My Choice
I would choose the vivo V40. Although its price is likely to be higher, the sheer difference in performance, display quality, and camera capabilities makes it a significantly better investment for long-term use. I value a smooth, responsive experience and often engage in activities like media consumption, light gaming and photography, for which the V40 is much better suited. The faster charging and more modern features also contribute to a much better overall user experience compared to the A02s. The higher price tag is justified by the advanced features and technology it brings to the table. I do acknowledge that a user who is mainly concerned with cost, and only needs a phone for basic functions would likely find the A02s sufficient.
