Camera flash doesn’t turn on?
Using the flash eats up much battery power. To save battery power, the camera disables the flash (even when you have set the camera flash mode to Auto flash or Flash on
) when one of the following occurs:
You have an incoming call
The flash will be disabled temporarily when you have an incoming call. After the call ends, you’ll be able to use the flash again.
If you have set the flash to Flash on, it turns back on after you answer and end the call.
Your phone’s battery level reaches 10% or lower
Recharge the battery so that the camera can have enough battery power to use the flash.
Cold weather may lower battery performance which affects the flash
To make sure the camera has enough battery life to power up the flash, keep your phone warm. When not in use, put the phone inside your jacket to keep it warm, and try to avoid sudden temperature changes that may affect battery performance.
