How to Get Flux-like Low Light Display Brightness On Your iPhone & iPad Without Jailbreaking It

By | May 12, 2015

If you want to change your desktop computer’s display color or make a dramatic reduction in the display brightness, you use Flux. With Flux, adjusting the color of your display for ease of use at light is a snap.

Flux not only makes it easier to see what’s on your computer screen at night, but it also uses a software-based filter to lower the brightness of your computer display beyond the limits of what the hardware can support.

Unless you’re an iPhone power user, you probably haven’t checked out all the options in your iOS’s Accessibility features unless you’re looking to solve an actual problem. There are some really useful features located there and it’s well worth the effort to check them out. It’s a great idea to check out the options available through the Accessibility feature. You never know what you will find there.


You can use Flux on your desktop computer to change the display color and it can also reduce the display brightness. You can find a similar feature in iOS buried in the Accessibility Settings, where you can access a low light mode but, it is not quite as powerful a tool as Flux for desktops. It just takes five simple steps to turn on this feature for a Flux-like experience on your iPhone or iPad without the dangers of jailbreaking.

By jailbreaking your phone you unleash unrestricted file rights and permissions. Jailbreaking means breaking your iPhone out of iTunes jail and it is the removal of hardware restrictions that Apple has put on its iOS system. This prohibited hack gives you a lot more flexibility, but there are some real dangers that come with the territory.

 Apple keeps tight control over what apps make it into the App Store to protect you from malicious software and to maintain a high level of quality. When you jailbreak you are introducing apps to your iOS device that potentially contain malicious software. At the very least, jailbreak apps vary in quality, and they could be exceptionally buggy or prone to crashing.

 So why can’t you just use Flux on your iOS device? Because it requires making changes at the system level, for example, changing the display brightness, and iOS does not allow apps to do that. The iOS alternative to Flux is the Low Light mode hidden in the Accessibility Settings. Low Light mode greatly reduces the display brightness, making a significant improvement in your reading experience in low light, and it won’t affect how you see your screen during the day. We’ll show you how to do this safely without jailbreaking.


Turning on Low Light Mode

  1. From your iOS device’s home screen, chose Settings ->General -> Accessibility and then enable Zoom.
  2. A zoom window will pop up on the screen. Ignore the zoom window and triple-tap the screen with three fingers to bring up the zoom menu.
  3. Tap “Full Screen Zoom,
  4. Select “Choose Filter” and then select “Low Light”.
  5. Return to the Accessibility menu. Select the Accessibility shortcut option and select “Zoom”.

This is a quick and easy fix to the low light problem without resorting to jailbreaking. Once you turn this feature on, you’ll be glad you did.
