To update the software, navigate to Settings > Software Update > Download and Install. Follow the prompts to complete the update. Ensure your device is connected to Wi-Fi and has sufficient battery life before starting the update process.
Your device may run slow due to insufficient storage space, too many background apps, or outdated software. Clear cache, uninstall unnecessary apps, and ensure your software is up to date to improve performance.
