I have just got a Samsung Galaxy s3 on Virgin, and I am unable to download apps from the Play store. I get error code 403 - both when trying via wifi and by mobile internet. I have cleared out my caches, removed and re-added google account, made new google accounts, factory resets. To no avail. I am getting in a really stressed and bad mood because of it, and all the solutions people have said about online don't work for me. Is there anything I can do?
