Maybe someone can explain to me the distinction between the Samsung-generated notification to login to Facebook, vs the usual Facebook app login? I assume what's happening is that the S4 has some native/embedded facebook functionality distinct from the official standalone Facebook app. I generally ignore it and just use the app. But it keeps re-notifying me. So occasionally I'll go ahead and click the Samsung/Facebook prompt, and it takes me to some sort of limited web browser (it's not Chrome, and hitting the menu button to bring up a context menu has no effect). In that browser window it asks for my facebook login info, and also mentions that I should consider downloading the facebook app - meaning that it clearly can't see that I already have it installed. And even if I do sign in via this embedded Samsung/Facebook, eventually it forgets and asks me to sign in again. Annoying! I assume this is just a thing I caused to happen by not signing into either Samsung or Facebook when the phone was originally powered up. But I'm curious to know if anyone can explain for this embedded version of facebook: - how it works? - if it is in any way better than the standalone app? - if I can/should disable it in favor of the standalone app? TIA.
