not sure what causing it but On my Note 5, after each call, i get a popup that reads "just call with" and then their contact name. theres a picture of a cartoon man on a phone, my call duration for the month and if my data is on, theres a random adchoices ad that is starting to really annoy me. my incoming call screen also changed to a black screen with a bouncing green answer button. my incoming text messages trigger a popup too that has the same ad as the end call popup. can anyone tell me how to find and disable the app that is causing all these ads?
