I really like the pure Android experience so for me, the Nexus 5 would be my choice. Yes, I own a few BLU's (office writes Android apps so I get to see a lot of phones.) The LG G4 is what I'm carrying today which has a great camera.
I have Metropcs in Boston. Love the price and I am able to get signal everywhere, however my phone is freezing up after the latest software update. I also have my wife's, she is leaving Sprint to join Metropcs. We both are looking for a phone with a great camera (for my wife the iPhone 6 would be great but at $650 is not a price we can afford right), good RAM, 16gb with SD Card or at least 32 gb and screen size from 4.5 to 6 at the most (I have read about the Nexus 5, Blu XL, Moto X Pure Edition and many more.)
As for me, I would love to continue using Android, but I am looking to spend between $200 and $400 each phone. Can you guys help me?
