So far I can't get "Ok Google" to work with the screen off. I set it up right and have the options turned on that need to be. It only works when the screen is on. I want it to wake the device like my other devices.
The scrubber doesn't always work in Google Music for me. It rarely does. I don't use that option much but still.
And that's about it FOR NOW. Having a switch on the side for noise is a very nice addition. I'm not used to that on my Android devices. I usually only have that when I use my iPhone's. If OnePlus can keep this device updated they are going to be a great option to stick with. The ability to change and customize this device WITHOUT rooting is a huge plus for me. Especially since I don't usually root my devices. Getting a 128GB smartphone with the latest processor and 6GB of ram for what I paid is a huge pro.
In short, the good outweighs the bad. By a long shot.
