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.
