I've been with Android for the last three years after leaving the iPhone due to me feeling it wasn't adaptable enough and the OS was getting stale. Lately, I had missed iOS and went back to the 6s Plus. Overall, I'm very happy. I like how snappy it's been and the battery life is excellent. I'm having two weird problems which are kind of annoying. The first being that TouchID doesn't work all the time. I'm forced to enter the passcode often. It's not because the home button is dirty either. It just flat out stops working sometimes. The second issue I have is I've noticed when I'm coming off Bluetooth, that my speakers/sound puts out this metallic clanging sound (buzzing sound) and the only way to fix it is to reset the phone. Two small issues, but annoying. I'm surprised Apple has let that slide. They are usually on top of that type of thing. However, I'm still very happy and don't regret switching back. Hopefully these issues get resolved with a software update.
