14 secrets you must know in your mobile phone.

14 secrets you must know in your mobile phone. People nowadays can't live without mobile phones. Mobile phones have become one of the necessities in our lives. Those of us who use mobile phones can learn more about the use of mobile phones. Here I'll show you the secrets that 14 mobile phones must know.

14 secrets you must know in your mobile phone 1 1. Do not end the call after 1 minute.

When we are on the phone, we are often glad that we finished the call just before 1:00, but this is not the case. According to a staff member of China Mobile, in fact, you call for one minute until 0: 55, so the call time from 0:55 to 1: 00 is actually two minutes!

2. Teach you how to eliminate scratches on your mobile phone screen.

Do you often encounter scratches on the screen of your mobile phone and don't know how to deal with them? Tell everyone a useful secret recipe. Squeeze a proper amount of toothpaste on a wet rag, and then evenly apply it to the scratches on the screen of the mobile phone. You will find that the scratches on the phone screen will disappear. It's amazing! Even more amazing, the screen of the mobile phone will become brighter after being wiped with a clean rag or toilet paper.

Its principle is that toothpaste is only an auxiliary product for brushing teeth, which has the functions of rubbing (repairing), removing dental plaque and cleaning and polishing the tooth surface, so it will have the same effect when used on the screen of mobile phone.

3. Invisible backup battery

Your mobile phone battery is low. To keep it in use, press the *3370# key and the phone will restart. After starting, you will find that the power has increased by 50%. 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.

I left the car remote control in the car.

Can you turn on the remote control of your car? 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. Someone has tried it personally, and it is very effective and amazing. )

5. Emergency situation

The emergency number that can be dialed by mobile phones all over the world is 1 12. When you find that there is no cell phone coverage in your area, and you encounter an emergency, it is correct to dial 1 12 with your cell phone, because your cell phone will automatically search all available networks and set up an emergency call. 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!

6. The mobile phone was stolen

There is a way that thieves can't use, hehe! To view the serial number of the mobile phone, just enter *#06# 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.

7. Don't wait until the battery is dead before recharging.

Generally, we have an idea that it is best to recharge the battery of mobile phone after it is fully discharged, which is basically the case, because most of the rechargeable batteries we used in the past are nickel-hydrogen batteries, which have the so-called memory effect, and if they are not fully discharged and recharged, the battery life will be rapidly reduced. 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.

8. Please don't answer the phone while the phone is charging.

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.

9. Don't use the mobile phone when there is only one battery left.

Compared with only one cell left, the transmission intensity is much 1000 times, so people who often speak mobile phones should pay attention. When you find that the reception intensity of your mobile phone is only one cell, you would rather hang up or switch to a public phone than talk endlessly, foaming at the mouth and endless affection.

Why? As we all know, the electromagnetic wave of mobile phones has always been a worrying problem. The design of the mobile phone will enhance the electromagnetic wave emission intensity of the mobile phone, so as to maintain a fairly high 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 effects it will have on your brain, but I can compare it with two examples:

① Turn up the volume of the small radio with a horn with a diameter of about 4 cm and stick it on your ear. The noise energy is generally 0.25W, less than 0.5W W. ..

② Put your finger in front of a laser beam with an output intensity of 0. 1W (equivalent to the energy of the D trunk line of the optical fiber network), and you will feel burning pain in a few seconds. Can you endure the above two situations for a long time? Then how can you be sure that 0.6W electromagnetic wave will be fine if it is attached to your ear?

10, 12593+ phone number = trap

Do you store the phone number of your foreign friend in the phone book in the format of 1795 1+ phone number-instead of dialing it separately-then the charge will be changed from 0.39 yuan per minute to 1.3 yuan per minute. I also checked it from 10086. Their explanation is that 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. Shenzhouxing users are 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, I wouldn't have been told about this charge at all.

1 1, the parasite of mobile phone charges.

The mobile phone is inexplicably set with useless text messages. I strongly recommend that you see if you have been recruited. The easiest way is to unsubscribe from the parasite who steals your mobile phone bill 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 short message to 10086, and a short message list will be automatically replied within a few seconds, showing which short message services you have subscribed to on your mobile phone.

Which SMS service providers deduct your mobile phone fee every month; Enter the number "00000" and send a short message to 18620 1 to unsubscribe from all short message services.

12, when the phone is flooded.

Please remember not to press any key action, especially to turn off the power (once you press any action, the water will flow away with the circuit board immediately). The correct way is to immediately open the cover, directly remove the battery, and directly force the power off to protect the motherboard from water. This common sense is very important, so I will tell you to make your hand work for a long time. Learn! In case of future emergencies!

13, How to bring the mobile phone battery back to life

When the battery life of your mobile phone becomes shorter (memory effect or aging), will you buy another battery to replace it? Please save your money and tell you a very effective method next time you encounter this situation. Give it a try:

① Wrap the battery in newspaper, then put it in a plastic bag and freeze it in the refrigerator for three days (the newspaper can absorb excess water).

② Take it out after three days and leave it at room temperature for two days.

(3) After two days, charge the battery and put it into the mobile phone for testing (estimated to save 80%-90%).

14, give your mobile phone CPR.

Does the mobile phone often run out of power? Or is it fully charged and then dead? I must wonder if the life of the mobile phone is over. Don't worry, it's just a temporary "cardiac arrest". You can bring it back to life with a small eraser. After taking out the battery, clean the contacts (copper sheets) on the battery with an eraser and put them back on the mobile phone. You will find it amazing. It really came back to life and looked like a new one. It is really useful for your reference!

14 secrets you must know in your mobile phone 2 secrets in Xiaomi's mobile phone buttons

1, power button

Introduction: The most commonly used physical keys are under great pressure because they bear the heavy responsibility of locking/lighting the screen. It is also the most worn button.

Main functions: power on, power off, restart *, light up and lock the screen. Add an explanation with an asterisk. Under MIUI, the switch of the notification bar is relatively simple. Long press the power button will pop up the menu of "mobile phone options"; When the notification bar switch is in single-page style, long press will drop down the notification bar. In addition, under the recovery (press the volume plus sign and the power button to enter when starting), the power button has the confirmation function.

Friendly reminder: the switch style of the notification bar can be modified in Settings-Personal-Notification Bar Switch. Select the desired switch and sort it to customize the switch.

2, the volume up and down keys

Main function: increase or decrease the volume. In the main interface, you can change the ringtone volume, in the call interface, you can change the call volume, in music, you can change the media volume … in the main interface, press and hold the volume-switch to mute mode. At the same time, it can also be used as a key to light up the screen, which is Settings-System-Key-Volume Key Wake-up. In recovery, it has the function of moving up and down.

Friendly reminder: Personally, I think the volume button is not as practical as the power button. Use the volume button to wake up carefully.

3, the meter key

Introduction: The intimate design of Xiaomi mobile phone, two-stage buttons, has the function of camera/shutter itself, and can also customize the function.

Main functions: press and hold the meter key to turn on the camera. In the camera, there are shutter keys and two buttons. Virtual press is autofocus and real press is shooting. In addition, detailed settings can be made in Settings-System-Keys-Metrics, which can be set as shortcut operation, shortcut switch or application opening.

Friendly reminder: My setting is quick operation-lock screen or light screen. I feel that this button feels good and I don't often take pictures. I occasionally use the guest screen lock button.
