Phone heating up

[dubeysoham]

My phone is heating up with minimal usage.  Also while playing pubg my phone got warmed up like anything and the phone switched off nd starting restarting on its own for a couple of minutes . Finally turned on after 5 mins . Whats wrong with this device?

From your original post it looked like you were still experiencing reboot issues, my apologies for the miscommunication. What firmware are you running? If it's stable enough to update the FW, try getting an automatic update by going to Settings > System > System update.  You can also do a manual download for your region, the guide on how to is here https://www.asus.com/us/support/FAQ/1009748/, and the download link is here https://www.asus.com/us/Phone/ZenFone-6-ZS630KL/HelpDesk_Download/. 

If that doesn't help, then the advice to contact your repair center still stands.

Just to be sure, make a couple of runs with a benchmark like antutu to stress the phone. If you have a phone with a "restarting issue" then it will likely be triggered by the heat. If nothing happens, then it was hopefully a one time thing.
