The only way to login I know of is using the menu button under the Feed title. When the app is launched by a third party, this menu has been replaced by a back button. That means there is no apparent way to login as the user is only presented with a sign-up form when attempting any action requiring an account.

1. Opening Stack Exchange from a browser link

step 1

2. App running - ready for user action

step 2

After pressing upvote or similar - only sign-up action possible

sign up prompt

Where do I click to login?

sign up screen

    No idea what you mean. Screenshots might help. (also, what you mean "launched by third party"? The only way I know to launch apps in my device is tapping the icon of the app I want to launch.) Sep 26, 2015 at 6:05
  • The menu is also accessible by swiping the left screen to the right (similar to Google's apps), unless I'm missing something. Meanwhile, what is the device model? AFAIK, phone layout and tablet layout has some differences (I only have phone, so I don't know about the tablet) Sep 26, 2015 at 17:09
  • @ShadowWizard I'll add some screenshots in a jiffy..

  • @AndrewT. That is true, but I didn't know (or forgot - I am using those gestures in other apps), and I am assuming other users might not either. I am using an Xperia Z2, btw. I think the main problem is that when trying to do any action as a non-logged user the only option you are presented with is sign-up, not sign-in.

  • the point is not that it is possible to sign in, but that an unassuming user has no way of knowing it when given the presented options.

    So the bug is just wording? You want it to be "Sign in" instead of "Sign up"? I thought you mean you can't log in. Sep 28, 2015 at 9:50

    No, just changing words would not fix anything, as you can see from the screenshots. You are still just presented with sign-up screens where it is not possible to login. Either provide a sign-in option at the sign-up screen or change the wording and flow. @PatrickHofman: no I was not logged in.

This will be fixed in 1.0.85.

There'll be three specific improvements:

  1. Instead of having a "Sign Up" button, it will read "Log in or register".
  2. Tapping the link will take you to the splash page with "Sign up" and "Log in" links. You can go to either, tap back, then switch to the other.
  3. If you try to sign up with an existing account, you'll now get a friendlier error: "You already have a Stack Exchange account with this email address. Would you like to log in instead?" Tapping "Log in" will use the Google or Facebook credentials you just passed in and use them to log you into your existing account.

I check this with Android Opera and with UCBrowser

And i understood about your bugs, And i tested own

When i logout the browser and log back(Opera), and click on vote up

then it shows

image 1

and then I click login or register

image 2

In here No Sign Up Option

and the i log with stack app

image 03

if i click sign up,

as you mention there is no option call Sign In

and i click on my login

then its shows


E-Mail in use

So till fix the error there is only one option to before visit to site. That is When you launch Stack app,


You have to pick Sign-Up or Sign-In

  • Thanks for checking in. FYI I did manage to log in by opening the app separately later on, but thought it should be reported anyhow.
