Does uninstalling apps leave any leftover files?

[AC Question]

I install a new browser on my unrooted device but I faced some crash issues and I remove it immediately.
Does this app left any files on device kitkat's system or is there any place where traces or files of this app can still remain or maybe in android all apps are "sandboxed" and run as distinct users and they don't have any access to any files created by system and in conclusion no leftover files exist on device's system after uninstallation?

Are you talking about just Uninstall, or the full sequence of Clear Cache, Clear Data, Force Stop, Uninstall?
