Once upon a time, reviews covered RF sensitivity, any websites still do that?

I work in a Faraday cage, Interventional Radiology, think lots of shielding and lead equivalents, and stream Pandora etc to a BT speaker while working, for the patients and staff.

I've tried a Note 3 and a Moto X, both of which drop the cell signal frequently, forcing me to go back to an iPhone 5s for the setup to work (I have unlimited data on Verizon and buy my phones used to keep the data plan)

Anyone have suggestions for a flagship Android phone that has very good reception I can try?
