Edges of screen unresponsive (Unless touching bezel!)

This is my first phone with a capacitive screen, so perhaps it is a quirk of them, but I have noticed that if I am not holding the phone in such a way that I am touching the metal bezel, the screen does not recognise touches that are close to the edges of the screen. It seems that the screen requires a circuit to be made with other metal parts on the phone before recognising the touch.
For example, if I put the phone on my desk and touch the backspace key with a single finger, nothing happens. If I keep holding my finger on it, and touch the metal bezel, hey presto, the button clicks.
This reminds me of a watch a friend of mine had a long time ago, that had a capacitive "hair trigger" button that only worked for him (because it required a circuit to be made with the back face of the watch, meaning when he pressed the button it completed a circuit through his body)
Anyone else noticed this? It is slightly annoying because I have to hold the bezel when I want to use the phone..

Confirmed.
And you might very well be correct in the assumption about the circuit not closing in every part of the screen. I think it's the nature of any capacitive surface tbh. If you press in the middle of the screen then there is enough adjecent space to actually complete the circuit while on the edges there is simply not enough space around your fingertip to not close the circuit at all. That is why touching the bezel works.
But as I have been holding my little Hero in my hand while typing anything I simply didn't know this little odd thing. I have read about it though.
Yet another reason to hold your precious little Hero in your hand...

Wierd not like that on my samsung.. its all plastic tho

Mine is the same.. especially on the right hand side of the screen. If it's in a case it makes it really bad!!

Sounds like bad shileding and grounding to me

Didn't notice this until I put a screen protector on but now it's really bugging me.

On a related note (metal bezel related), I've noticed that in dim lighting the button backlight flickers. But if i touch the screen and bezel, it stops.

Same here. Could it be that the screen protector slightly touches the aluminium casing and thus grounding the screen (or creating a wrong potential)?
I noticed that when i touch (=ground) the outer aluminum frame with just one single finger then the touch screen works flawlessly.
(I'm using the offical HTC screen protector).

Hmm definatly bad grounding issue. Its either some pretty poor design or a defect.

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!

Odd Screen Dead Spot

I've been having a weird screen issue lately, independent of rom or kernel; my screen won't respond to touch input directly beneath the status bar.
For instance, if I touch an icon or button at the top of the screen, it does not respond at all... Unless I rotate the phone into landscape mode and select the command.
The status bar itself works fine, I just have to tilt the phone to use the area of the screen underneath it. Weird.

Just a shot in the dark, do you have a screen cover that might have lifted a bit?

I have a matte, anti-glare cover, but it's tight as a drum. Not even an air bubble.

Similar thing happened to my last phone. Only it was the bottom corner. Never found a solution. Ended up getting new phone.

bug of the stylus to s memo

do anyone of you notice this bug...
1) when the phone is placed on table flat(with screen facing up), there is nothing wrong...
2) when the phone is place upside down (with screen facing down, when you have the phone on bed and over your head), then without having the stylus pen actual touches the screen, the screen senses it and leave a mark.
it even can activate any icon...
is this me only or general bug?

It effects all Notes. Its a known issue with this digitizer.
Basically touch is registered without pen actually touching the screen when you are using it laying on bed where screen is facing down. It registers from about 3-4 millimetres away.

I'm trying this right now as I post this and I can't seem to replicate the issue...

I'm having this same issue..didn't realize that it only happens when it's faced down..well,hope there'll be a fix soon.

Little one handed trick

Hey Everyone,
I do this every now and then, wondering if everyone else does.
Let's say I'm using the phone one handed, web browsing or something and I need to reach a button on the opposite bottom corner.
Rather than stretch across the screen, I just rotate the phone 90 degrees for a second. The screen rotates, and the button is now directly under my thumb. I click it, rotate back and move on.
Yes, the Note still sucks sometimes as a one handed phone, but this does help out every now and then.

oh thanks nice idea

another way is to curl your finger around the back of the phone...I did try this, and looks really funny if you're watching from afar

I guess I just have big hands. The way I hold the phone, I can touch everything to the right of the blue line.

Ha.. same here. I've got big hands too. One overseas colleague once asked me if that is a S2 I'm holding.
If I'm holding the phone, you can only see 1/4 of it from the back. And only 1 cm separates my thumb to the closest finger when I hold it.

This is particularly useful if you're reading in landscape.

another trick for zooming during browsing with the stock samsung browser is to simulate 2 fingers. usually you can zoom in and out by putting them on the screen and overturn the phone.
so instead of using to fingers, just put your thumb on the left side of the screen, so that a small part of your palm touches the screen on the right, which simulates an input^^
i hope u understood what i mean

I never hold my phone 1 handed. I'm too afraid of dropping it. But I'll try your advice if I ever need to

[Q] Phantom touches screen issue

So I've been getting ghost or phantom touches on my phone for the past few weeks. I couldn't figure out what was causing it because I've never dropped my phone and it never got wet. The phantom touches only appears down the right side of the screen in almost a straight line. It doesn't happen all the time and I thought it was random but I got it to occur at a successful rate. If I press down on the top left corner of the screen, it would cause the phantom touches. When I press and hold down the top left corner of the phone, everything is fine and no phantom touches appear. I decided to tighten the screws on the top left and it seems to have made it a little better. I'd have to really tap on the top left of the screen to make the phantom touches appear again and it doesn't occur at a 100% rate but it's still occurs.
Anyone know what is causing this? I thought it would be a broken digitizer but it doesn't make sense that tightening the screws would cause the issue to almost fix itself. Problem with the geomangnet? I'm not sure what that does really.

Put 2 (or more) fingers on the screen of your Note 3 in a horizontal line in landscape mode. You can also use Portrait mode with 2 fingers.
Move the fingers slightly about, trying to have both (all) in a straight horizontal line.
After only a bit of trying one (or more) detected fingers should disappear (become undetected) or ghost touch detections should appear.

Thank you for the help and suggestion but I've already tried this. My touch screen is fine in terms of detection. I can put 10 fingers on the screen and it would recognize all 10 fingers. My issue has something to do with the top left corner of the screen affecting the right side of the screen. Like something is loose. When I clamp down on the left corner of the phone, everything works fine. No ghost touches (that sounds dirty) or any of the sort. When I let go of the top left corner, I will some times get ghost touches.

It's not a firmware issue. It's definitely a hardware issue since it starts tapping on buttons inside TWRP recovery. Ah well, I tighten the screws even more and it looks like the phantom touches are gone. Hopefully it stays that way even though I destroyed a screw in the process. Those tiny things are fragile.

if the touch ghost click is in some certain location most because of pollution (mainly chemical), best is use ISO alcohol also use a very tinny sharp blade, like a very thin one and slightly go along side the place that does this, sometimes you have to try both horizontal and vertical, then clean with ISO, do a few times it does alright. it does work on most of touch screen include note 3 as well.
