It happens on my other Samsung phones as well. Sometimes when the screen is touched with wet hands or greasy. What I do is turn the screen off then wipe the screen, turn the screen on again and back to normal
If you have a tempered glass on your screen or if you had a software update recently installed, these could be possible factors. If it's the latter, wiping cache partition or dialing *#2663# (to update SP FW) may help.
You may also try to enter Safe Mode (or if possible, do a factory reset). If the issue still persists despite doing either (or both), it's possible that the issue is at hardware level.
