I request consumer court will help me on my issue. Plz find the video as a attachment. I have bought my i phone on 20/07/2015. Not even complete a year my phone getting radio frequency noise sound from speakers while locking and unlocking, watching videos typing messages, even speaking calls also. I recorded a video at the time of getting problem. I have attached a video of my i phone 5s space grey. This problem not happend first time. On 19/11/2015 i have got the problem with my phone and i had taken my i phone to apple authorized service center in hyderabad, rsg infotech pvt. Ltd. And the service case number is s03117/h/15. He simply closed the issue by telling it is a software issue. Again with in a month i have got same problem which is more than previous problem. The service persons and apple company bluffing by selling second hand phones and also manufacturing defect phones. I have bought my i phone for ₹39000. By having the problem with hardware issue simply they telling that its a software issue. How can i get same problem again after giving to authorized apple service center. Plz replace my i phone with new one. How can i get hardware problem within a year after purchasing. I am requesting consumer forum to act seriously about the issue. I am seriously upset with the issue and the service person also not responding properly.
