Here are three practical questions to help users decide:

Personal Choice

If I were to choose between these two, I'd pick the Samsung Galaxy Z Flip3 5G. Here's why:

As a tech journalist and analyst, I'm fascinated by innovation, and the Z Flip3 is packed with it. While the battery isn't the largest, I'm comfortable with managing my charging needs given the performance and features that the phone offers. The foldable design is a major appeal for its compact size and the novelty of its form, and as an avid photographer, its camera and video quality is also more than appealing. The performance boost from the Snapdragon 888 chip makes a massive difference in overall experience. The novelty of the form factor is also an important factor. The Nokia G21 is a solid phone, but it caters to a different need, and for my priorities, the Z Flip3 offers far better experience.

Ultimately, both phones serve different niches of the market, and the best choice depends entirely on your personal needs and priorities. I hope this breakdown provides a good starting point for anyone on the fence.
