how to change default video player in gallery on s6 nougat

At the default zoom level, despite having an 18 percent larger screen, you really don't get 18 percent more app content from the larger device. To show the practical effects of this, in the gallery above we compare a 5.1-inch Android device (a Galaxy S6) to a 6-inch device (the Nexus 6).

This alleviates one of my pet peeves with 'phablet' sized Android devices, which is that bigger Android phones usually don't let you see more at once, they just make everything bigger. In Nougat, a new 'Display Size' setting gives users an option to control the scale of the entire interface, rather than being stuck with the scale level set by the OEM. Buried in Settings -> Display -> Display size, this setting lets you 'zoom in' and make everything bigger or you can 'zoom out' and make things smaller. If you're a fan of high information density and want to see more on your device, setting the scale to 'small' is a killer feature. Typically you'd see just as much app on a 5-inch phone as you would on a 6-inch phone, but on the 6-inch phone everything would be bigger. The scale of Android's interface is resolution and screen size independent, with size of the interface set by the manufacturer through a setting called 'ro.sf.lcd_density.' Manufacturers typically tuned this setting so that all phones, regardless of screen size, showed roughly the same amount of information. A 5.7-inch phone with the display scale set to 'small' versus the a standard scale 5.1-inch phone.
