US Cellular, like its larger competitors Verizon and AT&T, pre-installed proprietary applications (My US Cellular, Navigator, Backup Assistant). On Android 4.4, these apps were merely annoying. On Lollipop, which prioritized fluid animations and cohesive design, these legacy carrier apps stuck out like sore thumbs. They retained the old, dark Holo styling, creating a jarring visual disconnect between the modern OS and the carrier’s utility apps.
