well if your using your 4g surf online it will heat up its normal. it just mean youre phone is pushing itself more thus heating up. it happends when you use your 4g and (in this case) surf the web or use a big app like clash of clans or sim city. its normal and you dont have to worry but i do suggest trying not to heat it up so much.
