Facebook comes up in the middle of my screen, but it's only about a third of the size of the whole screen. I've been researching for almost a year, and cannot find an answer to this. Even when I try to use magnify by tapping 3 times under accessibility, it only comes up to not even a half of the screen. All my other pages work fine. I cannot see well, and this is a way for me to watch my 7 children's lives. Please help!
May I have the model code of the device you are using? Also, are you using the Facebook app or a browser?
