I have purchased xiaomi Redmi Note 3 phone three months ago. now, phone has stuck up on headphones mode even after I plugged out my headphones. I went to service center in Rajkot but there they arrogantly told me that this problem does not cove up in warranty. Phone was never fallen down. it does not have any physical damage though they told me that it is physical damage and will not cover up in warranty.
