@jvk: While connected to a stable Wi-Fi router, please head to Settings > About phone > Software information, and tap on Google Play system update to search for any available updates here. Alternatively, head to Settings > Biometrics and security > Google Play system update. If an update isn't available then don't worry, as your phone will automatically download and install the latest update when it becomes available.
