[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Tested Working Dialer Codes

Sorry I didn't get these posted last night....just couldnt keep my eyes open any longer!

Hey Joe, Hope you dont mind a quick correction. If I understand this stuff correctly, these are not USSD codes (USSD is in your title). USSD (Unstructured Supplementary Service Data) Codes are ones which communicate with the carriers network/computers. These are different as they communicate with the device hardware and software (mostly hardware related though). A simple example of a USSD code would be #646# to check your minute usage, or #225# to check your current balance. Also with the USSD codes you have to press the call button, with these you only have to enter the code, and if it is correct and enabled, it will execute automatically.

I have seen these referred to as Hidden Codes, Secret Codes, AOD (I think thats what I saw somewhere). I generally just call them Dialer Codes. Also, as per my understanding, there are Android codes and Manufacturer codes. So some of them are built into Android itself, while others are built into the mods made by the manufacturer.

Most of that is from memory, so if I made a mistake or jumbled anything up, please do let me know! I think Ive got it right though!

Note that Samsung disabled some of these in different builds, so while some may work on UVALEM, they may not work on UVALH2 or UVDLI8. (Different builds may have different codes disabled/enabled, but I have not been making a point to test them on each release)

I'll be adding these to one of my threads at some point as well.

The following codes have been tested and confirmed working on UVALI5. I have a lot more but have not had a chance to test them all yet, and some I have tested and are not currently working for me on my current build, so I am leaving those off as well. (also as op requested, I will only post the ones that should be safe to use. Some codes will wipe your data or have unwanted results. I am leaving those off of this list)

Unless otherwise stated, enter codes from the dialer like this: *#code#

273283*255*3282* --- Adjust/Fill Message, Contact, Call Log, etc Limits

*#*#4636#*#* --- Testing (Device Info plus some tests)

I have quite a few more. But have not tested for function or if they even work yet (or they didn't meet OP req.) Ill add more when I do, but figured I'd go ahead and share what I have already.

As I said before, Samsung disabled different codes in different builds. Ive already run across a few where they did not work but I am quite sure I remember them working before on a different build! YMMV.
