Having trouble updating facebook.. It will download and then tries to install and says ERROR not properly signed... Any known fix?
Wound up completely un installing all facebook files, data and everything. Then pulled facebook app from the newest room I could find on the web and putting it back into system app and rebooting.then go to accounts and sync..added back to sync and then the app showed back up on phone. After that, the download for the update worked.. Idk. Lol
