Iconia Tab Capacitive Touchscreen Defect - Acer Iconia A500

I just bought this yesterday and could not figure out why I got double keypresses in the virtual keyboard whenever I pressed the i, o, or 9 keys. Turns out after some testing that I have a defect in the capacitive touchscreen. Video here: youtube.com/watch?v=WWPqzqNrS28 (I havent posted much so I cannot use the full outside link) I will be exchanging it tomorrow, I am hoping that I dont get another lemon, I was really enjoying this device...

Just sent off a "faulty" Touch HD.

Hi,
I think I may have made a mistake, but was wondering if anyone else has / has not had a similar experience.
I got my Touch HD a couple of weeks ago, and although I was completely knocked out with its amazingness ( new word, patented by me! ), something bothered me about the amount of pressure I was having to use, particularly in the centre of the screen when touching.
I know there have been tweaks and hacks posted and the pressure required on the touchscreen is variable, so I fiddled and tweaked and carried on. It was only after I started using FingerKeyboard2 (which also warrants "amazingness" status.) that I noticed that when holding keys down and releasing for special characters and numbers, my HD was registering a second press upon release. So when holding for number "5" I got a letter "t" too when I released. This really annoyed me.
I've had a look from a varry shallow angle at the screen, with the device turned off and pressed in the middle and compared to the edges, and it seems as though the digitizer "domes" over the screen. There's a large void in the middle that's not present at the edges, which means that to register touches in the middle, I have to press the digitizer against the screen. I think this is causing the double presses, and having to apply extra pressure in the middle.
Anyway, to cut a long story short, I've taken it to CPW today and they've sent off for a replacement, which will arrive on Monday
Has anyone else noticed this, is it normal and I've sent a perfectly good Touch HD away? Have a look for me please, and spare an old(ish) man his sanity!
I can only speak for myself but, specially after tweaking, the hd screen is VERY sensible to touch, no need for hard presses at all. I think you actually had a faulty machine...
My touch screen is very good, shame the wifi has died on it and it's doing strange things. Mine will be back to CPW as well
My touchscreen works very well, without tweaking I think it does the job and recognizes my presses easily and accurately. However, my problem is that I can see the touch sensors even when the screen is turned on... I see small green-coloured dots, in a regular grid, specially when I have a white background. Annoying, but I think I can live with it... Better than send it to the service and wait a long time, with the risk of getting a new screen which may have dead pixels (I don't have any now).
Thanks for your replies everyone, makes me feel better about not having my Touch HD over the weekend. I pick up my replacement tomorrow and I think I'm suffering from withdrawal already.

I have it now,but not happy at all

1.first i had problem to hard reset it,it is not done as users manual says.
2.Digital Compass app needs to Rereset after each soft reset.getting "Magnetic interference" Error
3.Screen is so sensitive that is almost impossible for me to write text messages or e mails.came off Touch Pro 2.there i had no problems.
4.my Volume UP button sudenly stoped working
i think,they rushed the release and made this device pain in the ass.maybe we need a NEW ROM!!!
mine hasn't had these problems, knock wood. And I am loving the speed!
With the screen being so sensitive... why does that make it impossible to write text messages? it just means you dont have to bend your screen when pressing so hard to press a key...?
Having had a Touch HD - owning a TP2 (work) and just having sold an Iphone 3GS - I honestly love mine to bits.
Been playing with the phone all evening - and I have to say I am really impressed - Vibrant screen, awesome speed, gorgeous flash (vid's and pics are quite good too compared to my other/previous phones) - All in all I am well impressed. The OS sits together so well - not having to touch WinMo at all, that this is one ROM I might just stick with!!!
I like the hard buttons on the front of the device - one of the bad sides of the blackstone but I have to agree the screen is VERY sensitive. As I'll be getting an invisishield for it as soon as they are released - this will make it much more useable - struggling at the moment but I can honestly say its a good thing - VERY precise screen - compared to the iphone 3GS (which sometimes required a double press to register) - You just have to think about touching this phone and it reacts - lol
Overall - VERY PLEASED and super happy I ditched my iphone 3GS for this oh and its VERY slim - in fact one of the slimmest HTC devices I have ever laid my hands on. All in all about 2mm bigger in depth, width and height than a 3GS but with like 50% more display area - Now THIS is what I call an iphone killer.

And I just say you're out of luck. inoperative volume button... sounds like a defective unit, not software.
Replace it and be happy again.

heh, if your passing by hudds soon i.e. on teh weekend let me know fella and i'll hook up.
I agree on the sensitivity....it's awful....if, for example, you type something incorrectly...VERY easy to do..then press delete quickly a few times, it doesn't delete..it starts typing random characters!!
hoping there's a setting for this somewhere. A screen protector might be the answer though in the short term
I also had to hard reset (because I wanted to..not for any other reason) and I followed the procedure in the manual, has been the same for all HTC devices I've had
Not to *****, but the guys saying that the screen is too responsive... Are you used to capacitive screens? You need to get used to it for a bit, especially when you come from resistive screens.
Also, a phone that is TOO responsive? You never hear that from a WM phone .
compared to the iphone (yes, I know..I'm sorry) the screen is lousy!!

that's exactly what i ment.it is realy hard to wrife witbkut making a mistake.
So does it means that none of you guys hav this Digital Compass problem?after each soft reset i have to repeat that 8 shape pattern movement to make it work again.
anyway i am returning my to get a replacement.
I don't have an HD2, but I think I've experienced this over-sensitivity on my iPod nano, which I presume has a capacitive scroll wheel.
Sometimes (although not usually) it becomes so sensitive that I don't have to actually touch the scroll wheel for the songs to scroll. It then becomes almost impossible to choose the song I actually want because when I move my finger to the select button the song changes before I can select it - very, very annoying and frustrating. I'm not sure why it's sometimes much worse than at other times. Maybe it's the temperature of my finger or something.
Anyway, it sounds like this is the same sort of thing that's happening on the HD2. It's a real pain on my iPod, and I would find it totally unacceptable on a device like the HD2.
Its just a case of getting used to the screen. Our fingers are too used to resistive screens that we don't actually lift our fingers enough and drag across the screen since unless we apply enough pressure on resistive screen it won't do anything. With capacitive we just need to re-train our fingers to lift off the screen another 1mm and it'll be fine.
Here's my suggestions:
1) Try typing slower to start with.
2) Or turn phone to landscape as the keys on the onscreen keyboard are slightly wider.
I can type quite quickly in landscape with between 1-3 errors per an SMS.
I'm loving this phone right now!

You're 100% right!
I also was very frustrated and irritated the first two days. But then I realized how responsive the screen is. Just a very very light touch already gives a reaction. And now I'm loving it more and more by the minute...

Mine was delivered with a faulty 'Volume UP' button. I've sent it back for replacement.

Just try another keyboard. One that doesn't allow to change a character once you pressed a character on the keyboard. Fingertouch Pro and Resco Keyboard Pro for example are great keyboards for the sensitive screen of the HD2. I myself like the Resco keyboard. It responds and looks very similar to the iphone keyboard.
BTW Fingertouch pro and Resco Keyboard Pro both allows you to make use of gestures. Together with this feature text input is a breeze on the HD2
(Better yet is MessagEase, but unfortunately, under WinMob 6.5, it has some real problems).

Hey I am in wakefield too! Small world
I have to agree the screen is very sensitive. I am sure with a weeks usage I will be ok.
I have to say though I am so in love with the phone. The speed is perfect. No more waiting to load SMS\email screen etc like with my touch HD.
Hehe thats what happens with everyone who switch over from Resistive to Capacitive, at first they will hate it as they're too used to resistive.
But just within 2-3 days they realize just how much better Capative is. Resistive just sucks IMO. Typing is way quicker using a Capactive panel.

I had exactly the same experience switching to my G1 - I sent the first one back after a few hours as i was convinced the screen wasn't working. The next handset was was the same. A day or so of use later and I was sold and never looked back.
no..the screen is definitely too sensitive...this is not my first capacitive screen btw.
I've got my phone on charge on the desk next to me...and number of time it has open the calendar, or contacts...all by itself is amazing. A few moments ago (which has prompted me to write this post), it opened the calendar and the curser moved all over november....18, 19, 20, 24, etc etc...without me being anywhere near it!!
there has to be a way to turn the sensitivity down

screen sensiviity ruining experience

right now........I HATE this phone
the screen is so sensitive it's ruining it for me
even a bit of dust makes it impossible to type a text message. there must be a way to decrease screen sensitivity or it's going back. I'm so pissed off with it right now
Sorry. Think it quite funny.
People have been complaining how insensitive the resistive screen. Now there is a capacitive screen its the opposite.
I hope I don't eat my words in a few days when I get mine.
Quite a few people are complaining about the over sensitive screen then changing there minds after a few days.
How is the dust making it hard?
I love the screen, and tipping is super fast for me.
Best phone I ever have.
The screen is amazing.
Much easier to type than on resesitive screen. you just need to get used to it.
have you guys (found) any videos of typing on the hd2? Wonder what it looks like and if you can become as fluent as with a hw-keyboard?
I have same problem here. I was using Touch HD before and now I can't type anything without making mistakes. T9 helps out but when it comes to password it's getting painfull. When I'm pressing letter on on-screen keyboard I quite often press other keys around. I guess it will take quite some time to get used to it, I don't think sensitivity can be changed.
P.S.
Guys from pocketnow claims that HD2 has about the same sensitivity as Pro2 and definitely less then iPhone. If it so I can't imagine how people are able to use iPhone
we have all been used to resistive till now. you'll adapt dont worry, its a change that we all now have to go through.
i have the ipod touch so i dont think it will be troublesome for me to addapt to the new screen.
after a week with this phone, i love that screen... it is very hard to adapt first few days, but than, everything is so great... it is much better like resistive screen... typing is super fast, sliding is easy...
yes i am also having problems with the high sensitivity, but i'm coming from solid keys so no real surprises! starting to get used to it now. I reckon OP you'll get used to it to. Give it a week or so!
You'll get used to it and never look back, I have an i8910 at the moment (HD2 arriving in a couple of days), which is also capacitive and it just takes a little while to adjust.
Fine here too, although the Opera "flick scroll" is too sensitive in a way - it always seems to scroll too far for me, at least a whole screen, so not as useful as the iPhone equivalent.
Anybody know if that is tweakable somehow?
There are a few practical steps I have found that have minimised the problem (for me) while we restive users come to terms with the capacitive screens we have yearned for:
Don't press too hard - it's easily done in frustration but it actually makes things worse
Align the screen - I don't think the factory calibration is too clever (this made a big difference for me)
Switch to a different keyboard. After labouring with the default keyboard and finding myself in a similar place to the OP, I reinstalled my trusty TouchPal and all is well again
Thse worked for me - hope they are of use to others

Same sensitivity as Pro2 ?, lol. They probably got a broken sample.
On the Pro2 I was easily able to put my finger on the screen without a click being registered. With the HD2 we got confirmations this is impossible, as soon as your skin touches the device, no matter how lightly you brought your finger to the screen, a click will be registered.
I used to have a Touch HD beforehand, and after getting the HD2 I noticed I would make a large amount of mistakes, and that typing was extremely hard (especially on the go).
But like others have said, give it a couple of days and you will start to get used to it. I'm definately getting the hang of it. But I would strongly recommend you enable T9. Getting the hang of typing on a capacitive screen comes naturally.
And try out the horizontal keyboard; turn the HD2 sideways and the horizontal keybord will be shown to you. You may find it a bit easier to type on that instead.
This is the best screen i have in any windows mobile, the reason i had an iphone was the capasitive screen it has but now because of this screen i switched to the HD2 and i am more than happy and i don't understand why people complain about this screen its simply FANTASTIC.
I think I can uderstand them, it is beacuse we are used to looking exactly where we are going to click, now, with the capacitive screen, we have to use our finger to do it (wich obviously wont let us see waht we are clicking on). I was a little bit stressed yesterday that I received the phone, but right now I am getting used to it. I am doing now a slide soft motion with the screen, and not the old press hard movement I used to with my HD.
I think it is great, let give it at least a few days so we can get confortable with it.

Back Button Powers off screen?

I've been using android exclusively for the pass few days and have been really impressed with the progress that has been made on the HD2. I now find this phone to be less intolerable than when it was on wm6.5.
I have noticed i am using the hardware buttons a lot more in android. One problem i have though is that often when I use the "back" button it turns off the screen about maybe 30 percent of the time or so. I believe this because the buttons are not separate pieces but connected?
anybody else experiencing similar issues? Any fixes out there? Sorry if this has been addressed already in a different thread.
You have fat fingers
actually i have very skinny fingers. i only weigh 115 lbs. I have something else that is quite thick but if i used it on my phone i might crack the screen haha.
seriously though no one else is having this problem?
I think it's a hardware problem, maybe something (probably dirt) is stuck under your buttons?
I have similar problems with the back and middle button. It seems to be from them wearing out, which is happening a lot quicker since using android because the buttons are more necessary for operation. I've always been very gentle with my buttons, too. My phones in perfect condition except for the button issues. There's a couple threads around about the hard buttons wearing out... I don't think they were manufactured all that well personally... they don't seem all that stable. Most people don't have problems, but many have. Most newer android phones seem to use capacitive buttons. They are probably more stable that way, don't wear out easily, and have less manufacturing defects.
I've been thinking of sending mine in for warranty repair, because mine are progressively getting worse... yours might too. Or you can maybe set your volume keys as the back key. It would be great if some sort of onscreen back key could be made as that is probably my most used button.

Soft keys (back,home,tasks) stopped functioning.

Started having this issue on my phone 48hrs ago after it being left on the shelf charging from 5% battery overnight. So I'm using a 3rd party app to simulate the buttons for time being as a workaround (there's loads of variants on the Play Store that don't require root) until I fix it.
I had to replace a cracked screen on it a few months back (which was easier to do then I thought thanks to the iFixIt teardown. All has seemed well apart from some light blooms on the screen that I've lived with and now the buttons failing, and the part I ordered didn't come with the adhesive to reattach the back.
So I've now bought another screen\digitizer from amazon in the hope it'll resolve the issue and should be delivered within the week.
I've seen a lot of forums around the web for people with similar issues.
Tests tend to involve variations of safemode or factory resetting without restoring original. But this doesn't resolve the majority of cases, except the occasional temporary fix.
Solutions include; factory resets, flashing different ROMs, dropping at a 20degree angle, persistently hitting the buttons and re-seating a ribbon cable.
My thoughts:
It seems to me that maybe the Soft Keys area uses resistive touch section rather than capacitive touch, which would explain why the soft key touch area works in some instances but not others. It would also through weight behind it being a hardware issue. The capacitive multi-touch screen works fine, but the resistive section for the soft keys doesn't. Anyone have further thoughts on this?
Same without me
Easy test
Rotate your phone into secondary landscape mode. This will place the navigation buttons on the other end of the screen. From here, you will be able to perform the necessary tests to determine the validity of your theory.

Lol this doesn't make any sense, if it was a true you would be able to press soft keys with a pen or old stylus - this is how resistive screen works.
No part of this phone's screen is resistive. Sigh people that don't understand the basics of capacitive touch screens.
Thanks for the responses.
Yeah, resistive was a pretty far stretch of imagination, but I couldn't think what else it might be at the time.
Anyway. Replacement screen fitted and soft keys working again.:victory:
I can put off looking for a replacement phone for a little longer.
