When going through the login flow for Open eBooks, there is no description or labeling. Open eBooks has two login options, FirstBook and Clever, and they are both equal partners. The login screen the user gets in the Android flow right now loads u/p login fields directly after accepting the EULA, with a button for Clever at the bottom. It both ignores the FirstBook branding and privileges it in terms of user flow.
I am inclined to force an additional screen, like we do on iOS, but it will delay us further. We could also just add copy that says "If your school uses FirstBook, log in below. If your school uses Clever, tap the blue button further down."
