On my samsung S9+

[Chiefgino]

On my phone Samsung9+ my dial pad for my phone app which is the one that came with phone work when I'm doing everything but when I go and punch in a code like *#*#4636#*# it should send me rt yo that setting but it does nothing and it's that way with any of the codes how do I fix this problem.
