Samsung One UI

For years, Samsung has been facing severe criticism because of its software on the Android phones. Samsung makes the best smartphones. There is no doubt that Samsung has managed to remain the industry leader when it comes to handsets. However, Same is not the case when it comes to the software.

Samsung’s UI, which was called the TouchWiz UI, was famous for being the UI filled with the maximum junk and bloatware. Samsung used to add a lot of applications by default that the UI used to become a burden for the phone. There was absolutely no option to disable or delete those applications.

Samsung overhauled the TouchWiz UI and named it as Samsung Experience UI. By this time, Samsung had added the options to disable some of those inbuilt applications. The Samsung Experience UI was a big change, but it failed to satisfy the Samsung users once again.

Now Samsung is all set to roll out the Android Pie for its flagship devices released in 2018. With the Android Pie, Samsung is looking forward to refreshing its UI once again. Samsung is all set to say goodbye to the Samsung Experience UI and welcome the One UI. 

Samsung One UI looks much better, neat and clean, and bloatware free as compared to the Samsung Experience UI. The UI is bringing a whole new design for the icons, for the application drawer, and new interfaces for all the stock applications. The rounded icons look much better now.
