appointments and tasks (my calendar and task lists widgets are on the main screen) because the dumb phone let my *LEG* edit/destroy/delete the important tasks and calendar entries.
I'm holding out hope that maybe this is not how the phone is designed to work, maybe I can fix it by doing a factory reset. But I recall other posts complaining about how the phone is too retarded to detect being in the pocket when it comes to the Always On Display (AOD) and just keeps the display on while in the pocket too. So maybe it's a fatal design flaw of the phone, where if it is hot outside and you have moisture on your leg, your phone will think your leg is typing and just randomly change things.
Please help me understand whether this is a fatal design flaw or just some bug or what!?
please disable the option to activate the phone/unlock phone via sensory detection
i believe you need to deactivate that first from the smart lock - on body detection
and then also go in advanced features, motions and gestures and deactivate lift to wake

Used to happen to me too. Ofter i would only realise phone was awake and messing around by the beeping sounds of the dialer going off in the pocket, or the increasing temperature of the phone against my thigh - screen on for God knows how long.
Pocket detection is dubious at best - doesn't work consistently. All this happened despite it being set to "on"
Turning off double-tap-to-wake screen helped me.
Now the phone only wakes up for calls and will show lockscreen only if I hit the power button (side key) - I have never used AOD, so screen stays off no matter how hard you tap away at the screen.
Unfortunaltely this puts a lot of mechanical wear on the side key (waking up the phone to unlock)
TO solve this, I have set my Fingerprint scanner "always on" enabled, so if i want to unlock phone without wearing out the side key, I just hit the screen with my thumb where i know the fingerprint scanner is, and it takes me to the home screen without showing the lock screen. I've developed muscle memory now and can hit the correct spot on the screen 90% of the time without the fingerprint icon displayed on screen. No perceptible differnence in battery life as opposed to keeping fingerprint scanner always on disabled.
This has worked for me. Maybe you can try it out and see if it solves your issue.

I dont think that would put any mechanical stress on the power key.
Phones are tested for upto millions of press of buttons which you woudnt be able to achieve in your lifetime .
I have my aod on always , and double tap to wake on always .
Best possible way to avoid accidental wakeup is to insert your phone with screen facing away from the body i.e towards the fabric of pants/jeans/lower

Yes, lift to wake was already disabled while the problem happens. The phone still wakes from "taps" caused by the leg.
I want to clarify, the problem is not caused by the phone unlocking or locking.
The problem is because the phone is not ignoring screen taps when in the pocket. It thinks I'm double-tapping to wake the phone.
I'd like to keep enabled the smart lock on body detection, and keep enabled the double-tap to wake. I can see how keeping the phone locked would help, but the root problem is still there - the phone wakes up even though it is inside the pocket.
Keeping the phone locked would just transform this to a new problem - how do I prevent my phone from waking up in my pocket and wasting energy while my leg enters various unlock codes by itself.

Yes, the S21 Ultra refers to this as "Accidental Touch Protection." The flavor text explains "Protect your phone from accidental touches when it's in a dark place, such as a pocket or bag."
Accidental Touch Protection has been turned on when I had the problems.
Does anyone know why Accidental Touch Protection is not working, even though it's turned on?
The setting is found under Settings - Display (scroll down, 4th from the bottom).
Keep the back of the phone towards your leg, problem solved.

Yup, you may be right. Ideally they should last a lifetime. But all mechanical parts are prone to failure. Same thing holds true with charging ports - they shouldn't fail, but often do. Doesn't happen to everyone, but it's something to keep in mind.
I've had my HTC power key fail on me due to constant use over 2 years, and ever since then I've stuck to using the screen for wake-up. Needn't happen to everyone, but once bitten, twice shy, right?
The screen facing outwards is a good idea and it was the first solution that came to mind when I was having accidental wake-up issues. Tried it for a few days but stopped using it because it's awkward for me (camera bump irritates thigh) and it was un-intuitive to take out the phone, then turn it around in the hand to start using it. I just wasn't comfortable using it that way.
Like I said, this set-up works best for me, everyone might have their own way of doing things
All I know is that with this set-up, I don't have any more accidental wake-ups while the phone is in the pocket. That was the main requirement.

If you'd like to keep the tap to wake feature on, then the best solution for now appears to be what @aj7400 and @blackhawk have suggested - Keep the phone screen facing away from the thigh.
The screen of my phone frequently turns on when it is in my pocket and the phone starts performing some tasks like playing music.
Does anyone of you experience the same problem ? Is there any method to prevent accidental touches when the phone is locked ?
Edit: sorry I didn't notice this thread, so I created another one for the same problem. I'll try some of the solutions you proposed guys, hopefully it will fix the problem.
Was there any pattern to when Samsung's "accidental touch protection" failed to keep the phone screen inactive?
I'm trying to find out if there is anything going on that might affect the accidental touch protection. Normally, accidental touch protection keeps the phone screen off when the phone is in your pocket, to protect against unwanted touches or "butt dialing."
But in my case, my leg was a little sweaty and the phone screen activated and deleted some of my important info.
Has anyone else seen anything in terms of a pattern when your accidental touch protection fails to protect against accidental touches?
Maybe you had see-through pants with white pockets with direct sunlight glistening off your sweaty thighs?

Nope. Happened to me in Dark blue denims as well as black trousers.
It's not consistent. Works most of the time but fails every once in a while.
For me, usually I become aware of it when i hear the dialer beeps (somehow the screen taps end up on the emergency call dialer screen) go to town.
Funnily enough, I turned the feature off and was roaming around the city for more than 2 hours. No accidental wake-ups at all. This is even after I have temporarily restored double tap to wake screen. Need to watch this for a few more days and if i don't get any more ghost wake-ups, i'm keeping it turned off.

Have you also tried just initiating LOCKDOWN MODE via the power button before a run?
I'm guessing that your leg and the sweat and the fabric combine to give the electric feel of a skin's surface that activates the phone?
You could also use a Bixby Routine to disable double-tap to wake?

Let us know your conclusion...I went the EXACT ane route (before finding this post): disable ATP and created a routine button to disable double tap to wake when I take the phone out for a walk.
Seems to be working, but it's another source of frustration as my previous Huawei mate 20 pro had the ATP feature but never started playing muzak in my pocket.
Samsung...good hardware plagued by half-baked software.

The Huawei mate 20 has much more major issues than our SK allies flagship phones do in more ways than one
I don't have these issues on the 10+ unless a put the phone facing my leg on the display side.
You should have a good case that has side protectors slightly higher than the display plus end display protection in the case ie Zizo Bolt case. Otherwise a face plant can easily destroy the display. These phones need case protection... before they kiss the concrete.
This also help stop accidental touches both when on and off. It makes the phone easier to hold and use as well.
Face the display away from your body. That should be more than enough...
If it's really still a problem limit display timeout to 1 minute.
Use only the power button or volume control buttons to activate the phone.
-or-
Use a case clip holster.

Well, in conclusion I can only say that the setup is working... Haven't changed anything since then and no accidental pocket mishaps yet. ATP and Double tap to wake are still off.
BTW, your idea of a Bixby routine trigger to disable double tap when heading out to walk is quite neat
