Precautions. 1.Carefully look at the screen for imprints, data cables, headphone jacks, speaker holes, and hanging tape holes for dust.

2.Carefully look at the battery lock of the fuselage to see if there are scratches, and whether there are spin marks on the spindles of the upper and lower covers.

3.Double-check whether there are any records in the WAP and voice functions and the call log information function.

4.Smell the smell, the new machine has sandalwood, which dissipates 10-12 days after purchase, this smell is different from the general detergent and perfume smell. The body must not have sticky wax and oil (if there is, it will be beautified by the merchant).

6.Look at whether the gap between the seams of the shell is uniform and less than 1mm, whether there are pry marks, and whether there are picks at the two sealing points under the screen in the upper cover.

7.Compare the elasticity of the buttons and the brightness of the inner and outer displays with the new machine.

8.Carefully look at whether the fixed gong nails of the fuselage are spindled, painted and inked (you can use a magnifying glass), and whether the trademark has pry marks.
