Samsung Galaxy S23 Ultra 5G 256GB Green Unlocked Smartphone – Renewed

Product Overview

The Samsung Galaxy S23 Ultra identified by ASIN B0C5443MCX is a renewed U.S.-version smartphone with 256GB of internal storage, 8GB of RAM, an unlocked cellular configuration, and a Green finish. It belongs to Samsung’s 2023 Galaxy S flagship family and combines a large display, integrated S Pen, multi-camera system, 5G connectivity, and high-capacity battery.

The phone uses a 6.8-inch Edge Quad HD+ Dynamic AMOLED 2X display with a 3088 × 1440 resolution and an adaptive refresh rate from 1Hz to 120Hz. Processing is handled by the Snapdragon 8 Gen 2 Mobile Platform for Galaxy. The rear camera system includes a 200MP wide camera, 12MP ultra-wide camera, and separate 10MP telephoto cameras providing 3x and 10x optical zoom.

A 5,000mAh typical battery supports compatible 45W wired charging, Fast Wireless Charging 2.0, and Wireless PowerShare. The device also supports Wi-Fi 6E, Bluetooth 5.3, NFC, 5G, Samsung Knox security, and IP68-rated resistance to water and dust under specified laboratory conditions.

This listing represents a renewed device rather than a factory-new unit. Cosmetic condition, battery wear, refurbishment history, packaging, accessories, and warranty coverage can therefore differ from an originally sold new Galaxy S23 Ultra.

Maintenance and Care

Clean the display, camera lenses, and exterior surfaces with a soft, dry, lint-free cloth. Abrasive materials and strong cleaning chemicals can damage protective coatings or exterior finishes.

Keep the USB Type-C port, S Pen compartment, microphones, speakers, and SIM area clear of dirt and debris. Remove foreign material carefully without inserting sharp objects into ports or openings.

The IP68 rating does not make the device permanently waterproof. Water and dust resistance can decline because of wear, impact damage, repairs, or deterioration of seals.

Use compatible USB-C charging equipment and undamaged cables. Heat can accelerate lithium-ion battery degradation, so prolonged exposure to high-temperature environments should be avoided.

For renewed devices, battery condition should be monitored because prior charge cycles and previous usage can affect remaining capacity. Important photographs, documents, messages, authentication data, and other files should be backed up regularly.

Software and security updates should be installed when available for the exact model and carrier configuration.

Safety Information

• The device contains a rechargeable lithium-ion battery that is not intended for routine user removal.
• Do not puncture, crush, burn, or intentionally disassemble the battery.
• Stop using the phone if the battery becomes swollen, physically damaged, or unusually hot.
• The Galaxy S23 Ultra and its integrated S Pen carry an IP68 rating under specified laboratory conditions.
• The IP68 test conditions include freshwater submersion up to 1.5 meters for up to 30 minutes.
• Water and dust resistance are not permanent and can decrease with normal wear.
• The device is not intended for beach or pool use based solely on its IP68 rating.
• Use compatible chargers, cables, and wireless charging equipment.
• Keep the S Pen and SIM components away from young children when removed from the phone.

Technical Specifications

Product History

Samsung introduced the Galaxy S23 Ultra on February 1, 2023 alongside the Galaxy S23 and Galaxy S23+. General availability began on February 17, 2023 in the United States and other markets.

The S23 Ultra followed the Galaxy S22 Ultra and continued the Ultra model’s integrated S Pen design. A major hardware change was the adoption of the 200MP primary camera and Snapdragon 8 Gen 2 Mobile Platform for Galaxy.

The original storage options included 256GB, 512GB, and 1TB configurations. Standard colors included Phantom Black, Cream, Green, and Lavender, with additional colors offered through selected channels.

The Galaxy S24 Ultra succeeded the S23 Ultra in 2024. Later Galaxy S Ultra generations continued Samsung’s large-screen flagship smartphone line.

Package Contents

• Samsung Galaxy S23 Ultra smartphone.
• Charging or data cable.

The referenced product is renewed, so its package should not automatically be assumed to match Samsung’s original factory-new packaging. Samsung’s original S23 Ultra package included an S Pen stored inside the phone, USB-C data cable, and SIM-ejection tool, while a wall charger was sold separately.

Because renewed listings can have seller-specific accessory policies, only accessories explicitly supplied with the individual renewed unit should be treated as guaranteed package contents.

Compatibility

The referenced configuration is identified as an unlocked U.S.-version Galaxy S23 Ultra. Cellular service depends on supported network bands, carrier certification, account requirements, SIM or eSIM provisioning, and network availability.

The U.S. unlocked Galaxy S23 Ultra belongs to the SM-S918U1 model family. The exact model and IMEI should be used when confirming service with a wireless carrier.

The phone supports 5G and LTE networks. Wi-Fi 6E functionality requires compatible network equipment and availability of the appropriate wireless spectrum.

Galaxy S23 Ultra does not include a microSD card slot. Storage expansion therefore requires cloud storage, compatible USB storage, network storage, or another external method.

The integrated S Pen is designed specifically for supported Galaxy S23 Ultra functions including handwriting, drawing, annotation, navigation, and remote-supported functions.

Bluetooth accessories can include compatible headphones, speakers, keyboards, watches, controllers, and other peripherals. USB Type-C accessories must meet the relevant Android, USB, and Samsung compatibility requirements.

Frequently Asked Questions

What does B0C5443MCX identify?

B0C5443MCX identifies a renewed Samsung Galaxy S23 Ultra 5G U.S. version with 256GB storage, Green finish, and unlocked cellular status.

What UPC is associated with B0C5443MCX?

The referenced renewed listing identifies UPC 733428253184. This listing-specific barcode should not be assumed to identify every factory-new or refurbished Galaxy S23 Ultra Green 256GB configuration.

Is B0C5443MCX factory-new?

No. The referenced configuration is renewed. Its prior usage, cosmetic condition, battery health, packaging, and accessory set may therefore differ from a new retail device.

What model is the U.S. unlocked Galaxy S23 Ultra?

The U.S. factory-unlocked Galaxy S23 Ultra belongs to the SM-S918U1 model family. The precise model identifier can be confirmed through the phone’s software settings.

How much storage does this configuration have?

This configuration has 256GB of internal storage. User-accessible storage is lower because system software and preinstalled data occupy part of the total capacity.

Can a microSD card be installed?

No. The Galaxy S23 series does not support microSD storage expansion.

Does the S23 Ultra include an S Pen?

The Galaxy S23 Ultra has an integrated S Pen compartment, and the original device design includes an S Pen. When evaluating a renewed unit, the pen should be confirmed physically because renewed-device completeness can vary.

Is the Galaxy S23 Ultra waterproof?

The device carries an IP68 water- and dust-resistance rating rather than a guarantee of permanent waterproofing. Resistance can decline because of wear, physical damage, or repairs.

What does IP68 mean for this phone?

Samsung’s documented test conditions include submersion in freshwater up to 1.5 meters for as long as 30 minutes. Beach and pool use are not covered by that laboratory description.

What processor does the Galaxy S23 Ultra use?

The S23 Ultra uses the Snapdragon 8 Gen 2 Mobile Platform for Galaxy, a processor configuration developed for Samsung’s Galaxy S23 generation.

How many rear cameras are included?

The phone has four physical rear cameras: one wide camera, one ultra-wide camera, and two telephoto cameras.

What is the difference between 3x and 10x telephoto cameras?

The two telephoto cameras provide different optical magnification levels. The 3x camera covers moderate telephoto framing, while the 10x camera provides substantially greater optical magnification for distant subjects.

Does the Galaxy S23 Ultra support 100x zoom?

Samsung documents digital-assisted zoom up to 100x. Image quality generally decreases as digital magnification increases beyond the optical ranges of the telephoto cameras.

What operating system originally shipped with Galaxy S23 Ultra?

The Galaxy S23 Ultra launched with Android 13 and Samsung One UI 5.1. A renewed unit may already contain a later supported software version.

Can the Galaxy S23 Ultra use Samsung DeX?

Yes. Samsung DeX supports compatible desktop-style workflows using appropriate displays, computers, connections, and software.

How should a renewed Galaxy S23 Ultra be identified?

Check the model number, IMEI, storage capacity, color, software information, and hardware condition directly on the device. These details are more reliable for service and network verification than the commercial listing identifier alone.

What warranty applies to B0C5443MCX?

The referenced renewed listing documents a limited 90-day warranty. This should not be confused with Samsung’s warranty terms for originally purchased new devices or Samsung Certified Re-Newed products.

Buying Considerations

• Confirm that the device is the 256GB Green U.S. unlocked configuration.
• Verify the model number and IMEI before carrier activation.
• Recognize that the referenced unit is renewed rather than factory-new.
• Inspect the display for scratches, dead pixels, image retention, touch-response issues, or cracks.
• Check the integrated S Pen and confirm that the phone detects it correctly.
• Test the S Pen compartment for proper insertion and removal.
• Battery capacity can decline with age and previous charge cycles.
• Test all rear cameras and the front camera on a renewed unit.
• Check the 3x and 10x telephoto cameras separately.
• Test wired charging, wireless charging, and USB data connectivity.
• Confirm that previous-user account locks have been removed.
• There is no microSD card slot.
• A wall charger should not be assumed to be included.

Customer Feedback Summary

This section is a generalized summary of recurring themes reported in public customer discussions and independent reviews. These observations are not verified product specifications, and experiences with individual renewed units can vary.

The display is frequently identified as a major strength. Users and reviewers commonly note its high resolution, strong outdoor visibility, responsive refresh rate, and large viewing area for video, photography, gaming, reading, and productivity.

The camera system receives substantial positive feedback for its versatility. The combination of a high-resolution main camera, ultra-wide lens, and separate 3x and 10x telephoto cameras gives users several framing options without relying entirely on digital cropping.

Battery endurance is also commonly reported as improved compared with the preceding Galaxy S22 Ultra generation. Actual runtime still varies with screen brightness, 5G use, gaming, navigation, camera activity, wireless connections, and battery condition.

The integrated S Pen is valued by users who regularly take handwritten notes, annotate documents, edit images, or draw. Other users report using the stylus less frequently, making its usefulness dependent on individual workflows.

The physical size and weight are recurring limitations. The large screen and integrated stylus produce a device that can feel bulky during extended one-handed use or when carried in smaller pockets.

Renewed-device feedback is more variable than feedback for factory-new hardware. Cosmetic condition, battery health, replacement components, packaging, and included accessories can differ between individual refurbished units.
