Samsung Galaxy A57 5G 256GB Navy

The Samsung Galaxy A57 5G 256GB in Navy is a premium Galaxy A-series 5G smartphone created for customers who want a large, smooth display, reliable daily performance, versatile cameras and dependable battery life. It combines Samsung’s familiar One UI experience with 5G connectivity and generous internal storage, making it suitable for communication, work, entertainment, navigation, social media and photography.

Navy provides a deep, sophisticated finish that gives the Galaxy A57 a distinctive but understated appearance. This handset is supplied brand new and includes 12-month warranty support for qualifying manufacturing faults. ExcellTronics offers fast nationwide delivery across South Africa and secure online checkout. Please review the selected colour, storage capacity and delivery details before completing your order.

Bright, smooth AMOLED viewing

The 6.7-inch FHD+ Super AMOLED Plus display with a refresh rate of up to 120Hz gives the phone a strong foundation for everyday use. AMOLED technology produces deep blacks, vivid colour and strong contrast, helping photographs, video, websites and applications look clear and engaging. The high refresh rate makes scrolling, supported games and interface animations feel smoother than on a standard 60Hz screen.

The large panel provides useful space for reading documents, following maps, typing messages and watching online content. It is also practical for split-screen multitasking when supported by the application. Actual brightness, refresh rate and colour behaviour can vary according to display settings, content, power-saving mode and ambient conditions.

Performance for everyday applications

The Exynos 1680 mobile platform works with 8GB RAM to support responsive everyday operation. The device is designed to handle messaging, banking, browsing, video calls, streaming, navigation and social media, while also giving users enough capacity for normal multitasking. Performance can vary according to software version, temperature, available storage and the number of applications running in the background.

Samsung One UI provides a familiar Android interface with customisation options, privacy controls and access to the wider Galaxy ecosystem. Samsung account features, Google services and certain intelligent functions may require an internet connection, supported language or account sign-in. Keeping the operating system and applications updated is recommended for security, compatibility and reliable performance.

Generous 256GB internal storage

The 256GB capacity provides room for applications, photographs, downloaded documents, music and video. Actual usable storage is lower because the operating system and pre-installed software occupy part of the advertised capacity. Customers who record large amounts of video or keep extensive offline media should monitor free space regularly and use cloud or computer backups for important files.

8GB RAM assists with moving between common applications without constant reloading. Storage and memory specifications refer to this listing and may differ from versions sold in other countries. Always check the model, storage and colour displayed in the basket before payment.

Versatile cameras for everyday moments

The rear system uses a 50MP main camera with optical image stabilisation, supported by a 12MP ultra-wide camera and 5MP macro camera. The main camera is intended for daily photographs and video, while optical image stabilisation helps reduce the effect of small hand movements in supported modes. The ultra-wide camera is useful when you need a broader field of view for groups, buildings or landscapes, and the macro camera is designed for close-range subjects in suitable lighting.

The 12MP front camera supports selfies, video calls and social content. Camera results depend on lighting, subject movement, selected mode and software processing. Features such as portrait effects, night processing and automatic scene optimisation can help in appropriate situations, but good lighting and a steady grip remain important for the best result. Digital zoom enlarges the captured image and should not be confused with a dedicated optical telephoto lens.

Battery built for a full routine

A 5,000mAh typical-capacity battery supports a full schedule of calls, messaging, browsing, navigation and entertainment for many users. Actual battery life varies significantly with mobile signal strength, screen brightness, refresh rate, 5G activity, application use and background synchronisation. Gaming, navigation and high-resolution video generally use more power than light messaging or standby time.

The handset supports up to 45W wired charging with compatible equipment. Charging speed depends on the charger, cable, temperature and current battery level. A compatible wall charger may be sold separately depending on the package, so check the supplied contents rather than assuming that every accessory is included. Reputable USB-C charging equipment is recommended for safety and consistent operation.

5G, Dual SIM and useful connectivity

5G connectivity can provide faster mobile data and improved network responsiveness where compatible service is available. Coverage and speed depend on the network operator, location, congestion and selected plan. The listing is configured for Dual SIM use, helping customers separate personal and business numbers or use more than one mobile service. SIM and eSIM availability can vary by regional model and network support.

Wireless connectivity supports everyday accessories and services such as Bluetooth audio, Wi-Fi networking, location services and contactless functions where available. Some network or payment features depend on regional software, a supported service provider and account registration. The phone is supplied network unlocked unless otherwise stated on the product page.

Design and practical durability

The handset combines IP68-rated dust and water resistance under controlled laboratory conditions. Water and dust resistance is tested under laboratory conditions and is not a guarantee against every type of exposure. Resistance can reduce with wear, impact or repairs, and liquid damage may not qualify as a manufacturing fault. The device should not be deliberately submerged, charged while wet or exposed to salt water.

A protective case and suitable screen protection can reduce everyday scratches and minor impact damage, but accessories do not make a phone indestructible. Accidental damage, cracked glass, misuse, unauthorised repairs and normal wear are not normally covered as manufacturing defects.

Who should choose this Galaxy phone?

The Samsung Galaxy A57 5G is well suited to customers who want a modern Samsung interface, a large AMOLED display, 5G connectivity and useful camera flexibility without moving to the cost of the Galaxy S series. The 256GB capacity is especially helpful for buyers who keep applications, photos and downloaded media directly on the device.

It is a practical option for students, professionals, families and everyday users who value a balanced feature set. Customers focused on extreme gaming, specialist optical zoom or flagship video tools should compare higher-tier Galaxy models, while buyers focused mainly on calls and light applications may prefer a more affordable A-series option.

This product is sold brand new. ExcellTronics provides 12-month warranty support for qualifying manufacturing faults unless a different period is clearly stated on the page.

Orders are processed after payment and stock verification. Fast nationwide delivery is available across South Africa, with timing depending on destination, courier operations and payment clearance. Secure checkout is available online. Full terms appear in the Warranty & Delivery tab on this product page.

Warranty Support, Claims and Return Requests

ExcellTronics wants you to know what support to expect after your order. Warranty cover is product-specific. Many eligible devices carry 12 months of manufacturer warranty, while selected products carry 24 months where that period is stated. Check the individual product listing and your order documents for the exact warranty period, warranty provider and service route for the item you purchased.

Where a Samsung or Apple manufacturer warranty is stated for your product, we can help direct your claim through the applicable support channel. The manufacturer's written terms and the product assessment determine whether a reported issue is covered. This tab explains how to contact us and prepare an item for review; it is not a blanket promise of an automatic exchange, replacement or cash refund.

How to open a warranty or return request

  1. Contact ExcellTronics before sending or handing over the product. Use the contact details below and ask for a return or assessment reference.
  2. Include your order number or proof of purchase, the product name and model, the device IMEI or serial number, and a clear description of the issue and when it started.
  3. For visible damage, an incorrect item or missing contents, include clear photographs of the product, parcel and packaging. A short video can help show an intermittent issue.
  4. Wait for written instructions telling you where to send the item, what to include and how it should be packed. Do not send an item to an address or service centre that we have not confirmed for your case.

Opening a request does not itself approve a return or determine its outcome. We may need to verify the order, serial or IMEI, item supplied, packaging details and reported fault before confirming the next step. Please keep messages, photographs, courier receipts and any assessment reference until the case is closed.

Condition and completeness for approved returns

For a return approved for a reason other than a reported product fault, keep the item unused, unopened and unactivated, with its original seals and packaging intact. This includes not inserting a SIM card or connecting the device to Wi-Fi. If we approve that return in writing, the product must be returned in saleable condition: complete, clean, unmarked, undamaged, and with the original box, manuals, inserts, supplied accessories, bundled items and promotional gifts that came with the order.

Separately supplied accessories included in an approved non-fault return must also be unused, uninstalled, unpaired or unactivated where applicable, and returned complete in their original saleable packaging. Missing parts, broken seals, signs of use, scratches, account locks, removed labels or packaging damage may affect whether that non-fault return can be accepted. The saleable-condition requirement in this paragraph applies to a non-fault return approved in writing; it is not a condition for reporting a product fault.

If the item delivered does not match your order, leave it unopened and unused, keep the parcel and all packaging, and contact us promptly with photographs and your order number. We will verify the order and provide case-specific instructions.

Assessment, coverage and next steps

A warranty assessment may be carried out by the relevant manufacturer, service provider or other appropriate assessor. A claim may require inspection or troubleshooting before a decision can be made. Manufacturing faults may be covered where they meet the written terms for the specific product. Accidental or impact damage, liquid exposure, misuse, unauthorised repair or modification, altered serial or IMEI details, and normal wear may fall outside a manufacturer's warranty where its terms exclude them.

If the assessment identifies damage or a condition outside the written warranty coverage, we will explain the assessment result and available next steps. Paid work will not proceed without your approval. Any remedy for a confirmed issue is determined by the applicable product terms and circumstances. Nothing in this information removes responsibilities or rights that cannot lawfully be excluded.

Protect your data before service

Back up important information before handing over a phone, tablet or other device. Assessment or repair may require a reset, software reinstallation or replacement of a component, and stored data may be lost. Remove your SIM card and memory card before dispatch. Never send us your Apple, Samsung, banking or email password. If a manufacturer requires a security setting to be changed for service, follow the instructions we confirm for your case after backing up your data.

Contact ExcellTronics

Email admin@excelltronics.co.za or call/WhatsApp 071 770 4010. For order queries, you can also call 076 732 2518. Include your order number in every message so we can locate your purchase and assist efficiently.

Shipping and Delivery Across South Africa

ExcellTronics arranges courier delivery to customers throughout South Africa. We prepare an order after payment has cleared and the order and stock details have been checked. For major centres, delivery is typically 24–48 working hours after dispatch. This is an estimate, not a guaranteed delivery appointment; outlying areas, courier routes, peak periods, weather and other operational delays can extend the timeframe.

Before your order is dispatched

Check your delivery address, suburb, postal code, contact number and email before completing checkout. Include unit, gate, building or business details that help the courier locate you. Please make sure someone authorised is available to receive the parcel and can provide the order or delivery details requested by the courier.

Orders are sent to the delivery address confirmed at checkout. Contact us as soon as possible if you spot an address error. Once a parcel has been collected by the courier, an address change may not be possible or may cause delay and additional courier charges. If a delivery attempt fails because the address or contact details are incomplete or no recipient is available, we will confirm the next step and any applicable re-delivery charge before it is incurred.

Dispatch updates and tracking

We provide dispatch or tracking details when they are available from the courier. Tracking may take time to show its first scan after collection. Please use the courier tracking link for route updates and keep your order number available when contacting us. A delivery estimate can change while a parcel is in transit; we will help you follow up when tracking shows a delay or an exception.

For your security, accept a parcel only at the delivery address confirmed for the order and check that the outer parcel is intact. Do not share one-time banking codes or account passwords with a courier or anyone claiming to represent ExcellTronics.

If the parcel looks damaged

If the outer parcel is visibly crushed, torn, opened or wet, photograph it before opening where possible. Ask the courier to record visible damage on the delivery record. If the parcel appears seriously compromised, you may refuse delivery and contact us so we can advise the next step. If you have already accepted it, stop unpacking if the product or inner packaging appears damaged, keep all packaging and take clear photographs of the parcel, shipping label, seals and affected items.

Send the photographs, order number and a brief description to admin@excelltronics.co.za or WhatsApp 071 770 4010 promptly. Please do not discard the box, labels, protective materials or courier documents while we review the delivery issue.

If an item is missing or does not match your order

Keep the product and parcel contents as received. Do not open or use an item that is different from the one on your order confirmation. Photograph the shipping label, parcel, seals and contents, then contact us with your order number. We will check the order and dispatch information and give you instructions for collection, replacement or another appropriate next step.

Returning an item for assessment

Contact ExcellTronics before sending any device or accessory back. We will confirm the correct return address, packing instructions, items needed for the assessment and the courier arrangement for your case. Sending an item without these instructions can delay identification and processing. Pack the product securely, include only the accessories or documents requested, and keep your courier receipt and tracking number.

Return transport arrangements and any applicable charges are confirmed after we review the reason for the request and the applicable product process. We will not ask you to pay an unconfirmed charge. These steps describe our delivery and support process and do not remove responsibilities or rights that cannot lawfully be excluded.
