Galaxy S4, sign-in doesn't work with correct password (even after reseting it), emailed sign-in link, or connecting my google account (which was something I didn't want to do). Says uknown error, contact dropbox support. If I do the incorrect password it tells me so.  Can't find any info. I can sign in on other devices, but I need to be able to sign in on my phone.

After updating to the newest version of Dropbox Android app, I can no longer sign in to Dropbox on my Samsung tablet. I get the following error:

 

Sign-in failed, unknown error, please contact customer support.

 

I have unlinked all devices except one. Any help is appreciated!

 

Thank you, LMD

    Hey there LMDLMD, I hope you're having a good day so far!

     

    So I can have a better idea of the issue that you're having, please let me know the following:

    • Which version of the app do you have installed? eg. 184.2.8
    • What OS version is your device running?
    • Do you get the same error when signing into your account via the website?

    Let me know and we'll take it from there!

    I am also having the same issue after the last update of the Dropbox app for Android via Google Play Store. I have unistalled it, signed out of my google account, restarted my tablet, reinstalled Dropbox, signed back in to the play store and then Dropbox all to no avail. Still receive the same "unknown failed to sign in error". Even though everytime I try to sign in to Dropbox I receive an email notifing me of the sign in via my tablet. I have no problem signing into Dropbox via Google Chrome though.
