#One UI 5.1

Back then, Samsung's mobile user interface called "TouchWiz" used to be a con for those considering a Samsung phone. [caption id="attachment_330808" align="alignnone" width="480"] Touchwiz On The Galaxy S6[/caption] Filled with a ton of bloatware, goofy animations and sounds, and lacking long-term software support, many wished Samsung phones had a cleaner and smoother software experience to match their hardware. To be blunt, many wished Samsung phones had Stock Android instead. It was simple, intuitive, and bloat-free — making the overall phone experience smooth and stutter-free (which was still hard to find on many Android phones back then, to be fair).

With an emphasis on one-hand-ability, One UI was a drastic overhaul of Samsung's mobile software experience introduced in November 2018 on top of Android 9 Pie. It was released on the Galaxy S8, Note 8, S9, and Note 9 as an update and came preinstalled on the Galaxy S10 series, Galaxy A series, and the OG Galaxy Fold as One UI 1.1. One UI brought a more streamlined, more consistent, and arguably much smoother user experience that made us all forget about Samsung's TouchWiz woes.
