Plex 6.0 makes it possible to play video files stored on your Android phone or tablet
If you have Plex installed on your Android smartphones or tablet, you will be able to open video files stored on the device's storage or SD card with the new player. Files like MP4, MKV, AVI, WMV and more can now be played without a server. Furthermore, you can even open a video file in another app and choose to play it in Plex if that's what you want.
Plex 6.0 for Android is being rolled out to compatible devices starting today. The new version should be up for grabs in the Google Play. A public beta of local video file playback is available for download as well.
