How to modify the settings on your D900i Samsung mobile


I know this is a little of the ‘Macintosh’ topic but I thought I’d post it anyway.

Enter the number: *#8999*8378#

This will put your Samsung D900i into test mode and give you a new menu where you can change all the audio settings for the phone, all the gains (eg microphone, speaker) in various modes (eg handsfree, carkit etc). Make sure you take a note of the settings before you change anything so you can change it back.

The following abbreviations mean:

– Loud Speaker SUP : slide up
– Loud Speaker SDN : slide down

And the others are various versions of handsfree etc. post a note if you work them out.

    Is there a link to an online source where you can find out what ALL the abbreviations mean in the test mode menu? It gets kind of complicated in there, and easy to alter the wrong thing unless you know what the terms and letters mean. Thanks

    Hi, i don’t suppose you would know anything about the memory card in the D900i? I have had repeated problems with it not working, so i took the battery out of the phone, put it back in and it worked again. This, however, stopped making any difference, so i took the memory card out, but can’t get it back in again! i had to push it in to get it out, ithink it has some kind of spring system, but it just wont click back in so i can’t use it. If you know anything about this that could help i would be extremely grateful!

    Thanks a lot

  4. Sorry Bob, no idea. Have you tried a different memory card to make sure the one you are using is not faulty?

    Sir, Iam from pakistan. i want to know that in D900i there is FM radio in it. because official web site of samsumg show that there is FM radio in it. But some web sites do not show this function. Sir can you please give me information about this. please contact me on my email.

  6. Yes there is an FM radio in it.It uses the headphones as an antenna so it only works if the headphones are plugged in. It sounds very good.

    I think this is very good phone, but my question the game in this phone is trial game or not??

  16. Hi
    That you have gone into this level of detail is amazing.
    I’m trying to get my wife’s phone (Samsung sgh-d900i) text messages (precious to her) across to an iPhone 4 to bring her into the smartphone age. Contacts appear ok – they are on the sim. Can’t seem to download sms’s to a micro sim In the phone as it isn’t recognized by the phone – maybe has to be formatted by the pc-based utilities pack.
    Do you have any ideas?
    I’m in Canberra.
