Why can't the weather forecast of Samsung mobile phone be updated?

If the mobile phone can't upgrade the system through FOTA, please check whether there is the following prompt: 1. If the phone prompts you to install the latest version, it means that there is no higher version to update at present. 2. If the system prompts "Daily download limit is reached", it is because the time-sharing update method is adopted to ensure that the server can bear it. Please try again later. Otherwise, the mobile phone has an update version prompt, but it cannot be upgraded, or there is an interruption or installation failure during the upgrade process. Suggestion: 1. Please check whether the mobile phone is set to the current time. 2. Whether the mobile phone has enough power or storage space (storage space is recommended to be at least 1GB). 3. If the mobile phone system update prompts that the registration failed, it may be a network problem. It is recommended to try again another day or connect to a stable wireless network/mobile data network (the firmware may be large, so it is recommended to connect to WLAN to upgrade). 4. If the equipment still can't be upgraded or the upgrade fails, so the machine can't be used at present, it is recommended that you take the purchase invoice, maintenance card and machine to Samsung Service Center to check and update the system. Note: If the mobile phone system update prompts that the device has been modified, it may be because the mobile phone has been refreshed. It is recommended to contact Samsung Service Center for handling.
