I want to change the codec from EVRC to EVRC-B on Verizon. Recently, I switched to Samsung S4 from HTC One. Before that, I had a HTC DNA. On these HTC phones, I can dial "##PROGRAM" to enter the edit mode. However, it does not seem to work on Samsung S4.
Does it have a special sequence to enter the edit mode? Thanks.
