Screen pressure problem!

Hello.
I have a Qtek 9000 and i would like to ask a question.
Generally the screen needs a quite soft press in a button to work.
But in my device, i need to press a bit hard whenever i want to select something in the middle of the screen.
I mean that it needs more pressure in the middle of the screen than in the rest of the screen for it to work.
Is there a problem with my device or is it normal?
Thank you!

I don't seem to have that problem :-/ a light tap will normally be detected anywhere on my screen.

Ok, thank you!
Anyone else's experience?

Do you have a screen protector? Maybe it is thick in the middle. Try taking the screen protector off. It may work.

Yes, with the protector the problem was big.
Now that i have removed it the problem is almost gone( now will be difficult not to scratch the screen without it, but i prefer to have the phone working right).
Thank you!

Try the "Fellows" screen protectors. It is thin and comes in packs of 20, I think. It is like a transparent sticker. Better than not having one.
On my Exec, I use Proporta's Screen Protector. I think it is scratch resistant. I have it on since I opened my Exec fresh from the box and it still looks brand new without any scratch on it.

Thank you, but i am afraid i will have the same problems.
I usually use Brando Screen protectors which is top quality (100% transparency) but in this case it seems that i can't do anything.

Screen Protectors
I personally don't see the use of screen protectors. I have had ~6 PPCs, have never used a single screen protector, and have never had a scratched or damaged screen.
Am I just that much more careful than everyone else? I think not! :lol:

My personal experience(after using over 15 PPC/Palm devices all these years) is that if you tend to use handwriting recognition or any other functions that require to "write" on the screen frequently, then it is virtually impossible not to scratch the screen.

Edges of screen unresponsive?

Anyone else notice that the edges of the screen on the cmda diamond, cdma pro, and the HD seem to be MUCH less responsive than the screens of previous devices?
I "miss" the exit and start menu buttons pretty often and its pretty annoying lol.
Also the notification/title bar area plus other buttons along the bottom and side.
The rest of the screen is more responsive certainly than say the vogue, mogul, diamond or tp. But its the edges of this and the last 2 mentioned devices that get me..

Well I also feel it's less responsive, but not so much actually. Besides this is caused by the technology of the touch screen.

You mean the edges or the whole thing? The main part I feel is more responsive...

Edge responisiveness depends highly on screen calibration. Try to recalibrate screen more precisely, I think situation should improve ...

Hey thanks a lot. Thought the same thing myself.
Re-calibrated as accurately as I possibly could.
Still no go. I would really like someone else to try this. Take out your stylus even and press in the very corner of the X-button...you get nothing.
Sort of fix: I found that if you hold your press just a little longer it registers (much better) though I'm not quite convinced that it's still normal nor complete.

I don't see any problem in pressing X-button on my Touch HD. I had similar problem like yours using right vertical scrollbar and recalibration helped, so I though it might help you too, but unfortunately it seem this ain't the same problem

Hmm...I wonder if I should try to get it replaced under warranty.
I would want to, but I have noticed the same problem in a sprint diamond in the store, a sprint touch pro in a store, and a friends sprint touch pro.
What do you (guys) think? Replacement? It could get really annoying...not being able to close out of things. Right now since its new and awesome and stuff I'm kind of trying to ignore it or whatever but...hmm idk.

The fact that the screen is less responsive near the edges is caused by an inherent technical limitation of resistive screens. The screen has no real bezel, and thus, the screen is attached to the body frame right where it ends: at the absolute edges of the screen Where it is attached, it cannot move. A little further away from the edge it can move (eg be pressed down) but this requires more force since you need to bend the screen much closer to the fixed edges than when you would press the center of the screen, which bends the easiest.
Don't know if this makes sense, but it's like a window... Hitting it in the centre will break it much easier than when hitting it close to the edges, since the glass bends much further/easier at the center, so the same force will have more effect.
Anyway, resistive screens have this problems, capacitive screens do not, obviously, since they do not rely on pressure.
If hitting the OK/Close button is a problem for you, just use the hardware button below the screen, the one with the arrow on it. It does exactly the same thing I believe. With 'I believe' I mean I assigned OK/close to that button using AEButtonPlus, which should be the default behavior for pressing it once. I find this to be much more convenient than trying to hit that tiny X/OK button.

Hey thanks for your informative opinion.
This theory seems to fit, except it doesn't quite explain nor fit with these 2 things:
1. I can apply a pretty decent amount of pressure in the corner with no results whatsoever. But I can get full results if I apply less pressure for about .5-1 second rather than just tapping.
2. I have never seen any evidence of this on any other resistive touch devices (vogue, titan).
Why in the world do these resistive touch screens have to suck so bad anyway? The HD is the best I've seen lately, but does HTC just suck at it, or is it everyone (haven't owned a non-htc ts device for a yr or so, and that was a treo where I didn't really notice sensitivity).
My dad has a 3+ yr old Dell Axim X5 and that screen is AMAZINGLY sensitive. Responds to stylus and is too old to be capacitive. But it is literally 100% as responsive / sensitive as the screen of the iPhone. When I used it I couldn't believe it. You had to be VERY delicate and careful and trying hard to touch that screen and not have it know.

Adjust screen sensitivity?...

I have been searching for the past few hours but have found nothing on the subject...
Does anyone know how to increase the sensitivity on the Sapphire? Is there a way to disable the "heat sensing" part of the touch screen (my wife has acrylic nails and a stylus doesn't work either)
Thanks
MrCheese

You cannot change the capacitive screen. So no nails and stylus...You can get a Tattoo (resistive screen)

but what about the sensitivity?
is there a way to change it?
the rom i'm currently using seems to have made the onscreen keyboard less sensitive when in landscape mode.

I think I read that external power source = greater screen sensitivity, I doubt that will help you though.
I have added a screen protector today and it seems to have had a positive impact on the screen responsiveness. When playing games my screen pretty much went dead form all the finger print grease. Glasses cloth ftw.
Edit: Have you turned off vibrating keys? nice as it is it definitely made me miss key presses.

why does the screen "shivers" when i place my finger on it...

i have applied the de-sensitive cab but when i use my finger to press down and drag selections, i can never be precise .. the screen starts to "shiver" around like Jack from the Titanic ...
hmmm is there any tweak to reduce this?
BTW, do i need to align the screen regularly?
thanks!!!

appreciate any help on this

I too have the same problem. I have read the other exhaustive thread on screen problems but couldn't come to a conclusion. Is this a software issue or hardware fault?

Do you mean the built in tactile feedback vibration where the screen buzzes to let you know it's been touched?
Settings/Personalise/Vibration/and then uncheck the box

Try the screen sensitivity reducing tips, or better still use BSBtweaks, it has a toggle to reduce sensitivity that works.
also, i found being too gentle with my fingertip makes it juddery. a firm press with the pad of teh finger works better for me than the tip.
I align my screen after any hard reset / rom flash.

i had this issue too, it appeared suddenly a few days after i upgraded the radio on my previous rom. with the current combination everything is in place now.

I would say it is a hardware fault. My first HD2 was perfect with no screen sensitivity issues. Unfortunately, it was accidentally damagaed and I had to replace it. The replacement unit did suffer from the sensitivity issue and although the sensitivity fix improved things substancially, it it still wasn't anywhere near as good as my original unit. So it went back to the store and they game me a replacement which I am happy to say doesn't have the sensitivity issue and is a joy to use again.
The new unit does however have an uneven backlight but I'll probably live with that as it's the lesser of two evils!

omg why cant they built it right one time!

Are you guys using a screen protector?
I used to have perfect screen behaviour. Recently, I saw the multitude of cheap 3 for $x screen protectors, and tested about 8 different brands.
Some were pure crap, didn't prevent fingerprints or oil...
The mirror ones and some clear ones killed sensitivity!!! Made my touches jump all over, my presses inaccurate.
Some matt screen protectors were too thin and were absolutely useless (and easy to scratch).
Only a few were good enough not to cause a problem.
Can only suggest you try remove the screen protector if you encounter the same issue.
Cheers

Unfortunately this is a known problem:

Getting the device changed has helped to reduce this in some cases.

i was trying out the iphone, i noticed
iphone screen is matte.. no stickiness if sweat and swipe is smooth..
hd2 glossy if you sweat, you get friction... swipe depends on friction
if i were to put a matte screen protector, maybe it helps? anyone knows about this?

IPhone 3gs and HTC Hero both have an oleophobic coated screen which greatly reduces fingerprints and smudges. HD2 does not. Don't know why HTC don't use this tech on all of their capacitve screens.

ok i used a matte screen protector... result = smoother flicks and less finger prints.. but shivers is MORE...
hmmm what is wrong with our screen? * i tried iphone... NO ERRORS in typing..
could it be our software compensation for errors is screwed? u know as in the software is predicting the center of the finger wrongly

all people i know has this issue i think it is software htc is not a fool company to release all devices defected

and i wonder why they take so long to fix it..

Touch screen issues after removing screen protector

So I removed the included screen protector since it had a deep scratch on it. I read on the forums that you don't need the protector and that it actually works better without it.
Well my experience has been the complete opposite. Ever since I removed the protector I'm ready to smash this bloody phone. It's next to impossible to use due to the humidity in my area or something. The SMALLEST amount of moisture on my finger tips or even in the air will cause the screen to go haywire and register touches all by itself. Apps will open by themselves...i can barely type anything as it keeps typing multiple characters on it's own or other silly stuff. If I wipe down the display it will work fine for the first little bit until it gets that tiny bit of moisture from my fingers on the screen again and it starts going haywire again. It's a hassle just to try and unlock the phone from the lock screen at times.
So is my phone defective or is just the suffering I must incur by living in a humid area. I can't use the phone like this so I guess I'll have to look at buying a new screen protector. But if this is not normal and is a fault in my hardware then i would like to return it and get a different phone. I didn't really have issues with the screen protector on.

Ive kept my screen protector on my phone, works fine until i have moisture or (rain drops) on the screen, then my phone doesnt respond and also misfunctions the position of where i touch on the screen not sure if this is normaly as its the rain drops on the screen..
Tested witht he iphone 4 in the rain and works brilliant, why doesnt the X10 do the same !! :/

As you may know, those screens are capacitive displays, that means they're activated by sending (very) small amounts of electricity and are kinda "looking for a conductive material" in order to register an input.
The conductive material can be your finger, or something like... a raindrop or your screen, so that's why it thinks you're pressing that part of the screen...
Now it's even more obvious without the screen protector since it's directly on the screen.
As for why the iphone doesn't have issues with that, it does, but the screen being multitouch it's not as bad...

thanks for the info.good to know.

I didn't like the thick screen protector as my thumb/finger seemed to drag and not slide smoothly. I took it off and replaced it with a slightly thinner protector. I'm much happier with the feel now.

@smok3yjk - probably best if you do as Angelahp - get another screen protector on there.
