Can anyone explain to me if they have this problem? Since downloading the new iOS system both my iPhone and iPad are having major problems. The apps are continually freezing, locking up, crashing and failing to open. I've had issues with the keyboard etc.

First thing to try to remedy would be a device reset:

Device Reset (won't affect settings/data/music/apps/etc)

1. Press and hold (& continue to hold) BOTH the Sleep/Wake button & the Home button.

2. Continue to hold BOTH (ignoring any other messages that may show) until you see the Apple logo on the screen.

3. Release BOTH buttons when you see the Apple logo and allow the device to boot normally.

Apple does not have an "email address" (per se) that I know of. You can leave feedback here:

If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."

At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.

If you're unable to do the Restore, read this.

I am having the same lock-up issues on my iPhone 4S. it keep locking up! Resetting as suggested is the only way to get it running again, but it still locks up.

Hello Apple - we need a fix here please. Siri is in a bad mood, so am I and the thousands who are experiencing the same on their iPhone 5's

If you would read my post just above yours, you would realize that there are other solutions.

Thousands? Naah.
