My S7 gets a little warm with heavy use but other than that it stays cool. I have a fast charger that works if you have a Qualcomm processor and it gets a little warm when I use that but not enough to be concerned. I'm just glad that I didn't get the S7 Note and I almost did!
Have a brand new S7 which always seems to be warm/hot especially when have wifi on. Not pushing the phone by any extreme. Have read other posts saying this will stop after a few days??? Anyone experienced similar?
