Thanks for your reply.
My target is self-capture during traveling abroad, not for profession.
The setup on my OP can help me but there is a drawback as described. I don't expect the video only focusing my face on the scene as those videos available on YouTube
So fundamentally you want to keep your eyes up and looking either at the camera or around at the scenery, and not down at another screen you're using for control. And your phone camera doesn't have wide enough coverage.
What you're doing is the typical "selfie" mode of shooting that is done so often that it's a little confusing as to why you're having trouble with it. Many, even most smartphone have a "selfie" mode that will allow both the camera and the sceen to face you. If you use that mode your eyes will be up and forward even if you look at the sceen. The camera is mounted on a selfy stick that you hold, but never look down at.
There are many cameras that have screens that will flip around and face forward so you can do the same thing. The general category to look at is "Vlogging" cameras. So many, though, that without knowing a lot more about your needs and abilities, recommendation is impossible. Here's one example to get you started, the
Sony ZV-1.
Then there are action cameras, small cameras meant to go with you and capture the action. Motorcycles, hikers, skiers, anything that involves a person, some movement and can't be covered by a bigger camera. Thes cameras are tiny and light. "GoPro" is a big name, but by no means the best. Within the Action Camera class you'll find two general types, ones that have a single lens and shoot a wide shot, typically 150 degrees, and those with dual lenses that capture a full 360 degrees. I personally have both types.
The
DJI Action 2 has an optional battery/screen module that you can face forward. On the end of a selflie stick you can get a reasonable idea of framing, and the shot is quite wide, so if you want more surroundings and less of you, just use a longer stick. Some sticks can be paired with it for remote start/stop. The stabilization is excellent and the video quality is also excellent.
I also have an
Insta360 camera with dual lenses. That gets you everything from you and your surroundings to what's above, below, ahead, behind and sides. Using their app, after you've shot the footage, you can re-frame the shot to include only what you want. Perhaps a shot of yourself, then cut to a shot of what was in front of you, the cut to a shot to the side. And that all comes from one master shot that includes everything. Frankly, these things are a lot of fun. If you'll take a bit of time to look at the sample videos on the maufacturere's sites, you'll get an idea of what's possible.
I would suggest you not worry too much about remote control though. Plan to just start the camera, take your shot, then stop it. Then edit off the and messy start and end to the shot. There are free or low-cost editing apps for every platform.
Drone follow-me is a good solution if there is no regulation/restriction on its use.
I've alreay given you extensive information about this. The above sentence implies you haven't bothered to do any research yet, and still don't know the regulations in the countries you're going to. You're not even listing the countries for us to help.
Drone photography requires you to learn two very different skills that you don't have now. You can't just pick up a drone, toss it into the air, and expect to get anything useful, even if regulations permit free flight. In fact, that's a recipe for a crash. Most novice drone pilots crash and break some part of their drone in the first few flights. Some loose their drones completely. I've been flying drones for a year, and have yet to crash at all, but then I followed a controlled program of developing skills slowly and carefully. Drone piloting is not to be taken lightly, and it will take a surprsing amout of time, patience, and concentration if you want to get good at it. Then there's the legal stuff. Based your very limited description of your usage, I would suggest you do not get involved in drones yet.
Look over the examples I've linked to, see if anything there is at all similar to what you're planning to do, and perhaps make a short list. Then by all means go to YouTube and search for videos shot with the cameras you're considering. Look at what other people are doing with those cameras, see if you can visualize yourself in those shots. Then you'll be able to make a more informed decision.
