Have any of you experienced something like the screen registering a touch even if you didn't really touch it (or it didn't feel like it did) while having the finger very close to the screen?
Its something that happened me very randomly and not so frequently with my iPod Touch, but now with the S3 is something definetively more frequent, and sometimes is annoying, very weird!

Is there any particular reason on why it happens, or anything that could be done to 'fix it'
Its just a little nuissance,for example after typing a letter in the keyboard, in just one press it will register 2 or even 3 touches, one before really touching, when touching, and one after touching (being 3 times very rare and 2 touches a bit less than uncommon)
Weird, though the s3 screen is super sensitive I haven't experienced any double touch so far. Try testing your screen using multi touch tester and see if you can trace anything weird there

Just wondering......can it be affected by static electricity?

I've had this a few times, but not so much that it's annoying. I'm using a generic e-bay screen protector. Anybody else who is having this phenomenon got a screen protector on, or are you going nekkid ?
I've had it too but very rarely. Don't think it's much of a problem. Capacitive touchscreens work based on the electrical charge our skin possesses so your static charge theory might be right(correct me if I'm wrong)

I'm guessing wearing wool or nylon clothing here might be part of the problem! Also atmospherics can play a big part. I seriously don't think this is a hardware problem at all imho.
Yep i get this too, can espically see it on the 'test' screen where you are drawing on it, sometimes my finger passes right over it and it registers it. I'm going with static electricit and the screen protector generating a little current just before your finger touches as the culprit.

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.

Am I the only one having really poor touch recognition on my A43? Whether I use a finger or stylus, it often happens--about once in five keystrokes or more--that after releasing the touch on an on-screen keyboard, a different key additionally gets registered, sometimes not even a neighboring key. It is very hard to type in a password.
My touchscreen also has this problem. I'll hit one key and it will add another key somewhere entirely else on the screen. Menus will spaz out when I try and scroll through them.
Oh yeah, remember that problem I was having where strange spots showed up on the screen and I had to get it RMA'd? That came back on my BRAND NEW unit. I'm getting sick of the crappy screen on this otherwise great unit =[ Maybe Archos will just give me a refund and I can spend my funds on an unlocked/off contract phone with similar specs.
Sadly, I think this is a hardware issue. I'm not sure there's anything firmware can do besides ignore half of the inputs. But then, you have a non-responsive issue ...
Have you guys tried to calibrate the screen through SDE?
I have a similar issue with my A101, although it's not as bad as you guys describe - sometimes the screen just won't register my touch at all, mostly in the edges of the screen - sometimes I think it's the calluses on my fingers from playing guitar, sometimes I think it's the horrible screen they gave us....

So does anyone not have this problem with an A43?

You might be having better luck because the A101 has a capacitive screen with multi-touch capabilities. They're known to be more reliable than the resistive screens the 43IT's have.

I have a 43IT, which is why I posted Sorry I wasn't clear. I feel your pain. Also, I suggest using your nail or a stylus, as the pinpoint hardness of either are better than the soft, blob your fingertip makes on the screen sensor array.

I generally use a stylus. The problem is probably due to the way the plastic digitizer flexes which generates ghost movement data on release. A glass digitizer would be much better.
By the way, it is possible to ameliorate the problem slightly in software. I did that in the myKbd app for PalmOS. Basically, you filter out some very rapid motions. It doesn't affect sensitivity in any significant way.
The reason I'd like to know if everyone has this problem is because I'm going to send my A43 in for warranty repairs, and I am wondering if I should include this problem (in addition to the annoying bright 1/4" area on the screen, and the occasional timeouts when writing to internal flash that result in the device hanging).
I S-OFF`ed my EVO 3D, flashed a custom recovery and a custom ROM (LeeDrOiD's latest), so I'm not on stock (if that's what's causing this).
Back in January, when it was cold outside (5-10 degrees), at times, after extensively using the phone outdoors (like 15-30 minutes), once I went into a warmer place (warmer by a few degrees Celsius, like 5 or so), the touchscreen was completely unresponsive. I could only lock or unlock the phone, but was unable to do anything else (which means using the touchscreen or capacitive keys, for that matter). I figured it may be because the screen was very cold or something...
I had to wait ~30 minutes for it to recover!
I figured that has something to do with the screen being somewhat covered by a very thin layer of water/ice or something... which rendered it almost completely useless (I was still able to drag the lock ring up a milimeter one time, out of ~20 attempts ).
----------------------------------------------------------
Now, it's almost April. It's warm here, alright, which means no more moisture outside (regarding the temperature, at least).
But there was drizzle outside yesterday, and I had to text someone. Several tiny water drops landed on my phone's touchscreen (not too much, covering like 1 centimeter in lenght), and the phone began to register mistaken touches...
The same happens when I try to use my phone with my fingers BARELY wet. I have to wipe the screen ENTIRELY to make sure it's not registering 10105909 touches all by itself...
This is ridiculous. Not even the HTC Desire (which had only 2 multi touch points, and even those, not so accurate) didn't have this problem! Nor the Desire HD.
Am I the only one?! Are you experiencing this, too?!

As far as I know there is a small current running on top of the screen. Any kind of moisture will make your screen go crazy. Thats why I use a screen protector, because my sweaty hand dont play nice with any touch screen phone like the Evo 3D

As a matter of fact, I do use a screen protector. I've used MOMAX Anti-glare, MOMAX Clear, and right now I'm using a no-name crappy sheet that makes the screen look all wavy and shyte... I'm gonna apply a MOMAX Clear again soon.
Still, that's not the issue. Screen protector or not, the issue remains.
If you ever had such problems, please tell me what device are you using. CDMA, or GSM (for Europe - golden or for US/Asia, like me - red)?!
Same here, even when screen is completely dryed out.. What can we do about it?

I cleaned the screen with my blouse after I've been playing on it outside for 30 minutes. Cleaning did nothing...
Yesterday, it was raining. Not too big rain drops, but I let about 20 of them to cover the screen, some were little, a few were huge. The screen performed wonderful (in the time I tested it : scrolling across the menus, typing a fast message, probably less than 20 seconds).
What the hell...
---------------------------
NO responses?! Come on, I can't be the ONLY guy this is happening to !
There are 2 common types of touch screens. Resistive, which respond to flexing a thin sheet of plastic, and capacitive, which responds to an electric current. Resistive is not accurate so no one really uses it anymore except on knock off Chinese tablets. We have capacitive touch screens, same as apple products and every other popular android phone.
Any kind of moisture will interfere with the touch screen. Even if the air is very humid. There isn't much you can do if you are having those issues. And all electronics have specific temperature ranges they will function in. I don't know what the evo is rated for, but I'm sure it's somewhere.
Best advice is to keep dry. And no, a screen protector won't do much to help.

I know... I just thought the 3VO might be faulty, since, as I said, the Desire and the Desire HD never had this problem only with a few water drops...

The touchscreen on my Verizon G3 started acting up recently. In the lower portion of the screen there's a space where it doesn't register my touches well (take a look at pics the space in between the lines don't really 'register' my touches. You can see in the second pic I'm currently touching the part where its not really working and it looks like I'm touching the screen with two fingers even though I'm only using one). When I type sometimes two letters are pressed at the same time or its like I didn't touch the screen at all which makes typing difficult and takes a lot of time. The whole screen sometimes doesn't hold a touch, like I tap and hold but it only 'holds' like I only tapped the screen. Other times when I'm sliding my finger across the screen, it starts jumping around. Now the top row of the keyboard/screen doesn't even register touches anymore so can't really do much now. I've reset the phone and didn't fix anything. Is this something LG would fix if I sent the phone in? If so how long is turnaround and will I have to reset it back to stock/unroot it?
if you have any type of glass screen protector on, take it off and verify the issue.
some tg screen protectors are junk, and have caused issues like this.

I had a $5 glass screen protector on it from ebay and thought that was the problem but when I took it off the problems ensued
Some g3s do have or develop touchscreen issues. Check under the back cover that there is nothing putting pressure on the display from behind, like a swelling battery.
It is probably a warranty issue, though.

Hi guys. I have an old I9300 and it works great for it's age. But, when it gets a little hot it stops responding to my touches. I found out that the only solution is to press it hard in the lower left corner and then it works normal after that until it happens again. This solution works all the time. I tried opening the phone up and pressing that part (there's a connector for something there) with a small piece of paper, but it doesn't help.
Anyone had any problem like this or something?
Thanks
PS: is there any remedy for the horrible screen burn in except a new display?
Lick your finger and touch the screen. if it doesn't work then the digitiser may be delaminated or faulty.

This sounds interesting enough Will try the next time it happens. Will also feel stupid doing it, but yolo.
Conductive screens work on moisture on your skin causing an x-y voltage drop..
Capacitive screens work on x-y voltage resistance caused by pressure..
If it's glass is conductive. If it's plastic is capacitive.
Wetting your finger makes sure you don't have dry or dirty hands and ensures a good contact. If you were licking the screen itself you might get a funny look from passers by..
