Scenario 3: A little bit of everything, on a budget: If you are on a budget, but would still like to have a good experience with your phone, look into the used phone market for older higher-end phones, these are usually far better choices than the A02, even though they are old.
My Choice
If I had to choose between these two phones, I would choose the Samsung Galaxy Z Flip4.
The reason for this choice is simple. While the A02 serves a specific purpose for those on a very tight budget, the Z Flip4 offers an entirely different experience, a far superior device in almost every aspect, with a unique foldable design, a display that is more than 5 times brighter, much better resolution, vastly superior performance, more storage, more RAM, amazing cameras and cutting-edge features. The only thing it might lack is battery capacity on paper, but in some use cases, it can still offer an equally good battery life or even better. While it comes at a high price point, the experience it offers is far beyond what the A02 can provide. The Z Flip4 is not just a smartphone; it's an example of technological innovation. It is truly a high-end device, the overall experience is much more fluid and pleasurable and makes the price premium worth it.
