In the Android world, it is common for large phone manufacturers to configure their products with their own versions of said operating system. This is what is known as the customization layer and it has its starting point in the HTC Sense interface developed by the HTC company in 2011 for its HTC Sensation model.
Exactly the same thing happens with Samsung. Only in this case the customization layer that Samsung applies to the Android terminals it manufactures is called ONE UI (currently in version 4.1), and as such adds improvements to the native user interface, new ways of interacting with integrated applications, among other details.
One of these details is precisely the hidden Gallery menu on Samsung Galaxy phones and tablets running ONE UI versions higher than 2.1.
The Secret Gallery Hidden Features
This secret menu known as Gallery Labs contains experimental functions generally related to the display of the elements that make up the Gallery, that is, photos and videos.
Among them are the hidden functions Filmstrip in viewer, Timelime in album, Advanced video player, Cloud video preview, Android image decoder, Show EXIF in details and others that you will discover when you make the Gallery Labs secret menu visible.
