I am able to get past the log in screen. There were no accounts associated with the device so I tried to sign in with my Google account and it won't accept my password ( which I know is correct) so I created a brand new email and password through the ACER account page and after completing the sign up, it prompts me to log in again. SAME ISSUE. It says my password of the new account is invalid. I opened Amazon apps and created a new account on my phone and then tried to log in and guess what?? It says invalid email and/or password too. Is this a software issue? I have factory reset the device and still with the same problem.
