It's messenger, what more can there really be said. But I tell it not the go some notifications and it still does. No matter how I settled up the settings. So I deleted it and if I get private message I just grab my phone.
My Samsung 6 constantly warns me that there is a security risk while Messenger App is active. I keep putting it on and taking it off when I receive a request from a friend. I have seen 3 of my friends accounts hacked and someone tried to run a scam on all 3 by saying that I have won something and they need my info to claim the prize. Beware of strange messages.
I kept getting messages from others, that I usually access on my laptop, but while my wife was in the hospital and I only had my tablet, I thought I'd give it a try. I quickly found out I didn't like the way it ran on the tablet so tried to uninstall it, only to find out it can't be done! Now I have something I will almost never use clogging up memory from my OS.
