A while back, around when the Mi Box was first launched in stores, there was a beta program where some users could test new software updates before they reached everybody. Though the beta test program is now closed, users are now getting an early taste of Android Nougat on their devices with a new update. A few people in the Android TV subreddit have commented on the release.
Android 7.0, with security patches from February, adds new API features to the Mi Box such as picture-in-picture and DVR capabilities in Live Channels. There’s no word if this includes the firmware necessary to play video from over-the-air broadcasts.
Redditors have noted a few issues, and it’s likely these issues will be fixed before the release is final and pushed to all users.
