Screen coming away from phone....

Had the TP2 for a week now, really impressed with it, but.......
the plastic screen on top of the touch sensistive screen has come away so when i click I can feel the plastic screen move about 1-2mm before it hits the touch sensitive part.
Has anyone else experienced this, if so is there a fix (heating it or something lol?) or am I in a possition to send it back?

Is this the screen protector that has come away or part of the screen itself?
If it's the screen protector that you have applied, then apparently you can take it off, wash it and air dry it then reapply. Having said that I've never managed to do it, I always end up buying a new one!
If it is part of the screen then DO NOT fiddle about with it, send it back!

I have the same problem.
In my opinion in the middle of the screen + left/right, there is less sensity than under and above he screen.
I think in this part of the screen the space between lcd and his plastic cover is bigger than elswhere.
I have tested it with resco explorer.
I have tried to marked some files from up and down and with a slightly pressure, the upper and under area recognized the input, but in the middle it does not.
Perhaps my Rhodium lacks,
and perhaps it is overstated?
No idea.
It would be nice to get some statements from you guys.
Sorry for my english

Exact same problem as me, I don't think it was like it when I first got it, lets give it some time and see if others experience the same problem - not sure if this will be covered by warrenty or not.

same problem for me. i can press the screen for about 1-2mm down. but only in the center of the screen.
sometimes there is a click noise, when pressing the screen in the center and under the speaker at the htc logo.
did anyone send it back?

do you mean ?
Do you mean that the screen in the middle is "wobbly" ?
I think I have the same Issue In the middle it feels like if there is some space between the plastic covering the screen and the lcd.
and no, I dont have a screen protector on it atm...

This "issue" that is being discussed here is known as the screen flexing. Unfortunately, this is an attribute of all resistive touch screens.

Im a bit relieved now. So it is normal to be like that or a problem with the screen that happens sometimes due to the nature of the resistive screen _

It's normal. All resistive touchscreens are like that (check out your/someone else's Nintendo DS, it's the same). The flexing is pretty good (ie, minimal) on the TP2. It's much worse on older generation devices.

thanks

Quick question/concern about the Tilt2's physical sturdiness.

First off, I just got my tilt2 from stores yesterday, and I must say, I love it so much! Just got a few concerns...
For those of you who have the tilt2, when the screen is tilted all the way up, is there a "looseness" of about 2-3 degrees? Meaning, theres just a small portion of the tilt2 at its most "tilted moment," so to speak, that it just wiggles back and forth for about2-3 degrees? It's not too big of a deal really as the current tilting of the tilt2 seems MUCH more sturdy (and it will probably last much longer holding its tilt feature), but I want to know if its a physical defect on my current tilt2, or that's just how its made for whatever reason.
Also, I am quite worried about how much looser the top screen portion of the tilt2 is from the bottom keyboard when closed all the way as compared to my original tilt. If I were to slightly use my hands to grab each separate part and pull them apart gently, it is easy to see that it easily lifts, and if I pulled any harder, I can almost break those halves apart, whereas my first tilt BARELY budged even after 2 years of use. Basically, everything about the tilt2 is better, but it seems like it won't be able to take much of a beating as compared to the tilt1.
Just concerned about inevitable wear-n-tear, and its effects itll have in the long run, or couple of months even. Thanks in advance for future input!

K

The 2-3 degrees of wobble is normal from what I've read. Mine has it too. It's slightly unfortunate, but doesn't really cause any practical problems.
I have read at least one report of a screen that can be separated from the body by a lot when closed. He said he could fit 15 (I think) playing cards in there, which mine most certainly could not fit. I never had a tilting phone before to compare to, but I am satisfied with my closed gap, which only goes up to about 1mm with light separating pressure. If your gap is much larger than that, it may be one of the less well attached screens.

I have the same problem with my tilt 2. Its abit annoying when you press in the screen on the left side of the device in portrait mode with the keyboard closed and the screen pushes in because of the gap but I don't beleive its a defect. I have seen some sturdier as my buddy's tilt 2 have zero play but his keyboard is hitting the bottom of the device and has scratched some keys so I would take mine any day. Plus I don't wanna chance it and take it back for an exchange as what you get may be worse.. IE - Dead pixel, screen QTY, keyboard lights, an even more loose slider, etc, etc.

Thanks for your reply, makes me feel at ease. Also, I think you've misunderstood, my gap is as small as you say, and from your words, it must be normal. It's when I intentionally put pressure on the screen and keyboard (not that I would do that on a normal basis, just for initial inspection purposes) that makes the gap wider. Though, I guess with a tilting screen like this, theres less tightness between the screen and keyboard. But nonetheless, all is normal. I was only concerned with those when I purposely applied my own force. I was not use to how much more delicate this machine, the tilt2, is as compared to my brick of a tilt1.

Yes, that was one of my que's from the start.
It was when the whole device was closed and I was playing with the touch screen, you could feel the screen go down a bit as I applied pressure to it. It was almost like if i pressed any harder, the bottom of the screen would just keep hitting the keyboard. But hey, glad to see that this seems to be a normal thing.

PS. Oh and yes, I noticed it when I tapped on the left side of the screen as well.

Another WP7 Hate Thread: MultiTouch

I HATE using the iphone that my friends have because i cannot use my nail. I am so used to using my nail since 2004. I wish they would have used resistive multi touch instead of capacitive.
Guess i will be keeping my TD 2 for a long long time.

Guess you are.
What's the point of this thread and why couldn't you just post your opinion in the "WP7 is complete fail" thread?
Capacitive are much better than resistive screens for touch screen phones and that's a fact(you just need to get used to them). For tablets it's the other way around.
It would be awesome if someone figured out a way to utilize both techs.

Read through the feature list of this touchscreen technology: http://www.atmel.com/products/touchscreens/default.asp?family_id=701
The eleventh bullet point states: "Supports stylus, fingernails, and gloves". BTW this touchscreen technology is used on the HTC Droid Incredible and the HTC EVO. Maybe you could test if it works on those screens if you come across either of those phones.

Doesn't work according to owners of the incredible.

There are resistive screens that support both nails and multitouch.
They are not supported by Microsoft however. But we might see them in other (e.g. Android) phones in the future.

I don't expect any Android phones with resistive screens from any of the bigger Android supporters in the industry, like HTC for example. HTC has said that they learned from the HTC Tattoo to never do an Android phone with a resistive touchscreen again. It's simply too much of an inferior experience and that makes the higher cost of a capacitive touchscreen worth it.
The problem with a resistive touchscreen is that it reacts to pressure and not to contact. That's precisely what you need if you want to operate the touchscreen with your nails, but it just doesn't work well for all other touchscreen user interface manipulations. It's just a much more pleasant experience if the screen reacts to your input without having to barely do anything, it makes using the touchscreen a much more delightful experience.
Another problem with a resistive touchscreen is the fact that because it reacts to pressure, the screen need to be flexible. This means that you can't use a tempered glass screen or something similar on a resistive touchscreen device and you can't (or it's very very hard to) make a device with a touchscreen that's flush with its bezel. The former means that your screen a more prone to scratching and also that it makes the underlying screen a bit more vulnerable to damage.
Now I agree that a capacitive touchscreen also has its drawbacks, but for a mobile phone or a PMP a capacitive touchscreen and a finger friendly user interface is preferable in my opinion compared to a resistive touchscreen. There are other market segments and usage scenarios where a device with a resistive touchscreen is preferable to a capacitive touchscreen, for example in Postal Services where the mail man can collect a signature from you on his portable device that features a resistive touchscreen or in restaurants. But for a mobile phone I'd prefer a capacitive touchscreen simply because it's much easier to use and I don't need a stylus (too cumbersome) on a mobile phone.

This is not a resistive vs. capacitive discussion. I much prefer capacitive on phones, but here's a user who wants to use his fingernails. Hence I was just stating the facts: Microsoft does not support anything but capacitive, but we might see new resistive panels on other phones (that are different from and much better than what was used in the tattoo).
Whether you like resistive screens or not is another story.

I've never used a capacative screen so I don't know if I will like it or not. I don't have fingernails but I do like using my pencil or stylus in class while doing math problems on my spacetime graphic calc software so It'll be interesting to see how I feel about a capacative screen.

Resistive great for sweaty palms
For a guy who's hands sweats alot, I actually had to give up my blackberry storm for a Touch pro 2... Now, I agree that the capacitive screen is very easy to manipulate but when my hands sweat 85% of the time, a resistive screen is a godsend. While the percentage of sweaty palms vs normal palms is probably very small, capacitive screens turn to shyte when water gets on it.... and when that happens, it's like I have a brick...i cannot do anything... even if my hands get clammy, the difficulty in typing or navigating the screen is "hair pulling" awful.
To be honest... I really love using my nails and a stylus... plus you have to admit...pullng out a touch pro 2 in a meeting and then using the stylus...It just brings a green hue to the room (envy) lol!

Don't feel bad, I have Hyperhidrosis too. Probably the main reason I hate capacitive, anything I touch turns to a smudgy mess. I know you can use a stylus with a capacitive screen, but it really feels awkward with the 1cm^2 tip and the lack of precision of a real stylus. Also it's not contractable and easily stored in the device since it's not the norm to have a stylus with a capacitive screen.

I reckon y'all have got girl fingernails.
Come on guys, trim those nails, and would it kill you to use the fingernail brush every once in a while?
Capacitive screens Feck The World!

you don't need a long fingernail to touch your fingernail against something...just turn your finger more so your nail makes contact with the surface before your tip does. Unless of course you have unsightly hands where your meaty part of your finger encapulates your fingernail.

Looks good , very well done!

I know they have resistive multi touch but its probably too expensive. I might end up switching to another company for phones and i would hate too as i have been a HTC user since the wing. The capacitive glassy feel is not for me, and a stylus is a must especially for drawing and hw recognition which the hd2 and iphone have none of.

I agree. I'd also rather use my stylus because I want my phone like a mini-computer. It can't use a mouse for pin-point accuracy, but a stylus sure suffices.
I understand the world is going to capacitive touchscreens and it's a shame. I always liked resistive better. It's more accurate. I know that people want to use their finger tips to swipe and sweep and whatever, but there are plenty of limitations out there to it.

You guys could always use a capacitive stylus. Remeber capacitive screen works by detecting a change of charge in the screen. Basically things that can conduct electricity should be usable as a stylus. If you're smart, you wouldn't find it hard to modify any stylus to make it work with a capacitive screen.
Else, you could buy any of the capacitive styluses online, which usually cost 3-20 dollar-ish. The fluffy tip is the best as you don't need to hold it at an angle.
I'm still waiting for my HD2 currently, and I already ordered that stylus in advance

Yeah, but the capacitive stylus feels nothing like the resistive ones.

Is Capactive really BETTER than resistive?

Most of the latest smartphones and upcoming phones appear to have capacative screens and they seem to be the preferred type. However, I still use a resistive screen and I recently borrowed an HTC HD2 with capactive screen and I was not that impressed.
Certainly, they do resopond to a lighter touch but for me that was an irritation as I would regularly accidentally touch/select something by mistake. My Touch Pro2 resistive screen does not require much more pressure on the screen but just enough that it is hard to select something accidentally. I also like to use my finger nail to select which of course you cannot do with a capactive screen. Selecting some of the smaller menus in Windows Mobile is quite difficult on a capactive screen.
The other reason I like using my finger nail is to minimize finger marks on the screen. I noticed when using a capactive screen that it was covered in finger marks very quickly.
So, are capactive screens really "better"? I have held off upgrading my Touch Pro2 as I do not think that capactive screens are better than some of the latter resistive screens. However, it seems that if I do want to upgrade my phone in due course I am going to have to go with a capactive screen.
Maybe my Touch Pro2 will serve me for a while longer yet!

Apparently I heard the Capactive screens dont have as accurate of touches either. But then again you have things like pinch zooming and stuff to that nature. With phones these days its all a give and a get. Your problem with thumb imprints, a lot of the newer screen protectors dont get thumbprints. My friend has an Evo with a Anti-Glare screen and he uses it so much that he carries arond two batteries with himself at all time, I have never seen a thumbprint on hisphone. Maybe its the anti-glare or the type of shield? I'm not sure. But with a damp cloth the prints go away quite easily

i never saw the benefit of pinch zooming either, it just seems like now i need 2 hands (one to hold the phone and one to pinch) to do something that only took 1 hand (double tap with my thumb while holding the phone in the same hand)
i felt that way about a lot of iphone "features" to me it just seemed like an extra step or more complex way to do something that was devised solely to justify the capacitive screen and say "looks its new and different, therefore it MUST be better!"

I'm a heavy user of Remote Desktop. I got to really sit down and play with my friends HD2 yesterday (capacitive screen). I found that I hated it. At first, the pinch & zoom with RDP is cool & looks impressive. In actual use however, I found it cumbersome and potentially dangerous. While playing with the pinch & zoom a few times with Windows Explorer open, I accidentally picked up huge chunks of my folders and dropped them somewhere else... Pressing small dialog boxes with my fat fingers was nearly impossible, and the program itself was buggy and cumbersome (sometimes very difficult to scroll to the corner to hit "X" or Start", etc.)
I'm sure some clever programmer could find a way to use these features effectively, but since WM 6.5 is essentially dead, I have to consider that this might be the *only* RDP client ever made for the HD2, and I found that it just isn't good enough.
I suspect my feelings about this will apply to many other programs when using a capacitive screen with them.

I think capacitive screens are good for telephonic use (big keys and little messages). For office use, stylus and keyboard are unsurpassed (little and accurate selections and long texts). Obviously many users are interested, understandably, to phones and producers prefer to sell more capacitive phones than a few pdaphones. Problems will come with professional and power users.
Imho.

From what little I've used them I can't stand them. I like pressing with the tip of my fingernail which obviously doesn't register. I also use the stylus quite a bit for scribbling quick notes and drawings. I've got pretty massive hands and going to press on a keyboard key is really hit or miss.

Why capacitive screens?
Because the industry follows the idiots at Apple. If apple releases something, they have to, because they are afraid of losing market share.
I'd like to see them come up with something apple DOESN'T have and spin it like his PR buddies do.
It's amazing... the iphone 4, when it was released and myself and a few of my
amateur radio buddies saw the OUTSIDE band that was an antenna we all started
laughing that it would probably have signal degradation, and sure enough, it did, because when you put your finger over the "spot", you change the wavelength of the antenna.
I'm just glad it was found to be imperfect BEFORE everyone jumped on THAT bandwagon, like they have with capacitive screens.

i think its a personal preference. I for one enjoy resistive. i like having the accurate point to highlight text where as its a pain to select text using any capacitive screen.
My gf recently got the Evo and i'm constantly pressing thing accidentally. also for the ipad, since its capacitive, thats why it doesn't have handwriting recognition. the only reason i considered getting one was because i could load up all my textbooks for my classes which would make it easier in several ways. wouldn't have to carry around a bunch of books and you good search for keywords rather than flipping through and trying to remember where that one paragraph was.
I know you can highlight, but to add notes, you have to use an onscreen keyboard. would of been much better if there was a stylus and you could just pull that out and jot down a couple notes real quick. but since its capacitive, no can do.
there was a blog (can't remember which one) which contained an article about how a new phone was coming out and the only bad thing about it was a resistive screen. The comments went ablaze with posts like in this thread. each has its pros and cons, but i prefer resistive.

I like using a stylus to tap smaller screen elements, especially with programs like remote desktop. However, after using resistive screens for the past five years, I reluctantly went capacitive with the Evo, and I have to say it wasn't that bad. I like that the screen is no longer squishy, the glass won't scratch when I clean it off my shirt, and multitouch makes it easier to zoom in to the exact size you want.
And while the Windows rdp program requires excessive pinch and zoom, the one I use on the Evo has a virtual mouse pointer, so I never have to resize the screen and I can click on even the smallest elements. I can also use my finger for larger things.
I'll see how I feel when it's 10 below and I have to answer my phone.

thats true.
Last winter and it was freezing, all my iphone friends had to take they're gloves off to use their phones (although there are gloves with a static point at the end that will work on capacitive screens) but i was fine with my tilt2 and gloves. Also swype is a lifesaver in the cold and when your wearing gloves, find the right gloves with a nice point at the end, not too blunt, and works perfectly!

Gaming and other multi-touch?
Gaming is really the only advantage I can see to using a capacitive screen; that is, the fact that you can easily have multi-touch controls. There's also the benefit of multi-touch gestures that can be useful- but these all still seem pretty buggy and somewhat of a pointless novelty where I have read about them being employed. I personally do not ever want to use a capacitive touchscreen device as there is just too much sacrifice in functionality. Sad that the market is moving hard in that direction.

[Q] Xperia arc screen too sensitive?

Hi all,
I simply love this phone, but I'm facing a situation that my screen is too sensitive. The home screens were so sensitive a few programs were started without my knowledge. It got better after I switched to Launcher Pro.
However, it is still too sensitive in other areas. When I'm scrolling down, say, the apps in Market, I'll always end up selecting a few items accidentally before I reach the end of the list.
I've used HTC Desire in the past and I'm quite sure the problem is not due to me.
Does anyone else face the same problem, or I have a hardware problem? Or software problem? Can I be tweaked by any means?
Any feedback would be useful! Thanks!!!
KG

I faced this problem before... while swiping, apps accidentally open. But instead of "too sensitive" i thought it's insensitive... because a short swipe was sometimes interpreted as a tap (maybe because the swipe was not fully detected?).
Anyway, I had 2 layers on my device... the pre-applied sheet and another screen protector that came with the box.
I removed the second layer, leaving only the pre-applied sheet, and all is well again... no more accidental "taps"

That was how I solved my problem. I actually put on the spare screen protector because when I got the set I didn't realize there was already a pre-applied layer.
Don't blame me if it doesn't work for you

perhaps some of you guys just have the shakes?! ;-p

I guess the screen is never to perfect for everyone.

kargtan, I've noticed the same about the tap sensitivity - I often accidentally "tap" when I mean to swipe. Came from an iPhone 3g and didn't notice this on that device. Might be a matter of getting used to it, not sure. Have you gotten any feedback from others in other forums?

I've noticed this too, and put it down to the screen protector. It's not android OS causing it, never had the problem on my htc hero...
However, now that i've gotten used to the phone it doesnt do it any more - guess my brain has automatically trained itself to drag the screen a little bit more firmly or something.
One thing i have noticed about the arc is: because the bezel around the screen is so thin, i often accidentally launch apps just by holding it. My fingers wrap around slightly & touch the edges of the screen.

Does any of you have problems while trying to swap a screen from another and instead of swapping you get like a "bounce" and stay on the same screen? because that happens to me all the time, I came from an htc Legend and this is making me crazy !
btw, this happens to me if I hold the phone with my right hand and try to do the swapping with my thumb, the only way to get it right is to hold the phone with my left hand and use the index of my right hand

Screen too/not sensitive
Hi guys,
I think the problem arises from the slowness of the phone, not "too sensitive". I used to use the HTC Desire in the past and I was very used to the screen scrolling very quickly. In contrast, the arc is slower and hence the screens don't scroll as fast and hence my way of handling the Desire would cause the problems stated.
I did a few things since my last posting and it seems better now:
Replace the SE Home with Launcher Pro - this seems to have improved on the speed of the phone, and hence better responsiveness to the touch.
Rooted the phone and uninstalled some stock programs.
Removed useless widgets on the desktops.
Adjusted my way of scrolling as someone has suggested.
This is quite frustrating at times, especially so because other than this problem, this phone is a gem, especially its form factor, the sound quality and most importantly, the quality of the camera.
I might sell the phone once the company issues me with a Blackberry (DANG!), but I am kinda unwilling because I have been taking lots of photos with my Android phones and these photos are generally well-liked by my Facebook friends.

agree with bezel thing and hard to use thumb.
noticed arc screen (the screen guard perhaps ) easily get oily and slippery.
had to wipe phone and wash hand so often that make me like some sort of disorder.

Don't know why you guys seem to be having problems... I don't have any issues with my screen swipes at all... smooth and fast.. both on stock and Launcher Pro..

Same deal here. But that's because the screen is sensitive beyond the display area including the black border, and the edge is too narrow. When I use one hand swiping or tapping, the palm of my hand touches the black border. The screen registers two touches in quick succession and thus jumps.

In Phone keypad, enter *#*#7378423#*#* (the numbers mean SERVICE word in keypad), you can go into test mode. Select [Service test]->[Touch Screen] to test the badly touch screen of SE Phones.
You will discover when you swipe the edge of touch screen, the touched result is very not satisfied. The lines you swiped will not accurate and appear like jags, or stick on the edge of the screen.
The touch panel made in China...? ;-)

Me too!
Hey!
i also have a xperia tipo....and i too have the sensitive problem

Could also be a kernel problem?
I remember I installed a kernel a while back that would make my screen hypersensitive; just hovering over the screen would already activate it!
I don't remember which one, it was back in the GB days. But I'm pretty sure it can be changed in the kernel.
