How to fix after a flight the volume is real low on the Samsung Rugby III?

After a flight on commercial airlines the volume is barely audible at max. Eventually it returns to normal. (never determined the time). Today it has been 3hrs and still low. I expect tomorrow it will return to normal. I replaced a Rugby that had this issue with another SM-B780A and this has the same issues.



Are you pertaining to ring volume? If so, while in standby mode, simply press the volume up key to increase volume.
