Hello Friends, Myself Vishal and I am from India. I am new to this forum and a huge fan of android. I have samsung galaxy grand duos model name GT-I9082 having android 4.2.2 running in it. I have several querries regarding the android and I hope all of you will help. My question is my phone displays two IMEI nos. when I dialled *#06#(code for getting imei no. of device) on it. However there is only single number on the purchase invoice given by the vendor. I supposed this is due to the Galaxy grand is dual sim phone. Now my question is that which no. should I consider and mention while specifying warranty claims, new software updates and giving the hardware details to someone. I mean should I specify only one of them(if so then which one), or both. Also one more doubt is that the imei no. is given in the format like xxxxxxxxxx/01 what is the meaning & purpose of slash(/) and 01 here. Please help me to resolve my querries.
