Thank you for contacting Samsung Telecommunications America.
After reviewing your email, we understand that you are unable to decrease the volume of the incoming calls on your phone(SPH-L300).
We apologize for the inconvenience this may have caused. We do understand the importance of resolving the issue.
This is not a known issue at Samsung. However, we would try our best to assist you by providing the required information.
The support channel that you have reached has only the information regarding the technical troubleshootings of the devices. We are unable to speculate when/if the device might be available due to the fact that it might lead to confusion.
Here are a few suggestions to fix the issue :
1) Please press the volume down key at the right side of your phone in order to decrease the volume.
2) Kindly disable the Noise Reduction feature on your phone as it improves the call quality when there are any background noises.
Below are the steps to disable the Noise Reduction feature :
a. Start the Phone app.
b. Hit the menu button on the lower left side.
c. Select "Call Settings" from the menu.
d. Scroll to "Additional Settings" and select it.
e. Uncheck "Noise Reduction".
3) Please perform the Soft reset on your phone. Soft reset refreshes the internal settings of the device.
1. Turn off the handset.
2. Remove the battery and wait for 30 seconds.
3. Reinsert the battery and turn ON the device.
You can try the above steps if you have not performed them after the issue started, trying soft reset mostly resolves the issue.
4) If the issue persists, please try with the steps below which clears the cache on your phone. Wipe cache partition will delete all the temporary files and refreshes the device. These steps will not erase any data on your phone :
a. Power off the handset (for best results, remove the battery, and then put the battery back in).
b. Press and hold Volume Up key, then press and hold the Power Key.
Note: If the battery was removed from the phone, wait approximately 5 seconds before reinserting the battery or the phone may turn on prematurely.
c. Release the Power Key when the phone vibrates.
d. Release the Volume Up key when the first boot screen displays.
e. Using the Volume Keys, scroll to wipe cache partition and press the Power Key.
f. Reboot your phone.
Please perform the above mentioned steps and we are positive that the issue would be fixed.
