Use the code to testing, go to phone info, menu, baseband.

So what is a working example for Activity or Class?
Does the . needs to be there?

I tried for example:
am start -n com.samsung.ServiceModeApp/2263
and
am start -n com.samsung.ServiceModeApp/.2263

does not work.

My problem is, I dont know what to enter for ".PlaceActivityorclasshere".
For that, one or two examples would be nice.

That would work if 2263 was the actual name of the activity use the android manifest to get a list of activities and put those with the am start -n com.samsung.ServiceModeApp/.Activitygoeshere

the . is VERY important without it they wont start

Hi guys. Very useful information.

Do you know if there is any way of accessing the codes programmatically?

I'd like to be able to have some RIL information on a log in order to check the network performance of my app. I looked at Samsungservice.apk smali code to see how this data is obtained in order to pipe it somewhere else but I couldn't get anything clear from that.

am start -n com.samsung.ServiceModeApp/.ServiceModeApp
doesn't work.

am start -n com.sec.android.app.servicemodeapp/.ServiceModeApp
works, but crashes the com.android.phone process.

What am I doing wrong?!

U aren't doing anything wrong just u can't run that its causing a problem so they a different activity that seems to crash on all Sammy including the charge

Sent from my SCH-I535 using xda premium

*#*#197328640#*#*

That code doesn't work on my international s3. But It works (main menu of ServiceMode shows up) if I strip it down, like this: *#197328640#

*#*#4636#*#* is not working on Rogers SG III (i747w).
Used to use it all the time on my HTC Raider (Rogers) for checking 'accurate' signal strength etc.

On some mobiles you may need to enable the hidden menu before being able to access it with the "menu-code".

For example, for the Verizon SGS3 (GT-I535) you have to:

1. Open the keypad and dial *#22745927
2. Enable hidden menu
3. Go back to the keypad and dial *#7284#
4. Click Qualcomm USB Settings
5. Select RMNET + DM + MODEM and click ok
6. On your computer, open up Device Manager
...

And for the Sprint SGS3 we have some dependencies on the ROMs/firmware used as show in the thread:
[HOW-TO] Enable USB Diag Mode in AOSP

Below are two scripts to enable/disable USB Diag mode on the Samsung Galasy S III. This should work on all CDMA carriers on both Touchwiz and AOSP roms. Curious to hear if this works on Evo LTE AOSP builds. Thanks to toastcfh for the help.

On Touchwiz you can go to the dialer and hit ##3424# > USB Settings and select DM + MODEM + ADB. But for CM10 and AOKP, the scripts must be used. Diag mode is mainly needed to use QPST and other similar CDMA tools... QXDM, CDMA Workshop, DFS, etc.

Also please:

If you post new codes, REMEMBER to specify what model (and firmware) it applies to.
