Introduction
The BLU Quattro 5.7 HD, launched and released in February 2013, was an ambitious entry into the smartphone market by BLU, aiming to offer a large-screen experience with competitive specifications for its time. Although it has since been discontinued, the device serves as an interesting case study of early 2010s Android smartphones, balancing performance, and affordability. Priced at around 220 EUR during its release, it catered to consumers looking for substantial screen real estate without breaking the bank.
