Obviously Galaxy S7. Anything else. My last 3 iPhones have SUCKED with wifi. My 5s drops wifi at least 20 times a day at home. I ran speed test and I get anywhere from 3-25 Mbps with the 5a while my laptop gets 80-90. My brother in law can over with his android and got 80-90. I've done restore multiple times as well as network resets. This has been a problem with the 5c, 5s, and 6 plus. My wife has a 6s and doesn't have quite as many wifi issues but I'm done with Apple.
