Hi! I have changed my sim card on my phone, so my phone has been locked. I entered the correct password. However, it still show that the phone is locked. I tried all ways to unlock the screen but the phone looks like freezing. It is really inconvenient. I highly regret to have this mobile antivirus on my phone. Please some help. It is totally urgent for me, I can't do anything without my phone.
