Why doesn't the audio show up in my iOS 11 screen recording?

I have the beta version of iOS 11 and have been using the screen recording function. However, the audio from what I'm doing on my phone doesn't always show up on the final video. I'm thinking it is just because of the length. I recorded a video about a minute long to test, but the video I tried to record is around 20 minutes. Is this on purpose or is it a glitch? And is there a way I can fix it?

Is my Iphone blacklisted?

So please don't judge me on this question, I'm just a little confused. I'm trying to sell my Verizon iphone 6s plus to someone who has metro pcs. I've checked two different sites to check my ESN and they said the blacklist status is clean. One buyer asked for my ESN and told me it was blacklisted and its basically worth $50. Mind you, I bought my iphone from another person who had it with Verizon and all I did was switch my Cricket sim card into the iphone and it worked perfectly fine. If it was blacklisted, would I have been able to still do that? I've been using the phone since Feb 2017. I can call, text, have LTE data. I just wanna double check that if I sell it to someone with METRO PCS they can use it. I don't wanna rip someone off.
