I got my MSTAR S700 at an excellent price! The phone is excellent hardware-wise, it is fast! The one and only problem I have is that my unit came with Android 5.1 with a Google Play Store preinstalled (nice) that does not work! I have already tried to get a replacement from my vendor but got a $50 credit instead. All ad about this phone that I have seen says Android 5.0 but maybe I am the only one who got version 5.1 with a broken Google Play Store. As of this feedback, I have resorted to using APTOIDE app and sometimes Amazon Underground in lieu of Play Store. I know that someday, somehow there will be a fix to my problem - but that remains to happen.
