My Choice
I would choose the Samsung Galaxy M55. The A02s is simply outclassed in nearly every single specification, with the exception of the single depth sensor. The M55 offers a drastically better user experience thanks to its superior display, far more powerful processor, enhanced cameras, faster charging, more modern software, additional features, superior build quality and significantly more storage.
The A02s is only suitable for the most budget conscious buyer who has minimal smartphone needs, whereas the M55 is a good all round smartphone that would provide a significantly superior experience for the vast majority of users.
While the A02s is certainly the more budget friendly option, the gap in experience is simply too great, and the M55 provides much better long-term value. The additional cost is justifiable for the enhanced performance, superior display, better camera and more modern features that it offers.
