Walls are not being tracked while using Track Camera option

[mkhan.mushahid]

Hey, I have been using After Effects CC 2020 latest version. I used my cellphone to record a video of my room. The same video has been imported to my composition. However, when I am using the camera tracking option to track the camera movement, it doesn't show any tracking point on the walls. I have watched so many tutorials online and in those, the wall has some tracker points as well.

However, I don't get any tracker points on my wall. I want to insert the image of a phone on the wall but I am unable to do so because of this issue. Screenshots and sample video have been attached. Please help me out.

The camera tracker needs a significant amount of detail to find something to track. There is no detail at all on the purple wall. The camera move is also a Tripod Pan that moves about 180º so the solution is even more difficult. Even if you added some detail to the wall you are probably going to have to cut the shot up into two or three sections and try and get a decent camera track on each of the pieces. 

There is not enough detail on your wall to even get corner pin tracking to work. When you want to add something to a scene you need to carefully plan and execute the shot so that the tools that are used to track, place, and create mattes have something to work with. Your shot has nothing on the wall to work with and very little in the foreground. I doubt you can get any kind of successful camera solution from the shot.
