A used Galaxy S23 can appeal for its compact screen, separate telephoto camera and capable hardware. A spec sheet describes the model, however, not the exact device you will receive. Give the handover a sensible order: confirm ownership and access before judging the screen and photographs.
1. Confirm the phone can genuinely change hands
Ask the seller to remove their Samsung and Google accounts using the proper process, then confirm that setup can be completed with your own account. Do not rely on a promise that a code or account removal will arrive later. For an online purchase, understand the remedy if activation fails.
Match the model, capacity, colour and identifiers of the actual handset with the order. A used unit may look different from a generic hero image; the delivered device is what needs to match the agreement.
2. Try the 120Hz display and touch surface
Samsung specifies a 6.1-inch Dynamic AMOLED 2X display with adaptive 48–120Hz refresh for Galaxy S23. Check the motion setting and scroll a long page to judge the experience. The 120Hz specification does not tell you whether a particular used panel is in good condition.
Show white, grey and dark backgrounds to look for tint, image retention or irregular patches. Move an icon toward the edges to test touch input. Inspect the glass under angled light and, if there is a screen protector, consider the condition beneath it.
3. Photograph with all three cameras
Samsung lists Main, Ultra Wide and a separate 3x telephoto camera. Shoot the same subject at wide, standard and 3x in good light, watching focus and any unusual spots. Record a short video, switch cameras and play back the sound.
If one view looks soft, clean the lens and retry at a suitable distance before deciding something is broken. Extreme digital zoom is a poor primary test because light, distance and image processing all change the result.
4. Diagnostics are a step, not a warranty
Samsung Members offers diagnostic checks for supported functions such as camera, display and battery. Run those available on the device, but do not treat one pass as a complete inspection. Make a call, test Wi-Fi and Bluetooth, connect a suitable charger and observe the phone in ordinary use.
A used battery reflects charging history, temperature and past use. Design capacity alone cannot promise a particular runtime. If the seller cannot allow a longer trial, understand the post-delivery inspection and return window.
5. Record the exact unit and purchase terms
TECHBUY’s used Galaxy S23 page shows listed storage options and current prices. Before paying, confirm body, display and camera condition, included accessories and warranty for the actual unit. Keep a record of those details for a remote order.

Conclusion
Use this order: activation rights, display and touch, three cameras, connections, then battery and return terms. Sources: Samsung Members diagnostics and Galaxy S23 specifications.
