If the Flashlight is not working on your iPhone 12 or if the Flashlight Icon is grayed out in Control Center, there are a few things you can do to fix the issue.
The iPhone 12 comes with a number of useful features. One of those is the flashlight, which can be a lifesaver during times when you need a little extra light but don’t have an actual flashlight on hand or when you’re out of batteries. However, just like with any other feature, the iPhone 12 flashlight might malfunction. If it suddenly stops working, there are ways to troubleshoot to get it up and running again.
How to fix the iPhone 12 flashlight if it is greyed out or not working:
1. Close the Camera App
Both Flashlight and Camera App on iPhone are powered by the same LED light, which is located at the back of the device.
However, it is not possible to use both Camera and Flashlight at the same time on iPhone. Hence, if the Flashlight Icon is grayed out on iPhone 12, simply close the Camera App and you should be able to use the Flashlight.
2. Remove iPhone Cover
In certain cases, the problem of Flashlight not working on iPhone 12 or iPhone 12 Pro is due to the Flash Lens being covered by an ill-fitting or improperly designed iPhone cover.
Take a good look at the back of your iPhone and see if the Flash Lens is being blocked by the cover. Remove the cover from iPhone and see if the Flashlight is now working properly.
3. Charge iPhone
The Flashlight will not work if the battery on your iPhone 12 is almost empty. Make sure your iPhone is sufficiently charged and try to use the Flashlight again.
Also, make sure Low Power Mode has not been accidentally enabled on your iPhone by going to Settings > Battery.
4. Restart iPhone
Sometimes, the problem of Flashlight not working on iPhone 12 or iPhone 12 Pro is due to stuck programs, processes and minor glitches preventing the Flashlight from being used.
Head to Settings > General > scroll down and tap on Shut Down.
Allow your iPhone to shut down fully > Wait for 30 seconds and Restart your iPhone.
5. Turn the Flash OFF and ON in the Camera
Sometimes, the problem of Flashlight not working on iPhone 12 Pro or iPhone 12is due to the Flash being stuck in iPhone Camera App. To fix this, open the Camera on your iPhone > tap on the Video Icon and then tap on Flash Icon.
Next, select the ON option, followed by the OFF option.
Close the Camera and try to use the Flash on your iPhone.
6. Install Updates
Head to Settings > General > tap on Software Update.
On the next screen, tap on Download and Install (in case an Update is available) and follow the instructions to install the updates.
7. Reset iPhone Settings
Resetting Settings will erase your WiFi Password and reset all settings and preferences on your iPhone to factory default settings (it will not delete any data from your iPhone)
Head to Settings > General > Reset > select Reset All Settings option.
On the confirmation pop-up that appears, tap on Reset to confirm. After iPhone restarts, you will have to rejoin WiFi Network by entering your WiFi Network Password.
8. Force Restart iPhone
Press and release Volume Up > Volume Down > and then press and hold the Side button (ON/OFF), until you see the Apple logo.
If the above steps did not fix Flashlight not working on iPhone 12 or iPhone 12 Pro issue, the problem is likely to be hardware related and you need to get your iPhone checked by a technician at Apple Store.
