I have been using an iPhone 5S (my old phone) for recording most of my video. I started using the front camera, now moved on to the rear camera... that made a big difference on it's own. I also have an iPhone 7 Plus (which is my current phone), however have not been recording with it due to needing it for other things as I record. My biggest issue with recording is lighting as well, and plan on investing in some lighting in the near future to help with this issue. So far I have just been playing with the angles to get as best of a shot as possible, without blowing out the shot. Coincidentally my main mic right now is the iPhone 7 Plus... it is serving its purpose at the moment, however would like to upgrade to something else for a mic, something i could also connect to a computer.
