Hello everyone,
Every time I end a call, this annoying notification pops up, giving me the time of the call and asking me if I want to save it or not... It's so annoying and I don't know how to remove it... Can you please help me?
I'm using extra, but before I use it, the notification came anyways, just in a different way (didn't said it was from operator and was just the screen a bit darker with the notification).

Please help,
Much appreciated :)
