Hi Everyone,

Device Name : GT-I9082
Android Version : 4.2.2(Stock ROM)
Baseband Version : I9082LUBUBMK1
Kernel Version : 3.0.31-1329016 se.infra@RO301-08 #1 Mon Sep 9 22:12:54 KST 2013
Build Number : JDQ39.I9082XXUBMI1

Problem:
I bought Samsung galaxy grand duos I9082L from Abu Dhabi and i am using it in india. from last 3 years. I did not have any problem till now but unfortunately from last one week my mobile was unable to reach when it was idle(i.e. Mobile is turned on and battery is full, signal is good but still unable to reach) . I use the operator Airtel and when i switch off the phone and turn it on then again the sim receive incoming calls. Apart from that when i make some outgoing calls to anyone then immediately at the same moment within 5 or 10 minutes i can able to get incoming calls. There is no problem with outgoing and internet but i am getting irritated with incoming as many of my friends and family unable to reach me on time.

Steps taken:
1. I have rooted my device and installed stock rom on my device with indian firmware so build number and kernel version changed but baseband version did not change . Does Baseband version need to be changed to India ?
2.I have changed the sim but still issue persists

Can someone suggest a solution for this problem. Any valuable suggestion appreciated !!

Thanks,
Praveen
