I changed my sim card and when i turn on my handphone my phone was locked. The anti theft screen pop up and asked me to key in the password but the pop up screen was popping front and backward with my built in samsung handphone lock screen like crazy! I couldn't get any of the screen to stay so i can enter my keywords to unlock my anti theft lockscreen.
How to remove AVG function from my handphone? It is driving my crazy as i couldn't access to my phone due to AVG system faulty! Anyone i can talk to?
