Just bought a unlocked 640 XL from the Microsoft store. Just had a quick question because my tmobile 640 never did this
I bought the 640 XL RM -1064 model unlocked
When using data while on a phone call on the XL on tmobile I notice the signal drops to HSPA+ or even 3G.
Is this normal? My 640 always stayed on LTE during phone calls if I was using my data. The
voice calls still say HD on the phone dialer
Everything else seems to be working as usual.
