I am facing this problem with my note 5 pro, from last month. It switches off itself randomly. And after waiting for a while I try to switch it on using the volume down and power off button -together. Sometimes it lands me in fastboot, sometimes it switches on directly. I tried uninstalling apps, but the problem didn't ease off. What should be the solution.
