Be careful when you use these secret codes. You can use *#*#5228378#*#* to enter into testlab mode :)

They look like phone hack codes like *#06#
-
How is *#06# a hack code? It’s been here since the firs GSM phones. It’s hardly a hack

-
I was just saying it's what they look like. *#*#4636#*#* Gives menu for displaying battery Wi-Fi CPU usage etc. Look familiar, doesn't work on all phones.
-
Actually you said that they look like hack codes ‘like *#06#’. English isn’t my first language but the logic of your sentence is clear. What you meant on the other hand is a whole other story though...
-
Well done on the languages. I have brain ache when it comes to different languages as you can see just about got a grip of this one. *#md# was a nice one before they done message delivery report, it was good getting your phone to do this. The pattern on the codes look the same
