It would be better if you cite all the possible application that can cause cryptojacking in android phones to spread awareness among our people.
I have read a recent article that League of Legends an PC online game had spreaded cryptojacking in most of the pc platform. If I am not mistaken the issue haven been solved tho I am not that updated when it comes to pc gaming lol.
Another thing is please avoid rooting your android phones as it may alter the operating system which can cause a complete access to everything making it vulnerable an unknown types of files installed.
