The facebook app works perfectly! I don't know what's wrong with you all, This app is fine. But I don't know about the scrolling down though...Anyways, works fine. Btw, Don't do system update anyway. -_-
Go to your apps and on the right side click on the box in the middle (the one with stripes) click update apps and Facebook should come up. Click on update app button. It is orange. It will update for you.
So far Facebook has froze up on me at least a handful of times on my brand new kindle which led to the back of my kindle getting very warm, would like to know what is going on. I don't have a lot of time to sit and talk on the phone I am afraid it is going to lead to more issues can't be good for it to get that warm I couldn't even turn the kindle off it was stuck on the Facebook notification pop up for a good hour! Anyone else have this happen?
