Hi, My daughter has a Galaxy s4 which is second hand. See decided today she wanted to change the lockscreen from a pattern to a code. I did this for her and entered the code and confirmed it. The first time the screen was locked it is saying the pass code is incorrect. I am 100% sure I am using the correct code that was set as I did it myself. Is this an issue anyone has had and if so how can I get it unlocked without factory resetting the phone.
