This is the best benchmark I've ever seen. I got 18.181 without having my S20+ on max performance, but on max performance I got a shy of 17.425. 10/10 would recommend.

Thanks for the positive review and for the 5 stars. 🙂👍 Try to test your S20+ on multithreaded mode as well. 😉

It does what it says it does. Can't really complain tbh. Could use some more threads but honestly even with 4 threads my phone finished VERY quickly.

Thnx 4 your review and the 5 stars. One of my later plans is to make the 8-thread version. But first I will do the iOS version.
