System update
Update is usually meant to optimize the system's compatibility and stability for the new released phone. It can optimize the existing problems or system bugs. Some updates will add new features or adjust the current design to optimize the operating experience. The update will not reduce the performance of the phone, nor will it delete the original data in the phone. So we suggest you update your phone to the latest version. You can go to Settings>System update to check for the new version.
