No analytics data even after being turned on

Hello anjali15__,

Are you looking to view certain information about your device? Sharing analytics means that Apple can access non-personal device information, as outlined at Legal - Device Analytics & Privacy - Apple.

iPhone Analytics may include details about hardware and operating system specifications, performance statistics, and data about how you use your devices and applications. This information is used to help Apple improve and develop its products and services. None of the collected information identifies you personally. Personal data is not logged at all, is subject to privacy preserving techniques such as differential privacy, or is removed from any reports before they’re sent to Apple. You can review this information on your iOS device by going to Settings > Privacy & Security > Analytics & Improvements and tapping Analytics Data.

Do you see anything listed? And how long ago did you begin sharing information?

Thanks!
