苹果新系统出现信号图标缺失的情况，可能是由于系统更新过程中出现问题导致的。建议重启设备并检查网络连接是否正常，如果问题依然存在，可以尝试联系苹果技术支持寻求帮助。
In an attempt to simplify the interface and enhance user experience, Apple may have changed or adjusted the signal icon in their latest iOS 17 update. If you're still having trouble with the missing signal icon after updating your device, you can try scrolling through the screen or checking out the Settings menu for the "Signal" option to see if your signal strength is accurate. If you continue to encounter issues, it might be best to seek assistance from Apple Support or consult relevant documentation for more information.
