Editorial note

The eSTAR A28 stands out for its lightweight and compact design, weighing only 100 g, making it easy to carry on a daily basis. Its modern appearance in gold color is also an aesthetic asset. The 800 mAh battery, using nickel-metal hybrid (NiMH) technology, offers good autonomy, allowing for prolonged use without the need for frequent recharging. Additionally, the ability to use a MicroSD memory card up to 8 GB allows for increased storage capacity, which is particularly advantageous for users needing more space. However, the eSTAR A28 has several notable drawbacks. The screen resolution of 240 x 320 pixels is limited, which can affect the display quality of multimedia content. With only 32 MB of internal memory, the device cannot support many modern applications, thus restricting its use. The lack of Wi-Fi connectivity and built-in GPS also hinders effective daily use, as does the poor quality of the rear camera at 0.08 MP. Overall, despite limited performance and some missing features, the eSTAR A28 remains a reasonable choice for those looking for a basic and affordable smartphone, particularly due to its good battery life and attractive design. However, users seeking a more powerful and connected device may be disappointed by its limitations.
