Not sure what this code is used for, but all Samsung codes should be in the format *#xxxx#
If you mean secret codes, you can obtain all secret codes by using these apps: Phone INFO ★Samsung★ app or Shortcut Master app
Open those apps > Menu > 'Secret Codes' > select the code and tap Launch.
Does anyone know how to access the Special Menus and hidden codes for this device on either the U Firmware/Software build or Stock. I am asking because I am trying to access the SimToolKit and certain engineering/Debug menus.
Hi Guys,
i have a problem with my Note 4. I attached a screenshot and you can see that there is no Preferred Network Mode option in it. I also try the code (*#*#4636#*#*) for hidden menu to change it but nothing happens coz when i changed the setting from GSM/LTE/Auto to GSM/CDMA/LTE/Auto and go back from the menu it will be revert automatically.
Can someone fixed it or have any solution???
Is there any one to help ????
I believe it requires a build prop or csc code edit that requires root for the settings menu but the service menu method should work as long as you do it correctly...and I say correctly not assuming your doing it wrong but to encinuate that there is a certain way you have to enter the keys..... Google it and you should be able to find a video
Hi guys.
When I enter this code " *#*#4636#*#* ", the secret menu appears but when opening "Phone Information" menu, It says "This application does not work on this device".
I tried to enter this menu in various ways but the result is simillar.
I need this menu to force my SIM2 LTE Only.
Me too in 990ds
Thats weird
There was a thread noticing all the codes but they are not documented so this might be useful.
