I just got my Archos 28 a day ago.. and while I was playing with it the screen randomly starts to get jumpy while using my finger. When I use a stylus it works perfectly, but I'd rather not carry around a NDS stylus everywhere I go. I've calibrated many times using both my fingers and the stylus, but it's still nearly impossible to type on the keyboard or drag icons around the main screens.
Are there any alternate calibration programs? Could this be a hardware issue?
Have you used the one under setting>reformating>touch calibration..... try that one and reboot..

About 15 times... Haha.
It's weird because it's like it detects the full surface of my fingertip so it thinks I'm dragging it or something.
The 28 uses a resistive screen, which will not respond as well to a finger tip as the higher end conductive screens. The resistive type screens also require a bit more pressure than capacitive screens. Having used resistive screens for years prior to todays capacitive ones, I've always found using your fingernail instead of finger tip seems to works best if you are not going to use a stylus.
My finger works nicely on my sister's Archos 28, and we got them at the same time. It's actually a really nice resistive screen, some people thought it was capacitive until they used a nail or tried multi-touch. I don't think it being resistive is the problem though, seeing as I can use my sister's perfectly fine...
I want to try calibrating it using a different calibration app than what is already included in the Archos. I saw a thread somewhere on the internet about another application that worked for someone, but that was before my problem happened. Now I can't find it.. Haha.

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.

Dave
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 have seen multiple mentions about Prime's touch screen requiring 'stronger touches' to react. Is that true?
I would like to use the tablet for sketching, which is done with capacitive pens (like the one made for iPad 2 by Bamboo) which have a sort of an 'air pad' on the tip, making every brush quite light. Does anyone have such a pen and has tried it on a Prime?
It will be frustrating if I cannot use the pen at all if Prime does not react to the less-prominent touches. I also prefer light touches for actions such as swiping across the screen in galleries or on Google Maps instead of making the swipe very prominent.
If you have Prime, could you share your touch-screen experiences with it?
Or is there a video that demo's Prime touch screen with a multitouch app with varying touch stroke strengths? If you have the Prime, could you record such a video? I am sure many would appreciate it
I dont have a pen but it seems that sometimes it takes a harder touch to select anything on the home screen but for.example when im using the browser a very light touch will scroll just fine

yeah i'm interested in that point to. I have the Bamboo stylus but not the prime.
Asus stated that the touch screen was more responsive (faster) than the average Android tablet and I 'd love to see how that goes compare to say...the original Transformer !
I get my tab tomorrow I have like 3 different stylus I can test out.

Do any of them have an air-pad type of build? Bamboo stylus looks like an 'eraser' from one end, but it is actually an air-pad of sorts, so it is very light. I know that many capacitive pens are like less-friction erasers, completely filled. These are easier to make taps with on less-responsive screens. But they are not as smooth and light for writing naturally.
I am especially interested in the air-pad type of capacitive pens like the Bamboo is, since they are better for sketching and natural handwriting. I wonder if such pens have issues with Prime (they work perfectly on iPad 2 which reacts very well to light brushes).
The cosmonaut and the rocket fish are both air pad type

Great! Do let us know how they perform, it will play a huge role in my decision whether to buy the device or not.
I hope it works well with my Jot Pro stylus, too. It's really nice on a borrowed iPad 2.
my jot pro is coming today so i can report back then.
but as another poster said, some times selecting items seems to take a harder press than my xoom did but scroll in the opera browser is almost too senstive.. the slightest touch scrolls the browser..
i think you will be fine with your pen.
My touch screen is very responsive I feel no need for a stylus but it wouldn't hurt
I don't have a pen device, but can give a point of comparison...
The touch screen on the Prime is much less sensitive than the one on my Xoom. I wouldn't call it bad, but I definitely have to press harder to register inputs.
Jason
my touchscreen seems very responsive. seeing this thread made me back out n test it again. on my prime, the slightest touch barely touching screen will have it scrolling up, down, left, or right very smoothly. I mean literally the slightest touch and the prime will react. I have a capacitve pen also that I used sometimes on my Ipad for drawing apps like Sketchbook n such. I can't remember the brand of pen. I think its the Targas one. I bought it at best buy when they had their sale on them for cheap. the end of pen is more like half a spongy rubber ball of sorts. if you press it too hard against screen it'll mash down end of tip. so end of my pen tip is not solid. more like hollow rubber end that flexes with pressure. I haven't tried it out on my prime yet. I will though after seeing this thread.
That's weird..Do someone have the original transformer and could give us a comparaison between it and the prime, maybe in a touch screen test apps (wich should not be limited in speed by the software optimisation)
I was looking forward to what Asus called a faster responding touch screen but it seems like they forgot about this one. Or maybe the xoom was very fast. Or it's a software thing or it needs more indepth test to tell
The thing is, I don't NEED a stylus but I'm using one to draw in sketchbook and it's already not always perfect on the Transformer (still good though) but I wouldn't want it to be even less sensitive. It's hard to draw correctly when you have to press the screen like a mad men.
When I first got my prime, I had issues with the touch screen. Typing was especially a pain because it wasn't recognizing key presses. I then used the cleaning cloth that it came with and cleaned the screen really well. Since then I've had no problems.
I'm guessing that the protective plastic left a film.

The firmware updates helped alot too
The cosmonaut words terribly with the prime.
The rockfish works pretty good when writing, but for delicate touches when drawing it its a bit jittery. Looks like I'm making dotted line instead of solid lines. Needs a fair amount of pressure, but not super hard.
However when using fingers to draw even light touches work great.
Waiting on funds to get a adonit jot pro bc I hear that is the best stylus

So I bought the C-Pen but for me it's horrible. The lines aren't nearly as accurate when done with my finger and sometimes it doesn't register at all. Anyone else having this?

Returned mine the same day I received it. A cheap pen from ebay, worked much better and without missed clicks. Wasn't expecting this really. In addition, the c-pen didn't work on the capasitive buttons. The cheap one did.

Was it like really inaccurate for you too? If I drew a pretty straight the line, it would almost always come out all wobbly. Then when I drew with my finger the line would be all smooth. And on some points on the screen I couldn't even draw at all sometimes.
I am without a doubt going to send it back. Really ****ty product

The problem is that capacitive screens only have spots they react on, not every single location. So the pen has to have a large enough tip to cover at least one such spot under all conditions; something which is always given when using your finger.
(In fact your finger usually covers multiple spots)
These spots don't really allow for smooth transition in e.g. diagonals.
The cheap pens off eBay have a larger tip which covers multiple spots (like your finger) and work thus better.
On older screens or elder tablets (e.g. the Wetab) they are still unusable and will result in the same issues you're having with the c-Pen since those screens have even larger gaps between the spots.

Yeah, that makes sense. Actually I could draw a straight line with it just fine but at the upper part of the screen it became unresponsive and really annoying to use.
Can't comprehend how such a product could be advertised as "exclusively optimised for S3".
Oh no.. I placed order few days ago!
I've been researching this C-Pen to decide if I wanted one. What I read on Amazon.com is that it seems to work ONLY on an S lll. Does not work on other tablets or phones. Now, I wanted to be able to use a pen on a tablet I have so I figured this was a negative for this particular pen.
If it doesn't even work well on the S lll what is the problem? (rhetorical question). My main interest in using a pen was not as a substitute for my finger but to actually use the S Memo for sketches.
it seems to me this technology is not yet sophisticated enough for prime time.

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
《tapatalked from galaxy s3》
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.
