Notification LED on S5 mini costumastion??

A

AC Question

Hello to all!
I have a S5 mini, which has a notification LED. Unfortunatelly, I have come to the conclusion that the LED behaves differently on different apps. For example: when I recieve a notification from Trivia Crack (a game) the LED blinks fairly frequently, but when I recieve a message on Viber the LED blinks furstratingly slow (once every 8-9 seconds). It is actually easier to press the home button to check my notifications than stand there like an idion staring at my phone for 9 seconds to see if i have a notification....
Is there any way I could costumise the frequensy of the blinking??
Thank you in advance!
