I recently noticed (though being using it for around a year) in my Nothing Phone (2a) that in complete dark environment, after turning the flashlight off there is a little glow for around 10s.
I think its because of the residue current but haven’t saw this behaviour on my previous phone and also I don’t think LEDs in good condition behaves like this.
Maybe I am just overthinking, but do you guys can also see this effect/behaviour and is it normal?
