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).

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.
Regards,
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?
Click to expand...

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 a bit of an issue with my new prime, and I thought I'd just see if anyone else is having the same issue. Wouldn't want to bother returning it if the replacement device is just going to do the same thing after all. Anyway, here's my description of the issue.
When I press down on the touchscreen towards the center, discolouration occurs. It's most noticeable on very dark, white, or single colour backgrounds. It's kind of like what you might expect would happen with an ordinary laptop touchscreen when you press down on it, except of course this is a screen that is supposed to be designed to be pressed. I ordered it from ebuyer, and I'm concerned that if I return the device, it could be a very long time till they send out a replacement, and I need it for work.
This is not a resistive touchscreen. Rather, it's capacitive. You are not supposed to be pressing it. It functions off of touch, not pressure.

You shouldn't be pressing on it hard enough to see screen distortion. The screen is fairly sensitive and doesn't require pressure; simply having your finger contact the glass should suffice.
IPS shouldn't do that under pressure. TN, *VA does. Well, of course, maybe newer IPS panels are not designed the same.
It's not something I've noticed using other phones and tablets, and I don't believe I'm putting undue pressure on the screen. You all seem to be suggesting that this is normal, but doe it happen on your devices? I'm sending it back anyway, no point in getting anything other than a perfect copy when you've spent thi much.
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!

Sent from my GT-I9300 using xda premium
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?
+1
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)

Sent from my buttery smooth S3
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.
So I'm watching youtube on the dual screen using landscape and I want to sleep the main screen so i touch sleep main screen option on the dual screen tab tool, it shows a prompt saying main screen will dim to save battery and swipe to dismiss. I dont touch or swipe anything and the prompt swipes itself away and screen undims or sometimes doesn't even dim. This is also the case with Call of duty mobile, when I'm playing the game in battle royal mode the mini map enlarges randomly even if I don't touch it, and the voice chat options will engage and open without me touching those as well. Anyone else has this problem? Any solutions?
I could have sworn I saw a post earlier about ghost touches, though I can't seem to find the thread it was in at the moment.
I've been using the phone heavily since I got it on April 1st, and I have not experienced this issue at all.
Any chance you had an LG phone prior to this and used LG Switch to transfer over all of your stuff?
I've read reports here that doing so can cause some pretty serious battery drain and/or lag issues, so there could be other bugs as another side-effect.
Have you tried a factory reset?

If you play a YT video on the second screen and lock/sleep your phone, the second screen goes to sleep as well.
I didn't bother with headphones for this test, and noticed that the audio comes out of the phone's speakers.
It appears that the second screen doesn't have speakers of its own.
So yeah, you cannot watch something on the second screen while having the phone asleep.
And it make sense. It's just a screen. No second pair of speakers. No second headphone jack. No separate battery. No second set of modems, etc.

Actually you CAN watch youtube on the second screen and sleep/dim the main screen by using the floating dual screen button. It has an option asking if you want to sleep dim the main screen to conserve battery life. It does work for me now, I'm not sure why it was going wonky on me when I first posted but hopefully that it doesn't do it anymore. I'm guessing the tmobile April security update did the trick. It's just I have phantom touches on call of duty still.

This is happening to me as well when I'm playing PubG Mobile. The ghost touches are happening not on the map but to the left of that. On another LG V60, the device would get random dead zones as well.
I'm going to do the following test and suggest you do the same and report back your results.
1. wait until the ghost touches start happening and flip the phone around. hopefully the ghost touch continues to happen in the same exact location of the physical screen, and it triggers a different button
2. remove the screen protector and try the tests again
are you using a screen protector?
might process a warranty replacement if the results are reproduceable

Oh, that is good to know. I'm not using the dual-screen attachment anymore (typing in portrait mode is IMPOSSIBLE with it), but I only ever used the Dual-Screen notification shade tile to enable the second screen, not the pill button thing. I should have explored our options more thoroughly. Thank you for correcting me.
Edit - I have recently added a tempered glass screen protector to my phone, and while it completely screwed with my fingerprint biometrics (I had to delete the fingerprints and redo them), the protector itself is not causing any ghost touches for me. And once I redid the fingerprints, there have been no further issues there either.

Yes I am using a screen protector and I was actually thinking that might be the problem, although it seems like a solid install. I just got the update for cod season 6 and I'm downloading now. I'll see if that solves the problem. I'll also try what you suggested and then post results
Update: so the cod update did not fix the issue, but I tried doing as you suggested and flipped the phone around and the problem went away. I then tried flipping it back to original and problem persisted. I think it is the tempered glass. I don't want to remove it since it cost me 40 bucks. Any suggestions?

So I installed the update for cod and it still had the ghost touch problem with the top right side of the screen, iflipped the phone per what jd254 suggested and I didn't get the phantom touches. I'm assuming it is the tempered glass that is causing it. I dont want to remove it cause it cost me 40 bucks.
2nd update: so I tried taking it out of the dual screen case and notice it doesn't have phantom touch ( I played a full game of battle royale) so I'm not sure if its the tempered glass or the case. Need to investigate more

Is the case touching the tempered glass anywhere around the the edges? If the case is pressing on the screen protector and lifting or peessing it even the smallest amount that could cause phantom touches maybe..just an idea
FWIW, I'm using both a tempered glass screen protector and a case that wraps around to grip the front of the phone a bit, and I'm not getting any phantom touches at all.
The case is NOT rubbing up against the edges of the screen protector, however. Which is fine, because if it were, it could potentially dislodge it.
Or, I suppose, cause phantom touches.

Ok more investigating and playing codm I notice that the mini map opens up when i perform a touch combination with my thumbs. So the map gets triggered when I press and hold up on the left side virtual joystick to sprint and press the jump virtual button on the right simultaneously. I can't recreate what button presses open the voice chat box, but now I have to strike the dual case as being the problem along with the tempered glass, at least i assume those aren't causing the ghost touches.
For anyone having touch issues, as a troubleshooting aid: enable developer options, and then toggle on "Show touches" and "Show touch data". Might help figure out what is going on.

I'm getting VERY interesting results.
1. dead spots: I moved my finger up the right side of the screen to look up. my character did not look up, which I would assume there was a dead spot before. This is incorrect. I can see the screen registered using that option mentioned above. the screen registered the action, but didn't pass it to the software?
2. FPS drops: I assume it's an FPS drop because everything was laggy when this happened. (PubG mobile was set to max settings, and runs 100% fine, until now) I was flying the helicopter, so I had several fingers on the screen at the same time, with a lot of rotational movements. the screen doesn't clear all of these movement data until I literally take all my fingers off the screen for half a sec. When I did that, it stop lagging.
3. ghost touches: Each touch on the screen has an x and y axis point to tell the software where it's being touched. With several finger on the screen (sometimes 2, but commonly with three or more), I noticed that the y axis for my left thumb and the x axis for my right thumb was creating those ghost touches! The screen would combine the x and y axis from different fingers to create a touchpoint on the screen.
so I don't care too much about 1 and 2, but... what can I do about 3?

Yeah I noticed a combination of touches triggers the ghost touch on call of duty, I could also be having the combinations trigger ghost touches in other game but I need to test more
