Well I think a lot of you know minergate over here. They made an mobile miner app for Android!
Tested it on my s7 edge (exynos europe version) with monero (xmr) mining and found 2 shares in 1m and 11 secs
hashrate about 20H/s the same as 1 cpu core of a modern pc on xmr
this is 8 threads on a phone. Definetly not worth it to mine on such an expensive phone but just thought it was funny to see how far technology has actually come!
