Go to the Microsoft store. And purchase a 950 XL..
I now have a 950 XL, replacing my 1520.
I have had absolutely no problems it's a wonderful phone, and no overheating or software issues as with Android and iPhone
The battery life is exceptional., dependability reception etc. across the board is perfect.. Buy this 950XL, or wait for the surface phone.
I am 😊 sticking with the windows system, it is more secure and reliable.
