Hi, We request you to register an Error Report from the Samsung Members app by attaching the system logs. Open the Samsung Members app>> Menu >> Support >> Send feedback >> Error Report >> Send system log file.

With these logs, our team could analyze the performance and errors on the device and if there is anything related to the Samsung update that you have installed recently, we would push a fix through an update.

- use vol up and down to navigate
- select Wipe Cache Partotion
- press power key to confirm
- click yes
