I have found that when using speakerphone in a less-than-quiet area the volume of the speaker seems to increase if you hold the phone in the following manner:
Hold the phone upside down with the screen facing towards you.
Use your pinky and ring finger and the pad of your palm to hold the bottom of the phone and use the rest of your hand (which should be hanging off of the end of the phone) to create a cup that cups the speaker and reflects the soundwave towards you.
Obviously the actual amplitude of the sound generated by the speaker is not changed but the volume seems to be louder due to the echo created by redirecting the sound waves.
Also note that the sound will be a bit
more distorted than the standard volume. But a little distortion may be better than the alternative.
Please let me know if this helps anyone i know i have found it handy.
