The title says it all. The UI is okay to deal with but some of the new features are terrible. I've had my S9 for about 8 months now, and I've never had any problems with it TIL NOW. Closing the apps feature is so complicated, you have to swipe up instead of swiping left or right which is more difficult to do if you're using one hand! The End Call feature isn't there! The photos on my people edge look pixelated! And my clock is on the upper left hand corner, which is very annoying and you can't do anything in the settings to fix it! Fix thisss!!!
You could try to roll back to Oreo as some of us have. There's a how to video on youtube. Took me about 30 minutes. Also, do it from a windows computer, not Mac.
If I wanted the same look and feel as an iphone, I would have an iphone. I want my virtual BACK button reurned to the os instead of theses lines at the bottom of my screen. Before they did not take up my screen space. Instead the functions including my back button was beautifully not there until I needed it. Now they are always on and I hate it. The rest of my family have iphones and seriously considering switching due to the changes.
You can change that anytime. You can have it so that the 3 buttons remain on screen permanently or just when you want them, you can change the order, and you can change your icons in the Google theme store to whatever you want. He you like the old style look, you can do that. In fact you can use the previous style theme for Samsung and it will look how it used to, or you you can make it even more amazing than that and get an awesome colourful/entertaining/animated/fancy bling style theme just how you like it. Best thing about Samsung is the personalisation side of things to really make it yours. Out of the bad tweaks they have made that people disliked, this is one that can be resolved I hope this helps
