The external speaker volume is awful on this phone. In an outdoor setting with the phone in my pocket I miss calls and texts all the time. Forget about showing someone a video in a public place or using the speaker phone in the car with the windows down as you can't hear it at all.
I found a code on another site you put in with phone's dialer and change the setting for max volume, but it doesn't seem to do anything. The max volume number changes, but there is no change in volume. I even tried putting it to zero just to make sure, but no luck.
If someone knows of anything that would work, I would love to try it.
