Does anyone else have heat issues with the s7 ?.......After about 20 minutes of light surfing no downloads or streaming my s7 can reach 39 degrees and feels very warm to touch on the screen......I've shut all background apps down and cleared the cache files but still the heat persists ??........I upgraded from my galaxy 6 edge which never got this hot so do I have a problem with this phone ?? Or are others with this phone have these temperatures ?? Thanks for any replies.
