The 2016 model of the Samsung J5 (which has physical touch-buttons) recently got the “Samsung One UI Home” update made available in Google Play. This will replace its TouchWiz launcher.
1) Will it slow down the phone (like system updates) since it’s primarily geared for higher end phones?
2) Will it work altogether, since the images shown in Google Play have the virtual buttons that higher end Samsung phones come with. Does that mean the launcher isn't compatible with physical buttons?
