SAMSUNG A800 SECRET CODES

The universal unlock code is *2767*637# do this with out your sim in
By default, the firmware (software) for x600 only receives java
apps and other applications like stuff by serial port.
but even for it, you have to enable the serial port, which also
causes
the closing of all other ports, even the IrDA too :-( ..
well, guess what, i have very good news for you,
do you know, you can increase the sound level,

the sound level for tones, speaker fone, etc,
can be increase even then if it is at max (level 4)
you still can do it,
just follows the instructions!

**************** HERE WE GO **************
Enter the following code:
*#8999*8378#
(You'll be shown menu, then ...)
then go to:
"H/W test"
then go to:
"Audio Settings"

then go to:
"Melody Gain"

There will you see a number.
there are five (5) Melody Levels" of it.
(and currently, you are at level 1 and after
pressing the "save" button, you will move to
level 2 and so on .........................)
you have to change the values of all the levels.
and as the resultant, it will give increase the
melody sound!, your tones will more louder,
even more louder then the max. ringing volume.
the level wise numbers are: (as its my setting :-) )

Melody Level 1: 13
Melody Level 2: 17
Melody Level 3: 18
Melody Level 4: 25
Melody Level 5: 31
you even can make your own combinations of level wise
sounding numbers that can change the sound level!.

if your combination cause more louder sound level,
then mine,
then do share it with the group! ... :-)
meanwhile, try my figured-out combination!

************ CAUTION ************
if anything goes wrong,
then you can apply the master reset code,
that will NOT delete anything, ANYTHING from your
cell fone, but set each and eveything to its
default/standard setting ...
(likes, factory settings :-) )
the master reset code is:
#*7728#

#########################################
I take no responsibility of these codes are working or not,
or its effects on your cell fone
but i have tried these codes on my cell fone.
and i bet, nothing goes wrong,
but even then of my words, be carefull!,
#########################################
The code: *#8999*8378#
as i regarded it a informative code,
will tell you each and everything about your cell fone.
and in the "H/W test",
there are lot of other Audio settings,
each of them having five (5) levels,
you can change the combination, but before doing anything,
do write the defult number sequence to some place so that
you'll be then able to invert it again! .. :-) ...
