Google-Play has this new thing called “Android Vitals” - that means there are some indicators that can flag your app as behaving badly and so get penalized in Google-Play search.

Unfortunately current light-client implementations are still very heavy in consuming data and CPU cycles.

This sadly now also means apps that do the right thing and enable/encourage light-client usage get penalized by Google-Play :-(

But there is hope on the horizon - zsfelfoldi is working on lighter clients And spoke to him at DevCon3 - things might look bright in the future as he has some ideas on how to attack the problems. But I think more people should work on this problem. I think light-clients are a critical part of the road that leads to Ethereum mass-adoption.
