I have been using T-Mobile Lumia 640 LTE for the last 4 days. Overall great phone. I also own the Lumia 920. One issue, which I am not sure is an issue, is with the audio quality Bluetooth audio streaming on 640.
I stream audio from my XBox Music app to my Bluetooth speaker. There is no issue with the pairing and subsequent audio streaming. The issue I noticed the audio quality is very sub par when I use Lumia 640 compared to Bluetooth audio streaming from Lumia 920 or any other phone (iPhone 6, in my case). I had to increase the volume quite high on the speaker to hear the audio.
NOTE: In all my tests, the volume on the Windows Phone is set to Level 30 (Max - 30/30) for Media + Apps when paired with the Bluetooth speaker. FYI Lumia 920 is on Denim with 8.1 Update 1.
Anybody else noticed this issue? Could this be an issue with Bluetooth 4.0? Is this an issue with Windows 8.1 Update 2 (Also known as GDR2) on Lumia 640 ?
