I have various videos on my Samsung Galaxy W Wonder I8150 but recently my dealer sent my phone to Samsung to have Samsung to fix a glitch ("out of phase, needed a recal" - whatver that means) as I was having only averge in call, call quality. Some settings and Play Store apps were lost as part of the fixing process but I now have everything reloaded. The only problem I notice is that some videos, that previously played in full screen mode, now only play in half screen mode or smaller. There seems no pattern as to which videos play in full screen and those that don't. Is there any way I can get videos to play in full screen mode by default ?
