Norton is totally useless on nokia phones, no matter what I do with the solutions from norton, it keeps turning off web protection and am I stupid? isn't that the reason we buy security, what is the point of paying for a product that doesn't work and we keep getting told it is a brand phone problem but am reading same problem on galaxy etc
What specific device and Android version are you using?
Not sure what you have tried, but look in Android Settings for any battery optimization settings. Turn off any battery optimization settings for Norton Mobile Security, NMS.
Also be sure that you have enabled the device administrator setting in NMS settings.
