Hello! I bought the Sony c5ultra dual phone a week before but I m facing so much heating problem with it. The phone gets heated even if I m using only Whatsapp ! I have double checked about the background running apps but they were closed. I am not a hard core game player that mean phone heating issue is not the gaming and neither I use WiFi or mobile net all the time . Please provide some solution so that I don't regret my decision of purchasing this phone. Thank you.
