Are you noticing your iPhone screen randomly lighting up when you touch it or move it? Even if you don’t have any notification (text, call, snapchat, etc) ? iOS 10 seems to enable Raise to Wake feature by default. This feature automatically turns on your iPhone display when you move it. To disable it follow these steps.
1. Go to Settings -> Display & Brightness
2. Find Raise to Wake and turn it off.
Now your iPhone screen won’t randomly turn on!
