Tired of your screen going dim while you're trying to watch Netflix? Do you want to read a lengthy article without constantly having to wake up your iPhone or iPad? This article will teach you how to turn off the auto-brightness feature in iOS 12 and take control over when your iOS device goes to sleep. Read on to find out how to turn off auto-lock and auto-brightness in iOS 12.

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

How to Turn Off Auto-Brightness

To turn off the auto dim feature in iOS 12, follow these steps:

  • Open Settings.
  • Tap General.
  • Tap Accessibility.

  • Tap Display Accommodations.
  • Toggle Auto-Brightness to turn the feature off.

You can turn this feature back on at any time by following the steps above and toggling Auto-Brightness to the off position.

How to Turn Off Auto-Lock

In addition to going dim, your iOS 12 device is 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, then you might prefer to turn off auto-lock or at least delay the feature. Here's how to turn off or delay auto-lock:

  • Open Settings
  • Tap Display & Brightness
  • Tap Auto-Lock

  • Set the lock feature to a time which works for you. The timer goes anywhere from 30 seconds to 5 minutes to Never. Keep in mind, if you set your iPhone to Never Auto-Lock then you'll want to avoid accidentally leaving your screen on and running out the battery.

That's how you turn off auto-lock and auto-brightness in iOS 12 to avoid having your screen go dim automatically. Now you can enjoy your movie viewing and book reading without all the hassle.
