There are many factors that cause white apples, and the common reasons are:
The conflict between the software and the system causes the system to fail to load normally.
There are too many startup items, and the conflict between software will also cause white apples.
The system could not start calling the component. (It may be due to user's mistake in deleting, modifying and setting permissions incorrectly. )

Generally speaking, the user used an application that modified the system, which led to a conflict between the system and the application, thus producing a white apple. Common software formats in iOS devices are PXl, iPA, DEB, etc. Among them, iPA is the official software format designated by Apple, and its stability and security are guaranteed. Generally speaking, installing iPA files will not cause white apples.
However, PXL and DEB files need higher system permissions, which will modify the system files and destroy the stability of the system, so the problem of white apples often occurs.
Therefore, users are advised to use PXL and DEB software as little as possible. Reduce equipment problems.
