Modern smartphones have photo editing apps for basic product enhancements. You can follow the following steps for product photo retouching on a smartphone: Open your photo editing app (For example, Lightroom or Snapseed). Adjust the brightness, contrast, sharpness, highlights/shadows, and white balance using sliders. Save the changes you made in a preset so you can easily apply them to other products later! Change the background to a plain white backdrop.  Save and export! You have an edited product image!
