Consistent *Minor* Problems with my 6P

I've posted a couple times about my phone and got mostly negative feedback.. Heh.

I have a 128gb in Frost (color is irrelevant, but felt appropriate..) and I have had nothing but 'minor' problems from the start. This is technically my third 6P, the first two having physical little defects (scratches) upon opening the box. Now that I have a physically perfect phone, I've experienced consistent trouble with the following:

1. Camera. The camera does not open as quickly from either double clicking the lock button and from swiping up on the lock screen. If it does happen to open, there is a 2-5 second delay (occasionally longer) and I can't take photos until the photo album icon loads the most recent photo taken. I noticed the 'lag' is reduced immensely when I delete all the photos in my album, but what's the point in that when I have a 128gb phone? >( I take a LOT of random photos, and ran into my storage being full on my iPhone 6 64gb due to apps, documents, music, photos, etc., which is why I opted for a 128gb phone this time around.

2. Mic. Whenever I make a video call, or someone calls me requesting video, the mic will ALWAYS shut off after a few minutes, without fail. I've tested this with Oovoo, Skype, Facebook Video, and Google Hangouts.

I have restored the phone a couple times, and it hasn't resolved the issue. Before contacting customer service I wanted to see if anyone else had a problem as well.

Thanks in advance, everyone!
