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 15% 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.
