Emphasis is being put on the front camera since the mid-2010s, where front cameras have reached resolutions as high as typical rear cameras, such as the 2015 LG G4 (8 megapixels), Sony Xperia C5 Ultra (13 megapixels), and 2016 Sony Xperia XA Ultra (16 megapixels, optically stabilized). The 2015 LG V10 brought a dual front camera system where the second has a wider angle for group photography. Samsung implemented a front-camera sweep panorama ("panorama selfie") feature since the Galaxy Note 4 to extend the field of view.
