Samsung - SGS3 secret codes for HSDPA/3G switch known?
before I bought my SGS3, I owned a SGS1.
For the SGS1 there was a secret code which allowed me to switch off any HSDPA / HSUPA traffic but limit the data to pure 3G UMTS.
This saved me a lot of battery, so I always used it.
The code was: *#301279#
Unfortunately this code stopped working already with the SGS2, so it does also not work for the SGS3.
Does anybody know some secret codes, might be the one I am looking for is contained?
