Go to Settings > About Phone > Software Update. The F55 5G benefits significantly from firmware updates that address error codes and improve stability.
Power off, then hold Volume Up + Power + Bixby buttons simultaneously until the Samsung logo appears. Select "Wipe Cache Partition" using volume keys. This is especially helpful for F55 5G devices experiencing persistent errors.
