Accidently turned down iphone brightness all the way

My daughter turned the brightness on her phone all the way down and I can't see anything to go to settings and fix it. I tried going into our pitch dark no window bathroom and still can't see anything. Is there a way to fix this?

I had the same thing happen just now. It can happen if you have auto brightness on and turn brightness to 0. The key is that Auto brightness is on. The sensor for auto brightness is on the front of the phone next to the ear speaker. Shine a bright light into the sensor (flashlight from another phone works great). The screen will light right up and you can adjust the brightness. You're welcome 🙂

My daughter did the same thing!


I discovered that this phone (for whatever reason) goes into black screen at about 25% brightness setting.


I agree there is probably a bigger issue with the screen or phone ... but this is how I was able to "rescue" it for my daughter....


We have the 30pin to HDMI connector and I used it to mirror the phone onto the TV. Then I navigated to the brightness setting using the TV display as a guide.


Hope this helps someone!!!
