Thank you for the details of the issue you are experiencing with Voice Over. Try turning off the Screen Curtain by triple tapping the screen with three fingers.
Additionally, you can turn Voice Over off completely using these steps:
Press the home button three times quickly. This is also called "Triple-click Home".
If the VoiceOver feature still is on, you can navigate to Settings > General > Accessibility and turn VoiceOver off here.
If it is too difficult to access those settings on your iPhone, you can turn VoiceOver off using iTunes:
Managing accessibility features using iTunes
- Connect your iPhone, iPad, or iPod touch to any computer with iTunes installed.
- In iTunes, select your device.
- From the Summary pane, click Configure Universal Access in the Options section at the bottom.
- Select the feature you would like to use and click OK.
