A couple of Xiaomi users have experienced problems with slow response time of the app, which is usually related to network issues. Because of these issues Xiaomi users generally complain of no notifications, browser not working etc. on their device.
According to the makers, the probable reason for the issues with Internet connection, is the wrong settings being used. The users are advised to ensure that they have proper Internet settings installed.
Please go to Settings and follow the following steps to improve the functionality of Xiaomi devices with Airtel connection:
1.) Select SIM card and mobile networks
2.) Select mobile network (Airtel)
3.) Select Access Point names (APNs)
4.) Select Mobile Office (default is usually Airtel Live) and you are good to go!
