I checked off the box on "Noise Suppression" and it doesn't do anything at all. The sound is still choppy over speakerphone. I've searched up on the forum, and so far the threads that come up are from 2012 or early 2013, but I assume that T-Mobile has made new radio/baseband settings since then.
My question is, what is the most stable radio/baseband to use on the T989 to get rid of the speakerphone problem, or is this problem a design flaw since the speaker is near the microphone?
All help is appreciated.
