Mis fotos de mi teléfono

There is no minimal size of an asset in stock. There are, however, quality requirements. Normally, photos (also from “big” cameras) need some editing to meet the required quality standard. Phone images need to be taken in perfect conditions, as the small sensors normally meet physical limits.

A mobile phone camera that captures only 3MB images is very unlikely to create images that will meet Adobe Stock's quality requirements. The sensor is just too small to capture sufficient detail.

The minimum is 4MB. You would need to upscale your 3MB phone images. But be aware that phone sensors do not capture the detail that actual cameras can capture. Even the highest quality images from actual cameras often require some degree of editing, so you can probably expect to have your assets rejected if they are unedited, especially if you are using flash, which can introduce a number of issues.
