Key stopped working after upgrade to Android 5.0.1
My phone is Samsung Galaxy S4 GT-19506, I upgraded latest Android version 5.0.1 and after that Key stucks on it's load screen. Key has latest version updated and phone has been restarted several times. Everything else works fine. My Google Nexus tablet had Lollipop upgrade several weeks ago and I run same version of key there and it's working fine. Please solve this Galaxy ASAP!
