Manual of product Star Duos B7722
Editorial note
The Samsung Star Duos B7722 presents itself as a compact and lightweight smartphone, weighing only 105 g. This model is easy to carry and handle, making it practical for everyday use. Its built-in Wi-Fi connectivity and 5 MP rear camera with LED flash are assets that enhance the user experience, just like the instant messaging features and MMS sending. However, the product has notable limitations. The 3.2-inch screen with a resolution of 240 x 400 pixels may seem outdated, which could affect the visual experience, especially when consuming multimedia content. Additionally, the internal memory of only 270 MB may quickly prove insufficient for users wanting to install multiple applications or store large files. The lack of built-in GPS and support for the WAP protocol also limits navigation features and access to certain Internet services. In terms of performance, the Samsung Star Duos B7722 offers satisfactory battery life thanks to its 1200 mAh battery, allowing for up to 12.5 hours of talk time and 461 hours on standby. However, the limitations in memory and display could disappoint some users, thus affecting the perception of value for money. In summary, the Samsung Star Duos B7722 is a smartphone that will suit those looking for a lightweight and practical device, but users demanding in terms of performance and display quality may find better options elsewhere.Score details
