Do dialer codes (such as *#debug) work on Samsung phones?

[avb]

Picked up the Galaxy S3 last week and was wondering if there's anything similar to *#debug# (33284) that I was able to do on HTC phone.

the codes used on my GNEX is *#*#DEBUG#*#*

Also *#*#4636#*#* is the test menu

*#*#checkin#*#* forces the phone to check for any OTA

On the GS3, the Debug dialer code is:

 

##DEBUG#

 

And the Lock code is 777468.

They launch hidden utility apps. Such apps often can also be invoked by making a shortcut within a third-party launcher such a LauncherPro in lieu of Touchwiz. Yet another method that might work is a standalone laucher app such as QuickShortcutMaker, which seems to work with many hidden utilities on my Samsung Epic 4G. (I don't have a GS3.)

 

These methods might launch some LTE utilities on the GS3, which we don't know much about. It may be that this is a route to try tweaking the LTE/EVDO fallback thresholds, as Robert has suggested.
