weird issue with my signal when using BT on a call

[beman39]

so today I was driving in my car and my BT connected to my 950XL and I get a phone call and then my signal drops from LTE to 3g and then to 4G and back down to 3g and then when I hang up it goes back to LTE and all is good, so I call my GF and low and behold my signal drops to 3G and then I hang up and boom it goes back to LTE so I keep watching it and it stays at LTE for long time there... so my GF calls me back and BOOM it drops down to 3g! so I know its got to be some sort of interference from the BT!! anyone else experiencing this? I would suggest everyone keep an eye out for this!

That's how calls work. Voice is always transmitted though 3G/HSPA+ while data can use LTE. Unless your phone and network provider both support VoLTE this is normal.

but I never noticed this happening on my L1520...

I'm typing this on my 1520 with WM10 and it has always done that...you may have not noticed it.
