'CCFlashLightLevel' Lets You Adjust LED Flashlight Brightness From Control Center
In iOS 7, Apple introduced a new toggle and shortcut feature called Control Center. Here, there's a new flashlight toggle button that lets you use the rear-facing LED flash on your iPhone as an LED flashlight without the need to download a third-party application from the App Store.
It's really simple to use, just tap once to turn the LED flash on, and tap again to turn the LED flash back off. But one thing that the toggle lacks is the ability to adjust the brightness of the LED flashlight. A new free jailbreak tweak called CCFlashLightLevel
by iOS developer PoomSmart fixes this.
With this tweak installed, you can tap and hold on the flashlight toggle button and a slider with a knob on it will appear on top of the button. Sliding the slider to the left will turn down the brightness of the rear-facing LED flashlight, while sliding the slider to the right will turn up the brightness of the rear-facing LED flashlight.
When you let the slider sit for a few seconds without adjusting anything, it will disappear automatically, allowing you to tap on the flashlight toggle button again to turn the rear-facing LED flashlight on or off.
The tweak adds a preferences pane to the Settings application where you can configure the amount of time in seconds that you will need to hold down on the flashlight toggle button to show the slider, and you can also configure the amount of time it'll take for the slider to disappear from the toggle button after not touching it for a period of time:
If you want to give CCFlashLightLevel a try, it's available for free in Cydia's BigBoss repository. The tweak does require iOS 7 and also requires an iOS device with a rear-facing LED flash.
