Why is my phone overheating and restarts Randomly ?

[AC Question]

Hey guys .. i have a note 4 for over a year now.. it gets uncomfortably hot and then restarts randomly .. i checked some articles about overheating issues and i tried putting it in the safe mood and observing it for an hour.. i even watched some youtube videos and it just got warm .. can it be some games because i have like 16 games ? and there are some software updates i haven't installled .. should i try installing them or just deleting games would do it for by the way my sister has a note 4 too and she has alot of apps and doesn't have aproblem . should i contact the market i bought it from i am still in warranty ?

Welcome to Android Central! Are you saying that it gets that hot and restarts even in Safe Mode, or that it doesn't get quite that warm in Safe Mode?

How is the cell signal strength? Poor signal can lead to increased CPU workload and heat generation.
