    To use these codes, you simply open up your phone dialer, and type them in.

    ##786#. Tells you about the life of mins used and data. Also tells you if your phone is a refurb or not.

    *#28346# - Audio Tuning
    Has a lot of options including filters, boosters, equalizers and others. Can Mute Bootsounds, keytones, and other systems

    *#1472365# - GpsSetup
    Very useful tests for the GPS!!!
    Setup/Position Mode/ Operation Mode: (Standalone/MSAssisted/MSBased) Starting Mode: (Cold Start/Warm Start/Hot Start) Session Type: (Single Fix/Navigation) Setup/Command allows you to test the GPS and look at the results

    ##DATA# - Data Programming - Requires MSL
    User Name/Advanced/Restore/Enable HFA/DSA Server/MMSC/URL/Multimedia/WorkMode/WiMAX

    *#767*3855# - Factory Format - WARNING!!!
    Will go to Hands Free Activation
    Nice if you'd like to reactivate your phone, it will do so automatically

    *#745# - Sec_RIL_Dump - Has the LogFileList
    Copy to phone memory/Copy to SD card(grayed out)/View Ril Log(grayed out)/Clear Ril Log/Exit

    I haven't tested a dump yet

    *#9900# - SysDump
    copy logcat/dumpstate/dumpsys/enable debug log/copy/watchdogdumpstatelog
    Probably dumps the logs for the Operating System kernel
    I haven't tested a dump yet

    This has been posted several times, but I thought it might be useful for some people who may not have seen it.

    To get into the Android system recovery/Samsung Recover Utils
    Turn off phone, hold volume down, the power button, and the camera button at the same time to enter the recovery partition, and recover the phone
    Use Volume keys to move among options, and the Home key to select

    reboot system now
    apply sdcard:update.zip - Manually update from your SD card
    wipe data/factory reset
    wipe cache partition - Didn't do anything for me

    I hope you find this to be useful information. Feel free to add other codes you have discovered, or correct any misunderstanding I may have about what a certain code does.

    Added 2/5. I found this on xda somewhere. Its supposed to help lock on to 4g faster.
    Start this out with 4g and gps on, nothing else. MAKE SURE WIFI is not ON.

    1. Search for connectbot from market, install, click Open.
    2. click the little down arrow next to ssh and choose local
    3. for nickname, click once in that field, then enter just two letters (any letters are fine) and hit enter.
    4. open your physical keyboard for this one. type getprop (space) (hold FN key and hit the D key to make the | char) (space) grep ril and hit enter
    so your command should look like the following :

    getprop | grep ril


    5. Find ril.MSL and write down that number.
    6. Type exit and hit enter. Close physical keyboard if still open.
    7. Choose yes to disconnect the session.

    Now to do the fix :

    1. hit phone button to get dialpad up.
    2. Dial ##3282#
    3. click view, click WiMAX, click in field then enter MSL (the number you got from ril.MSL on step 5 above), then hit OK.
    Note: 4G radio must be on.
    4. A message should appear that says WiMAX_CFG is OK! If it says invalid lock code, then you dont have the right MSL number written down, or something else is wrong. if it says the OK message, continue.
    5. Scroll down to extensions and click it once.
    6. Hold EntyRX for 1 second. A menu should popup, click Write Extension
    7. Click the field, then write in -110 and click save (The Lower the weaker the signal can be for the phone to connect.)
    8. Hold EntryCINR for 1 second. A menu should popup, click Write Extension.
    9. Click the field, then write in 0004 and hit save.
    10. Hold Scan Retries for 1 second. A menu should popup, click Write Extension.
    11. Click the field, then write in 00015 and hit save.
    12. Hold ScanAttemptTimeOut for 1 second. A menu should popup, click Write Extension.
    13. Click the field, type 0002 and hit save.

    Now for the 3G port fix :

    NOTE : On Step 4 BE CAREFUL. If you click Advanced instead of Others here, the Service Menu should come up. DONT DO THIS. When you hit back arrow to back out it will reboot your phone, at least it did every time for me.

    1. From where you were in step 13, click the back arrow key 3 times. It should take you to Data Programming and you should see View and Edit menus.
    2. Click the Edit menu
    3. Click in field then enter MSL (the number you got from ril.MSL on the first set of instructions step 5 above), then hit OK.
    4. Click Others
    5. Click Multimedia
    6. Click HTTPPD Proxy Address. (write down what was there before just in case). Backspace over it and type in and hit ok
    7. Click HTTPD Proxy Port. (write down what was there before just in case). backspace over it and type 0 and hit OK

    Finally, click back arrow four times which should take you to dialpad.
    Reboot or enable and disable airplane mode from Settings > Wireless and network menu. If you want to reboot, you can use Quickboot here if you want.
    I've done it both ways and I think reboot is best, i seem to get the best bars after a full reboot when doing this.

    NOW, my results, findings, tests, etc.

    I played around a bit with the number on EntyRX since when I checked mine it was set to -00084. I moved it all the way to -00110 and around a few times to -00060 and others. Seemed to me -00094 was best for me. You also dont have to type all the extra zeros, but you do have to type the - sign in for the entyRX.
    See these threads for more details :

    My settings are as follows :
    ScanAttemptTimeOut 00005
    ScanRetries 00120
    IdleSleep 00300
    EntyRX -00094
    EntryCINR 0004
    EntryDelay 00001
    ExitCINR 00008
    ExitDelay 00300

    I also zeroed out the RTSP proxy address and port as well, seemed to work better for me.

    When you come back in, before doing speedtest, I recommend going to task manager in applications and clicking Ram Manager, then clicking Level 2 and clicking clear memory. repeat this 3 times.

    then hit home button. go back into applications and do speedtest.

    Your speeds should return fast speeds.

    One other note, if you are bouncing 4g disconnected on and off because you are in a spotty area, turn off 4g before testing 3g with speedtest. do airplane or reboot and ram manager clear above before the test, then see what you get for speeds.

    Last, I checked my PRL and it is 60674. I am using Bonsai 1.1.4.

    Please Excuse my Ignorance.

    I am wondering if there is a hack for me to be able to tether my Laptop to my phone?

    I am upset because they {sprint } wants $35 a month for this & when I bought it they said it would do it for the one set price I have a little more than a week to figure if I stay with it or not

    Please help me figure this out .

    I am not a knowledgeable person when it comes to this but a fair learner so easy with the abbreviations & nick names for stuff.
    My last phone was a Palm 650!

    Thank You

    If you are not rooted check out PdaNet and Easy Tether in the Android Market.

    You have to use the phones preinstalled dialer, not Dialer One or anything like that. (Just figured that out by giving it a shot. I normally use Dialer One)

    And now, for some reason, I can't use the codes either. Worked great for the audio, but only about half of the other ones work. Did hte codes change with gingerbread? I'm pretty sure the GPS one did, but the new one I found doesn't work either.

    This is the new one I found, but, again, it doesn't open any menu like the ones that actually work do. Someone else see if it works for them?

    You will not see those apps on the Market because Sprint is blocking them. You will need to get the .apk from their web page.

    Your 4g fix doesn't work because when I enter
    getprop | grep ril
    it says grep: file not found

    This didn't work on a Galaxy Grand Prime SM-G530P. There was NO ril msl. This thread looks old and things must have changed since then. Now I seen that it was for the Epic even though I was serching my specific Model. and see no way to delete this post.
