I detest my phone so much that I want to break it.
It's the worst thing I've ever experienced and I've got tinnitus in the bargain, it's the worst.
Quite ironic that in the headset it goes perfectly well for the phone to go from minimum volume to maximum volume of 2sec, in locked position lying in the pocket. However, if I connect it to the stereo in the car, it is difficult to get over half the volume even without a lot of warnings that you can damage your ears. Pretty funny, right? Because it is so nice to unconsciously raise the volume when it is at greatest risk for it.
Now I'm sitting here with my tinituss and wish I had never bought the phone.
Unfortunately, you are not rich so you can buy a new phone anyway.
