 * Check whether your issue/feature is already fixed/implemented
+* Check if the issue still exists in the latest release/beta version
 * If you are an Android/Java developer, you are always welcome to fix/implement an issue/a feature yourself. PRs welcome!

 * Please only add *one* issue at a time. Do not put multiple issues into one thread.

 ## Bug Fixing
 * If you want to help NewPipe to become free of bugs (this is our utopic goal for NewPipe), you can send us an email to tnp@newpipe.schabi.org to let me know that you intend to help. We'll send you further instructions. You may, on request, register at our [Sentry](https://sentry.schabi.org) instance (see section "Crash reporting" for more information.

 * Try to figure out yourself why builds on our CI fail.
 * Make sure your PR is up-to-date with the rest of the code. Often, a simple click on "Update branch" will do the job, but if not, you are asked to merge the master branch manually and resolve the problems on your own. That will make the maintainers' jobs way easier.
