Is it necessary to update the mobile phone system for the new mobile phone?

General system updates will improve the performance of mobile phones, enhance the ability to protect personal privacy and data security, and provide you with more fresh functions. If you use Huawei mobile phone, I suggest you upgrade your mobile phone to the latest version in time. You can go to Settings, search for system updates/software updates, check the updates, and choose whether to upgrade as needed. If not, the current system can still be used normally.

Tip: It is recommended that you upgrade in WLAN environment. Online upgrade will not clear user data, but in order to protect your data security, it is recommended that you back up your own data before upgrading (third-party applications such as QQ and WeChat need to be backed up separately).
