Mgo is not available worldwide, probably only the US and maybe Canada, plus the UK and Ireland on Roku. And:
The Ultraflix app is available since early november. Not two years as might be understood by your wording. And strangely enough when I check Google play, it states more than 500 installs, not 100. Weird ... Must be a typo. Surely not deliberate by any chance ?
Yes, when you install Ultraflix, you can't help but admit that it is actually real. A shocking discovery that a scam like NTEK has a working app to stream 4k, and even has 4k content that streams on Android devices. No ? LOL Needs some tweeking agreed, but so what. Netflix wasn't what it is now right from the start. Or was it ?
As of this morning, Google Play Store gives Ultraflix a range of installs, 500 - 1000. You wrote 100 installs on Saturday, so it has installed more than 400 additional. GO NTEK.
