Samsung Galaxy S21+ 5G 128GB Phantom Black Unlocked Smartphone (Renewed)

Product Overview

The Samsung Galaxy S21+ 5G is a large-screen Android smartphone from Samsung’s Galaxy S21 family. The product identified by ASIN B08WHKF6RJ is a renewed, unlocked United States version with 128GB of internal storage and a Phantom Black exterior. Public product records consistently identify this configuration as part of the Galaxy S21+ 5G line.

The Galaxy S21+ uses a 6.7-inch Dynamic AMOLED 2X display with a 2400 × 1080 resolution. The United States hardware uses an octa-core processor with a maximum documented CPU frequency of 2.84GHz, paired with 8GB of RAM. Samsung specifies 128GB and 256GB storage configurations for the model family.

Its rear camera system combines 12MP, 64MP, and 12MP sensors, while a 10MP camera is positioned on the front. The phone supports 8K video recording, 5G cellular connectivity, wireless charging, NFC, Bluetooth, and USB-C connectivity. A 4,800mAh typical battery is integrated into the handset.

Because this specific product record describes a renewed device, cosmetic condition, battery wear, included accessories, and prior service history can vary between individual units. Those variables should not be treated as original factory specifications.

Technical Specifications

The table reflects Samsung’s published Galaxy S21+ specifications. Regional network bands and software behavior may vary by hardware version, carrier, and firmware.

Package Contents

This product is identified as renewed rather than as an original sealed retail unit. Public records do not provide sufficiently consistent documentation of the accessories supplied with every renewed B08WHKF6RJ unit.

Package contents can therefore vary by refurbisher or seller. The included cable, power adapter, SIM tool, documentation, and other accessories should be verified from the individual unit’s accompanying information rather than assumed from the original factory package.

Compatibility

The referenced configuration is described as an unlocked United States Galaxy S21+ 5G. An unlocked device can generally be activated outside its original carrier relationship, but compatibility still depends on the destination network’s supported bands, activation rules, IMEI eligibility, and account requirements.

The SM-G996U hardware family supports multiple generations of cellular networking, including 5G and LTE. Actual access to technologies such as 5G, Wi-Fi calling, visual voicemail, and carrier aggregation depends on the service provider and firmware configuration.

USB-C accessories can be used for compatible charging, data transfer, and wired audio functions. Bluetooth accessories such as headphones, speakers, watches, keyboards, and vehicle systems require compatible Bluetooth profiles.

Common Uses

• Voice calling and text messaging.
• 5G and LTE mobile internet access.
• Web browsing and email.
• Photography using wide, ultra-wide, and zoom camera modes.
• Video recording up to supported 8K resolution.
• Video conferencing and front-camera communication.
• Streaming movies, television, music, and other media.
• Mobile gaming.
• Navigation and location-based applications.
• Social networking and messaging applications.
• Document viewing and mobile productivity.
• Contactless functions using compatible NFC services.
• Connecting to compatible Bluetooth accessories.
• Transferring files between supported computers and mobile devices.

Maintenance and Care

Clean the display and exterior with a soft, lint-free cloth. If additional cleaning is necessary, use minimal moisture and avoid allowing liquid to collect around the USB-C connector, speaker openings, microphone ports, buttons, or SIM area.

Avoid abrasive cleaners, compressed particles, sharp objects, and harsh solvents that can damage surface coatings or seals. Allow the USB-C connector to dry fully before attaching a charging cable if the device has been exposed to moisture.

Battery condition is especially relevant to a renewed smartphone. Rechargeable batteries lose capacity through age, heat exposure, storage conditions, and charge cycles, so an individual renewed unit may not provide the runtime of a new factory battery.

Back up important files before factory resets, repair work, trade-in, or ownership transfer. System and application updates should be installed when supported for the specific device and network configuration.

Safety Information

• Do not use the phone if the battery is swollen or the enclosure begins separating unexpectedly.
• Stop charging if the device, cable, or adapter produces smoke, unusual odors, or abnormal heat.
• Do not puncture, crush, burn, or intentionally open the built-in rechargeable battery.
• Do not connect a charging cable while liquid remains inside the USB-C port.
• Use charging equipment that meets the electrical requirements of the device.
• Avoid prolonged exposure to excessive heat or direct sunlight.
• Follow applicable laws governing mobile-device use while operating a vehicle.
• Use appropriate audio levels when listening through headphones or earbuds.
• Have damaged batteries or internal components serviced using appropriate electronic-device repair procedures.

Product History

The Galaxy S21+ was introduced in 2021 as the middle-sized model in Samsung’s initial Galaxy S21 flagship family. It was positioned between the smaller Galaxy S21 and the more extensively equipped Galaxy S21 Ultra.

The S21+ retained many of the standard S21’s core specifications while using a larger 6.7-inch display and a higher-capacity 4,800mAh battery. The original family included 128GB and 256GB storage options and 8GB of RAM for the S21+.

Later Galaxy S generations succeeded the S21 family. Because software-support schedules change over time and can vary by region or carrier, current security-update eligibility should be checked against Samsung’s active device-support listings rather than assumed from the phone’s original launch policy. Samsung maintains a current security-update scope for supported Galaxy products.

Not necessarily. The original specification describes a 4,800mAh typical battery, but rechargeable batteries lose usable capacity with age and cycling. Battery condition in an individual renewed unit can therefore differ from original factory performance.

Buying Considerations

• This product is renewed, so cosmetic condition and previous use can vary between individual units.
• Battery health should be considered separately from the original 4,800mAh factory specification.
• The 128GB internal storage cannot be expanded with a microSD card.
• Carrier compatibility should be checked using the device IMEI and intended service provider.
• Included accessories can vary because the listing represents a renewed product.
• The phone does not have a dedicated 3.5 mm headphone jack.
• The 6.7-inch enclosure is larger than compact smartphone designs.
• The screen resolution is FHD+ rather than the higher QHD+ resolution found on some Ultra-series models.
• Software and security-support status should be checked because the Galaxy S21+ originated in 2021.
• A renewed unit should be checked for screen burn-in, camera defects, charging-port wear, speaker issues, frame damage, and battery degradation.
• Storage, color, condition, and model information should be compared with the device’s own Settings screen after receipt.

Customer Feedback Summary

This section is a generalized summary of recurring public feedback about the Galaxy S21+ and renewed examples of the model. These observations describe reported user experiences and should not be treated as verified product specifications.

The display is a commonly praised aspect. Public reviews frequently describe the 6.7-inch AMOLED screen as bright, smooth, and suitable for media consumption, while the high refresh rate is often noted for making scrolling and interface movement appear fluid. Contemporary reviews also highlighted the display and overall responsiveness as major strengths.

Camera feedback is generally positive for everyday photography and versatility. Users often value having multiple rear focal ranges and high-resolution video recording, although image-processing preferences vary and the S21 Ultra’s more advanced camera system generally received stronger evaluations.

Battery reports vary substantially. The S21+’s larger battery can provide useful endurance under moderate workloads, but gaming, navigation, high display brightness, heavy camera use, and cellular conditions can shorten runtime. Battery condition is particularly variable for renewed units because rechargeable cells naturally age.

Performance is commonly reported as responsive for ordinary applications, multitasking, streaming, and gaming. Long-term usefulness can increasingly depend on application requirements and software support because the model belongs to an earlier Galaxy generation.

Recurring limitations include the absence of expandable microSD storage and the lack of a traditional headphone jack. Public discussions of older or renewed units also place significant importance on battery health and physical condition rather than relying only on the original factory specifications.
