Just in case, if you are interested to access steemit through mobile, either Android or Apple, you can try @partiko. I had a great growth and user experience with it. Here’s my free install link. When you register you will get 3000 Partiko Points for sign up bonus and you can collect more along the way. You can exchange Partiko Points to Steem token as well!
