显然这是不可能的. UC浏览器似乎总是将默认图片用于快速拨号和主屏幕.

Apparently this is not possible. UC browser seems to always use a default picture for Speed dial and Home screen.

我已经运行了RealFaviconGenerator的兼容性测试，该测试使用了几乎所有已知的技术来获得收藏夹图标:文件，PNG图标，Apple Touch图标，带有和不带有browserconfig.xml的Windows 8切片...如果UC浏览器能够接受一个图标，则该测试应该成功了，但是没有成功.完全披露:我是该网站的作者.

I have run the compatibility test of RealFaviconGenerator, which uses almost all known techniques to get a favicon: favicon.ico file, PNG icons, Apple Touch icon, Windows 8 tiles with and without browserconfig.xml... If UC browser was able to accept a favicon, the test should have succeeded but it didn't. Full disclosure: I'm the author of this site.
