wobbly screen?

Ok, now when I tilt the screen of my touch pro2 up, it has a slight wobble (in the direction the screen tilts, not sideways). Is it normal for a tilt screen device to have this "freeplay" from new?

Hi All
I have the same problem. My screen wobbles too. min 5-7mm "freeplay".

See my post yesterday
http://forum.xda-developers.com/showthread.php?t=524432
Just had blokey on from the company saying it was normal for the TP2. I must have had a good 4-5mm of play when it was tilted which seemed odd as my Kaiser was (and still is) totally solid with no play at tilt.
It would be really useful if people could post to say whether they have any 'freeplay' or not when tilted.
Thanks
John

yes freeplay here about 10m i would say its very loose

even 10mm is super loose
i think becoz it use different mechanism.

Have logged a call with HTC supprt to get the definitive answer, to wobble or not to wobble. Will update this post when I get a reply

Sent my unit back today and hope to get a replacement soon.
There was something seriously wrong with my unit.

tiinking of sending mine back to be replaced not only does it wobble in tilt but with the keyboard closed if i holed the phone flat of my hand and put slight pressure on the top left corner the screen slide about up just on one side is this normel so the screen can look off set

mine is loose but that is normal as you can't have the screen too rigid in tilt position. also its on hinges and that will have a part to play with the wobble. remember the screen is attached to the body by a ribbon which needs the screen to have that bit of play to take tension off the ribbon. when in tilt position look at the back of screen you will see the black ribbon. wobble the screen and you will see the kink in the ribbon when wobbling. now imagine having a really taut screen and the pressure that would be exerted on that ribbon. wobble is acceptable as it plays an important role! thats my opinion. i have a kaiser/tytn 2 and the screen is very wobbly and loose.

I second that Shingers,
My Kaiser became very loose after about one year.
The Rhodium looks to have a much more robust design though and yes there should be some amount of free play.
Time will tell how good the redisgn of the tilt mechanism is though.

Beasty

My Hermes has the same wobble since the first time I got it. 2,5 years later, it's still working great. Don't think it's a lot to worry about. or the people who don't have the wobble, it probably will be there in time.

yeah yours defo looks like one of the hinges are loose. that needs to go back defo. might just need tightening but i'd request a replacement if i were you! good luck with that

thanks for the input guys,
John, let us know what's the official position on this. Apart from the wobble device is working fine so I decided to keep it, it's not a deal breaker for me - i operate it while flat anyway and it stays tilted when put on the desk.
The looseness is like, when you tilt it and shake back and forward slowly, it eventually goes down in 3 shakes. Using the touchscreen when tilted is impossible unless you have a finger behind it.
I don't know, all the reviews are praising the stiff tilting mechanism of TP2 and online videos show people applying a bit of pressure on the device to tilt the screen, mine is not like that, that's why I started the thread.
It did say it's the first batch here in UK on the MFDirect website, so could be an early flawed version.

Will do, still waiting to hear. Just think its a bit disapointing if this is a part of the design as (and I really don't want to take anything away from the brilliance of everything else about the phone & how much people, including me seem to love it) it makes it feel, well cheap.....which as you say was the opposite of the reviews the phone has got from everywhere else.
Maybe mine was a lot looser than others have experienced? maybe I'm just a fussy ba***rd, don't know?
MPD won't replace it as they say it is normal, I'm waiting for it to come back then I'll send another email with a couple of snaps/video to HTC to get the definitive view. Will keep you up to date.

And waht about this,it was a little hard for me to explain it corrctly,so i'v take a picture
is it normale ?
http://img38.imageshack.us/img38/4057/tp2a.jpg

yes i think it is. Its the part that slide's out and also can be tilted. That means that it isn't attached to the bottom of the device and i guess that is wat causes the problem. I also have that problem a bit.
When i slide the device out and NOT tilt it it looks perfectly straight, but when i tilt the screen it wobble's a bit but i guess thats normal to..

same problem ..... same wobble .... still i love it

Thanks guys so i will love more my tp2

The definitive view part 1
Hi all
HTC have replied to my first query. Posted below. Basically there should be no looseness/wobble. I'll speak to them and MPDirect and see what happens next.
'Thank you so much for contacting HTC Technical Support Team.
Regarding your request, kindly note that the symptom you stated (the screen when tilted was loose on its hinges and wobbled back and forth by a few milimetres ) is not a normal symptom. the Screen should be firmly in place.
For further assistance please don't hesitate to contact us on our hotline < 0845 890 0079 > or visit our website at www.htc.com .
Respects & Regards,
HTC Technical Support Team.

screen not sensitive: manufacturing fault or unreal expectations ??

every review i've read online before i bought the unit was boasting about how "finger-friendly" the TP2 was, and that you could lightly swipe your finger across it to navigate the menu and that the touchscreen was very sensitive and whatnot
however after 2 weeks of use i find that to be relatively untrue. i've got to apply a fair amount of pressure on the screen to get it to register my input. of course, i'm posting this because i'm afraid that i might be damaging the screen in the process
i have no basis for comparison actually, my only 2 other touchscreen devices at home are an iphone and a cowon s9, both use capacitive screens. i always knew there was a big difference between capacitive screens and resistive screens, i just didn't know it was THIS huge. i can actually slide my finger lightly over the iphone's surface and its registered properly. the sliding probably feels smoother as its glass, but i can live with the TP2's plastic. what do you guys think ? should i get it checked out at the HTC store ?? its on the other side of town, don't wanna waste a trip as if its not a problem
oh yeah and just to get this out of the way, the screen is a membrane and not a hard surface right ?? everytime i press on the screen using my finger or the stylus, i can feel the screen slightly moving down, can also see the surface getting slightly dented at the point my finger pushes it if looking at it from a certain angle.
ps before somebody asks: i only got to test the keyboard at the telco store, some punk had cracked the screen of the display set, so i didn't know about this screen issue until i actually purchased the set
sorry for the long post, but i'd really appreciate any comments
TIA

Well, I don't have an Iphone so i can't tell you about how it compares with the TP2, however, i found the display to be much better than the one on my old XDA. It will probably never as good as a capacitive device like the touchpad on my laptop, but I found it to work very well. You have to apply a certain amount of pressue to the display, because it reacts on pressure, so I guess there is nothing wrong with that. I also see a small dent when I use the stylus and press the display. I cannot confirm the screen slightly going down when pressing it.
To summarize it, i use the Stylus 90% of the time. It glides much better on the display than my finger does so the overall experience is slightly better when using a stylus. Plus i don't get any greasy fingerprints on my display.
However the 10% I use my fingers to work on it (and 25% of that 10% is spent on polishing I found it to work pretty well, so in general I don't think that the reviews were off when it comes to finger usability.

What you are describing is probably normal. Resistive screens do require pressure. The TP2 tends to require less pressure than others, but nonetheless it does require it. There's no comparison if you compare it to a capacitive screen device because those don't require pressure at all.
The flexing of the screen that you described is something all resistive screens have. Again, if you compare the screen flex of the TP2 to earlier HTC devices, it's greatly improved.
To be on the safe side, go to a store and try out other resistive screen devices and see if you experience the same thing as your own. Then you'll know what is considered "normal".

thanks for the replies, i'll probably head down to my telco's store and see if they've replaced the display set then.
any other comments ??

You know I thought the same, waiting for a cab to increase the sensitivity because at the moment its quite annoying pressing buttons more than once...

From a few years to nowadays i´ve always used QTEK/HTC devices, my latest one is, ofcourse, HTC RHODIUM, the rom it has installed is RUU_Rhodium_HTC_PTG_1.19.410.0_Radio_Rhodium_3.44.25.27_Signed_Ship, and the screen is very sensitive and responsive, i´m just very pleased with it overall, it´s the best.
Cheers.

you don't need .cab
just change in registry...
HKLM/drivers/Touch Driver/pressurethreshold, (default=10000)
(I might not remember perfectly, but it's something like that)

try this?
http://forum.xda-developers.com/showthread.php?t=469865

this might help just re align your screen again using little pressure then your screen will not need some much pressure to work.
I have found the this not only aligns the screen but the pressure as well.
mine I just have to lightly touch it and dont have to press very much at all.
Cheers

Tilt 2 Screen Bounce

Just out of curiousity, do any of your screens have a kind of bounce or mushy feel to them when you press on them? I look at mine from the side and there is clearly a movement up and down when I push on it. I also have the screen protector on it too, but that should be firmly emplaced. It looks like from looking at it side on at the center of the screen is sort of unattached whenever I depress on it. Is this normal?

Same here
My mesage should not be to short to post now BOARD

It's perfectly normal that your touchscreen dips a little when pressed on; In fact, that's how resistive touchscreens work. From Wikipedia:
Resistive touchscreens are composed of two flexible sheets coated with a resistive material and separated by an air gap or microdots. When contact is made to the surface of the touchscreen, the two sheets are pressed together, registering the precise location of the touch. Because the touchscreen senses input from contact with nearly any object (finger, stylus/pen, palm) resistive touchscreens are a type of "passive" technology.

It seems to happen on all phones where the screen is on a slider. I've seen it on the Fuze and Kaiser, too.

i think the OP is about the screen itself, not the top half of the phones. the screen thing is inherent and i've got no issue with that, but a shifty sliding mechanism is annoying, though not present on my tp2

Yeah, however, I would have thought the screen would have been a little tighter in terms of it's air gap between the resistive layer and the LCD itself. I used to have an 8525 and there was never the kind of airgap between the touch screen and the LCD at all. With this there is a noticable gap in the touch screen layer to the LCD. Especially in the middle. I just would have thought it would have been a flatter tighter stretched across the screen.

[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"

For my case, maybe 2 layers is just too thick

I'm having the same problem. And that solution seems to make sense. I would give it a try, but if the problem still occurs, I'd be wasting one screen protector..

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.

[Flex] Wondering if I should get my HOX replaced

Last night while using the phone I noticed this slight clicking sound from the bottom right corner of the screen (touch-sensitive panel). So I kept pressing it and I wasn't hallucinating, its there. Also figured the sound also comes when I press the bottom right or bottom center edge of the phone. The creaking sound isn't loud but its noticeable when I hold the phone in specific angles and while typing if haptic feedback is on, I think the vibration also makes it happen(weird)
So except for this my HOX is fine and am wondering if I should get it changed.
Are there any long term effects to this? I'm starting to just ignore the sound and trying not to make it happen purposely

Depends, does it make the sound when you're using it normally? If it does I would consider swapping it, although you said everything else was fine.
If on the other hand, it makes the sound if you hold it in a certain way and push unusually hard then I would say stop intentionally pushing it in a weird way and use it properly.
People have been complaining about "screen flex" along the side of the phone when they push on the edge and run their fingers along the side. Want to get rid of the screen flex when you push the edge of your phone and move your finger along it? STOP PUSHING THE EDGE OF YOUR PHONE!!!
Just remember that some phones have had screen flickering, yellow marks and even scratches under the screen, you may not be as lucky as your were the first time if you choose to swap it.

what you described is not flex even, most mobile devices have a creak some where
Flex should mean the screen is literally loose to warrant an exchange

The only time I've noticed this sound while using the phone is during haptic feedback from typing on the keyboard. I switched haptic feedback off to save battery and for this 'problem'

I did reduce pushing it intentionally since last night after figuring it might mess it up more.

Yea after I got mind-f***ed I did press the edge a lot to be sure.(we humans ...) But now am controlling myself to not press the edge and use it normally.

Exactly why am thinking hard if I should get mine replaced. Another reason being I'll be leaving UAE(got the phone here) for good in a week and if by chance I do get a defective unit I'll waste a lot of time.
I'm not gonna play around with the edge anymore haha.

Yes you're right a lot of electronics and gadgets have creaking parts. Mostly the ones made outa plastic though. Does your HOX creak too?

my first flexed bad (soft one pressure, loose) on the left side, although i loved it so much because it had the much more dense yellowish sharp screen
second hox had a bad coating and slight flex on the left side, also hot pixels
third HOX my current is perfect, the screen is rigid on all sides expecially left and right, but it creaks if its around 50degree hot on two out of the four corners, very very slight creaks and only happens if it test it intentionally, it has the acer white screen with visible pixel grid, so the first hox screen i miss so much
im saying don't replace for a little reason bro it will be a bumpy ride, if the screen is loose then ok, you can see it by testing for light bleed in a dark room or if its physically moving

I think my screen is perfect. I can't figure how you're suggesting I test it, but pressing along the edges with slight pressure doesn't cause any change in the screen. The pixels are all good and no flickering. I think its a yellowish screen and not the bluish one.
How do you find out what LCD brand is on your HOX?

there is a guide somewhere on how to check the LCD

Hmm I don't think I'll get it changed, I love it too much . Just have to get used to the occasional/random creak/click sounds from the device.
