A:AnswerI've flown more than one Mavic Pros without having phone service on the phones that I used, I've even used a tablet that wasn't service capable. This would tell me the phone isn't your problem.
A:AnswerYes and No!
If you want your TV, iPhone, iPad widescreen to be filled then YES, the mini does film in widescreen.
This are the some specs on the Mini
The Mavic Mini has a 12 MP, 1/2.3-inch CMOS sensor with a field-of-view of 78°.
The camera can shoot JPEG images in 4:3 or 16:9 aspect ratio.
Video resolution maxes out at 2.7 K at either 25 or 30 fps. FHD 1080p video is also available in 25, 30, 50 or 60 fps. The Mavic stores videos in MP4 format.
So it will look great on any widescreen TV or monitor filling up the screen.
Now I’m assuming that you are referring to Widescreen TV:
The adopted industry standard of 1:78 to 1. This is comprable to most of the so called Widescreen TVs
Now Letterboxed (widescreen) refers to the original format the Movies are filmed in. This can range from 1:66, to 2:75.
If you are referring to Letterbox widescreen format the answer is NO
A:AnswerDon’t know exactly, but I’ve been able to fly over 25mins with each battery fully charged, The 3 bank charger is very nice, and can be used to charge the controller and / or cell phone if needed.
A:AnswerNot when I bought at the beginning of Jan 2020. Buy direct from DJI it is reasonable. Buy immediately because there is a time limit to initiate subscription: it’s ok if you bought from BestBuy: I did
A:Answeryou can but limited you can only go 395 ft up (because of the laws in place) but it has about a 2.5 mile range and it films awesomely if you get one get the fly more pack definitely worth the extra money and you can get filters for the camera on amazon all in all you won't go wrong it isn't required to get a license to fly because of the weight even with the filter it still remains under the weight.

A:AnswerNo, it only concentrates on a static subject. If you start a quickshot and move, you will walk out of the frame. Some hope this will be changed in a firmware update, but since the a/c has no obstacle avoidance to the front, back or sides, it could be dangerous to the drone to try to follow you.
A:AnswerI had mine set at unlimited distance but it would not go but 165 feet and would say reached limit. It said something about payload mode which I can not find any info on.
