Foxit MobilePDF
This program allows editing PDFs without additional installation of any components. The application is almost as good as the product from Xodo. In particular, Foxit can work with all comments and edits made by Xodo and allows to change them. This includes color selection, font and size, transparency of lines and so on. The possibilities are wide.
There are settings for appearance: scrolling modes, manual or automatic brightness adjustment, night mode, background color. Lock screen in portrait or landscape orientation is supported regardless of the system settings of the operating system itself.
To start working with the file, you can simply drag the document to the editor window or use the browser.

Such an editor is absolutely free, has many tools and a convenient but complex interface. Among the tools, there are very useful, like a magic wand, restoring brush, patch and many others.

A good set of settings makes Foxit MobilePDF a functional tool with good capabilities. The only drawback – when compared with Xodo, the speed of displaying pages in Foxit is lower, although not so much that it would cause discomfort.
