I upgraded my Samsung Galaxy S23Ultra a few days ago to One UI 7, or Android 15 and it has mostly been a good upgrade, but it hasn’t been perfect.
The first and most annoying, change was to the notifications when you pull down on the screen. There’s no sign of the quick settings anywhere. It turns out you have to pull down from the top right. This comment on Reddit explains how to fix it by:
- Tapping the pencil icon.
- Going into panel settings.
- Change it from Separate to Together.

The other annoyance is the three rows at the end of the quick settings panel.
- Play music / Media output
- Nearby devices / SmartThings
- Smart View / Modes
You can sort the order they appear in, but you can’t remove them. I never use them. Annoying.
The camera is fine. The UI has been changed a little. I haven’t noticed any change in picture quality yet.
I’m glad the apps drawer in the default launcher can now be scrolled vertically again. That is a feature of almost all third-party launchers, and “Home Up” used to enable it, but One UI 6 removed it years ago.
I had to delete my phone from my car’s Android Auto interface to get it to connect reliably again. I should say “reliably” with quotes because Škoda cars seem to have problems with this phone (or at least the 2020 Kamiq does), and I had to buy an Android Auto dongle to make it work. Thankfully, the new version of Android seems to work ok with the dongle.
The “do not disturb” Meeting widget is now two spaces big for no reason,
I like the UI refresh, the rounded corners are nice.
