I wish I could say the same! Since this newest update my phone does nothing beyond the initial Samsung loading screen(s). Soon as it boots up, and gets to the wallpaper that is my lock screen, nothing appears. It will flicker slightly once, as if it was reset and then, a couple of minutes after starting it, up pops an error message that "One UI Home has stopped" or "keeps stopping", since the message will continue to pop up every couple of minutes.
I am still able to get to my apps and the device still works as a cell phone. Have not noticed anything else wrong, but this alone is ludicrous. Why pay top-dollar for a high-end piece of gadgetry such as this, only to be forced to find work-arounds for sub-par performance following the latest update?!
Turn the device off.
Press and hold the Bixby / Power key past the model name screen appearing on the screen.
When SAMSUNG appears on the screen, release the Bixby / Power key.
Immediately after releasing the Power key, press and hold the Volume down key.
Continue to hold the Volume down key until the device finishes restarting.When Safe mode appears in the bottom left corner of the screen, release the Volume down key.
While in Safe mode, you can now uninstall apps that are causing a problem.
This is what I did and it stopped after that
1. put the App Smart things to sleep
2. There are other background apps which are running
1. go to Device care > Battery
2. click on background usage limits and turn it on
3. put unused apps to sleep
4. some you apps you can put to deep sleep too
after this the battery was not dying like it was before
