I have constant pop up ads on my phone and they get worse as time goes on. They told me at the store it was from an app that was downloaded and i need to find it and delete it. I deleted all the apps just to be sure but with no luck. This has been going on since i bought the phone. When i asked them again about it they didnt know how to fix it. I have other friends with the S7 having similar problems too. Now I'm having other issues. Sometimes my autocorrect doesnt work, it no longer syncs or finds my email and it wont let me reconnect it. I am also having issues with it randomly deciding not to connect to the Internet, even though i am on wifi most of the time it will lose connection and say retry later. Im about ready to throw this phone away and cancel my contract. Its so frustrating for the price that we pay for the phones and the service. I never had any of these issues until i switched from my S5 to the S7
