I see this notice translated into my local language - and it literally says to install the FreeBitco.in app. It's weird that it appears even though I've blocked pop-ups in browser options - I don't believe it's malware because I get no other pop-ups on any other site.
Hmmm, that seems different from mine.
Try checking and see where it leads you to. If it simply asks you to add the page to the home screen (should prompt), then it's legit.
Anything else like an APK or Play Store is definitely sus.
I configured the new phone (Samsung) to my dad and he wanted the freebitco.in shortcut in Home and that was the only way to let it put in the Homepage, I never saw it by the way and I trusted the procedure. It doesn't seem to download anything, it seems like some sort of wrapper of the website, but in the previous phone (Xiaomi) he owned, there wasn't such a feature, it just placed a shortcut to the browser Chrome.
It seems legit by the way.
