What consideration is NOT necessary when ensuring field technicians can view troubleshooting clips on smartphones?

When ensuring that field technicians can view troubleshooting clips on smartphones, the screen size is not a critical consideration. This is because modern smartphones typically have adequate screen sizes that can accommodate video playback effectively, regardless of the resolution or format of the video.

In contrast, video resolution is vital since a higher resolution can enhance clarity but may impact loading times if the device or network isn't up to par. Internet connectivity is also an essential consideration; without a reliable connection, technicians would not be able to stream or download the clips needed for troubleshooting. Additionally, file format matters because it must be compatible with the smartphone's media player, ensuring that the video can be opened and played without issues.

Overall, while screen size does play a role in user experience, it does not pose as significant a barrier to accessibility in most scenarios, especially when compared to the other factors involved.
