FV Player's latest update (6.1.3) brings a couple of new settings that affect mobile devices, along with improved playlist subtitles and better control of how MPEG-DASH streams switch quality.
New Mobile Settings
There is a whole new section in Settings > FV Player > Setup tab called Mobile Settings.
It contains two brand new features:
Use native fullscreen on mobile
When turned on, this option will force player to load the native fullscreen on all mobile devices. This will result to losing all the FV Player's extra features like pop-ups, ads, speed buttons, AB loop or subtitles, but it will provide a faster and more stable interface for some of the devices. This option is actually turned on automatically for mobiles and tablets with older versions of OS (Android 4.4 or lower and iOS below 7).
