You may be worried that your phone is outdated and does not have a built-in wide angle lens, or does the built-in wide angle lens does not meet you quality standards?
Now that is lossless image quality on a wider field of view.
It is always better to use the main camera and use Kase wide angle lens. Main camera has the largest sensor and highest resolution available in your dual or triple camera phones.
It produces 16mm (ff equivalent) focal lenght with the same image quality as your front cam.
