ELI5 : Why do phones and tablets power on and off with full 100 % brightness regardless of the scree brightness settings?
In: Technology
For two reasons.
When the hardware fires up, it makes sense to perform a function test. I.e, run it at full capacity for a while and monitor that it appears to work.
And…the program that tells the screen hardware what brightness is preferred, that program is not up and running until the entire operating system is done booting up.
So. Those two in combination. It does that because it has been told no different. And it also makes sense to let it, because you can have a quick look at how it behaves to spot issues.
