How to change the font thickness of Meizu mobile phone

Do you mean to add system display fonts (such as desktop display fonts and SMS fonts)? The current solution seems to be realized only by modifying the registry. I hope I can help you. The picture has been uploaded. I wonder if that's what you mean. The way to modify the registry is to open the optimization wizard, system tools, registry editing, enter items with the machine, select software, enter Meizu, select SMS, there is an smsfontsize in it, and double-click to modify the key value. One thing to note is that you have to restart the machine once after the modification to see the effect. If you want to modify other font sizes, you can use the same method to query key value modifications, especially those key values and registry key names that are meaningful. You can understand it literally.
