user21522: I'm interested in using a smartphone as an expensive tool to capture speech audio and video. Perhaps equipped with a tripod, add-on wide-angle lens and wireless microphone for the speaker.
Anyone with experience in doing something like this willing to share your experiences?
Are the add-on wide-angle lenses any good for this? I have a Galaxy S8. What about video capture software? Is the built-in camera app ok for this purpose or should I use a 3rd party app?
Any experiences with non-bluetooth wireless mics? I'm worried about BT range and other connectivity issues.

user19655: Were I work we used an iPhone 7 and a Samsung S8+ for an experimental web series  to capture video. The result was awesome, specially when you use stuff like the DJI Osmo Mobile 2 Smartphone Gimbal. (The series is not yet released, will updated when the editing is finished)
At first we used Bluetooth microphones but there is a lot of issues with the range and sound quality. We used the Sennheiser ew 112-p and recorded the audio on a Tascam DR-05 . This is a little expensive, an alternative will be to use another cellphone and record the audio there with a wired microphone. 
No need for a third party app, specially on the Samsung S8, where you can manually edit all the settings. You should consider the Samsung S8 has a 10 minute time limit when recording 4K video.
