I am using M31 mobile since 1.5 years. Suddenly it stopped working and automatic restart continously. When I checked in servicing center they had taken Rs.120 for inspection and they reply me the motherboard crashed. Its cost is Rs.7000. Another two servicing center I had visited and there also same reply motherboard crashed and they told maximum persons having this motherboard problem in this model. For cofirmation I had visited one servicing shop and they also told, this model having manufacturing defect and maximum persons having this problem. I have maild to samsung, they replied your warranty period has completed so u can replace this motherboard with chargeable basic. Its not possible to change motherboard within 1.5 years with Rs.7000.
So please resolve this issue.
