Ratings and reviews

What a great application this is convinced me to use and uninstall other media players from my phone. Easy to download, easy to execute and easy to not burdon cell phone using. I like it and enjoying its easy features.

ST Player is good video player in it you can easily watch any format video with lot of options like forward, backward and pinch to zoom. It also support dual Audio and subtitles.

Over all a good App. KEEP IT UP ST player Team.. Ads are annoying, as they come up just before playing the video. Folders organizer is good, color scheme also Interactive. Volume control with swipe up and down and brightness control is one of good option like other modern players. Speed control is good feature..
