authentication is required when I try having an access to the google play store I am not able to install my favourite games such as ZOMBIES KILLER 3D. Whenever i ha ve tried installing this games the pla store send me a message and that is "authentication is required you need to sign in your google account"
I am kindly requesting you solving my problem.
Try to clear the data for the Play Store app.
Navigate to Settings >> Apps >> Search for "Play Store"
Then Click "Clear Data"
Hope that helps!!
