Messing with my Samsung’s F480: How to make the speaker louder

I was playing with my phone, until I stumbled across the “debug” screen.

This screen, is a place where all the internal systems were placed. For example, if I want to modify the “rock” equaliser, the phone’s normal UI won’t allow me to do that. But I can still create my own EQ settings for the way I want it to be. Or if I find the speakers too soft for my liking, I can make it louder.

DISCLAIMER: If you attempt this, you are liable for your own damages at your own risk. Please do not attempt this if you’re uncomfortable with “messing” with your phone’s settings.

NOTE: If you leave your settings too long, if might damage your speakers in the long run. Please do not tamper with the settings unnecessarily unless you want it to be.

Interested? Read on.

From here, press the “Dial” option. Key in *#06# and you should get your IMEI information.

You should see a bunch of numbers from 0-9 including * and #. They are your virtual keyboard. Now press “7″ and you should see some settings. Keep pressing “#” until you reach a menu that has “Debug Screen” option. That’s the main menu.

How to read/use them

[1] (Description) – These number enclosed in square brackets are your option. If it shows “1″, pressing “1″ will enter that option. The words beside it tells you that the option’s name.

How to go back

Pressing the “#” key acts like a back key. Note that the “*” key is mapped to the “0″ (zero) key. I think that this is a bug.

What to do next?

Press “8″, then press “3″ to enter “SPK Config”. This allows you to set your speakers volume. Now press “4″ to enter “AV-QTune(MP3)” option.

Select option “1″ to enter “SPK MP3 Vol[ ]“. The [ ] brackets indicate that this is changeable, and resetable to default. If there a * inside the [ ], which looks like [*], it means that there is a user setting there.

Now if you open that, you should see a bunch of weird numbers. Let me tell you how to read them.

The page says “SPK MP3 Volume, READ”. You are now in the “READ” mode, which means, if you select any options (from 0 to 6), you can overwrite the setting to your own one.

Here’s a sample:

0.[2] rx:-8.0dB

…

6.[14] rx:-8.0dB

That those numbers means are…

0 (the number zero) – the first character. That’s the option number. If you press 0, you will get a “WRITE” option, which I will discuss in a while.

[2] (after zero) – that is your “volume settings” number. Try pressing the volume rocker while playing an MP3 file, you should see a volume meter which reads from 0-14. The number “2″ essentially sets the volume setting at “2″ position. This is a bit tricky to explain, but I hope you understand.

rx – I don’t really know what this means.

-8.0dB – This is your volume strength. It is now running at negative 8 decibles (if you study physics you should know sound is measured by decibles), and that’s why you might get a lower volume.

So since you are trying to get the loudest speaker volume, IGNORE numbers 0-5, we’ll concentrate on option “6″, which gives you the power to set for volume setting at “14″ (which is the loudest setting you currently can get).

Can understand all of that? Then continue reading.

Press “6″, and you should see that the page changes to “SPK MP3 Volume, WRITE”. You are now in the “WRITE” mode, which means, any number you press now will take effect to the option you chose earlier. Now, to get the loudest setting, press “9″ and a change will take effect. Press confirm, or the “hang up” key to exit this screen.

Now you are back to the “READ” mode, which you don’t need to do anything else. Your loudest volume setting is now at 0.9dB louder, so essentially you can hear your music blast louder than usual.

Don’t believe me? Try playing an MP3 file, and you’ll see what I mean. You speaker should crack, because you are trying to make the speaker go louder than Samsung wanted it to be.

NOTE: You cannot enter a negative value or a positive integer number. If anyone figures out how to do that, please share with me.

I want to reset!

Surely you don’t want to damage your beatiful baby right? Don’t worry you can reset to defaults.

First, enter the “Main Menu” screen as I showed earlier. If you don’t know how, read this whole post again.

Now press “8″ (Audio) then press “6″ (Rebuild). “Rebuilt” is like restore. Next press “5″, and just “Rebuilt ALL”. This will essentially change back all your settings to the factory default for any changes you’ve made earlier.

NOTE: If you made changes to the “EQ Config”, the changes are harder to reset. I’m still figuring out the correct keys to reset that properly. Now all my EQ are set at a positive values, which sucks though.

So liked the louder speakers? It doesn’t make any difference though. The F480 is not a dedicated music phone, hence there’s really NO REASON for you to make the speaker louder. But if you’re adventurous, just mess with the settings like how I did to mine.

DISCLAIMER: I WILL NOT BE HELD RESPONSIBLE FOR DAMAGES CAUSED TO YOUR PHONE WHILE MESSING WITH THE SETTINGS. SOME SETTINGS ARE NOT MEANT TO BE CHANGED, SO PLEASE DO NOT COME CRYING TO ME SAYING THAT YOUR PHONE IS BROKEN/SPOILT BECAUSE YOU TRIED TO BE ADVENTUROUS. REMEMBER, EVERY RISK TAKEN IS YOUR OWN RESPONSIBILITY.

Well, I’m definitely trying to figure out what other settings I can change via this “debug screen”.

Good luck!

P.S: If anyone is making a video for this, please let me know! I want to see it.
