Frequently asked questions

What does the warranty cover?

Our warranty covers all hardware faults, but please note it doesn’t cover accidental damage or software issues. However, we’re here to help with technical support for those matters!

What is a refurbished device?

A refurbished device is a pre-owned item that has been restored to meet high-quality standards. At Reboot IT, we adhere to strict quality guidelines, ensuring that our refurbished products are not the same as used or secondhand items. We meticulously clean, test, and assess each device, replacing worn parts with high-quality components.

Unlike used items, which lack guarantees and rely solely on the seller's word regarding condition, refurbished devices come with assurance of quality and reliability.

What payment options are available?

We offer a variety of payment options to make your shopping experience as convenient as possible! You can pay using all major credit cards, Apple Pay, Google Pay, Shop Pay, Afterpay, Zip Pay, and PayPal. If you prefer, we also accept bank deposits and even cash for in-store purchases!

Samsung Galaxy S8 64GB Black – 5.8" Quad HD+ Super AMOLED Smartphone

The Samsung Galaxy S8 puts a 5.8" dual-edge Super AMOLED Infinity Display (2960 x 1440 Quad HD+) into a compact body, backed by 64GB of storage, 4GB RAM, an octa-core processor and a 12MP Dual Pixel rear camera. It's unlocked for Australian carriers, professionally tested in Melbourne and comes with a 12-month warranty from Reboot IT.

  • 5.8" Infinity Display: a dual-edge Super AMOLED panel that curves into the frame, so you get a generous screen without a bulky phone.
  • Quad HD+ resolution: 2960 x 1440 pixels keep text, photos, maps and video crisp and detailed.
  • 64GB storage: plenty of room for apps, photos, music, podcasts and offline maps.
  • 12MP Dual Pixel camera: Samsung's Dual Pixel rear camera for everyday snaps, family moments and short video clips.
  • Octa-core with 4GB RAM: a 2.3GHz + 1.7GHz octa-core processor paired with 4GB RAM keeps everyday apps moving.
  • Unlocked 4G LTE: pop in a SIM from your preferred Australian carrier for calls, texts and 4G LTE mobile data.

Performance in use

Commuting and streaming. On the train, tram or bus, the 5.8" Quad HD+ display makes video, news sites and social feeds easy to read and enjoyable to watch. The dual-edge Infinity Display design wraps the screen into the curved sides of the phone, so you get more viewing area while the handset still slips into a jacket or jeans pocket. 4G LTE keeps streams, podcasts and downloads moving when you're away from Wi-Fi.

Photos and memories. The 12MP Dual Pixel rear camera is ready for weekend outings, kids' sport, pets, holidays and quick shots of whiteboards or receipts at work. With 64GB of storage on board you can keep a healthy photo and video library on the phone itself, and the sharp Quad HD+ screen is a great way to show your shots to friends and family before you back them up to the cloud.

Work and everyday multitasking. The octa-core processor (2.3GHz + 1.7GHz) and 4GB RAM handle the everyday mix of email, messaging, calendar, web browsing and navigation without fuss. That makes the Galaxy S8 a practical choice as a dedicated work phone, a dependable second handset for travel, or a capable step up for someone moving on from an older, slower phone.

Frequently Asked Questions

Is the Galaxy S8 unlocked?

Yes. It's unlocked, so you can use a SIM from your preferred Australian carrier with no lock-in. Since the 3G networks closed, each carrier keeps its own list of approved handsets, so we recommend a quick check with your carrier before you switch your number across.

Has the phone been reset?

Yes. Every phone is factory reset before dispatch. When it arrives, power it on and sign in with your own Google and Samsung accounts to restore your contacts, apps and backed-up photos.

What battery health can I expect?

Battery health depends on the grade you choose: 70%+ for Grade A and 50–70% for Grade B. Every battery is checked during testing and covered by a 30-day battery warranty.

How much storage does it have?

This Galaxy S8 has 64GB of internal storage. Some of that space is used by the operating system and pre-installed apps, so the space available for your own files is a little lower.

Does it come with a charger or box?

This listing is for the handset itself. A charger, cable and retail box are not included, so plan to use a compatible charger you already own or pick one up separately.

Is shipping free?

Yes. The Galaxy S8 ships with free standard AU shipping, dispatched from our Melbourne warehouse.

What does the 12-month warranty cover?

The 12-month warranty from Reboot IT covers hardware faults that occur under normal use. If something goes wrong, contact our support team and we'll arrange a repair, replacement or refund in line with our warranty terms and the Australian Consumer Law.

Backed by Reboot IT. Every Samsung Galaxy S8 is professionally tested, factory reset, cleaned and graded at our Melbourne workshop before it leaves us. It comes with a 12-month warranty from Reboot IT covering hardware faults under normal use, a 30-day battery warranty, and free standard AU shipping. Reboot IT has been supplying refurbished technology to Australian homes, schools and businesses since 2001, and our local team is here to help if you ever need it. Your rights under the Australian Consumer Law apply in addition to this warranty.
