Upgrading to the S7 from an S5, I notice some major feature changes like speaker and aux port on the bottom. Also, the power button is lower. There are a lot of things that will take some getting used to. I do love the sleek feel of the phone! (I'm not in love with the curved screen because I can't find a screen protector that provides the coverage I prefer.) I'm really glad the SD slot is included with the S7 (this is one of the main reasons I didn't switch to the S6). I like the front-facing camera selfie capture feature using the sensor on the back!
Overall, I am pleased with the phone!! New "toys" are always exciting!
