one ui crashing, lagging, freezing

about a week ago my note 9 started acting up.  When I close an app or switch between apps I get a black screen then it says Samsung one ui home stopped working and I can't move or delete any of my apps from the home screen.  The apps themselves work fine.  Is there a fix for this?

Re: one ui crashing, lagging, freezing

. I would recommend wiping the cache partition. The system cache partition stores temporary system data. It's supposed to allow the system to access apps more quickly and efficiently, but sometimes things get cluttered and outdated, so a periodic cache clearing can help make the system run more smoothly. Give these steps a try:

  1. •    Turn off the device.
  2. •    Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. •    When the Android logo displays, release all three keys.
  4. •    An 'Installing system update' message will show for 30 - 60 seconds before the Android system recovery menu options appear.
  5. •    Press the Volume down key several times to highlight wipe cache partition.
  6. •    Press Power key to select.
  7. •    Press the Volume down key to highlight yes, them and press the Power key to select.
  8. •    When the wipe cache partition is complete, Reboot system now is highlighted.
  9. •    Press the Power key to restart the device.
