Recent analysis of Samsung’s flagship Galaxy smartphone series reveals a number of once-popular features that have been removed from modern devices. This shift reflects changing consumer preferences and the company’s strategic decisions in technology development.
One significant change has been the elimination of microSD card slots, a feature that many users found essential for expanding storage. Samsung first attempted to remove this slot with the Galaxy S6 in 2015, but after facing backlash, it reinstated the feature in the subsequent model. However, starting with the Galaxy S21, the company definitively discontinued support for microSD cards, compelling users to rely on cloud services or opt for more expensive models with greater built-in storage.
Another notable alteration involves the health monitoring capabilities previously integrated into the devices. Earlier models, such as the Galaxy S5 and Note 4, included built-in heart rate monitors and blood oxygen sensors, allowing users to check their health metrics directly from their phones. Following the launch of the Galaxy S10, Samsung removed these sensors, likely to promote sales of its Galaxy Watch smartwatches.
The infrared (IR) blaster, which allowed smartphones to function as universal remote controls, also disappeared after the Galaxy S6. This feature, introduced with the Galaxy S4, was popular among users who appreciated the convenience of controlling various devices from their phones. Despite requests from fans, Samsung opted to eliminate this component to reduce manufacturing costs.
The trend towards a bezel-less design has led to the removal of LED indicators, which previously notified users of missed calls and messages. This feature was discontinued in 2019 to make room for larger displays, with Edge lighting introduced as a partial replacement. However, many users found this new feature less effective.
Additionally, the Edge Display technology, first showcased in the Galaxy Note Edge, has undergone significant changes. Initially designed to provide quick access to apps and notifications, the curved screen has become less pronounced over the years. The latest model, the Galaxy S25 Edge, features a completely flat display, prioritizing a slimmer profile over the distinctive design.
In the realm of biometric security, Samsung had previously experimented with iris scanning technology in the Galaxy Note 7, which allowed users to secure their devices and applications. However, this feature was removed with the Galaxy S10, as ultrasonic fingerprint scanners proved to be faster and more reliable. Concerns over the security of the iris scanner, particularly after reports of it being fooled by high-quality photographs, also contributed to its discontinuation.
Samsung's Galaxy smartphone series has seen the removal of several features over the years, including microSD support and built-in health sensors. These changes reflect the company's strategic shifts and consumer trends in technology usage.
