In a previous update, Apple hid the controls for toggling auto-brightness on or off. This change in settings has proven to be an annoyance to users who prefer to control the appearance of their screen, especially when an iPhone or iPad is being used for entertainment purposes. We've uncovered the lost controls for both auto-lock and auto-brightness on your smartphone and tablet, so that you don't have to dig.

How to Turn Off Auto-Brightness

To turn off the auto-dim feature, follow these steps:

  1. Open the Settings app.
  2. Tap Accessibility.

In addition to going dim, your iOS devices are set to automatically lock after one minute. While this particular setting won't affect your Netflix viewing, it will affect your reading. If you don't want to have to continuously tap your screen to keep the device from locking while you read the morning paper, you might prefer to turn off auto-lock, or at least delay the feature. Here's how to turn off or delay auto-lock:

  1. Open the Settings app.
  2. Tap Display & Brightness.

  4. Set the lock feature to a time that works for you. Keep in mind, if you set your iPhone's Auto-Lock to Never, avoid leaving your screen on and running down the battery.
