What do you need to be a mobile phone theme?

It is very important to consider several aspects when making a theme. Let's ignore the theme style first. 1, system version (theme compatibility is directly related to system version). 2, user habits (such as desktop wallpaper fixed and sliding). 3. The resolution of the mobile phone itself (affecting the display effect). 4. Some modules of the system (especially the default font color of the contact module will directly determine whether you need to modify it). 5. Is the navigation key a virtual machine or a physical key? Talk about online problems. 1. Some designers cooperate with outsourcing companies or individuals and only do design without writing code. 2. Subject code checking can be divided into automatic software detection and manual detection.
