I already heard about that news that coin.ph is also accepting etherium but i also heard but for now not all coin.ph wallet have an etherium but some other coin.ph user is already have etherium
It is maybe a beta version(?) so not all user had this feature. I had mine updated at this moment and I also had eth wallet as a feature. I don't know if the phone brand is one of the reason but I think it is not definitely the main problem. By the way I am using Vivo s5 lite for reference.
