if I plug in my earbud into my note 2, and put into one (not both) earbud into my ear, I can use the cable to swipe the screen.
It's just the way capacitive screens work. The cable in your earphones is conducting some charge and the screen reacts to it as it does with the current in your fingertips.

Try this, hold a metal object between your fingers and try to use the touch screen by tapping the metal object on it. It will kinda work. Try the same with a plastic object and it wont. With capacitive screens, it's all about conducting the tiny electric charge

is the screen heat or pressure sensitive, and how is the multitouch?
Neither. And so far I can't complain about the screen one bit. I do find myself simply tapping the screen to auto-size the browser, been easier than using two hands.
Its heat although the proper name is Capacitive meaning is only works with fingertips or a specialized " iphone " stylus, which i have and dont work very well tbh although mine was a cheapy off ebay (like 60cent for 2)
i just tried one at the store and noticed that it was not as sensitive as the iphone's. if my finger was on the hero light enough there was no response, but no matter how light i try to go on the iphone it always responds.
It is not heat.
Wiki:
"A capacitive touchscreen panel consists of an insulator such as glasshttp://en.wikipedia.org/wiki/Glass, coated with a transparent conductor such as indium tin oxidehttp://en.wikipedia.org/wiki/Indium_tin_oxide (ITO). As the human body is also a conductor, touching the surface of the screen results in a distortion of the local electrostatic field, measurable as a change in capacitance."
And who cares if it's not as sensitive as the iphone? When would you ever try to press a button as lightly as possible in real life? I find it better that you actually need to touch the screen for a button press, leads to fewer mistakes with random light button brushing. I have yet to find a time when the screen doesn't respond when I want it to.
Feels just as sensitive to me. I very lightly ran my finger over the screen and it responded just as well.
Hello all. Yes I am a noob to the forum, but not to small electronics and the dismantling of them. After getting everything set up on my machine necessary to Root my TF and side load the netflix app, I noticed my power button wasn't being as responsive as it should. Doing a quick google search I found that this was a common thing, even on TFs with stock firmware, so I took to dismantling the thing to figure out what is causing it.
I did a quick search to see if anyone has cracked the case open and found this thread. I didn't use a guitar pick, but rather a plastic and metal spuder set I had from repairing my mom's ipod touch (damn soldered batteries!).
Tools:
Tool Kit
Or
A T5 Torx bit
A spudger
#0 Phillips screwdriver.
Lock-Tite super glue gel (optional!)
1. Start by removing the two T5 torx bits from both sides of the charging/dock port
2. Use the plastic spudger or guitar pick and loose the seam around the entire case. If you look closely at the face, you will see the glass meet a black plastic rim and then the metal rim around that. What you are aiming to do is separate the black plastic from the glass. The plastic is glued to the metal so if you see adhesive separating, you are prying the wrong spot. There are various plastic tabs around the glass like a TV remote so using the plastic spuder is safer until you get some visible room to go in with the metal one.
3. Once you have the frame off, there are 4 #0 Phillips screws on the face, one at each corner, then 3 screws on the top and bottom of the frame (previously under the metal case
4. Removing all 4 face screws plus 6 rail screws will allow you to remove the back plastic. Now you can see everything
5. Bonus points for ASUS for giving us a battery that unplugs vs one that is soldered in (damn you apple). If you want some peace of mind, you can pop off the battery cable. I did not see any side effects from doing this (no data loss, etc).
6. On the side with the power and volume buttons, you will see a blue-tipped silver cable under a black tab. This black tab is what holds the ribbon down and lifts up like a toilet seat. It does not pull forward, it does not pop off (unless you broke it), but because it is plastic, be gentle. Once the tab is lifted, the silver cable will come out.
7. Unscrew the 3 #0 Phillip screws holding down the button board for easier access remove it.
-----
It doesn't matter whether you are having a volume issue or power button issue, so long as you know its hardware related. The way these buttons work is under constant pressure is "off" and removing that pressure turns it "on". So the metal tab pushes down on the plastic button, which pushes down on the switch. What is happening is over time, that metal tab gives way to less pressure on the daisy chain and the button stops working. The good news is, this metal tab is just held on via 'wings' around the soldered base. A razer knife is enough to gently lift the wings to pop the assembly apart for repairing. Given the construction of these switches, I wish ASUS just made the entire board available, but oh well.
-----
8. With the offending metal cap off, bend the middle thumb further down and back in to position and re-assemble the switch.
9. (Optional). I bent my tab further in to prevent me from having to re-do this operation several months from now, but doing so meant that ANY pressure on the button caused the metal cap to pop back off. That is really bad if the case is re-assembled. My solution was to swab some lock-tite super glue gel on the bottom wings and base of the metal cap and put it back on the switch. A very thin film is sufficient because it is a gel, it dries in seconds. WARNING> Once you reassemble the switch, keep pressure on the metal cap while you keep pressing the black button. If you don't, any glue leakage will lock that button in place.
Is it only my Note which have an dead angle?
Il attach 2 screenshots how near i get to the edge of the screen.
First on with my finger and second one with my s-pen.
Edith:
Red one is with my hand.
Black with s-pen

Not sure what you mean.
The touch input works only on 97 percent of Notes screen.
The right edge and below doesnt recognize the input.

When I do the Touch and S Pen tests using the *#0*# testing menu on my Note, touch is fine and there is a tiny 'dead' spot in the lower right corner for the S Pen.
In comparison, your 'dead' areas seem quite large.
Well, mine is doing the same, the bottom/right is not working as it is supposed to. Should i get a replacement?
The first picture is for the S-pen the second is for touch...
There is nothing wrong with the screen its the way the software calibrate.
Try changing to left handed and you can write on the right edge but not left.
For the bottom most try turning the screen up side down then you can wrtie on the toppest (bottom) of the screen.
The s-pen is calibrate to be not on the center of the tip of the pen but somewhere above and abit to the right or left depend on your setting (left or right handed).
I went to samsung service center for this. The symptom is worse w/ the charger plugged in.
Their explanation is that the point of sensitivity is not the tip of the pen. The way the pen works is that you can imagine a laser pointing directly from the top of the pen. Therefore, if you want to see how it actually works, write w/ the pen being perpendicular to the screen. The technician showed me and it made perfect sense. However it is kind of strange holding a pen in that 90 degrees position.

Tell the technician to change profession to politician. He can manipulate ppl very good. I have wrote a essay for this issue. I guess your technician is the brother from the guy who did write the spenn programm because he didn't move the point of the spenn tip but he moved the axes of the spenn recognition area. So if you are right handed and you configured your spenn to right hand, you will not write on right and bottom if you left handed you can not write on left side and bottom. I guess the Same guy made the gamma-brightness curve. Send him a MEMO. Because sMemo has a rand and he tested spenn there and it works fine the offset overlaps with the yellow rand on right left bottom sides.
Hope it helps you

Hi,
For all those who have the black screen during call/ windows button not responding issue try this. It is a tech repair, so if you're not comfy dismantling your device take it to a pro.
I've had some spare time to repair an Omnia7 for a friend [ I was acting middle man between Samsung and him]. Sammy serviced the device 4 times and changed everything ( the mainboard, the sensor, AMOled screen) but the problem kept on showing up.
I have traced the fault to the fact that the sensor is pushed to the right by the ribbon attached to it and thus acting wrong. The tape that is supposed to keep it firmly attached is getting weak in time and allows this migration.
Steps:
1. Take apart your phone. Simple job. Remove battery&sim card. Upper cover pops out, 3 screws. Slide out the back. 2 screws at the bottom and the bottom comes off. 2 screws under that cover and the antenna+mic comes off. 2 middle screws for the plastic piece. 1 silver screw for the upper speaker module. 2 silver screws for the mother board. disconnect 2 connectors (1 up for camera and 1 down for buttons)remove mother board carefully ( lift up a bit the vibrator, volume, I/O and camera buttons. they are attached with double sided tape, disconnect the Screen- it's under mb).
2. Take a look at the sensor PCB. I bet it's moved in opposite of the side where the connection ribbon is. You need to realign it. Lift the earpiece and jack. they are connected to the proximity/ ambient light sensor. Should come out fairly easy,it's only double-sided tape. Realign it with in a fashion that leaves at least 1 mm from the side.
There are different ways to make sure the problem does not appear again. Hot glue- just a droplet , piece of plastic, better double sided tape. Choose whatever you like.
3. Reassemble the phone.
Also, see photos attached. Notice how off centered was the sensor PCB
Lol, man its working

Hey guys!
I have a Samsungs s7 edge and I'd like to glue a film on the front part where its no touchscreen. But now I ask myself if the two buttons on the left and right of the home buttons will still work if there is a film on it. So my question: do those buttons react to pressure or to electricity??
Thank you all
It cant be pressure because full covered glass screen protectors cover that area up. Its got to be some sort of electrical sensor
I assume they work exactly the same as the screen itself.
