I want to increase sound in my samsung e250 but pressing 89998378 is not working please help me?

Try the code below at your own risk. I will not be liable for any damage this may cause to your phone.

Type the following codes on standby menu

*#0206*8378#

The Number 8378 will appear as 4 dashes on the screen. After typing you will be presented to a Test Mode menu

Select H/W Test

Select Audio Settings

Select IIS Normal (option 10) this is the normal volume for the phone. Scroll down to select Rx vol. then change level 14 to a higher value. Maximum is 30,000, I suggest setting at 5000

· You can do the same for IIS Normal2. This is the volume for Music Player
