Troubleshooting Facebook Authentication Failed on Samsung Galaxy S3

galaxy s3 facebook failedAfter thousands of email I’ve read regarding Samsung Galaxy S3 problems I thought I’ve seen it all. But today, a friend of mine showed me his phone asking how to resolve a somewhat easy problem–Facebook Authentication Failed.

When I first heard of the problem, I thought it was just a login error, and advised him to double check on his login credentials, although he was positive his email and password were correct. Since we were really close, I asked for his password and tried to login to his account using my laptop—It went through. I tried logging in using his Galaxy S3, “Authentication Failed!” That’s when I knew there was a problem.


The first thing that entered my mind after having confirmed there was a problem was the internet. Since he was using mobile data, I switched to WiFi and connected to my home network; the connection was fine.

I tried to login to his account but it still returned the same error. I double-check the connection, then tried to log it again—still the same. Therefore, it wasn’t a connection problem.

Clearing Cache & Data

Since there were no other services that were affected by the error, I knew it was just one of the Facebook App errors users may encounter. So, I immediately decided to go on clearing both the app’s cache and data.

Settings => Application Manager => All tab => Facebook => Clear Cache, then Clear Data.

I tried to login and it went through. I thought that was the solution, it wasn’t. I know that because after I was able to login, I logged out and tried logging in again and the problem returned.  At that point, there was nothing else to do but reinstall the app.

Reinstalling Facebook

Having acquired the permission to reinstall the app, I immediately uninstalled it. I went to the Play Store and downloaded / installed the recent version. After the installation I rebooted the phone and tried logging in—it went through. Then I logged out and logged in again, there was no problem. I did the process about 10 times or more just to confirm everything was fine; the problem didn’t occur.

Basically, the Facebook Authentication Failed error may be caused by the obsolete version of the app, although I’m not really sure about it since I didn’t know what version of the Facebook app my friend used at that time.

Bottom Line

At the end, I was able to fix the problem but I didn’t know what caused it. I’m not sure if the same problem happens on iOS as well but it seems like older versions may have some problems with Android Jelly Bean. If ever you encounter the same problem, try updating the app or reinstall it like what I did.

  1. Same Problem That I have now…
    Is anyone can help if how to activate account settings on fb?
    It’s always AUTHENTICATION FAILED Everytime I try to open it…?

  2. Ever since I have deactivated my fb account, my fb is constantly under Authentication Failed. I can login to my mobile phone (samsung note 3) but cannot login on my PC. Even when I am able to login to my mobile phone, I am not allowed to operate any of the setting on my phone, such as the Security etc. Can anyone please help?

  3. I have the same problem.
    1. I used to open FB on android mobile thru website, instead of FB app. While FB website on android was active, I often simultaneously accessed FB thru laptop. Both worked well.
    2. During this last 6 months, I often deactivaed FB for some reasons. But, I regularly checked the FB account (as no 1 above) once every 1 or 2 weeks, then deactivated again
    3. few weeks ago, I could not access FB from website, neither from Android mobil nor laptop. Everytime I log in, it’s always back to login page without any notification (no notifications of the wrong password, etc), as if I have not logged in.
    4. The login picture is still on the web, but I cannot tap it, and it always returns to no. 3 above
    5. I then installed FB app on android mobile. and I can log in
    6. BUT … I cannot enter all the options under the “account setting”, “Activity log”, “privacy shortcut”, and “mobile data” of the FB app.
    When I try to tab those options, it’s always rejected get the notification “AUTHENTICATION FAILED”, . FB automatically logout and I have to repeat writing password

    I had tried to do clear cache as well as uninstalled FB app. Both didn’t work

    But I hadn’t tried CLEAR DATA, for I am so worried if it will delete my FB account

    Could you please help me .. what should I do? :'(
