Getting the most out of your i8910HD: Manufacturer Codes

with 14 comments


As I mentioned in my review of the Samsung i8910HD, there are several manufacturer codes that can be used to tweak performance of all sorts of different features. While the phone is very capable out of the box, it’s a real advantage to be able to access these hidden settings to tune your device exactly to your liking. In this brief, I’ll go some of the major tweaks, how to perform the tweaks yourself, and how to not damage your phone in the process.

This list is my compilation of information found on the Samsung i8910 Omnia forums and all credit goes to Briggs and the members. If you’d like to read about more device codes to experiment with,  please feel free to give them a visit and say thanks if you do.

Before you attempt any of the codes found in this guide, I want to warn that it is not clear what implications this may have on your warranty. While this guide is safe to make minor improvements to the i8910HD, I take no liability for any damage you do to your phone if you experiment outside the parameters of this guide, nor if your warranty becomes void from performing any of these changes. You are making alterations to your device at your own risk. It is also recommended you write down the previous values for any settings you change in the event you want to change them back to default.

3G/UMTS Tuning (*#2263#)

If you’re in the US on AT&T’s 3G, there’s no reason to have your i8910HD operate on any UMTS frequency than 1900. Although the normal settings menu only supports switching between GSM, UMTS, and Dual mode, you can use the manufacturer codes to turn off the other two UMTS radios.

From the dialer on your phone, type  *#2263#  . Press the number 2 on the onscreen number pad for “WCDMA Band Preference”. It should show a star next to the first option, “WCDMA All”. Press 4 on the number pad and then press “OK”. The menu should now have a star next to the “WCDMA 1900” option, locking your UMTS radio to only that frequency. You can follow the screen shots below for reference.

Changing this setting is beneficial for two reasons: it will save the phone from searching for two UMTS frequencies that aren’t available in the US, and it also allows a 3G connection to be made much faster often in less than 3 seconds!

Audio Tuning (*#0002*28346#)

If you find the audio to be too low when you’re on a call, there’s a code for that too. Type *#0002*28346# in the dialer to enter the audio tuning menu. From here, press option 1 for Voice call. This menu will present you with 5 options for all the various output devices, including the Handset (ear speaker), Handfree (loudspeaker), Headset (mono wired headset), Headphone (stereo wired headphones), and Bluetooth (wireless mono headset).

Before you continue, BE CAREFUL with these settings. If you change any of these values too high, it is possible and likely to blow any of the speakers. I urge you to make only minor changes and if you do want to test higher values, be sure to turn the volume down on your headset before allowing the device to emit any sounds through any hardware.

Handset and Bluetooth Headset Volume

I personally found the earpiece quality adequate, but I thought it would be better if I could turn it up a bit. From the Audio Tuning menu, press option 1 “Voice Call”, and option 1 again for “Handset” as shown above.

You can compare my screenshots below to your phone to see the differences. You can see I have changed the Tx Channel and Rx Channel both to 12 dB. I wouldn’t recommend tuning this value any higher to avoid distortion and risk potentially damaging your phone.

To change the values, tap the line you’d like to change, and you’ll be presented with a black tuning screen. This screen shows you the default value, the current value, the lowest and highest you can set the values, and what increments are used to change each value (Step). Following the Step value, you can type in the numbers you’d like to change the values to, and press # to set them.

I also felt that the volume of my Bluetooth headset was a bit low. Press back until you get to the Voice Call menu and select option 5 “Bluetooth”. I recommend changing the Tx Channel to 18 dB and the Rx Channel to 6dB. (notice the Step value is 3 dB in this menu instead of 1 dB  in the handset settings. This means that you can only change the values by multiples of 3).

When finished making your changes, press back until you get to the first Audio Tuning menu, and select option 6, “Backup”. This will finalize all of the changes you made so that they will remain after you’ve restarted or reformatted the device. (Note: all of these settings will be set back to their defaults when new firmware is installed).

MP3 and Video Playback Quality/Volume (settings recommended by Briggs)

Although I am satisfied with the audio quality of MP3 and video playback, some have commented that it can be too quiet or would just like to get better quality sound. Also in the audio tuning menu, option 2 “Play Sound” allows you to adjust these settings to get fuller, louder playback through both the loudspeaker and headphones.

In the “Play Sound” menu, select option 2 “MP3 HeadPHN”and change option 4 “HS Gain” to 6 dB. I don’t recommend changing this setting much higher since it may not only damage your headphones, but it could also damage your ears!

Play Sound Menu

Now to improve the volume of video playback for videos, select option 3 “MP4 LoudSPK”. In this menu, change option 4 “PreDR Gain” to 6 dB. Again, I don’t recommend changing this to anything higher since it can very well damage your external speakers on full volume.

Don’t forget to use the Backup menu to save your settings!

Camcorder Microphone Sensitivity

When recording video in very loud environments, it is common for an unnatural hissing noise to be captured due to the microphone sensitivity. There is yet another manufacturer code to change the sensitivity of the microphone to boost performance in general and also allow you to capture audio correctly in said loud environments.

Once again in the audio tuning menu, press option 3 “Record” and then option 4 “CamcordARM_AMR”.

In this menu, select option 1 “Tx MicAmp” and change the value to whatever you’d like (by multiples of 6 as shown) as you did for the any of the audio settings above. I have mine set to 18dB for everyday recording, but you can also change it to a much lower value if you anticipate recording in a very noisy environment like a concert or similar.

Again, don’t forget to use the Backup menu to save your settings!

  1. Once again Thanks, i thing i did notice is when i changed my settings for the umts and set it for 1900, my device then did not even connect to edge, which then left me with no signal in my basement where my 3g is only 850.

  3. I’d have to advise against tweaking these audio settings. There is a bug present in certain firmwares where even a slight change in the settings can cause the pbgain to shoot to 100 at any time causing speaker damage. This has happened to a number of people and my Omnia is currently in for service because of this.

    • Thanks for adding that. Can you post what firmware you’re running to avoid using with these tweaks?

      I’m running Italian IG2 and haven’t had this issue yet.

      • Happened to me on IE4 and IE7

  4. Thanks for this post – the UMTS tuning piece was really helpful.

  5. I have a question…. why is there also an option for 850mhz WCDMA?? Why not enable it?


    September 1, 2009 at 6:27 am

    • The manufacturer menu is generically designed to support multiple devices, which is why WCDMA 850 appears at all. Enabling it won’t do any good since the hardware for that frequency simply isn’t there.


      September 1, 2009 at 1:14 pm

      • gotcha… I figured this had to be the case. Generic f/w menus.

  6. I really like this phone. The only valid reason for me not buying this phone is because stupidly Samsung’s PC studion and Nokia PC suite doesn’t work on the same machine.
    Any suggestions around this problem? I want to keep using my trusty e71 along with i8910 beast.
    Will OVI suite v.2 work with Samsung PC studio on the same machine?


    September 1, 2009 at 10:42 pm

    • They both work on my PC.

  7. After searching for hours how to increase ridiculously low volume of headphones while watching videos on Innov8 (samsung i8510) i have stumbled upon your post and amazingly all of these codes work.

    Thank you for your great post, it was a life saver!

  8. I purchased the I8910 to watch videos on long airplane flights. To my dismay, I could hardly hear the audio over the airplane engine noise. I’m using a good pair of Shure ear-buds. The audio was fine on my iPod. Thanks for the info on how to increase the audio, I will try this for my next flight.
