How to maintain the mobile phone to last longer?

Use and maintenance of mobile phones (1) Key points of using mobile phones 1 Keep mobile phones dry and clean: pay attention to the fact that rain, moisture and liquid contain minerals, which will corrode electronic circuit boards. Do not use or store the mobile phone in dusty or unclean places, which may damage its detachable parts. You can buy a leather case and put a protective coat on your mobile phone. Never use intensive cleaning agents or strong detergents to clean your mobile phone. Dust removal method for inner screen: prepare a roll of wide tape paper for box sealing, stick the tape paper on the inner screen of the machine, turn the shell upside down, stick a pressing piece inside the shell, tear off the tape paper and assemble the machine! How to deal with the mobile phone after it is flooded: In the daily use of mobile phones, it is still very common for mobile phones to get wet by water. For example, when washing hands, water drops accidentally splashed on the mobile phone, or when using the mobile phone in rainy days, the rain got the mobile phone wet. Once this happens, we must give first aid quickly. When the phone is flooded, please remember not to press any buttons, especially to turn it off (once you press any action, the water will flow away with the circuit board immediately). Because the inside of the mobile phone is composed of some circuit boards, if water seeps into the panel of the mobile phone, it may corrode the circuit or battery, which may cause the mobile phone to fail to work normally or even damage the mobile phone. Once the mobile phone is flooded, take out the battery immediately, and never turn it on immediately to understand the situation of the mobile phone. After removing the battery, don't use a hair dryer to treat it. Send it to a professional for disassembly and water treatment immediately. If it falls into sewage or corrosive liquid, it should be cleaned by ultrasonic wave first, and then dried before the next maintenance treatment. If the mobile phone can still be used after being flooded, it should be sent to a professional to prevent the circuit board from being corroded and irreparable. 2 Pay attention to the use environment of the mobile phone: First of all, don't store the mobile phone in an overheated or supercooled place: high temperature will shorten the life of electronic equipment, damage the battery, and deform or melt the plastic parts for writing. The mobile phone is stored in a cool place. When the temperature of the mobile phone rises, moisture will form in the mobile phone and damage the circuit board. 2. Don't use the mobile phone next to the program-controlled telephone in use: Don't use the GSM mobile phone next to the program-controlled telephone in use, because the interference between the GSM mobile phone and the program-controlled telephone is too great for both parties to hear clearly. Pay attention to the preservation of the mobile phone and its components: don't drop, knock or shake the mobile phone, which will damage the internal circuit board if it is treated rudely. Pay attention to keep the mobile phone and its parts and accessories out of the reach of children to prevent accidental damage to the mobile phone. 4 Don't disassemble the mobile phone without permission: Don't disassemble the mobile phone without permission. If the mobile phone or any of its components can't work normally, turn off the power immediately, and then take the mobile phone to a qualified maintenance agency nearby for repair. Non-professionals take apart mobile phones privately, which is very easy to damage.
