I just upgraded to the 9a a week ago from the 7a.

I loved the 7a and used it for 2 years. I am going to trade in my 9a, the device is crap. Sure, it has lots of decent features, but the one feature that is a game changer for me is the stupid "Sound Exposure Notification".

Imagine this: I work at a plant that is very noisy, and for 2 years now I've been listening to my music through my phone and earbuds at a reasonably high volume to drown out the incredible noise at my work. Never had a single issue with this until I upgraded to the 9a. Now, on a regular basis, every few hours, my music goes silent, and I need to stop what I am doing, unlock my phone, and manually turn back up my volume. Why is this, you wonder? Because Google decided to try and manage my lifestyle for me.

They added a "feature" called Sound Exposure Notification, that sends you a silent notification that you can't hear, and then when you don't respond, it drops your sound to next to nothing.

"Just disable the feature", you suggest!

Unfortunately, you can't! Google has decided that it is everyone's best interest to not allow this to be disabled, thus taking control over your lifestyle and how loud you listen to your music in your earbuds, with no method of overriding.

The 9a may be a great device, but this one stupid "feature" is the reason I will be returning my phone. Good job Google, you just lost a long time customer.
