Carefully look at the battery lock of the fuselage to see if there are dial marks, whether there are spin marks at the rotating shaft of the upper and lower covers, and whether there are indentations at the two bumps on the upper cover.
Double-check whether there are any records in the WAP and voice functions and the call log information function.
The shell is based on the contrast (compared to the machine that proves to be good to compare the brightness, uniformity, hue, granularity.
Smell the smell of the new machine with sandalwood, different from the general detergent and perfume smell. The body must not have sticky wax and oil (if there is one, it will be beautified by JS).
Carefully inspect the SIM card contact points for wear marks on the body battery contact points (distinguish the rest of the contact points).
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.
Compare the elasticity of the buttons and the brightness of the inner and outer displays with the new machine.

Anonymous users2024-02-04Mobile phone water ingress emergency treatment method.
1. After the mobile phone gets into the water, the first thing to do is to turn off the power, of course, do not press the power off button, but remove the battery. Because as soon as you press the shutdown button, the mobile phone will be powered on, and it is likely that a short circuit will occur, causing damage to the mobile phone, and then send it for repair as soon as possible. If your phone's warranty has expired and you don't want to send it for repair, you can boldly take it apart!
Wipe the parts of the phone with a tissue, and then blow it with a hair dryer for a few minutes, in order to ensure that all the internal parts are dry, it is advisable to air dry the phone for a few more days before you can turn it on again.
2 Once the mobile phone gets into water, remove the battery immediately, and do not turn it on immediately to understand the condition of the mobile phone. After removing the battery, do not use a hair dryer to deal with it, and immediately send it to the repair professional to disassemble the machine for water treatment, such as falling into sewage or corrosive liquid, and use ultrasonic cleaning and drying before proceeding to the next step of maintenance. If the mobile phone can still be used after water penetration, it should be sent to a professional to deal with it to avoid corrosion of the circuit board and make it impossible to repair.
3 No matter what kind of water the phone falls into, you should remove the phone battery first and no longer power the phone. If it falls into clean water, remove the battery and clean the phone with anhydrous alcohol, because the alcohol volatilizes quickly, and the water on the circuit board can be volatilized together. Then use a heat gun or hair dryer to dry the circuit board, and then power up the test machine, and most mobile phones will work normally.
If it falls into the sewage, it should be cleaned immediately, and the dirt that can be seen should be cleaned first. Use a brush to brush off the impurities attached to the pins of the components. Then, the circuit board is scrubbed with an alcohol cotton ball, and if the pollution is serious, the impurities must be vibrated out with the help of an ultrasonic washing instrument.
Then use an air gun to dry the circuit board, and then repair all the chips.

Anonymous users2024-02-03Battery, SIM card, memory card, etc. Take it out, wipe it well, and dry the phone with a hair dryer... Wipe all the parts that can be wiped and so on are basically drier... Just put the phone in a dry place with the best ventilation.
Let it go for a day and a night... In short, you can't take the battery away and so on, just blow the phone and wait for the battery to be installed and turned on. Because the water inside the phone is not so easy to evaporate.
If you turn it on casually, it is easy to cause a short circuit inside the phone, so it is best to leave it for a while
If conditions permit, take it to the customer service department to do it
This is a little experience of mine
Addendum:It doesn't have to be sent for repair, but it's better to take it to check Nokia's machine is generally more durable, hehe, for your own love machine, if you feel that it is not really used. It's better to take it to check it and ask for peace of mind
If you press * to appear on the mobile phone and the serial number of the cabin after the mobile phone, you will be fine.

Or tariffs, after the product is exported, the state will refund part of the tax on the product to the manufacturer, which is a common practice in the world. And because the mobile phone you buy enters the country through abnormal channels, it will also have less tariffs and some other taxes, and it will naturally be cheaper than domestic licensed goods.
