astro on the go cannot be install in rooted devices. most android box comes with pre-rooted. Need to check propoerly before buying it.

Samsung Homesync works on AOTG. But it is not an android box.
Not really aware on others.. but mine M8S box cant install AOTG.

Mibox can install AOTG
But Iflix canot run

With the latest firmware, Minix Neo X8-H Plus supports iflix and astro-on-the-go (no need to sideload, can install from Google Play store directly). You must not root the the Minix box, otherwise astro-on-the-go will not run though it will still install. Cheapest price if you shop around should be around RM5XX (with airmouse)

See here for Minix Neo X8-H pls update methods (not OTA)

When I got my Minix, it was the stock factory firmware (001), so I was not able to do the OTA (over the air) update as it did not detect there were updates available. I found out that the OTA method from Minix was changed and OTA only worked with firmware version 002 onwards. So I had to do the complete flash method.

Initial flashing is not so difficult, if you're not familiar, probably get someone experienced with flashing Android phones/devices to help or to advise you. Once you're on a compatible firmware version, I think OTA would be better for you assuming that your bandwidth is good enough.

FYI - On stock 001, without the 008 update, my iflix app only showed black screen although audio was working. (Thanks to bro roxx for helping me figure it out)
