My iphone 4s freezes (hangs)

My iphone 4s freezes (hangs) during calls with the time still counting and takes some minutes to restore or I turn it off.

Hi Maor_k007,
This article has some steps you can try for camera app issues:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/ts2802
Camera
Camera isn't functioning
If the screen shows a closed lens or black image, force quit the Camera app.
If you do not see the Camera app on the Home screen, try searching for it in Spotlight. If the camera does not show up in the search, check to make sure that Restrictions are not turned on by tappingSettings > General > Restrictions.
Ensure the camera lens is clean and free from any obstructions. Use a microfiber polishing cloth to clean the lens.
Third-party cases can interfere with the autofocus/exposure feature and the flash (iPhone 4 only); try removing the case if you have image-quality issues with photos.
Try turning iPhone off and then back on.
Tap to focus the camera on the subject. The image may pulse or briefly go in and out of focus as it adjusts.
Try to remain steady while focusing:
Still images: Remain steady while taking the picture. If you move too far in any direction, the camera automatically refocuses to the center. Note: If you take a picture with iPhone turned sideways, it is automatically saved in landscape orientation.
Video: Adjust focus before you begin recording. After recording begins, you cannot readjust focus until you stop recording. Exiting the Camera application while recording will stop recording and will save the video to the Camera Roll. Note: Video-recording features are not available on original iPhone or iPhone 3G.
If your iPhone has a front and rear camera, try switching between them to verify if the issue persists on both.
Cheers,
- Ari

IPhone freezes/hangs after sending iMessage

Anyone else having this problem or know a fix? Almost every time I send an iMessage my Iphone 4 will hang/freeze for almost 30 seconds before I can do anything else. If I send a regular txt it's fine. Anyone know of a fix for this? It's becoming very annoying

I'm suffering the same thing. Seems to happen during the day (as opposed to the night). This was happening before and I read somewhere it was traced to the use of the Mac OX Messages beta app that Apple released before Mountain Lion. I uninstalled that beta and things seemed to get better. Now I'm running ML on my Mac and this issue is back. Is there an issue with the Mac app logged into iMessage and the iPhone too?
Very curious whether this has a fix somewhere.
Thanks for posting.

Iphone keeps freezing when I am going to end a call.

My Iphone sometimes freezes when I make phone calls on it. This only happens at the end of the phone call but it is really frustrating because I cannot hang up the call. I called my service provider and they told me it was because of the clear screen protecter I put on my phone. Could this be possible or are they just making this up to get me to quit complaining?

Hello Jennings Castle,
It seems your iPhone is slowing down and not responding frequently. To rectify this issue you may want to consider performing a restore on the device, and then restoring your data from a backup via iCloud or iTunes.
If the issue persists after restoring your backup, you would then want to consider restoring the device and setting it up as new. Below I have linked to article which offers guidance on both of these restore methods:

Are you syncing your contacts with something. If so, they are not lost.

iPhone 4 freezes up and changes screens, drops calls, won't hang up

HI!!!
I have an Iphone 4 for 3 years now on and when now I turned on the screen freeze. It doesn't have the screen cracked and it doesn't have any damages of any kind. I did the reset with the home and sleep button and doesn't work. I did the restore process with Itunes and still freeze. I don't find any other different solution to this problem. Is there any other different process that I can do? PLEASE let me know.

Photoshop CC and Photoshop 6 Freezing/Hanging

Ok so I have read many threads on this topic and none have been an answer to my problem.
This happens on MacPro with 2 x 2.4Ghz Quad-Core Intel Xeon with 24GB of 1066 MHZ DDR3 Ram and an 512Gig SSD, freshly formatted and Photoshop CC loaded and running without any other apps. I also use a Wacom Intuos 5 touch M with driver 6.3.6w3. I also have 3 x iMac 27" top current spec SSD and 32Gig Ram and wacom tablets, Intuos 3 and 4.
This problem occurs normally when selecting a brush to work on a layer mask (size of brush not relevant), once the freeze occurs, the cursor can still be moved around however a brush mark isn't registered. To exit this freezed state it is necessary to click on another application (preferably the finder) and return to photoshop in order to snap it back in to action. Sometimes this problem has to be repeated 2 or 3 times. It doesn't appear to make any difference what size the image is. Often if I open up a flat jpg, grab the clone stamp tool and start to work, there are no marks registered. Once the freeze/hang is exited often the previous brush marks appear altogether. This seems to happen all too regularly, maybe every 15 mins or so, but never consistently spaced out
I have tried all of the things below to solve it:-
1. No 3rd party plug ins running.
2. Ample scratch disk space on second internal Sata drive (500Gb)
3. GPU settings changed to Basic
4. I don't have a third button on my pen to turn off
5. Wiped and re-installed OS X 10.8.4, reinstalled photoshop
6. Made history states greater and less
7. Turned Autosave off and save in background
8. Regenerated new Preferences
I have looked into Activity viewer when this happens and nothing seems obviously wrong. Please help as I thought is was a bug in CS6 so upgrading to CC was looking very attractive until the same problem happens here too.
HELP! HELP! HELP!

Curt, I have a ATI Radeon HD 5770 1024 MB in the Mac Pro, the iMac have NVIDIA GeForce GTS 680MX 2048Mb.
Why would it happen on all of these machines though if they have different video cards?
Very Puzzled!

How can I stop my iPhone from freezing?

My friends iPhone keeps freezing, is there a way of preventing this form happening?

If a reset doesn't help, try these steps as needed, as described in the User Guide, Appendix B:
1. Settings > General > Reset > Reset All Settings
2. Restore phone in iTunes using a backup
3. Restore phone in iTunes as new, without using a backup.
http://manuals.info.apple.com/en_US/iphone_user_guide.pdf
If restoring as new doesn't help, there is a hardware problem in the phone.

Windows 7 freezes / hangs when playing video or audio on any media player

I've had this issue since installing Windows 7 (32 bit) over 2 months ago and have been actively seeking a fix for the majority of those two months. In windows XP pro (32 bit), I had no issues whatsoever. The problem manifests itself as a complete hang of all system functions and inability to interact with my computer aside from moving the pointer around.
This only occurs when I am playing some sort of media (mp3, avi, mp4, mkv, etc) on any media player that I had installed at the current time of testing (WMP12, VLC, Realplayer). The initial response is a hang of the system which then can become a freeze if I click around too much during the hang. After approximately 3-5 minutes the problem is alleviated and the system plays catchup with the video/audio sync.
Below is a complete rundown on my system and fixes floating from other threads that I have attempted.
My System Spec:
Windows: Windows 7 Ultimate (32 Bit) Version 6.1 Build 7600
Motherboard: Gigabyte Ds4-X48 Crossfire Ready
GPU: ATI Radeon HD 4870 512MB 256Bit DDR5
CPU: E8500 Wolfdale (3.16) Core2Duo
Ram: 4GB ( 2x 2GB OCZ Reapers @ PC8500 1066MHZ )
PSU: 600W OCZ GameXStream
HDD - Primary - 1.5TB Seagate
HDD - STORAGE - 1.5TB Seagate + 500GB Western Digital
Audio - Integrated Realtek
Drive Bays: SATA Combo Drive (Samsung) + IDE Lightscribe DVD-MultiRecorder RW
As you can see, my system is more than capable of running Windows 7 and probably just as qualified to captain a space shuttle.
Things I have tried to no avail
- Changing the Power Plan
- Adjusting the overclock of my GPU to factory defaults
- disabling Media Player Network Sharing in services.msc
- Only having WMP12 installed
- Shark007 Codec Pack
-Not having Shark007 Codec Pack
- Undergrading WMP12 to WMP11
- CLEAN BOOT - Freezes/hangs still occured regardless.
- Registry optimization and cleaning
- Playing video after fresh install still causes freezes
- SQMClient/MachineThrottling IS NOT THERE TO BE DISABLED OR DELETED
- Adjusting RAM timing,frequency and voltage in BIOS
- Use Display driver provided by Windows Update for ATI Radeon HD 4870
- Tested several other Catalyst and Display drivers
- Updated Chipset , Audio Driver, Network Driver
- Clean installed 4+ times ( I clean installed inbetween all of the previous attempts listed above)
- Uninstalling programs such as AIM, MSN Messenger, Adobe products, Daemon Tools Lite, Adobe Flash Player 10 ActiveX
-My computer is not eligible for the Intel Matrix Storage update
-Disabling aero
I am now starting to suspect maybe Company of Heroes may be an issue as it is Divx endorsed.
I froze once while typing this up due to wmp12 playing a mp4 music video in the background.
Can anyone recommend a good skin and theme that will make Windows XP look like 7? I'm starting to think that it's my only solution.

Hi,
Thank you for your posting.
As for this system freezing issue, we generally need to analyze the performance monitor logs and memory dump files to locate the root cause. Unfortunately, debugging is beyond what we can do in the forum because of the nature of forum support. A support call to our product service team is needed for the debugging service. I'd like to recommend that you contact Microsoft Customer Support Service (CSS) for assistance so that this problem can be resolved efficiently. To obtain the phone numbers for specific technology request please take a look at the web site listed below:
http://support.microsoft.com/default.aspx?scid=fh;EN-US;PHONENUMBERS
If you are outside the US please see http://support.microsoft.com for regional support phone numbers.
Having said that, I'd still like to provide the following general troubleshooting steps to see if we can eliminate this problem:
Note: Please perform a complete system backup first. If any unexpected issue occurs, we can quickly restore the system to the current status.
1.    Scan your system to make sure that the system is virus free. Temporarily disable your anti-virus software to see if this problem is gone.
2.    If you have recently installed any software, hardware or drivers, please remove them.
3.    Run Process Explorer to check which processes are using a lot of memories or cause high CPU utilization:
Process Explorer
4.    If the process is a service, you can use these steps to find out what applications are using most of the CPU: Open Task Manager, click on the Processes tab, look for the process that is using the CPU and note its PID (Process ID). Note that you may need to go to the View/Select Columns menu and make sure that PID (Process Identifier) is checked.
Once you have the PID run the following from a command prompt:
tasklist /svc
This should give you the application associated with the PID you identified in the previous step.
However, if the issue still persists, please contact Microsoft Customer Support Service (CSS) for further troubleshooting. I hope the problem will be resolved soon. Thanks!

LabVIEW 6.1 Freeze / Hang – Related to User Interaction / Potentially File I/O

Hi Everyone
As you can see by the title, we are using an archaic version of LabVIEW. This will not change, as the system has been running since 6.1 was new, and it is our philosophy not to touch a running system.
The thing is that it isn’t a running system anymore. Or should I say it’s never been perfect, only that we didn’t notice. Anyhow… Here comes what this is about:
We use LV in a jet engine test environment. Now, a normal engine test would take something like an hour or maybe a maximum of two, depending on the applicable test procedures. This time frame used to cover the majority of tests and we had no problems whatsoever. Recently though, we had an accumulation of engines that caused problems and therefore the tests started taking longer and longer, up to four or even five hours. And that is when the problems started…
LabVIEW would run just like it should, until after a long time it would suddenly freeze / hang upon user interaction. It looks like this could be related to some file i/o, like writing test results to an excel file or alike (“Save”), but I cannot rule out 100% that this impression is wrong. The data, however, will never be saved to the file in cases of a freeze / hang.
To test it and see what happens, we had let the application run over night and write some data and a time stamp to a text file, so we could see if and when it would hang. Nothing happened, obviously because there was no user interaction.
It may be handy to know that we are running LV on a Windows XP SP3, 32Bit system. The O/S doesn’t hang / freeze and everything else carries on working just like it should, it’s only the LabVIEW application as such that hangs (all of it, not individual *.vi’s or loops). Normally, after several minutes the application is back, but TCP and *.xls ActiveX references (refnum, in a global variable) are closed, and need to be re-established manually.
I know this information is very vague and you may need more input to be able to help. Yet it is a starting point.
Thanks for feedback!

Really hard to even begin to diagnose the problem with this data. You mentioned that your wrote to a text file with a time stamp, so I'm assuming from this that the program can be modified (just not upgraded to a newer version)? If so there is a diagnostice utility in the Windows kernel32.dll that might help, if used properly it shows "stuff" going on in your code and in the Windows environment. What we do here is create a little sub-vi that will write a string to the Windows debug "file", and salt these throughout our code, showing when commands are issued, threads are shut-down, etc. Using a free download utility from MicroSoft called dbgVIEW we open a monitoring window behind our code and watch what is happening. It is particularly useful if you are running your application as a exe as it can give you a view into the inner workings without the overhead of writing to a file, etc.

My iPhone is freezing all the time

Ever since I upgraded to the 2.0 software my iPhone has been freezing upwards of 10 times a day... i only have 5 apps, and I still have 2GB of space on my 8GB
Is there anything I can do to stop my iPhone from freezing... also, when i try to reset it, the reset only sometimes works.

Try to restore it... I'm hating this iOS 5.1, everything was working much better before it was released. I shouldn't have upgraded...

Fixed my SL freezes, hanging, beachball

After migrating from Leopard to Snow Leopard (10.6.2) about a month ago, I experienced a constant issue with hanging applications, sporadic freezes with a variety of applications.
I have gone through all the suggestions posted wrt to this issue and for me the following fix worked (so far...) rather perfect. My systems now runs as stable as it did using Leopard. Reinstalling, PRAMMING, VRAMMING, CleanUps, DiskUtility check, S.M.A.R.T. status checks & eventually just using TimeMachine restore did not solve my freeze/hanging/beachball issue
_My solution_: go to ~/Library/Internet Plug-Ins/
and put all the plugins you see there into a custom folder (I named mine SwitchedOff). Now move all the plugins to that folder and reboot. Well: now your browsers are decapitated, so I moved
Flash Player.plugin
flashplayer.xpt &
Silverlight.plugin
back into ~/Library/Internet Plug-Ins/
and restarted the browsers. (now enabling flash & silverlight video options)
Result: no more sporadic freezes, hangs, 30-60 secs. beachball phenomena and basically a stable steady OS I was used too.
FYI: I have not tested moving back the other Plugins into my ~/Library/Internet Plug-Ins/SwitchedOff folder. They now contain:
DivXBrowserPlugin.plugin
Flip4Mac WMV Plugin.plugin
Flip4Mac WMV Plugin.webplugin
Googletalkbrowser.plugin
iPhotoPhotocast.plugin
JavaPluginCocoa.bundle (an alias)
NP-PPC-Dir-Shockwave
npdivx.xpt
nsIQTScriptablePlugin.xpt
Quartz Composer.webplugin
QuickTime Plugin.plugin
XStandard.plugin
I will do some testing if re-adding these plugins recreate the freezes etc. but for now this solution works for me and will enjoy a freeze-less OS for now.

You're correct. BTW, these are installed on my SL machines and have never caused any issues for a year and a half (beta-tested SL):
DirectorShockwave.plugin
DivXBrowserPlugin.plugin
DRM Plugin.bundle
Flash Player.plugin
flashplayer.xpt
Flip4Mac WMV Plugin.plugin
Flip4Mac WMV Plugin.webplugin
Google Earth Web Plug-in.plugin
Installer Log File
iPhotoPhotocast.plugin
ipxBrowserPlugin
JavaPlugin2_NPAPI.plugin
JavaPluginCocoa.bundle
npdivx.xpt
nsIQTScriptablePlugin.xpt
Quartz Composer.webplugin
QuickTime Plugin.plugin
RealPlayer Plugin.plugin
SpeedDownload Browser Plugin.plugin
