About Samsung Galaxy S21 FE
The Samsung Galaxy S21 FE presents a compact yet vibrant front with a 6.41‑inch AM‑OLED panel that delivers crisp visuals at a 1080 by 2340 resolution. Its slim chassis measures 74.5 mm wide, 155.7 mm tall and just 7.9 mm thick, tipping the scales at a lightweight 177 grams, making it comfortable to hold and slip into a pocket. The single‑SIM layout keeps the design clean while the color‑rich screen promises vivid colors and deep contrast for everyday media consumption.
Under the surface, the device runs Google Android 12, paired with 8 gigabytes of RAM to handle multitasking and apps with ease. Power comes from a 4 500 mAh battery that supports 15‑watt wired charging, offering a decent balance between endurance and recharge speed. Together, these specifications position the Galaxy S21 FE as a sensible mid‑range option that blends a quality display with solid performance and a manageable form factor.
The US‑specific SM‑G990U model adds 5G Ultra Wideband (UW) support alongside TD‑LTE, unlike the Canadian SM‑G990W variant which offers only TD‑LTE. It also ships with 256 GB of internal storage, a detail not covered in the base model’s description, while the Canadian counterpart shares the same storage capacity. Apart from these regional and network differences, the device matches the base model’s core hardware and software.
