Steps to reproduce
1. From another phone, make a call to the Nexus 5 device. 
2. On the Nexus 5 device, use the hardware Volume Up or Down button to change the ringer volume.

Expected Results
The ringer can be adjusted with the hardware Volume Up and Down buttons.

Actual Results
The first time the hardware Volume Up or Down button is pressed, the volume goes to mute. Pressing the hardware Volume Up or Down buttons does not take the volume out of mute state.

When the call is coming, press volume up, the ringtone will become louder. But if you press volume down, device will enter mute status.

Fail rate:5/5

I think this behavior has been implemented as expected. I've always seen the callscreen behave like this. I just checked 2.1, it reproduces there.

QA wanted to check 1.4 on Buri to see if it was there. If so, no need to check further. If not, please check Flame 1.4.

I see behavior on comment 2 but NOT behavior on comment 0 with Buri v1.4.

With incoming call ringing, device responds to volume UP as expected, but as soon as volume DOWN is pressed once it mutes the ring and cannot be unmuted for the duration of the incoming ringing. I do NOT see what's being described on comment 0 which is ring mutes regardless of what I press - this is NOT observed.

Note setting tracking flag because I'm not sure if the behavior I'm seeing is what the reporter was seeing.

Tested on:
Device: Buri 1.4

User Agent: Mozilla/5.0 (Mobile; rv:30.0) Gecko/30.0 Firefox/30.0

Note that there are no newer v1.4 Buri builds on PVT website. This is the newest.

I think the behavior seen is the one in comment 2. On comment 2, it happened on the same build and was reproduced 5 times.

Hence, this is not a Nexus 5 issue. We'll need some UX input to confirm it the behavior is the one we expect.

Hi 

I think the rule here is that if the phone is ringing, tapping all the hardware keys (volume up/ down and power key) will switch it to mute mode. The behavior in comment 2 is not expected. Because if the volume up key can really adjust ringtone at that moment, then the volume down should work the same way too and then users have no way to enter mute mode with this rule. So I'd still go with my suggestion here (all hardware keys -> mute). Thanks!
