I recently had to record a quick testimonial video and got a good Rode VideoMicro at my disposal. It also had a nice cable and worked perfectly on an iPhone, great combination, good results, I could see from previous work.
But I have no iPhone.
I have to admit I never bought an iPhone before, and I think I never will. That's free for everyone to chose, I'm happy with my uncle Sammy stuff - I bought 'm since they launched, and I was happy.
So I stuck to Android.
And to be honest: I love iPads, and MacBooks.
And I also love to use Windows 10.
I'm not into a "this is better than" discussion, it's a free world, you can do whatever you please. I love good tools and great software. So I use a lot of everything.
I currently use a Samsung S9+, I think it's a very good phone, and it does great stuff when recording video.
For that testimonial I needed to shoot, I had about 4m of distance between my phone and the person.
"Use a microphone" was the first thing that came to mind.
I picked up the Rode VideoMicro (which is a great microphone, it really is).
Easy as pie you would guess: plug in the whole shebang and off you go:
Open camera, hit video and record.
In short: That doesn't fly.
On a Samsung Galaxy S9+, things do work, but you have to take a couple of things into account to record video with an external microphone
First, the audio jack takes TRRS on a Samsung S9+ to record.
So make sure your Rode (or other microphone) has TRRS, there is an optional cable available.
Second, you have to tell your phone it has to select external audio from an external microphone.
And that’s the really tricky one: You can search in the standard Camera software... there is no option to do so.
No can do.
So how do you record video on a Samsung S9+ with an external microphone?
1) Install the Open Camera app (it's free, no ads).
Look it up in the Play store, and select the right one ("Open Camera"... that simple).
2) Make sure you have an external microphone, and get a signal splitter.
As Mike H (Thank you for the feedback) put in the comments, you should get a signal splitter, as shown here below.
And to be on the safe side, check if the audio jack contact on your signal splitter has TRRS.
I bought a lavalier microphone recently (an audio-technica) to do some testing, and that comes with a sort of 'dongle' that also splits audio in and audio out. Using that practical dongle, you can connect audio in and out.
And you can also see the difference between TRRS and TRS clear on the picture. The signal splitter (above) has TRRS:
3) You need to fiddle around in Open Camera's settings to make sure you check these two options.
So, go to 'gear' and select 'Video Settings'.
First, you have to indicate to record audio when recording video. Don't forget that.
Second, tell Open Camera to use an external microphone if there is one present:
Now, that's all there is to it.
It’s no rocket science, it's pretty easy.
Since I didn't find any simple practical explanation online, other than video's telling you can do it (I know you can) I wrote things down as simple as possible how to do it.
This should help you to figure out how to record video with an external microphone on a Samsung S9+.
So that’s how you get things done when you need to record video with an external microphone on a Samsung S9+
