Seriously, what was Samsung thinking? I have loved every UI I've seen on a Galaxy... Until this point. It's always been angular, clean, and centered. That's what I like. Clean. Orderly. Aesthetically pleasing. With One UI, I feel like I've mistakenly turned on senior mode and everything is all edgeless safety notifications, huge round, ugly text, and giant blank areas wasting space... This needs to be revised.
Oh come on, at least give us our messaging colors and backgrounds back!!! This is terrible, I bought an Android because I wanted an Android, not a crApple iPhone.
You could try installing third party launchers to make it more oreo like nova and try good lock 2019 to get some features back or just flash back using Odin it's what I did there are plenty of tutorials on YouTube to show you how just make sure everything is backed up because it wipes your device browsers bookmarks are something you should back up and game data which can be a pain but it's doable.
I had the same problem. I didn't even want my Note 8 anymore. I found the (How To) video on YouTube. I followed the steps and rolled back to Oreo with no problem at all. I can now enjoy the phone I originally purchased and not that ***** Samsung is trying to force on everyone. Honestly makes me never want to purchase another Samsung device..
You can change things so it acts a bit differently with good lock and it's add ons and with a custom launcher or try and flash old android version using oden lots of videos for these things on YouTube.
There is the way to disable One UI without root or bootloader unlock
you need to:
1) Enable menu for programmers (go to info, tap build nr 7 times)
2) Enable USB debugging
3) connect your PC, download Android Studio or Android Toolkit to get adb (on Linux you can simply sudo apt install adb)
4) issue commands:
adb shell 'pm disable-user --user 0 com.sec.android.gallery3d' //disable Samsung Gallery adb shell 'pm disable-user --user 0 com.samsung.android.app.notes' //disable Notes app adb shell 'pm disable-user --user 0 com.samsung.android.scloud' //disable Samsung Cloud adb shell 'pm disable-user --user 0 com.samsung.android.knox.analytics.uploader' // disable surveillance adb shell 'pm disable-user --user 0 com.microsoft.office.officehubrow' // disable MS Office apps ads adb shell 'pm disable-user --user 0 com.sec.android.app.launcher' //probably our main target - OneUI adb shell 'pm disable-user --user 0 com.samsung.android.smartswitchassistant' // smart switch assistant
adb shell 'pm list packages -f'
to get full list of the packages.
That way I was able to disable One UI in favor of other launchers, disable bloatware apps, and my Task Switcher was returned to Vanilla Android one. Works much better and faster. Modifications are done as a setting for current user (not globally) so you'll not void your warranty that way. You can undo any of these by similar 'pm-enable' command or factory reset.
