hello everyone, I own iPhone 6+ for two years now. I noticed that the earpiece volume is bit low, but after I made a call with my wife's 6s I understood that my 6+'s volume is very low. I made small research and I saw that it's a common issue with 6 and 6+ models and that the way to solve it is by disabling the noise cancellation. I tried it without avail. Do you familiar with any other solution? Thanks!
