Facebook Messenger is like a frickin virus. It takes over your SMS, phone, contacts, and they force you to download it just so you can view your facebook messages. Chat heads pop up automatically, dominating your phone.
I still do not use messenger, have not downloaded it, etc. All my android products ( phone, Tablets, pc) I use on the Desktop version and I am able to use messenger via the web browser ( Chrome or Puffin).
Was really surprised about the AVG permissions, my husband uses this and is usually quite savvy about downloading apps that require dodgy permissions. he refuses to even use facebook never mind the messenger.
What about all the people you asked to be your friend who ignored or deleted your request? Facebook keeps track of that. Go to facebook.com/friends/requests(Opens in a new window) for a list of the people who hate you. Or maybe they just don't check Facebook that much. Probably both.
In June 2012, Facebook removed all existing email addresses from user profiles, and added a new @facebook.com email address. Facebook claimed this was part of adding a "new setting that gives people the choice to decide which addresses they want to show on their timelines". However, this setting was redundant to the existing "Only Me" privacy setting which was already available to hide addresses from timelines. Users complained the change was unnecessary, they did not want an @facebook.com email address, and they did not receive adequate notification their profiles had been changed. The change in email address was synchronized to phones due to a software bug, causing existing email addresses details to be deleted. The facebook.com email service was retired in February 2014. 2b1af7f3a8
