I have Samsung Galaxy Xcover 3 Value Edition SM-G389F
RF Cal: 20161113
HW Rev: MP 0.100
I have problem with sound quality from this phone. Sounds like it use very low bitrate GSM codec, because sound on other side is muffled and unintelligible.
I have tried to call with the same sim card from other phone - sound is much better.
Please, tell me if someone knows, how to check what codec GSM uses?
And if possible how to change it or disable low bitrate one.
Thank you in advance.
