Some people worry that buy refurbished mobile phone, then how to test whether it is purchased refurbished mobile phone in mobile phones? Here some tips on cell phones.
Refurbished mobile phone generally use the fake original shell, slit at uneven, there are glitches, cell phones vulnerable to the two parts of the upper and lower case is not closed tight, leaving a great gap phenomenon. Identification with a small finger nail can be inserted into the phone try to cover the upper and lower joints. If we can insert in the first is the refurbishment of aircraft. The new aircraft, like the surface of the shell, like frosted, and there are small particles of mobile phones, but also must not buy. This machine is a JS spray paint the shell up, and over time, paint will come off (small particles of dust on the chassis is the paint job did not vacuum created);
New opportunities opened lid has a hint of sandalwood smell, if refurbished mobile phone, JS generally carried out some of the fuselage beauty, despite the smooth appearance, but not dry, turn over or remove the battery cover after the rubber smell plastic taste, odor or chemical agents;
Keyboard, and data line interface. As the charger plug, data cable plug a long-term reasons, the renovation of mobile phone charging interface will appear difficult to eliminate the black scratches. The refurbished mobile phone over the keyboard on the old machine was modeled on the keyboard or the keyboard. This keyboard in common is relatively soft feel and no new aircraft keyboard toughness;
Charging test. Charge, preferably longer, usually 10 minutes or more. Because there are a number of refurbished mobile phone charging time will be longer power outages. This is also the refurbishment of aircraft to determine a very effective way;
SIM card chip contacts and battery contacts. The two contacts are generally unable to replace JS. If it is refurbished machine, then the contacts on the SIM card chips will leave clear traces of friction, it appears bright, which is caused by excessive friction. If it is new aircraft unused chips, then the contact surface should be flat;
Fixed screws. Mainly depends on knife-edge interface, part of the screws and there is no obvious scratches, internal display whether or pick the bottom two pad marks.
Call quality. Bring their own SIM card test machine, call your friends, preferably fixed-line telephone, ask how the quality of the other party call, call the sound is clear, with or without noise, the current sound, whether the sharp decline in the volume size of the phenomenon;
The price. As the refurbishment of aircraft spare parts, mostly the early product, quality is also poor, the price is also low. If I run across low price to be outrageous and merchants known as parallel imports of mobile phones, it can be concluded for the renovation of the basic mobile phone.
