Samsung s8+
 

No camera display causes and solutions

Hello nkechi :)

I don't know if this is what you are asking for but if there is no camera symbol on your lock screen of the S8+ try this:

Go to your homescreen and swipe down from the top of you phone. Then go on the settings icon. Select lockscreen and security. Find "App shorcuts" and click on it. Then select Right Short Cut and turn it on. Make sure you select the camera from the shown list. Then the camera icon should be back on your lockscreen.
