[Resolved]  Samsung India — motherboard problem

Address:

Kolkata, West Bengal, 700054

My samsung j2 has just passed 1 year. Suddenly i saw the ph is not working. I went to the nearest authorized service center.
Firstly i was told i need to change the battery. I then changed the battery rs 1300.
Still the phone was not working. When i was calling i could hear the voice of the other person but he cannot hear my voice.
Secondly they suggested it is a mike problem. Then they changed the mike rs 500 approx.
For 1 day the phone was working, next day the same problem, i went to the service center they checked the ph. Asked me to wait for 2 hours.
Thirdly they told mother board problem.
Till this time i had sent roughly rs 2000.
Please help and suggest me how to make the phone workable.
