Its the Exynos processor Guys, famously hot running, under performing and battery hungry compared to the Snapdragon equivalent. Which is why people are disappointed that the new Note 20 has the same bad processor.
its strange pubg G use to do the same on the s10 and I wouldn't play pubg on it, now months later it plays effortless and doesn't overheat and I've the exynos model, could improve like another post has said here or maybe it won't, Id still not risk it and give it back with the 14 day return policy, Im Truely disgusted I didnt leave my s10 back for several other reasons
i had the s9 and didnt have any bother, i don't use my phone much, calls, texts social media and pics of my daughter. just found it very strange that it was nearly burning the hand off me, il give it a few days to see how it goes. cheers for the info guys.
