Hey! My iPhone 4 Multi-Touch display Freezes Up???

Lately the Multi-Touch screen freezes up! Won't respond to my touch! Even when I tried to power it down, I'm unable to get the "arrow bar" to respond!!! It wasn't until a few tries pressing both the "power down button & reset button" that I was I was finally able to turn it off & power it up to finally get the screen to respond to my touch.
Is this a hardware issue or software??

Probally your handset, no one else that I know of has had the issue.

Multi-touch display is not functioning as normal

multi-touch display is not functioning as normal on the right half of the screen....

Hi James,
Thx for the quick reply...
I have already tried most of these troubleshooting steps but no go....
Also, when you tap or use only the right half of the screen, the touch display is inconsistent and makes a wierd sound [ like a hollow tub or something ] and it's not a cosmetic issue...
----Apple store / Authorized Service Center is still working on this ongoing issue with no results and still not confirming for the iphone replacement...Thnx..

Iphone 5 multi touch spoiled

Hi,
I recently updated my iphone 5 (approx 2 yrs old) from ios 7.1 to 7.1.1
Post this, the iphone display is going nuts. Most of the time it will not recognise the touch.
I have to lock and unlock the phone to get the touch work (still it will work only for 4-5 seconds and becomes unresponsive again).
I restored but to no help. I contacted the apple service centre and they told me that due to the update multi touch is spoiled.
They checked that it is not due to any liquid spillage or any other thing.
But they cannot help me as the warranty is expired and quoting huge amount to get the phone replaced.
Anybody else faced similar issue after softwares update?
If yes, how can I get this fixed
TIA

Hi pogster,
I got the above reply from apple authorized service center. They after checking the phone told that the update might have failed to recognize the display component and hence have this issue.
I again contacted apple support over chat and the guy confirmed the update has failed to recognize as the particular display component has hardware issue.
Apple support -->
"it’s indicating that there was an issue with the component with the touch screen not accepting the update. There can be a number of different causes. In this scenario it’s just indicating an internal communication issue."
Due to the hardware issue, that’s why we’re experiencing this problem. The issue isn’t due to the update, that would indicate a software issue which during a restore and setup as new would be resovled.
It wasn’t caused due to the update. It’s indicating that issue was already there with that component. The update, confirmed the issue with the hardware component."
He told me to get it replaced by paying an out of warranty price.
But I dont understand that if there was an hardware issue accepting updates, then why the phone got updated to next software version. It was working properly with the previous version.

IPhone and multi-touch

I assume everyone has been following the iPhone announcement
today:
http://www.engadget.com/2007/01/09/live-from-macworld-2007-steve-jobs-keynote/
I also am assuming that since it runs OS X, we can download
Flash 8 & 9
desktops apps (and even created standalone). Correct?
But what we really need is to be able to tap into the
multi-touch interface:
1. stretching and zooming photography
2. zooming and exploring maps
3. getting all one's fingers into intereractive paint and
draw tools, etc.
I used a multi-touch at SIGGRAPH Boston 2006
http://cs.nyu.edu/~jhan/ftirtouch/
) and it is very very cool.
Is Adobe partnering with Apple to produce special fscommands
for a iPhone
centric version of Flash?
[I have a huge load of apps and ideas, as well as a startup
company if Adobe
will pursue this!]
Dr. Yechezkal Gutfreund - Adobe ACE for Mobile Devices

Mark, right on.
It would be a logical platform for Flash given some of its
core
philosophy in its design. However, the details about OSX and
Safari
support are still far too vague as you point out below.
It wouldn't surprise me in the least, if they modified "OSX"
to "OSX
Mobile" as they move closer to deployment ... but, perhaps
all they need
is a kernel to technically call it "OSX"? Not sure.
Speaking of which ... I think we are forgetting too, how
stable Symbian
and other mobile device centric OSes and platforms are. How
long have
they been working at "OSX for the iPhone", one year? perhaps
two? Looks
impressive in the demo ... but it's only a demo. How much was
"off the
cuff" and not stagged, we have no way of knowing ...
My point being, a SBOD ("spinning ball of death") on a mobile
device
might equate to a death sentence (well, for a first time user
iPhone
experiences), *even* with all the great UI and features
they've added.
Here's hoping they do some exhaustive device and field
testing before
rollout later this year ... in order to limi the amount of
software
and/or firmware updates they have to do later on (we've seen
that on the
initial IPods to be sure) ...
All in all, I'm hopeful, given Apple's track record with
previous
desktop versions of OSX and delivering stable releases (well
more
reliable and complete than say, Microsoft), they'll have
something worth
putting on the iPhone come end of year. Time will tell.

IPhone SDK Multi-Touch Bug?

Hi,
I'm trying to handle multi-touch events and this is the bug I'm seeing ( using SDK beta 4 ):
The first touch I make has a valid position ( using locationInView instance method ). However, any touches made while the first touch is being held down have invalid positions ( 0,0 ). Here's my code:
// Handle touch events
- (void)touchesChangedWithEvent:(UIEvent*)event
printf( "* TOUCHES CHANGED EVENT!\n" );
NSSet *touches = [event allTouches];
for( UITouch *touch in touches )
// Grab the location of the touch
CGPoint touchPos = [touch locationInView:self];
// Touch began
if( touch.phase == UITouchPhaseBegan )
printf( "**** TOUCH BEGAN AT ( %f, %f )\n", touchPos.x, touchPos.y );
iRKInputSetNewTouch();
iRKInputSetPos( touchPos.x, touchPos.y );
// Touch moved
else if( touch.phase == UITouchPhaseMoved )
printf( "**** TOUCH MOVED AT ( %f, %f )\n", touchPos.x, touchPos.y );
iRKInputSetPos( touchPos.x, touchPos.y );
// Touch stationary
else if( touch.phase == UITouchPhaseStationary )
printf( "**** TOUCH STATIONARY AT ( %f, %f )\n", touchPos.x, touchPos.y );
iRKInputSetPos( touchPos.x, touchPos.y );
// Touch ended
else if( touch.phase == UITouchPhaseEnded )
printf( "**** TOUCH ENDED AT ( %f, %f )\n", touchPos.x, touchPos.y );
iRKInputClearTouch();
iRKInputResetPos();
Anyone else seeing this? Or am I doing something wrong?
Also, any help on displaying source code would be appreciated too
Thanks!
- Bryan

So, with the following multiple event code I seem to be getting an even worse problem: Multiple touches aren't even triggering the events and my first touch is always the only UITouch in the set ( even when I have two or three fingers touching the screen ). This is on the device using SDK beta 4.
// Handles the start of a touch
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
printf( "* TOUCH BEGAN
for( UITouch *touch in touches )
// Grab the location of the touch
CGPoint touchPos = [touch locationInView:self];
// Touch began
//if( touch.phase == UITouchPhaseBegan )
printf( "**** TOUCH BEGAN AT ( %f, %f )
", touchPos.x, touchPos.y );
iRKInputSetNewTouch();
iRKInputSetPos( touchPos.x, touchPos.y );
// Handles the continuation of a touch.
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
printf( "* TOUCH MOVED
for( UITouch *touch in touches )
// Grab the location of the touch
CGPoint touchPos = [touch locationInView:self];
// Touch moved
//if( touch.phase == UITouchPhaseMoved )
printf( "**** TOUCH MOVED AT ( %f, %f )
", touchPos.x, touchPos.y );
iRKInputSetPos( touchPos.x, touchPos.y );
// Handles the end of a touch event.
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
printf( "* TOUCH ENDED
for( UITouch *touch in touches )
// Grab the location of the touch
CGPoint touchPos = [touch locationInView:self];
// Touch ended
//if( touch.phase == UITouchPhaseEnded )
printf( "**** TOUCH ENDED AT ( %f, %f )
", touchPos.x, touchPos.y );
iRKInputClearTouch();
iRKInputResetPos();
So when this is run and press the screen I get correct messages output to the console telling me a touch began / moved with the correct position. However, when I keep that press held and press somewhere else I get no other messages. When I move the first touch ( while keeping both touches held to the screen ) it gives me correct messages again but yet it's the only UITouch object in "touches".
Anyone else seeing problems with this?
Any help would be great! Thanks!

W510 Multi Touch Display Driver NOT installing properly on a fresh Windows 7 Professional Image.

Hello everyone, this is my first post here and I will make it as short as possible. First, thanks in advance for taking the time to read this and helping me out in any way possible.
I have a fairly new W510 machine with a crucial 256GB SSD in it. My SSD crapped out (luckily I had a back up) crucial sent me a new one and I just imaged the new drive a couple of days ago with my backup (The backup is made from the original Lenovo install). However during the imaging some Windows components were damaged for some reason (perhaps due to the previous drive crapping out). The only fix was to go ahead and use the retail windows 7 Pro DVD to "repair" the windows installation by clicking the "upgrade" button after inserting the disk. --As Microsoft suggested this to fix an existing win 7 installation. After I did that EVERYTHING worked flawlessly! I was really happy with the machine, it booted in 30 seconds and what not. However, the multi touch driver for my W510 screen will not stick ... no matter how many times I install it, as soon as I "log out" of the machine, the driver rolls back to a normal pointing device and multi touch is disabled and my on-screen keyboard vanishes. It is the weirdest thing I've ever seen. Here is exactly what I'm doing.
1 - Log into my Admin user account
2 - Install this: http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-74908
3 - Multi Touch works great!
4 - Logoff or Lock machine or put it to sleep.
5 - Log back in my admin user account
6 - Touch screen works but all multi touch features are now disabled (As in no pan/scroll no pinch to zoom no nothing) the touch screen simply works as a simple mouse (point and click).
7 - Install the driver again (mentioned in step 2) --Again everything works great.
8 - Repeated 3 to 7 ... Forever …
I tried completely removing the driver and re-installing it from scratch, I tried getting the raw ISD-V4 (W510's screen driver) directly from Wacom (works too) but again the minute I Logoff or lock that machine, the driver just rolls back or goes back to a normal pointing device. It is really weird that this is happening. The touch screen always worked well and I never had any problems with it. Also in device manager nothing has changed, it seems that everything is in good shape there.
My W510 specs:
- Intel Core i7 Extreme X920
- 16.0 GB DDR3 RAM (G-Skill)
- 256 GB Crucial M4 SSD
- No GOBI 2000 Card.
- Intel WiMax Installed and Enabled.
- CD-ROM Drive in UltraBay
- Cam / Fingerprint Reader / Color Sensor / Smartcard Reader / Expansion all installed
- Windows 7 Professional SP1
It seems that Windows is somehow defaulting to a different "driver" that is over-riding the multi-touch driver I download and install when I log off. Do I need to install the driver outside my user account? Or is there a method to erase the default drivers or something? I am trying to avoid re-imaging this machine from scratch using the provided Lenovo Windows Partition. I just have too much development software on it, some of which will take me forever to re-install and re-configure.
Any help is appreciated.
Thanks!
Al.

Hi Patje.
From the OS perspective, while we are not prioritizing multi-touch capability across multiple monitors, there are some scenarios that should work just fine right now:
One multi-touch monitor and one regular monitorconfigured together.
Two multi-touch monitors (but not with simultaneous input)
Unfortunately, at this time you would need to use your mouse to drag from one monitor across to another. If you had two multi-touch monitors you could drag an object so that it straddles both monitors and then pick it up again on the other monitor. Unfortunately, there's just no way to bridge that physical space between the monitors in a fluid fashion at this time.
Thanks so much for the question. It's interesting to think about this.
Sincerely,
Eliot - MSFT

How many Multi-Touch points can an iPhone/iPod touch have at the same time?

How many Multi-Touch points can an iPhone/iPod touch/iPad have at the same time?
I am curious as IIRC (but forgot where the article is on the Internet),
if a touch surface is wanted to be able to detect more than 1 touch point at the same time,
then that touch surface needs adding 1 more conductive(?) layer.
(e.g. 2 points -> 2 layers, and so on)
So I wonder how many these layers are on the iPhone / iPod touch / iPad or even the trackpad on every MacBook (Pro).
(correct me if I'm wrong)
Just curious, thanks in advance!

I believe it can only support 2. This article explains how the touch screen works but doesn't explicitly say how many points is supports.

My screen freezes after a few seconds on my iphone 5c and the display fades slightly so you can see faint lines in the background. I'm not sure whether this is easily fixable or a major problem. Have reset the device, but this has worked. Any ideas?

TS4443 Unable to sync multi touch ibooks from iPad to iphone

Hi,
Purchased and downloaded a multi touch book from ibooks to iPad air, but it does not sync to iPhone.
Can it? Should it be able to?
Thanks

Does the book's description in the store say that it's compatible with iPhones ? If it is then what happens when you try to sync it via your computer's iTunes ? Have you tried redownloading it directly on your phone via the Purchased tab in the ibookstore in the iBooks app ?

Multi-touch too sensitive iPhone 5

I have been experiencing a very annoying problem. I have changed my iPhone 5 twice already because of this.
When I try to write something, it keeps closing my keyboard, pressing buttons without me touching it. It closes the app I am using, or decides by itself to add a picture to my conversation.
It looks like the screen is way too sensitve and that it multi-touches every button available, to a point that I cant even have a proper txt msg conversation anymore. It has a life of its own.
Any suggestions of how I can solve this problem?

Multi-Touch Gesturing on iPhone 4

Hi guys, i did the whole XCode via MacBook Pro thing with my iPad 2, that gave me Multi-Touch Gesturing which is sooo sweet....4-5 finger swipe accross apps, 4-5 finger swipe up to show the mult-tasking pane; 4-5 finger pinch-close to get to the home screen........What can beat that??????
Issue is , I tried to do the same steps (via Xcode on my MacBook) for my iPhone but it doesnt work on my iPhone..the feature doesnt exist in settings.... , maybe they just built it for iPad?
Does anyone know?

Agreed. I just assumed it would be functional on my fancy new 4s, I was shocked that it was missing! I stared at the settings panel for way too long, then busted out the iPad and compared settings panels, indeed, the toggle is completely absent on the iPhone!
A three finger up/down for task bar, left/right for app switch, and pinch for home would be awesome.

Multi-touch iBook on an iPhone?

My company has recently submitted a Multi-touch iBook and received approval. Some of our customers have been confused why they can not open it on their iPhone. This is not something I expected, but now that phones with bigger screens are available, I supposed these iBooks are more usable. Is this a feature that Apple will introduce?
Thanks!

We are fellow users here on these forums, we won't know what Apple might be planning until if/when they announce something, but at the moment they can only be read on iPads - you can't open any ibooks created in iBooks Author on iPhones.

Multi touch screen fix

Multi touch screen needs calibrated on iPhone 4S. Anyone know how this is done.

No such thing as calibrating your display. If restoring your phone as a NEW device (not using backup at all) doesn't resolve your issue, you'll need to take your phone in to Apple for evaluation.

My iPod Touch is freezing and rebooting itself.

Hi.
Here's the story:
My iPod was recently working yesterday. I left it on the wall charger for a while, and later I come back to find my iPod frozen, out of nowhere. For another while, it freezes and starts to reboot itself. I done all I can. I watched videos on how to unfreeze it and etc, and I tried restoring it, and doing about everything I can to recover this iPod, it doesn't work. So I turned it off, and let it settle overnight. This morning, I turn it on, and it restored, everything was working fine, until when I go to my Messages app, it freezes once again, and now it is doing the same thing, but this time it repeats to the home screen, freezes, and reboots again. I tried calling for support and they said my warranty is expired.
I own an iPod Touch 4G, 8GB, for about 6 months.
To be specific: It always goes to the Apple logo and then the loading circle then shuts off, then does it again. Before this problem about a day before this happened, I accidentally put a little water on it and wiped it off while I was working on chores. (Sorry, I often have it next to me a lot.) Plus, I did have a lot of data on it but it didn't seem much of a problem.
Please, if anyone can help, tell me what is the reason behind this problem, and at least if you can try to solve this for me. I will try going to a local Apple store later on if this problem keeps going. But for right now, I need this help. Thank you all.
Bye.

- Have yu tried letting the battery fully draining and then charging and trying to retore the iPod to factory defaults/new iPod?
- Try placing it is recovery mode and then DFU mode and then restoring if necessary.
