As with any type of first aid for any electronic, an easy way to fix most problems is really just turning it on and off. Because your Chromecast is running multiple programs at once, one of its processes can get stuck and slow down your entire device. When you restart your Chromecast, you essentially stop all internal processes and give its system a chance to boot up from scratch. In some cases, a simple restart can resolve any Chromecast issues, even if you don’t know what these are exactly.
If the restart doesn’t work, you can take it to the next level by performing a factory reset. A factory reset addresses various software issues that can occur after extended use of your Chromecast, such as corrupted files or software updates. By performing a factory reset, you essentially return your Chromecast to how you first unboxed it. However, just so you know, you will need to take time to set your Chromecast up again.
When all else doesn’t work, you can contact Google Support to help you troubleshoot your lagging Chromecast. In a perfect world, every electronic will work seamlessly, straight out of the box. Unfortunately, factory issues or defective problems can arise, which can’t be fixed by remote software updates. If this is truly the case, please check your warranty status to know if your Chromecast is still eligible for free repair or replacement.
