Need some help here. I keep getting this error/alert message on my S4 recently. Security Information An application attempted to access system on your device without authorisation. This attept has been blocked. Deleting applications obtained from unauthorized sources may improve security. There is a button "View Apps" to click and it basically list all the apps in my phone but doesn't tell me which one is causing the security alert. I have tried to delete all recently installed applications but still this alert message keeps popping up. Any ideas what's wrong? Thanks in advance.
