Not really. Some cellphone cameras can do HDR based on the same basic concept we use. However, the HDR software in a cellphone is very limited compared to the much more sophisticated dedicated programs we use. A professional-quality HDR image starts with higher quality images than your cellphone is capable of, and then goes through several steps: pre-processing the source images, blending those images with different settings to find the best combination, and then tweaking the final result. In many cases, additional Photoshop retouching is needed to achieve the desired result.
