finger sensor gesture

[a10suser]

The finger sensor gesture is not working on my phone after the oneuicore3 update. It works for a while after I restart but doesn't last

Well does the fingerprint unlock 🔑 work?, if it does then try factory reset if you can or head to Samsung center if your phone's in warranty
