Mony Mist - The smallest 4G smartphone hands-on review Introduction In a world where smartphones get bigger and bigger, one company decided to go against the grain and launch what it claims to be the smallest 4G smartphone. Meet the Mony Mint - tiny in size, but promising to fully replace your phone, while also saving you a few bucks. The phone will eventually launch with Android Pie, although our early pre-release unit was running the very dated Android Marshmallow 6.0. That won’t stop us from doing a quick review because this phone is more about the size than offering the latest and greatest Android features. And it's not like Android 9.0 is that up to date anyway.
