Dear mobile phone users, have you ever encountered the trap of refurbishing a new machine when buying it? These mobile phones look brand-new, but they are actually made of two mobile phones, which are low in price but worrying in quality. Let's teach you how to distinguish refurbished machines and avoid falling into such a trap.

observe carefully

Carefully observe whether there are traces on the screen, data cable, earphone hole, speaker hole, etc. And whether there is dust.

Check the fuselage

Check the battery lock of the fuselage, the rotating shafts of the upper and lower covers, and the two protrusions of the upper cover for poke marks or indentations.

Check function

Check whether there are records in WAP, voice function and call record information function (except for making phone calls during debugging).

Check the shell

Check the shell quality by comparing brightness, uniformity, hue and granularity.

smell

Smell it. The new machine should smell of sandalwood, not detergent or perfume.

Check the contact point

Check the contact point between SIM card and fuselage battery for wear marks or prying marks.

Look at the seams

Check whether the gap at the joint of the shell is even, whether it is below 1MM, and whether there are pry marks at the two sealing points under the screen in the upper cover.

Compared with the new machine

Compare the elasticity of keys and the brightness of internal and external display screens with the new machine.

Check the fixed gong nail

Check whether there is rotary printing, painting and inking on the fixed gong nail of the fuselage (a magnifying glass can be used), and whether there are prying marks on the trademark.

Check the socket

Check whether the phone tail plug, earplug or charging plug is black. If so, it may be refurbished or used.
