Proper materials was a simplification, proper thermals would have been a better wording.
I am only unhappy with it after the software updates and corresponding performance loss. Can I return my phone a year after purchase when I found out what the cause of the performance loss was? Could I have months after, when A12 was released? Will I get my money back? Doesn't look very likely...
Selling it is only passing the problem on to another person which I wouldn't do.
The last paragraph is that Genshin Impact, Antutu, Geekbench and other popular games or benchmarking apps have no limitations on prime core usage. Why are some apps allowed full hardware usage and some aren't?
And don't think it's because of thermals, the phone is below 40C, cooler attached, Genshin uses prime core, Aether doesn't.
