Q: Not able to access App Store in I phone 6 9.2 ,

Hello divasuji,

It sounds as though, while you're able to access the Updates page of the App Store, the other pages aren't loading correctly. This is typically the result of an issue with your iPhone's ability to properly communicate with the iTunes Store. The steps outlined in the article linked below can help restore your iPhone's ability to properly connect to the iTunes and App Stores.

1. Make sure that your date, time, and time zone are correct. Tap Settings > General > Date & Time. Time Zone might list another city in your time zone.
2. Make sure that your iOS software is up to date. Tap Settings > General > Software Update to check for updates. You can also connect your iOS device to iTunes and click Check for Update on your device's Summary page.
3. Check and verify that you're in range of a Wi-Fi router or base station. If you're using cellular service, make sure that cellular data is turned on from Settings > Cellular. If you're connected to cellular data, larger items might not download. You might need to connect to Wi-Fi to download apps, videos, and podcasts.
4. Make sure that you have an active Internet connection. Check your device's user guide for help with Internet connection.
5. Check to see if other devices, such as portable computers, are able to connect to the Wi-Fi network and access the Internet.
6. Reset your Wi-Fi router by turning it off and then on again.
