I came across an obviously fake application claiming to be Astroneer on the Google Play store.
Title: Astroneer: New Adventure
Developer: EVGENUY
Contact: evgen.chuyashenko@gmail.com
All the reviews say the app doesn't open, but has a "start" button. Very likely a virus as well as containing ads to make them money.
I reported all of their apps to Google, but they don't have a label for fake app or virus. I hope someone at System Era sees this and can try to get it removed.
