How to tell the quality of a mobile phone?

JASCO "teaches you to identify the quality of mobile phones, all kinds of passwords, maintenance and precautions." Press *#06# for \x0d\ first, and then a serial number will appear on the phone, which can be counted to the seventh and eighth digits. \x0d\ If your seventh and eighth digits are the following two corresponding digits, it determines the quality of your mobile phone. \x0d\0,2 or 2,0, it is a bad mobile phone \ x0d \ 0,8 or 8,0, it is a good mobile phone \ x0d \ 0, 1 or 1 0, it is a good mobile phone \ x0d \ 0, 0 means it is produced by the original company. It's a very, very bad mobile phone \x0d\ 1, and it has an invisible spare battery. I hope you like to press the following password on your mobile phone.

Have you ever felt the trouble of unlocking the keyboard of your mobile phone in the dark at night? In fact, you can touch the power button, and then the nightlight on the screen and keyboard will open, so you can easily distinguish the button to open the keyboard lock. \x0d\\x0d\ VIII。 Check the mobile phone status \ x0d \ x0d \ Operation instructions: # pw+ (primary code)+x # \ x0d \ (primary code) is a number of 10 (without brackets), and x is a 65438+. \ x0d \ x0d \ SIM card does not restrict information, which means that your mobile phone is unlocked. \ x0d \ \ x0d \ 1). vinchargerinputvoltage 8.4v 0.8 a \ x0d \ \ x0d \ 2). chrgctrlchargercontrolwm 32k Hz \ x0d \ \ x0d \ 3). xmicmicinput 60mv- 1V \ x0d \ \ x0d \ 4)。 SGNDSIGNALGROUND \ x0d \ \ x0d \ 5). xearearoutput 80mv- 1V \ x0d \ \ x0d \ 6). mbus 9600 b/S \ x0d \ \ x0d \ 7)。 FBUS _ rx 9.6-230.4 kb/S \ x0d \ \ x0d \ 8)。 fbus _ tx9.6-230.4kb/s \ x0d \ x0d \ 9)。 Nokia 9000/9000i \ x0d \ x0d \ 65438. 2) Display the software version number: * # 682371158412125 # The latest version is under telephone information \ x0d \ x0d \ 3).

When you press OK, a 2 character will appear at the top of the screen. At this time, the mobile phone can't dial out but can answer incoming calls. Cancel a re-operation and use it to achieve the effect of locking the machine. Enter the incoming call menu when there is no incoming call, and press and hold the function key for two seconds to enter the incoming call menu, which generally only appears when there is an incoming call. \x0d\\x0d\ XII, 6 1 10 Display the name on the standby screen \x0d\\x0d\ Select a least commonly used operation mode, usually pager menu 3-5, set personalized menu 3-5-2 and rename menu 3-5-3 as your own.

Precautions. \ x0d \ \ x0d \ Your mobile phone is low in battery, so you can use it. When this hidden spare battery runs out, you have to charge it. When charging, the invisible backup battery is also charged at the same time, and this method can be used next time the power is low. If the battery of the mobile phone is low, it is very useful to know this in an emergency. \x0d\\x0d\ 2。 Did you forget the car remote control? \x0d\\x0d\ Can you turn on the car remote control? If you can, you will find that one day you leave the car remote control in the car and the spare remote control is at home, so it is very convenient to have a mobile phone. Call your family's mobile phone with your mobile phone, and hold it one foot away from the car door. At the same time, your family will hold the remote control next to his mobile phone and press the unlock button on the remote control, so that your car door can be opened here. This method works no matter how far you drive from home. Seven people have tried it, and it's very effective and amazing. )\x0d\\x0d\ 3。 Emergency \ x0d \ x0d \ The emergency number that can be dialed by mobile phones all over the world is 1 12. You find that there is no cell phone coverage in your area, and you are in an emergency. What's particularly interesting is that you can still dial 1 12 even if your phone is in the keyboard lock state. Give it a try! \x0d\\x0d\ 4。 The phone was stolen? \x0d\\x0d\ There is a method that thieves can't use, hehe! To view the serial number of the mobile phone, just enter * # 0 6 # and the serial number of 15 will appear on the screen of the mobile phone. Every mobile phone in the world has a unique serial number. Record the serial number and save it. One day, if your mobile phone is unfortunately stolen, call the mobile phone provider and provide your mobile phone serial number, and they will help you shield your mobile phone, so that even if the thief changes the SIM card, it still cannot be used, and your mobile phone will become useless to the thief. If every mobile phone holder in the world does this, there is no point in stealing mobile phones. In Australia, the police even set up a database of stolen mobile phones. If you find your mobile phone, you can return it to you. \x0d\\x0d\ Necessary for daily maintenance: \ x0d \ x0d \ 1. Don't wait until the battery of your mobile phone is dead. \x0d\\x0d\ Generally, we all have an idea that it is best to fully discharge the battery of mobile phones before recharging. Basically, this is the case, because most rechargeable batteries we used in the past are nickel-hydrogen (NiH) batteries. The so-called memory effect of nickel-hydrogen batteries will lead to a rapid decline in battery life if they are not fully discharged and recharged. That's why we started charging with the last drop of electricity. Nowadays, most mobile phones and general IA products use lithium (Li) batteries, and there is no memory effect problem in lithium batteries. If the battery is completely used up before recharging, the chemicals inside the lithium battery will not react and the service life will be shortened. The best way is to charge it when you have nothing to do, and keep it in the best full state anytime and anywhere, so that your battery can last for a long time. This is the manufacturer's information, and I have tested it myself. \x0d\\x0d\ 2。 Don't answer the phone while the phone is charging! ! \x0d\\x0d\ The reason is that it is potentially dangerous to answer the phone when the phone is charging. There is a 3 1 year-old young man in India who works as a business manager in an insurance company. 10 days ago, he answered the phone when the phone was still connected to the charger. After a few seconds, a lot of current passed through the mobile phone, and the young man was thrown to the ground. When the family found out, their fingers were burned, their heartbeat was weak and they were unconscious. After being rushed to the hospital, the doctor pronounced him dead. Mobile phone is the most commonly used modern invention at present. However, we should also be alert to the danger of instrument death. \x0d\\x0d\ 3。 Don't use \x0d\\x0d\ when there is only one cell left. Compared with only one cell left, the difference of transmission intensity is more than 1000 times. So what? People who often use cell phones? Listen carefully, huh? I got a very important message from a mobile phone manufacturer yesterday, that is, when you find that the reception intensity of your mobile phone is only one frame, you would rather hang up or switch to a public phone. Don't be talkative, drooling, enthusiastic, endless? Why? As we all know, the electromagnetic wave of mobile phones has always been a worrying problem. The design of mobile phone will enhance the intensity of electromagnetic wave emission, so as to maintain considerable call quality in areas with poor reception. When the reception is full and there is only one cell left, the transmission intensity difference exceeds 1000 times. The electromagnetic wave intensity is as high as 0.6W (Watt). How strong is 0.6W? I can't describe in detail what bad effect it will have on your head, but I can compare it with two examples: \ x0d \ x0d \ 1) Turn up the volume of the small radio with a horn about 4 cm in diameter and stick it to your ear. The noise energy is generally 0.25W, less than 0.5W \ x0d \ \ x0d \ 2) Put your finger at the output intensity of 0. 1W (equivalent to the optical fiber network? You will feel burning pain in a few seconds. Can you stand these two situations for a long time? \x0d\\x0d\ Then how can you ensure that the 0.6W electromagnetic wave will stick to your ear? \ x0d \ x0d \ 4.12593+phone number = trap \x0d\\x0d\ \ Did you save the phone number of foreign friends in the phone book in the format of 1795 1+ phone number? Instead of dialing alone? Then the charge will be changed from 0.39 yuan per minute to 65438+ 0.3 yuan per minute. I also checked with 1860. Their explanation is, if it is stored in the phone book? The system will not recognize it. So you can't get the preferential tariff. You must press 12xxx directly on the keyboard every time. Are all users of Shenzhouxing like this? M-zone users, so is GSM. If you are a mobile user in China, when you know that China Mobile has set the following trap for you, you won't be surprised why your phone bill flies away like a wing. You can get a discount by using 12593+ phone number, but if you save "12593+ phone number" in the phone book of your mobile phone in advance, dial it out when you use it, and then dial it out. At this time, China Mobile will not admit that you have used the preferential dialing method of 12593, but will charge according to the direct dialing method. If it is roaming, the difference between the two charging methods can be as high as 7 times! I really didn't know how to express my anger when I learned about this charge. Later, when I called 10086 for consultation, if I hadn't asked this question on my own initiative, the lady whose work number is 6608 didn't tell me about this charge at all. \x0d\\x0d\ 5。 The parasite of mobile phone fee \ x0d \ x0d \ The mobile phone is inexplicably set with useless short messages. It is strongly recommended that you check whether you have been caught. The easiest way is to unsubscribe from the parasites who steal your mobile phone fee every month! China Mobile was forced to launch a new service on 3. 15. If you are a mobile phone user of China Mobile, enter the number "0000" and send a message to 10086. Within a few seconds, a short message list will be automatically replied, showing which short message services you have subscribed to on your mobile phone, and which short message service providers will deduct your mobile phone fee every month. Type the number "00000" and send a short message to 18620 1 to unsubscribe from all short message services. \x0d\\x0d\ 6。 Don't rush to make it 1 minute \x0d\\x0d\ When we make a phone call, we are often glad that we finished it just before 1:00, but this is not the case. According to a staff member of China Mobile, in fact, when you said 0:55. So the call time from 0: 55 to 1: 00 is actually 2 minutes ~\x0d\\x0d\ 7. Please remember not to press any key, especially the power off (if you press any action, the water will immediately flow away with the circuit board), \ x0d. \ x0d \ x0d \ This common sense is very important, so I'll tell you to make your hand work longer. Learn! In case of future emergencies! \x0d\\x0d\ 8。 How to bring the mobile phone battery back to life \ x0d \ x0d \ When the service life of your mobile phone battery becomes shorter (memory effect or aging), will you buy another battery to replace it? \x0d\\x0d\ Please save money to tell you a very effective method next time you encounter this kind of situation: \ x0d \ x0d \ 1) Wrap the battery in a newspaper and put it in a plastic bag for three days (newspapers can absorb excess water) \x0d\\x0d\ 3) Charge the battery after two days and put it in a mobile phone for testing. The news was revealed by an engineer from a well-known battery manufacturer. According to whether the battery is effective or not, anyway, the battery is almost useless, and everyone has a refrigerator, so friends might as well. \x0d\\x0d\ 9。 Give your mobile phone a CPR! \x0d\ Does the mobile phone often run out of power? Or is it fully charged and then dead? \ x0d \ x0d \ Do you want to know if the life of the mobile phone is over? \ x0d \ x0d \ Don't worry, it's just a temporary "cardiac arrest", and a little eraser can bring it back to life! \x0d\\x0d\ After taking out the battery, clean the contacts (brass sheets) on the battery with an eraser and put them back on the mobile phone. You will find it really amazing! It really came back to life! It looks like a new one! \x0d\\x0d\ is really useful for your reference!
