Here is a synopsis from the S7 topic posting I recently made: Welp, the last two days have been telling with the S7 so far. I think I made a huge mistake getting a Metro device and getting it unlocked. The signal quality has been tough to deal with, idk if it's my network or just the phone. Yesterday, calls with work were being wonky. Had to step out to just get a consistent signal which was weak. At work, dropped to HSPA+ and took like 2 minutes for a call to connect. At home, the phone cuts in and out under "cellular preferred" option for Wifi Calling. Very frustrated with having to use a home phone to get calls through, especially for work. So I have signal quality issues I guess. Will try the iPhone out today to see if it's the signal or the difference in iOS vs Touchwiz/Galaxy. Which Android devices have the best radios? I am looking at maybe ZTE Axon Pro, OP3, Nexus 6P, or something else below $500. Any input is appreciated. Thanks.
