While the Nokia E63's video player was a significant innovation, it had some limitations and drawbacks:
CorePlayer is a legendary multimedia application known for its incredibly fast, hardware-accelerated decoding engine.
If you are trying to install CorePlayer or SmartMovie .sis files today, you may encounter certificate expired errors. You can fix this by changing your Nokia E63's system date back to 2009–2011 in the settings menu, or by applying a custom software hack (like Norton/HelloOX) to disable Symbian certificate checks permanently.
