Last month, Nokia released a new firmware update for its X-series music phone, Nokia X3. The new version 21.0.004 can be easily downloaded from Nokia Software Update (NSU) or via. Over-The-Air. Although Nokia X3 has support for User Data Preservation (UDP), you should backup all your data before updating this device. This update may not be available for all the product codes.

The official changelog for this update is not available yet but it comes with two important fixes and improvements – improved battery charging notification and enhanced ring/alert tones. We will update this post as soon as we get the complete changelog, screenshots and videos of this firmware update. If you find something new or if you have some screenshots or videos of this firmware update, please share with us.
