Team,
***First off I am not responsible for damaged that occurs to any phones. Make sure you know what you are doing before making changes!!!***
I was having an issue with the mic gain recording distorted live concert audio so I was wondering how to access extended features on the Galaxy S.
The following is the code to dial in to access the hidden Service Mode menus.
Example how to access menus:
Dial *#*#197328640#*#*
This allowed me to adjust the mic gain to get better audio recordings at loud live concerts.
There seems to be several hidden menus on the Galaxy S and I am wondering how many more there are. Which led me to post this thread.
If any of you can find more hidden menus post them and i'll add them to this OP.
So far I know about:
Hidden Menus:
Service Menu: *#*#197328640#*#*
GPS Hidden Menu: *#*#1472365#*#*
Battery and General Info: *#*#4636#*#*
GTalk Service Monitor: *#*#8255#*#*
LCD / Speaker Test: *#0*#
Factory Data Reset: *#*#7780#*#*
Camera Information: *#*#34971539#*#* (Do Not Use The First Option "update camera firmware" you will break your camera)
Change Power Button Action: *#*#7594#*#*
Show IMEI Number: *#06#
Be careful in Service Mode that you know what it is your changing. If you hork up your phone you can reset it by doing a Factory data reset in Settings / Privacy / Factory data reset.
I would do a nandroid backup before making changes if your just experimenting.
I will add reference material below as I can:
__________________________________________________ __
Service Menu:
The following popular data communication technology is associated with each cell carrier type:
GSM = GPRS (2g), EDGE(2g), UMTS(3g), WCDMA(3g), HSDPA(3g) {Cell Carrier examples: AT&T and T-Mobile}
CDMA = CDMA*(2/3g) EV-DO(3g) WiMax(3/4g) {Cell Carrier examples: Verizon and Sprint}
Preferred Network types:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this.

Dude where you getting all these code. Nice find. You have any more? LOL
I don't which is which. I don't want to mess up anything on it.
Do you know how to work these setup menus?
Updated OP with more codes
I know how to get to the volume service menus in the phone, but does anyone know how to make the earpiece volume louder? My phone is too quiet when up to my ear (rocker volume maxed out) and I don't know what exactly to change in the service menus. I did it on my eternity but this one is a little different. any help is appreciated.

Several there that say RX, which one exactly? And what's the maximum possible value to make the incoming ringtone/text/email notifications louder? Thank you for all this, btw.

I noticed this as well. Very annoying. Anyone knows how to re-enable it ?

could it be that that's because the phone is locked and needs to be unlocked by the carrier

I found out that if you go into the dialer and type in *#*#197328640#*#* that it will take you into a menu that will allow you to change it. From the main menu of the ServiceMode screen, select DEBUG SCREEN, then PHONE CONTROL at the bottom, then UE STATE CONTROL. From there select CHANGE RAT TO WCDMA to enable 3G only, and select CHANGE RAT TO GSM for 2G only.

Give that a try.
YES!!!!!!!!!!!!!!!!
Thank you. That works! I've been trying for days to get it to work but it always stuck to WCDMA. THANK YOU.
kewl im glad you all figured it out.

Did we figure out how to max out the volume on incoming calls/texts? Samsung is notoriusly quiet.
What does this do??? (below copied from ealier post)

Turns off 3G, and uses only GSM and EDGE (2G) to save battery life.

I found a code on nother forum but can't remember where.. When entered it asked for a password and an IME number and one other number.. I found it by accident one day when searching for 'unlock captivate' and I think it brings up the same menu that is brought up when you use a foreign sim... Would allow unlock without requiring the insertion of a foreign sim..
Anyone know this code?
Today i flashed my HTC Touch HD with this rom (STONEHENDGE), Now for some reason i cannot get my 3 network to work atal.. Cannot make or recieve calls. It shows an exclimation mark next to the network signal icon. Also when i press find network in network selection it only finds o2 tmobile orange and vodaphone.
Any help? Is it maybe the radio needs updating?
Might sound obvious, but you have checked the UMTS band is 2100 (or Auto), and the phone has 3G enabled in comms manager?
If it's finding the 2G networks but not Three, sounds like phone is set to GSM only, sometimes happens ater a new ROM.
hello everyone, my nexus s 4g is flashed to boost, i been using it for 3 months without problems but in the last 2 weeks the internet was working too slow and i did a hard reset to the phone with the dial code (*#*#786#*#*)
after the hard reset the phone didn't have service because the msid and phone # changed, i went into cdma workshop and restore the msid and phone # and the phone was working again, i can make and receive calls and send and receive texts
but now my problem is that the phone don't show the 3g icon and doesn't connect to internet
i will appreciate if somebody can help me get the 3g working again
thanks
This may sound stupid, but s mobile data enabled in settings -> wireless & network settings -> mobile networks ?
If it is, then have you tried enabling airplane mode and then disabling it? There are times when my NxS drops 3G connection for no apparent reason and this is one way I can get it back.
I saw this posted in the radio guide as way to "retrieve 3G data connection"
Code:
1. Go to Dialer. Dial *#*#4636#*#*
2. Go to Phone information. Choose the preferred network to
"GSM Auto PRL" or "CDMA Auto PRL" or whatever you have.
3. Scroll down, deactivate and activate Phone Radio.
4. Press Menu button.
5. Select Phone frequency, then choose your country.
6. In the previous menu push the Home button to go back to Homescreen.
7. Reboot.

Hi, we just switched from US Cellular to Verizon, and apparently Verizon does not allow users to select just CDMA like USCC. The Verizon network is also very weak here in Maine it appears (much to my chagrin). We have so many dropped calls and dead spots is laughable - if you were not pissed anyway. I'm wondering if the difference between carriers that supposedly share towers, is that on USCC I stayed on CDMA for the improved data speeds and stability, and because it yielded better battery life due to the 15dBm stronger signal.
I'd like to switch us to CDMA and test it, but the android hidden dialer code does not work on the Note 4, but does on my MXP. Is there a way to switch to CDMA?
Thanks in advance,
Moose
Try this one, but not sure if it will work on your phone....
UE Setting Protocol Menu
[2] NAS
*#0011#
then on the top right (three dots) press it, then select BACK, then press three dots again, and select Key Input, on the next screen, you type Q0000 (capital Q and four ZERO's)
Wait a few seconds, then select the following from the succeeding screen:
[2] UE Setting & Info
[1] Network control
[4] Band Selection
Then select WCDMA Band, then exit and reboot
This is basically the same as my post for the S7/S7E - looks like the dial codes still works on the S8
My original thread
https://forum.xda-developers.com/tm...ng-network-t3331555/post65722081#post65722081
First want to put it out there that you do this at your own risk
I love that T-mobile has Band 12 LTE coverage but for me the data speeds on Band 12 are horrifically slow, so I prefer my phone to be on Band 4 LTE (at least while at work).
I used to do this change all the time on my S6/Edge and the steps are vary similar to do them on the S7(slightly more involved).
To start with, if you mess with bands, it can(and probably will) affect some sort of your service
So to change network bands you have to enter the service menu. To do this, go to the phone dialer and enter
*#2263#
Once here you will see a screen saying ServiceMode followed by various options
To turn off Band 12 choose LTE Band Preference (#4 on the list).
Then hit next page until you see Band 12 and deselect it (this will remove the * from next to it).
Once that is done, in the top right you'll see where it says "More" select this and choose "Back" - do this until you get back to the main page
Now back at the "Main Menu" choose "Apply Band Configuration" (option 7) and you're done.
Once you exit the menu(by hitting either home or the back phone key) you'll lose signal for a second while the phone switches the bands around.
To revert back to normal, enter service menue *#2263#, choose "Select All Bands"(Option6) and then Choose "Apply Band Configuration" and you're back to normal
Hope this helps someone
Interesting, How many others here find the need to change bands?
Wonder if its many, which case wonder what Tmobile would do to fix that.
