This article belongs to the Product section and not the Article section. If it was a comparison between the two smartphones or between its earlier version and this version, then you can publish it in Article section.
Since you are back after a long time, I suggest you to avoid writing articles which just mention specifications of a product and don't give any more depth. These type of articles don't fetch any traffic neither add any quality. "Top 10/5 of something", "How to troubleshoot/install" or a detailed review of a product/software that you actually use and can give authentic observations are what we are looking for. Basically, add your inputs and observations and not create an article with just specifications of a product.
