Samsung Mobile — Mobile restarting / Hanging Problem

Address: New Delhi, Delhi

Hi, I have purchased this Samsung Galaxy notre 2 (GT-N7100) on 20/08/2014 from Delhi. It works properly only 7-8 months. Now there was some issue of restarting and out of network problem and the device restart occasionally for which i have submitted the handset SAMSUNG CARE - ADVANCED TECHNOLOGIES, JHARSA ROAD, GURGAON. They told me it takes around 3-4 days as there is a problem in main board which has to be replaced. I don't know what they did, they had returned the handset after replacing the main board. The handset works properly almost two weeks, after that there is similiar problem of restarting as well as hanging ( THE PHONE GET HANG, NO DISPLAY, NO SOUND, ONLY BLUE NOTIFICATION LIGHT IS BLINKING) Finally need to re-insert the battery to work it again. Most of time the handset becomes out of network silently ( without any notification-Signal bars shows full network). When try to make any call, it shows" Network Not Registered". For your kind info, I have replaced the SIM also but the problem not resolved. I WANT TO KNOW THAT HOW COULD THE HANDSET REPEAT THE SAME PROBLEM IF THE MAIN BOARD IS REPLACED. I AM SURE THAT NOTHING HAD BEEN DONE IN THE DEVICE ( ONLY SOFTWARE UPDATE/RESET). I HAVE EXTENDED THE WARRANTY PACK ALSO. AS SAMSUNG IS THE GLOBAL REPUTED BRAND IN ELECTRONICS, SO WHAT IS THE USE OF PURCHASING THE SAMSUNG PREMIUM PHONE IF YOU ARE NOT ABLE TO RESOLVE THE ISSUE.
