A moderator within Samsung’s community forum responded to the reports, outlining the next steps. Affected users are being asked to submit detailed bug reports, including log files, through the Samsung Members app. This data will allow the development team to analyze the root cause of the performance issues.
Initial troubleshooting steps, such as clearing the cache, have not resolved the problems. Instead, the underlying code of the firmware will need to be reviewed and optimized, sammyfans reports.
