I don't think that is true. If you run the Nginx web server on Linux for example, with a case sensitive file system, I'm pretty sure that the files you serve will also by default have case sensitive URLs. And probably it'd be the same with Apache on Linux with a case sensitive file system.
What? Case-sensitivity is the presumed default everywhere.
I said there is no such problem in a browser, meaning, the url is displayed correctly, not converted to lower case, meaning, the problem is only in the app, and I'm suggesting: "Who needs a phone app for this anyway?"
