How to adjust flash brightness on Android phones and iPhones

We all know that the rear camera cluster of every smartphone from cheap to high-end today is equipped with LED flash. Besides supporting photography in low light conditions, this LED system can also act as a convenient flashlight to illuminate in the dark when needed.

We use LED flash on our phones quite often, but perhaps not many people know that the brightness of the light can be adjusted flexibly. Apple has long allowed users to adjust the brightness of the LED flash on the iPhone. While it wasn't until Android version 13 that Google added this small but useful feature. Let's learn how to adjust the flash brightness on your phone.

On an iPhone with Face ID, you can do this by swiping down from the top right corner of the screen. For iPhones with a physical home button, swipe up from the bottom of the screen.

When Control Center opens, tap the flashlight icon.

Flashlight Tiramisu is not available on Play Store. Instead, you can download the application as an APK file from F-Droid's official repository. F-Droid is one of the best websites for safe APK downloads, so you can rest assured that downloading the Tiramisu app from this website will not harm your device.
