This is the message I am looking to get rid of:
I learned that you can get rid of this message on other Androids by going to the app that it generated from and clicking "disable notifications". However, I have no idea where to find the app that causes this message and I also can't long-press the message to see where it comes from. So any other answers to solve this problem? Or do any of you guys know what app cause these sorts of messages to pop up on your homescreen?
