This has been driving me crazy for a couple years and I cannot find a solution anywhere. Help please! When I select certain icons to use I get a pop up that says "complete action using". You then have to select the action you want to use and then select "just once" or "always". Here is an example. I select Camera to use my camera and the pop up "complete action using" appears and I can select either Snapchat or Camera. I always want to use Camera so I select Camera and then select Always. Another pop up comes up saying "clear default app settings by going to Task Manager > Clear default and tapping Clear." My Note 3 does not have anything called Task Manager! Please help.
