I uninstall app store and other apps that has to do with my email. But when I install it back now is giving me trouble entering my email address and giving me an error message that I enter my password incorrect. How can I fix this problem because my app store wont load up either and when I click on it, its telling me Authentication is required. You need to sign into your Google Account. I tried signing my google account on my phone and like I said it says incorrect password. My third or fourth question is my internet. it doesnt function at all. I cant log onto it if i dont have wifi at home. It should work either or.
