Conclusion
The NIU Andy 4E2I is a clear representation of budget smartphones from the mid-2010s, offering all the basics at an affordable price. While its performance and features are certainly modest by today's standards, at the time, it served as an accessible option for users who needed essential communication and smartphone functionalities. Its small size, array of colors, and dual SIM capability could still attract users looking for a simple backup phone or a minimalist communication device. However, those seeking advanced functionality, modern app support, or high-quality multimedia experience might want to look for updated devices beyond the discontinued NIU Andy 4E2I.
