I'm on day 3 of using my Galaxy S7 temporary replacement for my recalled Note 7. It's also auctioning as a possible replacement for my 6S Plus on my original line that I planned to trade in after I get my Note 7 phablet back. The crazy thing is that my potentially explosive Note 7 ran cool as a cucumber. It was cool during the set up period and cool filming videos and cool during fast charging. It only got hot once when I downloaded and tried to run Neko Atsume while the phone was experiencing another glitch I didn't know about until later. My Galaxy S7 is a hot potato. It's hot off the charger. It got hot during setup. It got very hot casting home videos to the Samsung Smart TV we have. It was hot when I was outside texting my husband. Granted I was in some sunlight but I can text from an iPhone SE or 6S Plus under the same conditions and not feel the phone generating its own heat along with whatever it picks up from the sun. I didn't have my Note 7 long enough but I don't recall it heating up when I used it in the sun to take pictures. It's always running a bit warm. Is this normal for the S7? I looked on AT&T's site and did see a one star review talking about a lady's S7 being another hot potato. I'm definitely returning this particular unit so I can get my Note 7 back. But I was trying to determine what "normal" is for an S7 since I was considering getting one for my other line. I like the size of it. It can switch back and forth with my SE as my pocket phone when I need a waterproof phone and wear shorts or jeans with sufficient pocket depth.
