And you are sure that the screen orientation is not locked because you do not see the lock icon in the upper right corner of the screen correct? Because if you do see the icon - the screen is locked.
just to make sure .....
If you see a lock icon in the upper right corner of the screen - then the screen orientation is locked.
Try the side switch above the volume rocker first and see if that unlocks the screen. If that doesn't do it, double tap the home button and swipe to the right and look for the lock icon all the way to the left.
If the screen is unlocked but still will not rotate, reset the iPad.
And you did reboot the iPad this way? Reboot 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 - let go of the button.
So if you are certain that the screen is not locked and you performed the reboot successfully - You can try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your app preferences and device settings again.
If that doesn't do it, you may want to try restoring from a recent backup - one that you created when the screen was still rotating properly. When you restore from a backup, you restore everything in that backup, so of it has been a while since you last backed up - you may want to think twice about trying it
How to backup and restore from a backupIf that doesn't help, then try restoring the iOS software and see if that cures the problem.
So, i tried resetting all settings and it is still an issue. I can't locate a backup point, nor can I figure out to possibly revert back to ios5. I verified the screen orientation is not locked.
The odd part is that when I reset, the apple logo during reboot is right side up, but then when I get to the home screen, even when holding it rightside up, it comes up as upside down and does not rotate from there.
Can I assume that the screen is not rotating in any app? It behaves this way no matter what app you are using? What I am getting at is that some apps will not let the screen rotate. If by some chance you do h ave one of those particular apps, maybe it created a conflict that locked the screen and now you can't get out of it.
Have you tried closing all apps in the recents tray and rebooting the iPad? It's easy to do and it won't hurt anything, so try that now.
Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Keep swiping along the bottom in the recents tray and makes sure that you close every app. Tap the home button or anywhere above the task bar.
Reboot the iPad as described above. See what happens now.
I actually went a step further and deleted all apps that I have added recently and then cleared the recents and rebooted, and again, the apple logo during reboot was right side up, but home screen was upside down and will not rotate. Also tried launching an app that works in landscape mode. That one worked, but would not flip to the other side like it used to.
This is going to sound bizarre, but I have read about it on this help site and a couple of users swore that it worked.
Try turning your iPad over (face side down) and tap it on the back a few times - carefully and not with a whole lot of force. Make sure that the screen is totally protected - set the iPad on something flat and stable.
The only reason that I can see this working would be that it restes or unsticks the gyroscope assuming that it is stuck.
When did this issue crop up for you? Did you update the iPad and then this started to occur? Was it totally random? Were you doing something or working in an app and it suddenly started without cause?
I really don't know if restoring from a backup would help or not. The backup contains app data and device settings. Using my own deductive reasoning - whatever that is worth - if the screen was rotating when you last backed up the iPad, whatever the settings were on the iPad at that time that were allowing the screen to rotate properly - should be restored to the iPad - and the screen should rotate again. But .... Just because I reason it out that way doesn't make it a sure bet.
What doesn't make sense though is that if you reset all settings and that didn't help, then restoring from the backup will probably yield the same results.
How to backup and restore from a backupOther than restoring the iOS software, I am now at a loss. For whatever reason that we can not figure out, the rotation setting has been corrupted - or so it would seem - and I can't think of anything else to try.
first of all: Sorry for my bad english

I had the same problem, directly after updating my iPad2 to iOS6. Orientation lock was definitly not activited - I tested with software-lock from the dock and with hardware-lock on the side of the iPad.
I tried different ways to get back my screenorientation
First recovered the factory defaults, then restored from backups and at last I started it as a new iPad and not from an iCloud-Backup. I tapped the device (funny idea), but this didn't work also.
But now... it works!!
I runned the iPad-Power lower than less.
1% left and when the iPad was shuting down, I didn't connect the cable, I pushed the power-button again and again. The iPad shows the "oh, please charge me!"-Icon, but I didn't
Yesterday I pushed the power-button some times, but still didn't connect the cable.
Today I pushed the power-button 60 seconds and after that I tabbed all sides from the iPad (really funny idea, but I can't loose, so why not ) and then I connected the power-cable and charged the iPad.
After some hours I started the iPad ... and it works
Later, after finishing party, I restored to factory defaults again and restored a backup from iCloud from the time the screen orientation didn't work ... it workes.
Luckily, I actually ran into a different solution that fixed it. I took Demo's advice on the "tap the back" option, and initially it didn't work. After rebooting numerous times, resetting, etc., I actually stood it upright (with the screen display still upside down) and tapped it on a solid table. This must have unstuck the gyro and spun it back around. Seems like it was a HW issue, but needed to try a different 'tapping' method.
Mine just showed up locked did my wife's a few days ago. What is going on? Is Apple updating our settings or something when were not looking? Anyway I did see the rotation lock symbol with a lock in a little refinish arrow around it next to the battery gauge. So I went to settings select general and then click use side button to lock rotation as soon as I clicked it freed up and it is r rotating again. Hope this helps.
