Hello @Diti ,
It's always good to perform Wipe Cache Partition as the first step in the troubleshooting process. If that doesn't help, please report it through Samsung Members app so that the developers can take a look 😉
Have a good day!
Turn off your device > Connect your device to the PC via USB > Wait until the message that the device is being charged appears > Press and hold down the volume up and then power buttons and hold them until the device turns on > Recovery menu should appear > from there select "Wipe cache partition" (you can navigate using volume up/down buttons and confirm with a power button). 😊
