I am having the exact same problem with my iPhone 6 and Safari. Very frequently, when I turn the phone from the portrait orientation to the landscape orientation, the Safari screen goes to ½ size, with the top half of the screen black. Only ¼ (the top left quadrant) of the Safari screen is shown on the bottom half of the screen, although you can scroll within that space. Very irritating! Rebooting the phone gets rid of the problem, but it happens frequently, more than once a day.
Then you need to determine is it's a hardware issue, an iOS issue or a user data issue.
Basic Troubleshooting Steps when all else fails
- Quit the App by opening multi-tasking bar, and swiping the App upward to make it disappear. (For iOS 6 older, hold down the icon for the App for about 3-5 seconds, and then tap the red circle with the white minus sign.)
- Relaunch the App and try again.
- Restart the device. http://support.apple.com/kb/ht1430
- Reset the device. (Same article as above.)
- Reset All Settings (Settings > General > Reset > Reset All Settings)
- Restore from backup. http://support.apple.com/kb/ht1766 (If you don't have a backup, make one now, then skip to the next step.)
- Restore as new device. http://support.apple.com/kb/HT4137
For this step, do not re-download ANYTHING, and do not sign into your Apple ID.
- Test the issue after each step. If the last one does not resolve the issue, it is likely a hardware problem.
