[Q] Missing service mode USSD in S4 i9505

Hi,
Got this spaking i9505 s4, but it seems the *#197328640# service mode is missing, im using this mode to select wcdma band, In my S2 it is there.
Did samsung removed : *#197328640#, if yes how do we access wcdma select band?
Also *#2263# is not working
Thanks,
Roy

Service mode:
*#0011#
Options*--> back
Options -->key input -->1
Black screen with number 1 up on the left

No I did not I ended up selling the phone as I wanted to change networks but I could not unlock the pjone.

Ei.. any fix for this?
i BELIEVE this is part of Samsung's "business strategy".. i was resolve this using the Samsung Service Mode apk (which I cracked and patched :highfive, however i have another issue related to this (see attached pic)!
In this case...may i ask if anyone from XDA knows the secret code for the UMTS Menu for me to access the Network Unlock menu???

RESOLVED thru SERENDIPITY!

Hi XDA Peeps!
I was able to unlock my i9505!
I just did the following steps:
1. Dial *#0011# via Phone Utility apk [Phone Connectivity Status will appear (via Service Mode)];
2. Tap on the left soft key (LSK) and select Key Input > Enter 1 > Hit OK;
3. Tap on the LSK and select BACK [You're now just a few steps away!];
4. Tap on the LSK and select Key Input > Enter 1 > Hit OK [Your screen shall have a different output now (i.e., a single digit "1" on line 1)];
5. WAIT for 5 seconds until the UMTS MAIN MENU appears > Select Debug Screen > Select Phone Control > Select Network Lock;
6. Next, tap on: [3] PERSO SHA256 OFF;
7. From here, go back to the UMTS MAIN MENU by tapping on Menu (left soft key on SGS4) and selecting Back from the options;
8. Once you are in the UMTS menu, tap on: [6]COMMON;
9. There, select: [6]NV REBUILD;
10. Now in the NV Rebuild menu, tap on: [4] Restore Back-up;
11. Samsung Galaxy S4 will now go into a temporary freezing state. After a while you’ll see some activities. The screen will be black and the LED will turn Blue. The Menu and Back key button on phone will also light;
12. Lastly, your Samsung Galaxy S4 will reboot automatically and will take a minute or two in booting up (depending on your ROM's Boot Animation);
BOOM! Your Galaxy S4 GT i9505 is now SIM-unlocked! Try a SIM card from another carrier to confirm the process and do not forget to share this to your friends too!

They disabled those dialer codes on the note 3.
You need to flash a different firmware, preferably one from your country or provider.

im not sure what hidden menu your talking about but on my note 3 i use *#0*# for testing things and 319712358 for changing frequencies, like what HSDPA or LTE to use... ect

If NOTE3 in Factory TEST MODE = FTM
Then all hidden keystrings are activated.

Lag gps galaxy note 4

Hi all,
In first, sorry for bad english, i m French lol.
I have a lag with my gps, i install ROM Dr Ketan for n910f. I want post on thread but I'm new user.
I want use this topic :
1) Open Phone, go to the dialer.
2) Enter *#0011# to enter the service mode. You will land at "DEBUG SCREEN"
I hit menu key and select "back"
3) Hit the menu key, select "Key Input" and in the Input Value box, enter Q (capital letter) and hit OK
4) Hit the menu key again, select "Key Input", and in the Input value box, enter 0000 (four zeros) and hit OK
5) Wait about 5-10 seconds, your service menu should change to "MAIN MENU":
Code:
MAIN MENU
[1] PROTOCOL STATE
[2] UE SETTINGS & INFO
[3] ETC
[4] DEBUG SCREEN(OPEN)
[5] OPERATOR(OPEN)
Now I haven't messed around in here too much, but if you want to reset your modem and GPS (restore the factory NV values for the modem, which COULD help data dropouts, bad GPS fix, etc.), do the following:
1) Enter the MAIN MENU as described above
2) Select option 2 "UE SETTINGS & INFO"
3) Select option 1 "SETTING"
4) Select option 2 "SYSTEM"
5) Select option 3 "NV REBUILD"
6) Select option 3 "ALL"
7) It will tell you to reboot. Do it. Reboot will take slightly longer, but it will completely reset the modem, GPS, and IMS settings
But a step 5, I wait , but any screen for select.
You have a solution ?? Plz
Thx

Anybody have solution ??

[CODES] Documented secret codes for OnePlus 5T

There was a thread noticing all the codes but they are not documented so this might be useful.
Disclaimer: I am neither resposible to accuracy of description of these codes nor any damage/loss caused by using codes improperly/recklessly.
Notice: Codes here are based on H2OS (which is the stock ROM in China rather than OxygenOS), so some of the codes may not be available in OxygenOS.
Language
*#008# : Change system language to zh-CN immediately.
*#67760044# : Change system language to en-US immediately.
Diagnostic
*#10000# : Show diagnostic results. If you have never cleared them manually or messed with diagnostic menu or functions before, this is your in-factory test result, which should be all OK.
*#800# : System logging menu.
*#808# :Don't operate functions recklessly in this menu. Diagnostic mode main menu.
*#802# : GPS test.
*#803# : Wi-Fi test.
*#804# : Mobile network searching test.
*#805# : Bluetooth test.
*#806# : Don't use this code recklessly since it would take long and may cause other issues if being stopped forcefully. Burn-in quality test.
*#807# : Auto test, which tests lot of things one by one.
*#809# : Microphone Loopback test.
*#814# : TD-SCDMA network searching test.
*#824# : WCDMA network searching test.
*#834# : LTE network searching test.
*#900# : Rear camera test.

*#6776# : Show more about software version compared to 1234 code.
*#888# : Show motherboard PCB ID and it's QR code.
*##*37847# : Show hardware components' model and suppliers.
Engineering
*#36446337# : Don't operate functions recklessly in this menu. Engineering mode main menu.
*#268# : Don't use this code recklessly as it may damage baseband. NV param testing and calibration.
*#801# : Switches for enginners.
*##*8110# : OTA test mode switch. This switch could probably be used for blocking OTAs.
Others
*#8778# : Factory reset. You will lose all your data.
*#911# : You may lose all your data. This would send you back to first-time setup page after reboot.
*#99# : Screen always on. Enter the code again to disable.
Easter Egg
Not sure if ever presented in OxygenOS.
