After upgrade, every phone call displays an ad?

Question

Running on an LG Stylus 3 on Android 7.0 security patch date Oct. 1, 2017.



After a recent upgrade every time I make a call, after hanging up I see a notice



"Quickly record a Voice memo"
@ Writen an email



and then an ad. I don't think this is an app, I think this was done to me by the update. But if there is any way to get rid of it, I would like to know.



I don't want to be offered a choice to record a voice memo, when I'm done with a call I want back to the main screen. And I certainly don't want to see an ad.



Is this google or some third party? Is there any way for me to tell who is benefitting/originating from a given ad?

Answer

I forgot I had added recording software. Going into safemode definitely established that it was not Android itself. Then the question was how to find the app. I don't have a great answer, but scanning through all the apps showed me that I had added one, and denying it privileges fixed the problem.



As a side-note, Android desperately needs a way to identify a page or notification and see who is responsible for it.
