IOS 4.2 very slow and unstable

since updating to IOS4.2 my iphone 4 has the following symptoms:
- very slow to pop up with the keyboard
- very slow when typing (keeps getting stuck)
- slow switching between safari pages, and loading other pages
- slow when scrolling on anything
- randomly crashes and reboots
- it gets worse and worse after 10-15 mins of use
- it has become borderline un-usable!
on 4.1 there was a few minor bugs but it was generally fast/stable.
i have looked on itunes to see if i can restore it to a previous synch'd version of 4.1 but it doesnt look like i can, without deleting ALL of my apps, texts, photos, favourites etc!
this has got to be the biggest **** up ever, not only is IOS4.2 terrible on the iphone 4 but Itunes software is the most clunky useless lacking program for updating/restoring the iphone anyway.
i guess the next IOS update will be 2 - 3 months away and it might still be unstable, i dont know if i can live with it that long, i might aswell send it back as its still on warranty and insured....

Well I haven't noticed any performance issues but some of you on here will time the opening of apps to the microsecond. My phone gets better battery and overall seems to be working better. The only thing I don't like is that this update promised air printing but only a handful of printers are supported. My wifi printer unfortunately is not.
According to Steve Jobs, there be updates for that:

Very slow and unstable after update...

Hello!
After update yesterday, my Arch64 was very slow and unstable... Eclipse IDE crashes, Firefox uses +200mb and Xorg uses +15% of CPU. Xorg lags when I'm going to switch between virtual desktop in KDE... very strange!

There is an in-kernel driver in staging called rtl8192u. It received a lot of changes in v3.12. Maybe try v3.11 and see if that works?
it didnt work in kernel 3.12, but with https://aur.archlinux.org/packages/dkms-8192cu/ it worked perfect
in kernel 3.13 it is horrible both witht he stock driver or with the AUR package.

I restarted my phone as suggested and it is still happening.
My phone just blacks out at its own will as if the battery went dead then the apple logo appears and it restarts on it's own but my battery was still at 30% when it restarted. So that made no sense. When I try to type in my password it freezes up before I can get all of the characters in. I still hear the clicks of my tapping on the keyboard but nothing is changing on the screen. When I hit the enter button on accident it vibrated to tell me my password was incorrect but still the screen was frozen with my previous entry of the first 5 characters on the screen.
I am becoming concerned that I may have a very expensive paperweight now.
My husband has the same phone and his is working fine after the initial reboot.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Go to Settings>Safari and Clear Cookies, Data and History
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.

Wireless very slow and/or unstable after Kernel update to 3.13

I have a "fresh" install from 2 weeks ago. It was installed with Kernel 3.12. I have a rtl8192cu, it was dreadful, so as recommended I installed dkms-8192cu and everything was perfect.
After the upgrade to Kernel 3.13, both with the standard driver and with dkms-8192cu my connection is very slow or unstable.
As an example, in theory I have 20m, with 3.12 I was around 14m. With 3.13 I am around 1m or less, I can barely update my system because:
error: failed retrieving file 's-nail-14.6.1-1-x86_64.pkg.tar.xz' from archlinux.polymorf.fr : Operation too slow. Less than 1 bytes/sec transferred the last 10 seconds
Wired everything goes fine.
I cannot downgrade to 3.12 because I need the new radeonsi improvements done with 3.13. I have this computer mostly to play Dota2.

I upgraded my three year old ipad to IOS 8 and it's working very slow and irregular, can I go back to the old settings?o

I recently upgraded my three year old ipad to IOS 8 and it's working very slow and sometimes freezes. Can I go back to the old system?

No, downgrading the iOS version is not supported by Apple.
You could see if any of the following improve things :
- closing apps via the iPad's taskbar : iOS: Force an app to close.
- if having problems with Safari, clearing its history and data : Settings > Safari
- soft-reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
- backing up (and copying any purchases over to your computer's iTunes library via File > Devices > Transfer Purchases) and restoring
- adjusting settings e.g. turning 'reduce motion' on (Settings > General > Accessibility), turning off 'background app refresh (Settings > General), turn off multitasking gestures (Settings > General)
- resetting back to factory defaults (after copying off purchases and any documents, photos etc that you want to keep) and then resyncing it back

Cover flow is very slow and crashes on iOS 5 or is it just my iPod Touch?

Basically, everytime I use cover flow on my music and scroll around it laggs and crashes. The simple solution is to not use it I know but I'm just wondering if you guys are having the same problem.

Same here on my 3GS. Found that restoring a second time the phone helps,no more crash,but still very slow and freezing,compare to flawless response on previous IOS3-4.
Note that looking at diagnostics reports,it have lot's of "LowMemory" and "awdd" messages with dates corresponding to the times is was using cover flow.
Even outside of cover flow,my 3GS registers lags corresponding "LowMemory" reports quite often.
I enable then sharing to Apple of those diagnostics on the phone,hope they fix this soon!

IOS 6 is very slow. Why!!! Can u fix that apple?

I have downloaded iOS 6 on the day it release and I have trouble with opening gmail on my iPhone and iOS 6 is very slow. I don't know what wrong with that. Did anyone know about it.

Try some basic troubleshooting steps. Clear Safari, force close the app and reset the iPad.
Go to Settings>Safari>Clear History, Cookies and Data.
In order to close apps in iOS 8, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
There re are ways to contact Apple directly. Look here for help.

My i pod touch screen is very slow and can't open the full page to close the voice over

my ipod4 touch sceen very slow and i can't open the full page can't scrow to close the voice over

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

IPad 1 getting slower and unstable

My iPad 1 is getting more and more slow and unstable. It has iOS 4.2.1 and I'm afraid to upgrade to iOS 5.1.1 because many says that it is too heavy for iPod 1. How can I restore to iOS 4.2 or, better, to 4.3?

No - Apple does not support downgrading.
Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps from the tray before doing the reset.
But frankly, I wold consider the upgrade. My son is currently using my old iPad first gen running 5.1.1. Works just fine.

XGL/Beryl - Damn slow and unstable

Hi,
I know, Beryl is quite unstable, but seems it works for so many guys, why not for me?
I followed this instruction: http://bbs.archlinux.org/viewtopic.php? … hlight=xgl
I have a Radeon 9600 and get KDE to work with XGL actually, but when I try to configure Beryl, the manager is so damn slow. And also the speed in general is very slow and after a while it crashes completely.
I have a Centrino 1.5GHz. This is not enough for the cool effects??
Im using fglrx btw. This is important?
Sorry if I ask for stupid "unstable-support", but I really want to know if its a stability problem of the software or if I made a mistake in my configuration.
Thanks in advance...
EDIT: When I use XGL as a session on KDE-Startup, the screen is white only and my notebook crashes (mouse still works)

glxinfo: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory
kwin: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory
beryl: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory
Then I installed the mesa-package:
compiz: No GLXFBConfig for default depth, this isn't going to work.
compiz: Failed to manage screen: 0
compiz: No manageable screens found on display :0
The window decorations are not visible.
