I've been trying to install snapchat and shazam all day, and the progress bar is only the preliminary one, like it shows no progress with actually downloading the app, and eventually i just end up with a triangle with a ! inside that says it failed to download the app, but when i look on google play it says the app was downloaded. idk what to do, and i actually found that it was also non-responsive with my instagram the other day. I have a gmail account, and I have successfully downloaded things before, so that is why I am wondering what I need to do or am doing wrong. thank you~
