I have a Samsung Galaxy Note 3. Recently when I boot my phone it says Custom and then an image of an unlock padlock. My phone is not rooted. I already checked with another app. The only thing I have fone recently is try Dr.Fone in order to recover some lost videos. Other than that I have done nothing from what I read to cause this. No one else has access to my phone. How do I get rid of the custom unlock icon from the boot?
