Very practical mobile phone tips

(1) The maintenance personnel shall inform you of important common sense and provide urgent tips such as when a mobile phone is about to commit suicide. This will make it difficult for the mobile phone to say goodbye to other people. :! When a mobile phone enters the water, please remember not to perform any button actions, especially Shutdown (when you press any action, the water will immediately follow the circuit board stream string), the correct method is to immediately open the external cover, directly remove the battery and force the power off directly. This prevents the motherboard from being attacked by water. This common sense is very important, so I would like to tell you how to make your mobile phone available for a longer time. Learn it! For future use! (2) do not use one cell phone signal When there is only one cell phone, do not use the message receiving mode. When there is only one cell phone, the launch intensity is more than 1000 times different .. Obtain a very important message from a professor at Jiaotong University, that is, when you find that the mobile phone reception is only one grid, you 'd rather stop talking or switch to a public phone. don't talk about it, talk about it, get it done, get it done, and get it done... Why? We all know that mobile phone electromagnetic waves have always been a worrying issue. the mobile phone is designed to maintain a relatively high quality of calls in areas with poor reception, which will enhance the electromagnetic emission intensity of mobile phones. when the received message is full and only one grid is left, the emission intensity is more than 1000 times different. the electromagnetic wave intensity is as high as 0.6 W (How strong is the W 0.6w? I cannot describe the negative effects on your head, but I can use two examples to compare them: 1. turn the volume of a small radio with a diameter of about 4 centimeters to the maximum and stick it on the ear. The noise energy is generally 0.25 W, less than W2. place the finger in front of the laser light with an output intensity of w (equivalent to the optical fiber network? D trunk line energy) in a few seconds you will feel burning. Can you endure these two conditions for a long time? Then, how do you confirm that the electromagnetic wave 0.6w is close to your ears? Before using your mobile phone, we recommend that you check the number of received message records for your health. It is also a good way to use the phone free! (3) how to bring the cell phone battery back to life :! When your mobile phone battery takes longer (memory effect or aging), will you buy another battery to replace it? Next time you encounter this situation, please save your money and tell you a very effective way to try: 1. pack the battery in a newspaper and wrap it in a plastic bag for three days in the freezer (the newspaper absorbs excess water. three days later, take out normal temperature and place it for two days. two days later, the battery will be charged and loaded into the mobile phone package for testing (80%-90% can be rescued). This message is provided by engineers of well-known battery manufacturers, according to the tested friends, the results are quite effective. the battery is useless, and the refrigerator is available to everyone. You may as well try it !) Is power-off on mobile phones? Or is it not long before the power is fully loaded? Don't worry, it's just a moment of "heartbeat stopped", as long as a small eraser will be able to return to life! After removing the battery, use an eraser to clean the contacts (Brass Sheets) on the battery and install them on the mobile phone ,? It's amazing! It actually got live! It's like a new one! It is really useful for your reference! (4) how to eliminate cell phone screen scratches :! Do you often encounter scratches on your cell phone screen and do not know how to handle them? Let us know a recipe for use .... (I saw it on TV a few days ago) Squeeze the right amount of toothpaste on the wet rag and then apply it evenly between the front and back of the scratch on the phone screen ..... you will find ..... the screen scratches on the mobile phone will disappear .... it's amazing ...!! What's more amazing... after a clean rag or toilet paper is used, the screen will become brighter .... Professor of big chemistry said: the principle of toothpaste is that it is only auxiliary supplies for brushing teeth, with friction (repair) and removal of plaque, cleaning and polishing the tooth surface, therefore, using it on the mobile phone screen will have the same effect. (5) how to set N alarm clocks: We all know that the 6270 standard alarm clock can be set from Monday to Sunday, but it can only ring once a day, I will give you a prescription, that is, to set a memorandum from the calendar, and then choose to repeat each day to achieve another "alarm ". The specific remedies are as follows: menu> Transaction Manager> calendar (select a day, and click "View" to see if there is no memo written in it) -- click "add" to select a memo and write the memo content as needed, the date can be selected for the current day, and the alarm clock will be selected with the alarm clock prompt. You can set the alarm clock time by yourself. The most important thing is to select a daily repetition in the repeat option, and you need to select a confirmation option for an indefinite repeat, the last step is to store the alarms. In this way, you can set two alarms. Likewise, you can say: you can set more than N alarm clocks every day as long as you don't bother to teach you how to identify refurbished mobile phones. Although the source of refurbished mobile phones varies, there is a common feature, that is, they cannot enjoy normal after-sales services like regular products. (6) how to identify and renovate mobile phones I will share my experience with readers on how to identify and renovate mobile phones. The so-called refurbished mobile phone is to collect the original movement, shell or outer packaging for repair or processing, and then as a new machine to sell mobile phones. There are many types, mainly from the following sources: 1. Old Machines with faulty movement circuit boards are repackaged and sold after maintenance or assembling parts. These machines have the most unstable performance; 2. After the normal old machine casing is processed, "beauty", or changed, it will be sold as a new machine; 3. Machines in informal channels are sold as new products after software refresh and repackaging. Generally, the stability of such machines is insufficient. Although the sources of these refurbished mobile phones are different, there is a common feature that they cannot enjoy normal after-sales services like regular products. I will share my experiences with readers on how to identify and renovate mobile phones. First look at the phone serial number (IMEI) The so-called phone serial number is like the ID card of a mobile phone. Because the IMEI number of each mobile phone is unique, it is generally used to determine whether a mobile phone is genuine. The identification method is as follows: when the mobile phone is in standby mode, "#06 #" does not include quotation marks. A string of numbers displayed on the mobile phone is the main board serial number, and you can write it down; remove the cell phone battery and check the string number on the white label in the two labels behind the cell phone body, that is, the shell string number. The other label is generally a network access license. Check whether the number is the same as the number listed above. Check the IMEI number on the mobile phone box and compare the three to see if they are the same. If the motherboard serial number is inconsistent with the chassis serial number, or the motherboard serial number is not displayed or a strange number or symbol, this machine is likely to be repaired or assembled by different parts, and cannot be purchased. If the three serial numbers are the same, and a network access license is added, this basically proves that the machine is genuine, but it cannot be absolutely affirmed, because the current unscrupulous merchants can fake everything, the motherboard serial numbers can be written in computers and software, fake serial numbers and network access licenses can be bought for a few dollars, for the sake of prudence, the verification should continue as follows. The second trick is to check the outer packing and instruction manual of the mobile phone. The packaging and manual printing of regular new mobile phones are exquisite, mostly for coated paper printing. The fonts and images are very clear and informative, while fake packaging boxes are mostly for simple imitation of Single-sided paper, the fonts and images are dry, rough, and the printed handwriting is blurred. Many non-formal channels have modified the specification or even copied it. There are also some refurbished mobile phones that use the original genuine packaging box and instructions, but after all, the machine is old, its packaging box must be worn out, the instructions must also have traces of use, pay more attention to the purchase and you will be able to find out. Third, check the inbound license. There is a watermark on the network license, the surface color is uneven, there is a deep and shallow, there is a thick and fine; and the fake is mostly copying, the surface color has not changed. If you cannot see it, you can also use the money detector to take a picture of the network access license. There is a real anti-counterfeit pattern that will show a red "cmii" pattern. While fake patterns are blurred. The real network access certificate is usually printed with a dot matrix printer, the number is clear, carefully look at the concave marks of the needle, and the false network access license is printed by a general printer, the number is not very clear, there is no dent. In general, it is difficult to fake a network license. After all, the equipment required for counterfeiting is relatively high in cost. In addition, you can query the Internet to verify the authenticity of the inbound license. Fourth, look at the mobile phone shell When you open a brand new mobile phone, you will obviously notice that the "key parts" of the mobile phone are all protected by the manufacturer's film, such as the internal screen and external screen of the new mobile phone, take photos of the phone lens and so on, because these parts will leave fingerprints as long as they are in contact. therefore, when you see the fingerprints on the new user's machine, do not listen to the seller's explanation. In addition, the dust and usage marks are also difficult to avoid, the gap between the mobile phone upper and lower shell, the gap around the keyboard, and charger slots are easy to "dirty, if you flip your phone's rotating axis, you will also find traces of use. Refurbished mobile phones generally use the shell is imitation of the original, or the old shell carefully polished, so the phone shell before and after the two parts are easy to appear closed tight, leaving a lot of seams, the identification method is to use the fingernails to try whether to insert the seams on and off the mobile phone. If it can be inserted, it is to assemble the shell. For mobile phones that do not have a shell to be changed, the merchant sprayed a spray like a detergent before the sale, and the old shell's surface immediately showed a frosted effect like a new machine, if the buyer does not check the case carefully, the illegal seller will be unable to pass the customs clearance, but it will not take long for the paint of the shell to fall off. When buying the shell, you must carefully observe the shell, because the merchant's craft is good, and there is no advanced equipment from the original factory, if you carefully check it, you can see that a small particle is dust, because the painting is not in the vacuum room. If it is a flip machine, you can also check the combination of the flip, because sometimes, even if the vendors make the machine surface better, these places will inevitably leave some dust marks. In addition, check whether the body screws are brand new and whether there are any traces of screwdrivers being screwed. It should be noted that many new mobile phones have an obvious sandalwood smell, while old phones and shell-changing machines do not have such a smell, or the smell left by working hours. 5. Watch mobile phone accessories If it is a new mobile phone from a regular manufacturer, there should be a full set of original factory accessories, at least one power and one charge. However, the accessories for refurbished mobile phones are generally incomplete or not from the original manufacturer. before purchasing a mobile phone, it is best to go to the relevant website to learn about the standard factory accessories, so as to prevent vendors from purchasing accessories. In addition, if there are scratches on the matching charger and earphone plug, then this phone may not be brand new. 6. Check the usage record. Check whether the game, text message, phone book, call record, and self-edited ringtone items on the mobile phone have been used and left behind. If so, there will be a very large rebuild suspect. In addition, if the mobile phone is automatically shut down or crashed frequently during normal use, you can say that the motherboard or software of the mobile phone has some problems.
