So this weird problem started just this week with my s-pen. When I hover the s-pen over the bottom middle section if the screen, without even touching the s-pen to the screen, it will detect the s-pen and perform the action of the key that's under it. Its really annoying because it will sometimes double tap the key under it like the space bar. It happens when I hold the s-pen about a centimeter from the screen. Could it be that something happened top the digitizer?

There's a few threads on this already, basically what is happening is the rear speaker is slightly interfering with the s-pen's functions. When you pass the s-pen into the area affected by the speaker, the s-pen tells the wacom digitizer in the phone that it is touching the screen even when it isn't.
A few people discovered you can fix the issue with some foil tape wrapped around the s-pen just under the button. That way the tiny magnetic field from the speaker won't affect the s-pen.

Wow. Just noticed something really odd with the keyboard/screen, but then it could be my phone!
If put your phone on a flat surface (ie table) - try type some letters on the right/left/bottom edge - i find it not as responsive as if you typed in the middle part of the screen. But if you hold the phone in your hands, its perfectly fine!
Anyone else getting that weird problem?
Yep
Noticed the problem to.
I'm guessing there is some screen sensitivity changes when it knows its flat on a surface.
I guess its another on the list of things to fix when the release a new build (or some devs release soem cooked ROMs).
I wonder if this is related to the capacitive nature of the touchscreen? I can replicate the effect if the phone is flat on the surface and I'm only touching it with my typing finger. However, if I rest another finger on the device, or hold it lightly by the edges (still sitting flat on the surface) it works fine.
If this is the case, I doubt any rom will be able to fix it since it is likely to be the capacitive touch screen technology and not a software "fault" per se.

I have seen this too. I wondered if it was a perspective thing - are you pressing the right part of the screen?
are you pressing the right part of the screen?

Oh yeah, looks like I am pressing the right part. It just have to be more firmer pressing those edge buttons. It doesn't matter which way the keyboard layout is.
Anyway, thanks to everyone confirming that you got the same problem. I would have thought it was hardware related, but it could be software related I suppose. Perhaps whatever software is trying to rotate the keyboard is having a hard time to work out what direction to show the keyboard is causing that weird problem
Try holding the phone between thumb and forefinger whilst it is on a flat surface and then typing. If I do this, I have no issues, but the second I remove my fingers, I then get the lack of response for the keys on the bottom row of the device.
Regards,
Dave
mines the same may be to avoid key presses in your pocket?
I have the same problem too. It isn't a problem with all capacitive screens as the iphone never used to do this (l know, I know)
So far I've found no solution, let's hope it gets a quick fix
wow, and I thought it was only me, when I put the phone on the desk, and try use my fingers it becomes really unresponsive but when I'v got it in my hand and I'm using my thumb its all fine, hmmm really weird
it's not really a fault, but more of the nature of the capacitive screen and/or software. In comparison with the iPhone, the iPhone's capacitive screen lets you type/navigate with the phone lying on a flat surface. I find that the Hero's screen requires you to apply a tiny bit more pressure and more surface-area of your finger/thumb, for it to respond. I hope HTC somehow tweak the software for this to be more responsive with less pressure/surface-area contact required so it is usable on a flat surface - don't always want to be picking my phone up to use it at work.
i confrim, using hero without touch the metal edge result in less responsivity and difficult on multitouch operation
hope new firmware can solve this, too many errors using it like a normal keyboard on a table!
Noticed the same problem when using the Hero in my In Car Holder. Makes data input into CoPilot very difficult indeed.
A couple of observations...
I actually have mine in one of those Silicon Covers - the new style 'Gel' ones (work really well and looks good too, unlike old Silicon ones). So it's not actually about having contact with metal as such.
Problem does not occure when plugged into USB.
Now this bit could just be perception rather than reality, but I tried typing while flat (USB disconnected) when touching the coated surface around the trackball and it did not seem to improve things. Trying to do the same while touching the metal area around the speaker grill did seem to improve things. You guys observing similar ?
Anyway, I'm hoping that when I have my car charger, it will fix my CoPilot problem since this should be the same as having the USB plugged in.

Ok, probably not. There's gotta be a perfectly valid explanation, but I just noticed this:
When I open Albums on my Hero and look at a single photograph, I can zoom in and out by pinching. Same goes for web pages. We all know this.
But the thing is: if I put my phone down on the table and try to pinch with just one hand (thumb+index finger), it doesn't work!
I only need to touch the phone with one finger on my left hand and it starts working. I have to touch the back or the frame. The chin doesn't react.
I tried it on an iPhone and it works with only one hand. It must be some conductivity issue and the Hero simply has a touch screen that works differently from iPhones.
It isn't really a problem for me: I can hold the phone in both hands while pinching. I just found it slightly interesting...
Yeah I have noticed that as well. Although if you try to calibrate using the g-sensor calibration tool it sometime fixes the issue...
Clue is in the technology? Capacitative touch screen....hit the physics books guys
A good capacitive screen doesn't require the user to complete a circuit with the phone using another hand to hold it, or by touching the bezel with a finger. The problem is either in the circuitry driving the touchscreen or possibly with the algorithms used to establish finger gestures and position.
It's even feasible that the metal bezel interferes with the electrostatic field introduced when your finger is in proximity with the screen. This would explain why the sensitivity is reduced around the edges of the screen.
Spose you need to form a complete circuit for it to work. Interesting point though, I didn't know that capacitive screens needed a second 'plate' to work (i.e. more than just the screen alone).
Makes sense though if you think about it.
Q.I indeed

The metal bezel actually acts like a ground point between the capacitive circuitry and your finger. When you are touching at the very edges of the capacitive area there simply isn't enough room to get a good grounding point so the driver/controller gets a hard time of locating what points are actually grounded. The bezel helps in this regard.

...perhaps not then lol
Yeah, well I hate to be the one to ask, but why does it work on the iPhone then? I realize it's a grounding / closed circuit issue, but if another similar phone can do it, then there's obviously a way around it.
And another question: Why doesn't pinching work, but normal one-fingered touching does?
Only place where I could see this becoming a problem is when you dock your device to some plastic holder in a car and want to pinch to zoom in some navigator software. Letting go of the steering wheel to use two hands on your phone isn't necessarily the safest thing in the world. One would assume though, that the interface in any navigator software wouldn't require complex gestures while operating it...

I am having issues with my touch screen not taking my input when in landscape. It works when I change to portrait and usually works when switching back to landscape but then stops again. I've noticed this playing angry birds and browsing in IE. Anything I can do to correct this?
edit: I think I found my issue. If i'm touching the bottom area where the capacitive buttons are the screen won't respond. Is this normal?
I find the sensitivity of the screen is less than the Focus. The Focus suffered from bad touch sensitivity if you didn't hold it (like laying it on the bed). If they can get full registry access to the phone, I'll bet the sensitivity is adjustable.

others have mentioned that touching the soft keys even slightly makes the rest of the screen unresponsive.
I don't know why capacitive buttons are so popular... they might be 'cool' but... hardbuttons aren't accidentally activated, they don't mess up the screen and they provide REAL tactile feedback.
Plus you can search for and use hardbuttons when they are out of sight. With my TV and BD player I have to put my face to the buttons with a magnifying class to see the icons because feeling them activates them and they have no backlights :/

They're popular because presumably they cost less than actual buttons, easier to manufacture, and are less likely to break or need maintainence.
The screen's glass is already set up to be capacitive, so extending that down to the "button" area requires virtually no additional cost - they only need 3 tiny LED's underneath, rather than housing full mechanical buttons, with a separate plastic overlays ontop on the buttons.
The SPen works great on the screen, but can't be used to activate the four capacitive 'buttons' at the bottom.....not sure why.

Because the part of the screen that contains the "digitizer" that the S-Pen uses doesn't cover the entire front face of the phone....it only covers the screen area.
Remember that the international version doesn't have the touch sensitive 4-buttons across the bottom...only a single mechanical button.
I assume the same screen digitizer was used for both devices.

There are certain movements you can do with the S-pen on the screen while holding the button on the S-pen that wil for example bring you back (in the browser(, show the menu, bring you to your homescreen!
When you're using the S Pen on the screen, it isn't actually using the capacitive capabilities to register the input, it's using the screen digitizer. The pen isn't capable of registering capacitive input.
With the Flyer's stylus you could actually use the other end of the pen as a capacitive stylus, although I'm pretty sure that's just a result of it being solid metal.

The international version has a mechanical button (home) and two capacitive buttons (back and menu).
But as everyone said, the S-Pen isn't a capacitive stylus like you might buy to use for a tablet; the note has a proper digitizer, which allows things like pressure sensitivity. It's nowhere near as good as the sensitivity you get with a Wacom input device, but it's a helluva lot better than a normal capacitive stylus.
Find the manual for the s-pen on the market. There are many gestures that allow yô to open menu's and navigate.
Like the title says... Is this a defect or a galaxy note feature?
Sometimes when I'm using the s pen, it seems like it taps the screen even though the pen does not even touch the screen yet. I can recreate the problem especially on the bottom right areas.
What I want to know if this actually a note feature.
It's weird because in those areas I only need to hover the pen and it will click/tap the icons there.

Same here... Bottom right just over the back button ... Driving me nuts
Happens to me too....
It is a feauture if you feel comfy with it. It is a defect if you do not feel comfy with it. I dnt find it to be a defect

There's been several mentions of this defect here on the forums already.
Here's the short explanation: the magnet from the speaker on the back of the phone is screwing with the s-pen signal a little bit in the lower right area of the screen.
Here's the short fix: wrap a tiny piece of aluminum tape around the s-pen, right at the bottom of the button, as seen in this video.
Or you can wait and see if Samsung makes an updated version of the s-pen that doesn't get the interference.
