Would rma it either bad board or battery cause battery can cause email to over heat.
Would rma it if happens all the time if still under warranty.
If warranty ran out ya might find parts on ifixit.com or eBay or online somewhere.
do you use it while environment is hotter than 35°C?
did it happen while charging the battery?
did you root it?
no, thermal paste is not used for this kind of hardware. If it´s overheating, the chip or the battery is getting to hot itself by defect or hot environment or using the wrong charger, if it happens while charging.
Some tablet's and phones can over heat while charing and running intesive tasks . Only happens when cpu ram at heavy load while charging . Is just giving yang a warning I'd unplug it or stop your running tasks till fininsisted charging. Myou Brad new Samsung Galaxy s2 did the same thing but game me battery heat warning while it was charging and updating 2 Oscar versions
So more then likEly he was using it heavily and charging at the same time . If happening repeatedlyrics and still under manufacture or square trade or type of extended warranty then would just file a claim
If it only happened once when you had a heavy load on the ram and cpu in the tablet while it was charging no.
If it's happening all the time then probably something wrong with it.and would really rma it.
And got a thermal warning on this brand new Samsung Galaxy tab s2 8 inch got yesterd a year while it was charging but it installed 2 new Oscar versions and was on heavy load while in air conditioned room . Haven't happened since but was first charge and takes a lot of ram cpu and ssd load to install the Oscar updates
