Changing Screen Lock settings on iPhone 6S
I have an iPhone 6S running iOS 10.1.1. I have discovered that the screen locks automatically after one minute if I don't touch the phone, which can be annoying. I went into Settings to change the amount of time, but I can't find the Auto Lock controls. On my iPad, they were under General. Where do I go on the iPhone?
Go into Settings> Display and Brightness> Auto Lock. Once there, you can adjust the amount of inactive time that must elapse before the iPhone locks. Available options go from 30 seconds all the way up to "Never."
