iOS 4.3 iPod Touch issues
These are the main reported issues for the iPod Touch following upgrade to iOS 4.3.
Graphics issues following iOS 4.3 upgrade
There is a growing list of iPod Touch 4 owners complaints on Apple message boards about graphic issues following upgrade to iOS 4.3. Most of the issues seems to deal with lock screen notifications being glitchy, as well as overlapping icons and interference.
Both restoring and factory resets does not seem to solve the issue.
Slow performance following upgrade
Some iPod Touch owners are also reporting the device booting and opening apps slower than before they upgraded to iOS 4.3.
iOS 4.3 iPhone issues
These are the commonly reported issues for the iPhone following upgrade to iOS 4.3
Slowness and sluggish performance
According to the Apple Discussion post on this topic it looks to have primarily impacted iPhone 3GS owners, but there are also iPhone 4 owners that are reporting sluggish performance in terms of opening apps, and also sometimes when it comes to animation flow.
Personally i have also experienced some apps not running as smoothly as normal (including Twitter), but that again could be down to the app itself and not the iOS 4.3 ugprade.
Notifications draining battery faster
There are also plenty of reports of battery draining faster from what looks like notification system, so might be worth going through all notifications and switching off those that are not necessary.
SMS ringtone issues
Perhaps not a direct issue in itself, but Apple has shortened many of the pre-installed text tones as customers were complaining before that they were too long, while now they appear to be too short.
Video playback issues
It looks like the iOS 4.3 upgrade has had an impact on non-iTunes movie files that has multi-channel sound, causing sound to disappear or even movie not to play normally.
Layar browser app
If you have the Layar app for augmented reality installed you are likely to find it not working correctly, and that some images and icons are displayed incorrectly.
The Layar app uses the iPhone’s camera, accelerometer, and GPS to identify users location and view, and then overlays with information that might include information about buildings or location of cashpoints etc. Layar claims that the issue has come as a result of Apple changing the API, causing the the Layar client to fail.
