My Facebook friend gets notifications whenever I post or like something on someone else's profile. This is kind of creepy to me. I liked a mans photo and she immediately came back with ( so in so is nice looking huh) I don't want her to see what I like or comment to other people she is not even friends with them. I know she uses an android phone. How do I keep her from seeing what I do on Facebook besides deleting her.
You cannot control this. Your friends may see what you have liked & commented on their news feed or in their real time ticker. If necessary, block the people, who you want to be unaware of your activities.
The only thing you can do is to never like or comment on posts/pictures that have their visibility set to "Public" or "Friends of friends".
If you only like/comment posts that have their visibility set as friends, then your nosy friend A will not be able to see your activity with your friend B's content ( expect if A and B happen to be friends).
