Disable The Increasing Ring On Galaxy S
If you’re not a fan of the increasing ring when you receive a call on your Galaxy S, XDA forum member YG007 has put together a mod to get rid of that annoying fade in. Most Samsung phones have a ‘feature’ where when receiving a call, the ringtone gradually fades in to the volume that you have set.
In order for the mod to work, your phone needs to be deodexed. Additionally the mod is version specific so the modified apk must only be used with the same deodexed ROM.
You’ll need to put your Galaxy S into flight mode, copy the apk to /system/app/, and finally reboot your phone.
For more information including detailed instructions and the modification, take a look at the forum thread.
