I bought xiaomi mi 4i 3 months ago from flipkart with one year warranty. As from starting i have been suffering from"over heating" issue, AND ALSO HAVE WORDS WITH COMPANY EXECUTIVE, they suggested me sometimes to wipe caches and sometime to reset the phone or to wipe the whole data, but all go in vain.few days ago i got a call from my father, and as i accept the call the phone starts heating infinitely and the screen damaged its own during call and i could not able to even disconnect that call and use tha touch again.and i went to customer care at janak puri, delhi, they rejected my phone by saying this issue is not covered in warranty.
