Samsung s10 horrible phone

I purchased an S10 a few months ago. The engine constantly overheats with stock software. I have had the phone wiped so many times but it is a cheap phone being sold as a high end premium device. Well I will certainly look to iPhone next. They are hassle free. Also android auto does it work with Samsung, I see thousands of posts online but no fix from Samsung. Why should be continue to support this brand if there are so many other good alternatives?
