Facebook Update android Problems
Edit: this seems to be an issue that Facebook recognize. It's a problem with the Facebook app, and also not a generalised Play Store concern.
This is what worked for me at least.
- Settings > Applications > All > Google Play Shop, Clear information and also Clear cache
- Settings > Applications > All > Google Play Provider > Manage space, Clear all data as well as Clear cache
It does not injured if you restart your phone before you attempt upgrading facebook once again. And, the set up was SLOW. Simply a minimum of 4-5 mins. However, it did work. Otherwise try to uninstall it, or just await a fix.
