Verify Tightness of Screws
When purchasing used machines, buyers should first consider whether the device is still in good condition. This determination plays a crucial role in the decision-making process.
When considering a purchase, sellers may claim that their item has never been disassembled. However, it is essential to conduct a thorough examination of all components to validate this assertion. One reliable method is to meticulously assess the sharpness of the screws.

When inspecting phones that feature a removable back case, it is important to examine the screws on this side for sharpness and scratches. In case the device has been disassembled, it is highly likely that the screws will exhibit signs of wear, fraying, or possibly even obscured edges.
Additionally, it is important to check if there is any overlapping of stickers on the device’s body. Genuine distributors typically apply a small stamp on the screw or body, so be cautious of machines that have stamps on all the screws as this may be an attempt to deceive.
