I purchased a brand new Samsung Galaxy S5 Saturday April 4th. I had no problems with any of my apps. Well, last night snapchat updated, and now its not working. It will not login, its like my 4g network freezes up. I have re-started the phone, I have uninstalled, and re installed the app. I even had a friend try to login and it does nothing. What is a fix for this? Can anyone help me?
