Test nexus 5x mic, earpeice, proximity sensor etc

[kevin connell]

Hi, I'd like to test the above functions on my nexus 5x.
In Sony phones you can dial #*#*7378423*#*# and it takes you to all the features and testing of your phone, but nexus doesn't seem to do this, can anyone please advise, thanks

There are sensor testing apps in Play.
