Just bought it a week ago and now dust is going inside the phone in front of rear camera lens, which is affecting my experience with the phone and also affecting the camera quality. What should I do now.
Sorry to hear this. I would recommend taking your phone to a service point - you can use our locator service to find a care center near you or if you bought your phone in Europe, you can simply take it to the retailer or operator you bought it from.
Hope your issue gets resolved soon!
Have a nice day,
