Hello.
I'm dealing with this PDA that's from a friend. He told me that it's very slow (it had WM5). I update with some homemade ROMs to see what happens and the result has been really annoying:
Operations are sluggish. Even the screen aligning process is horribly sluggish. Everything is slow as hell. The screen seems to miss some taps, too.
What's the problem? Somebody with this problem?
EDIT: I have seen that the touch screen is failing! The taps are hold when the stylus is not on the screen. Could it be a failing touch screen?
Well, later to have checked and tested intensively I've come to the conclusion that this lack of responsiveness is produced due to a hardware error. The touch screen is failing and the CPU processes a large a mount of taps without actually touching it, so it's too busy to process any other task properly.
I hope this help to anyone having the same problem.
Thank
Issue with touch screen ?
Concerning your sluggish PDA, is there a plastic film to protect the screen ?
Some plastic films may cause very weird behaviours as the screen could be fooled and act as if some point on it would be touched. It's all the more true when the film is in contact with both the screen and its frame, due to bad alignment when sticking it.
I had a similar issue with a Tomtom One (1st issue) and was about to send the device back to warranty... everything was solved when removing the protective film !
It's rather obvious with first generation films that were really thicker than new ones.
Hope I was of help...
if you cant fix it and are going to get rid of it i will take it off you. mines motherboard is scrambled, but the screen is fine.
thats if your getting rid of it.
Ever since I got my brand new HTC Touch Pro I noticed the screen to be way less sensitive than my girlfriend's iPhone.
For example in the Contacts app, when I use my finger to scroll down or up I find myself many times opening a contact rather than the screen scrolled down or up. Same goes for many other presses on the screen with the finger. I find myself using much more force than I naturally would use with an iPhone
I wonder if my unit is faulty requirming more pressure to the screen or maybe that just the way it should be by deisgn? I assume only users who used both iPhone and Touch Pro could answer that. I don't know anybody with Diamond or Touch pro so I have no way of checking it other than asking you guys.
Thanks
Iphone and Touch Pro use different types of touch screen.
We have Capasitive screen on iPhone which doesn't require pressure, just a touch.
And we have touch-resistive screens on most of Windows Mobile (inc. Touch Pro) which are less sensitive than iPhone...
Here is a link that might help: http://www.rycom.com.au/capvsres.htm
by the nature of the technology involved to sense your touch, the pro is less sensitive than the iphone.
the iphone uses a capacitive touchscreen which senses the electrical signal around your finger whereas the tp uses a resistive touchscreen which senses where your finger presses the screen in.
resistive screens are designed for sytli, and the "gestures" and flick scrolling implemented on many htc devices are a kind of fudged system to imitate gestures on the iphone. i know on my wizard i could adjust the touch scrolling sensitivity through schaps advanced configuration tool, but i'm not sure if you can do that with the touch pro. its all about how much force/speed you use on the TP.
i know you can get used to it, and it will function properly, but it is definitely different from the iphone. good luck!
Thanks guys. Both of your replies are most helpful. I began to fear that my unit had a fault in it. Seems to make sense that is how it works after I understand it. I most appreciate the responses. Thanks.

You will get better results using software designed from the ground up to be finger-friendly e.g. touchflo3d works well with only light pressure, and for contacts pocketcm also scrolls with only light pressure.

On the plus side, the Touch pro(and all other non-capacitance screens) are less picky. I noticed that if you use fingernails on an iPhone it will ignore you. you have to touch with your finger. Our screen will respond to anything that touches it...pen, fingernail, rock. There are +/- s to both. Just have to get used to the change.
yeah pocketcm is great for scrolling also there is pointui if you dont like touchflo that is a free app that redoes the interface all scrolling too
and i usually use my fingernail for most stuff instead of my finger

I used a metal key depth gauge, and though it felt smooth, it put a nice scratch on the screen. It was a new replacement, and I hadn't got the screen protector yet. Good thing I'm not an anal OCD-head
Stylus' (Styli?) seem to be out of fashion at the moment, but they are far more accurate for doing work in spreadsheets and other applications with lots of data on the screen.

agreed, i have no problem being a "geek" and whipping out the stylus, especially when it magnetically snaps back in
is there a way of using stylus in capacitive screens?
Our fingers eletricity shouldnt be conducted through the stylus metal and reach the screen? Why it doesnt work?
is it true that HTC G1 is capacitive?
G1 is capacitive
Its not so much conducting electricity, more of eminating an electric field. i know there are certain "silver fingered" gloves that let you use the ipod/iphone with gloves on, and i would guess that there are capacitive styli as well, but i havent gone searching one out.

I have been whipping it out in public since the Palm 3.
I sometimes feel that Windows Mobile doesn't make the best use of Stylus input compared to Palm OS (tap a time to create a new appointment for example) but both zip along compared to finger presses on the iPhone for most serious work.

it's due to the resistive touchscreen. it's less sensitive than the capacitive screen in the iphone.
but the touch pro screen is actually less sensitive than other htc resistive touchscreens such as the kaiser. it's much less sensitive e.g. near the edges of the screen because of the bezel underneath, you need to press harder at the edges to get it to register a touch.
My wife is weird. If she is around electronic things it mostly goes wrong. This is very annoying with touch screens. What can be the cause that a capacitive touch screen of a device which reacts perfectly to me hardly does to her? And more important, how to solve it? Wear wool?
Since I have had the OPO I have had intermittent issues with the touchscreen requiring reboot to solve. Since upgrading to CM12 the issues seem to have largely subsided but last night I dropped the handset from about 18 inches off the ground. The top left corner of the screen shows a bit of cracking on the glass and now I notice that there is an area in about 1/3 of the touchscreen that is unresponsive. The lower and upper parts of the screen work but now there are some apps and functions I cannot use with the touchscreen and I notice I have having a lot of trouble with the pattern unlock screen as well.
My question is whether the entire digitizer screen will need to be replaced or if there is a possibility that the ribbon connectors or some other connection is possibly causing this issue. I have attached here a pic of the physical damage and a screencast of multitouch test that I ran to demonstrate the area affected. It seems to start around y0=400 and continue to y0=1100 or so which is quite frustrating. In the video I am just running my finger up and down the screen and also across diagonally to demonstrate the problem areas.
Apparently I cannot post Youtube links since I am a new member but the video is on there posted under
"OPO touch screen issues after drop"
Anyone with insight would be much appreciated as I certainly would not like to have to tear this phone down and replace the screen assembly.
I doubt it's a ribbon cable, otherwise your whole screen would be dodgy. I think you need a new digitizer + LCD.
Here's a link for the video you are trying to link to.

Hope someone here has some good news for you.
Hello, guys.
Recently, I dropped my M2 on the street, resulting in cracked touchscreen and lcd. Replaced both the touch and the lcd, everything seemed normal until I noticed that the middle part of the touch (a line going from the left to the right, around 1cm height) doesn't work, it just doesn't respond. Later, I got another new touchscreen and same story - same part of the screen doesn't work.
Maybe we have some kind of defect touch screens here in Bulgarian stores? Though I bought the two touches from two seperate stores. Or it's possible that it's something with the lcd? Even though it works normally, no strange behavior, no black spots, scratches or anything. Or could it be a software problem? Using Android 5.0.
Thanks in advance.
More likely to be motherboard problem if it's the same with 2 different screens being installed
Thanks for your answer.
One thing I forgot to mention - when testing the screen in Sony's Sketch app or in the service menu, if I run my finger from the top to the bottom, or the opposite way quickly, sometimes, the lines my finger makes don't get cut, i.e. it's like the screen is functioning properly, with no dead spots. What does this mean?
According to Sony support, it could be a compatibility issue between the phone/touchscreen/LCD, what do you think?
