My phone is having some sensitivity issue. When laying flat on surface or sometimes holding my phone with one hand, the screen will have intermittent touch.
E.g. unable to scroll the page instead it will click to the screen. Is there a way to increase the touch distributor sensitivity like Samsung phone? Or it is a hardware issue? Thanks

My TF700 has recently developed erratic touch and screen behavior when docked.
Symptoms: Jumping screen - the image at times bounces around slightly
Phantom touches happen when touching the sceen OR the BACK of the tablet, and less frequently, when not touching the screen, but when holding the tablet where the screen angle may be moving slightly back and forth.
Sometimes, as well, the tablet does not respond to the keyboard. Changing the angle will sometimes remedy that.
It appears that this only happens when docked and may have to do with movement of the angle of the tablet in the dock. The problem seems to go away if I move the tablet/dock angle more vertical AND support it in the back to keep it from moving back and forth.
My unit is too old to be in warranty. At one point one of the plastic clips on the connector broke and I used epoxy to fix it. I also noticed that at one point, pushing the tablet back to too oblique an angle would actually cause the case of the dock to separate slightly.
It might be possible that some of the "phantom" touches that have been reported when a tablet is sitting untouched are due to vibrations in the room (walking etc) causing the tablet to move the docking angle sufficiently, resulting in the issues here.
Any ideas on how to steady the dock/tablet connection?
sounds more like your touch screen is failing, your fault desciption sounds just like mine did before I changed the touch screen and the issue has now gone away

Update- Found a "fix" for now
EDIT: I ended up using self-stick velcro, just the fuzzy side. I put a 2 inch strip behind each hinge. The fit is quite tight, but that is what I was aiming for. Tablet is behaving OK.
I tried using my son's keyboard dock and the problem did no occur. It had considerably less play in it as well. I have temporarily concocted a fix -- I put a strip of material (a thin velcro tie wrap, because it was handy) along the inside back of the dock hinge before inserting the tablet. This tightened the connection sufficiently to keep the strange behavior from happening. Gotta come up with something a little more permanent, though. I'm thinking of trying label tape (like TZe Label Tape) until the thickness is right.
On previous S phones, there was an option to turn on sensitive screen. In my s7, there is no such option but it seems like it's turned on. It registers touch even if I don't touch screen (from 1-2 millimeters away). It's so annoying.
Plus, it registers my nails as touch, s6 wasn't like this.
Anyone find this annoying as well?
I'm rooted, maybe there is a way to adjust it.. Please let me know if so.

I'm having the same issue. If I put the phone in my pocket with the screen on it registers touches from the fabric of my pocket. I've never had a phone register touches to that extreme. Screen is very sensitive. I keep hitting the back button also which is really easy to fix and pisses me off Samsung hasn't done it yet.
It took a few days for me to get use to the extra sensitivity vs Nexus5x. Keep using it and you won't notice after few days.
I have the regular s7 and the sensitivity is driving me nuts too. I keep bursting photos since the camera thinks I'm still pressing down when I lift my finger up. Using the phone in general makes the phone have a seizure. I hold the phone with my left hand and scroll with my right, but I can't grip the phone without the fleshy palm bit under my thumb and my fingertips touching the screen since the bezel is so thin. This makes the phone go crazy since so many parts are being touched at the same time. If I change the way I hold my phone in any way, I know I will drop the phone, especially since my hands are small.
I'm waiting for a case to be shipped to me, so hopefully that will help stop my fingertips and palms from touching the screen during general use.
Still, this is a problem.
I too have noticed that the sensitivity of the capacitive buttons (mainly the back button) is waaayyyyyy too high. I'm finding that when my thumb isn't even touching it, but just hovering over it, that it activates the back button. Also, when scrolling through pages, I've noticed ghost button presses of the back button.
The only thing I agree with here in touching the screen while gripping it.
None of the other stuff at all. Not even a tiny bit.
If you can press buttons and control the screen without touching it you are part way through your padawan training.

Capacitive buttons are OK, only screen sensitivity is too high for me. Strange.
I am having problem with my touch screen it is not sensitive enough. Any idea how to make it more sensitive?
I feel like it is way too sensitive. I can't even hold my phone in one hand without activating apps that are on the right and left sides of the screen.

Get a case, same was happening to me, the bezel is too thin along the sides of the screen, I got this one, never had the problem since

I dropped my opo today from chair, everything is fine no dents at all but some portion of screen the touch doesnt respond. Installed some apps and verified. Please check pics the 1/2 inch horizontal portion across the middle of screen. Is that a hardware issue / need to replace touch or digitizer?
Hi all, this is a bit of a long one.
tl;dr - I'd like to improve the fingertip performance of the Shield K1 I purchased recently, which frequently drops parts of swipes. This issue becomes worse when a screen protector is applied, but is mitigated under certain stylus situations, when plugged in, or when 'grounded' against the body of the user...
The screen frequently 'drops' swipes (the path is broken during the swipe) with 2 or more fingers on the screen, when a screen protector is applied (tried both plastic and tempered glass). It also does this when there is no screen protector applied, although far less often.
This makes the device unacceptable for touch-based rhythm games like VOEZ, Cytus or Starlight Stage, or for MIDI/OSC apps with sliders.
The performance is at it's worst when both fingers are near aligned on X or Y axes, and is apparent on apps like "Yet Another Multi Touch Tester", where rubbing the screen with two fingers aligned on the same axes will cause the touches to drop and swap IDs repeatedly. The issue is not apparent in casual use apart from the errant swipe changing directions or not having the right amount of momentum.
Performance improves significantly in a few scenarios:
Unit is plugged in to charge
Unit back is in contact with user (resting in lap, held in another hand)
With Stylus touch blocking disabled, direct stylus 2 is touched to screen during fingertip input, then swapped for a finger (???)
Based on the last point, the device seems more than capable of reliable reading of fingertip swipes, but only after the stylus has triggered some kind of change??
I've tried the included About Tablet touch calibration page, adjusting the touch pressure scaling in the touch.idc. Based on the touch.idc, I assume this is an Atmel Maxtouch digitizer, but I can't find much information on how these would handle screen protectors. They do seem to be able to read touches before contact is made with the screen surface, but I cannot find any way to increase the sensitivity to this point.
I have a Nexus 9 which shares the same Nvidia Tegra K1 chip (albeit dual core, 64-bit), and uses a Synaptic DSX touch screen, that has no such issue even when 2-3 screen protectors are applied at once... of course, this digitizer will not read the directstylus 2.
My main goal is to try and get this touch screen reading fingertip swipes accurately, even at the cost of stylus support etc. Does anyone know of any ways to adjust touchscreen sensitivity to account for dropped swipes like this? Are there any tools for debugging Android's reading of the touch screen at system level? I'd really like to know what the stylus is doing to improve sensitivity...
Any update on this?
I'm also having the same problems with the shield k1. It's especially apparent when my fingers get a little sweaty. The only fix I have so far is to keep them absolutely dry. I sometimes use powder on my hands and will go to the extreme of using latex gloves just to get the touches to register correctly. If you find any other solutions, please update this post.
