I've heard about the soft ringtone but I found this comment on gsmarena.com,"MAKING THE PHONE RING LOUD (NO SPECIAL CODES) !!!
Hi guys,
I found accidentally the way to make the phone ring really loud.
1. When you set up your profile, you set up the loudness of the ring.
THIS IS NOT ENOUGH !!!
2. HERE GOES THE SECRET:
There is a second way to adjust the (already set up in profile) loudness of phone ring. While receiving a phone call - USE THE VOLUME BUTTONS to increase the loudness !!!
THAT IS THE WHOLE STORY
I just took my home phone and did adjust the ring loudness for each & every profile and it works beautifully. My phone rings now however loud I want.
(If this will not be enough for you, use a freeware soft called "mp3gain" to increase the dB value of you favourite ringtone.)
Forget about any special codes, dramatic comments on forums etc., etc., etc ...
Samsung did give us a next option without telling it anywhere

Should this guy be trusted?
