While you plant a c4 the merc is touching the little screen on the c4 while its activating and for what i saw the screen is dark and i tought it would be cool if he made a pattern to unlock the numbers (1,2,3,4,5,6,7,8,9,0) and then activate the bomb tapping in the numbers (like the bomb code in CS:GO). If you didn’t understand what i was trying to say comment 
Planting C4
I’m pretty sure they’ll add some visual effects to the bomb planting in the future. I just assumed it wasn’t a priority atm seeing as the game is still in beta.
It would be an interesting feature for non-tech mercs, to speedup planting. Otherwise its not worth it.
Even if defendendign team is half-decent, implementing mandatory sequencing plants will be a pain, not to mention that many players hate such features of questionable quality.

It’s visual only.
I never noticed the screen was static on the bombs. I’m usually too busy keeping an eye out for defenders adamant on blowing my face off 
If the C4 touchscreen is supposed to be like the numpad on our keyboards(starting with 7) the code is probably 744521. If it’s aligned like the CS: GO bomb keys(starting with 1), then the code is probably 144587.
Yeah, I have a lot of free time.
I’m sure they’re going to add it someday, just the priority won’t be high enough for it.
I thought the touchpad is dark on purpose, so only an insider can arm the bomb with the right finger movement.
what lovely community !
