When entering the pattern on the lock screen, the input is displayed on the LG unit by default, allowing unauthorised persons to read the pattern and unlock the unit themselves. With the "make pattern visible" feature, which is enabled at the factory, disabling it makes the input invisible, making it difficult to see the correct pattern.
