about mobile phone In terms of teaching people and fishing, many questions can not be answered directly, but can only be said as follows:

1. Whether the mobile phone is good, how about it, and whether it is worth buying: these are all questions about whether the personal needs can be met. Only when the hardware performance of the mobile phone can meet your needs, can it be necessary to start. You must know this answer when buying a mobile phone!

2. Whether the mobile phone hardware is good, how about the cost performance ratio, and what is the high cost performance ratio of the mobile phone: the performance depends on the processor, and you can directly find out on the official website of Anthare that the ranking of the mobile phone processor is low. In theory, the score of the processor is high, except the price! Different models of mobile phones can get scores in this way to compare who is higher!

3. How much is the mobile phone and when it will be launched: it is best to directly compare with three companies to negotiate. The price of mobile phones varies greatly. The selling price is not necessarily the price you will buy, but the time of launch must be subject to the official disclosure. Most online rumors are not accurate, especially some mobile phones are still concept phones.

4. What is the camera lens of the mobile phone, how about taking photos and taking selfies: taking photos is a relatively popular content at present. It is suggested to search the score of dxomark. At present, the highest score is Huawei's brand. Of course, many mobile phone models do not participate in this evaluation. In such cases, you can only judge by yourself from the relevant evaluation. Now the camera ability of mobile phones has generally improved, and there is no market for selfie cameras. Is it OK for most mobile phones to take selfies, but the photos taken are different from real people, I really don't know how to say! Of course, I have to spend more time to understand the information about camera hardware. What kind of lens is better than what kind of mobile phone imaging sensor is? Now Guizini's imx series sensors account for most of the market!

5. Configuration of mobile phone (including screen, processor, storage memory, camera, color matching, battery capacity and endurance, several versions, etc.): It is recommended that these information should be subject to the official information, because before the mobile phone is officially released, the rumored information should be at least referred to, but it is just the consumers' desire, and it is useless to understand! Of course, if you often know the official website of Anthare, you can roughly know when the mobile phone uses what processor, and the screen must be the current popular choice. Go to learn about these systems once, and no matter how the mobile phone is released in the future, it will change forever! In fact, the color matching does not affect the performance. I don't care about the so-called small content. In terms of batteries, the mainstream of mobile phone batteries is about 3000mah. At present, the battery material has not changed, and it is estimated that it will be doubled to 6000mah, which will not change the possibility of multiple charges in the next day when the mobile phone is heavily used.

6. When will the price of mobile phones be reduced? Generally, it will be three months after the release. I'm afraid the fierce competition will be much earlier!

7. Mobile phone quality: This is a false proposition. Any mobile phone has to be repaired. The main reason is personality! Generally, the after-sales service of mobile phones with large brands is good, which is an important guarantee of quality!

8. 5g mobile phones: 2019 is the first year of 5g mobile phones, and 5g mobile phones will be launched in large numbers soon. At the initial stage, 5g mobile phones may start at a price of nearly 10000 yuan, so we can see whether 5g is supported by the price. Of course, if not, it can also be compatible with 5g networks, and 4g is not too slow to use under 5g.

9. Where to buy the mobile phone is cheaper, when to buy it, when to reduce the price: this is generally the rush purchase on the official website. It is much cheaper when there are activities on the website. It is hard to know where to buy the mobile phone is cheaper. The more you buy in the future, the cheaper it will be. But buy early and enjoy early, it depends on your personal needs!

10. How long can the mobile phone last? Most people change the mobile phone every 2-3 years, so the physical life is unknown. A good maintenance can last a long time.

11. Mobile phone fast charging, wireless charging, and charging failure: mobile phones now support at least 5v2a fast charging, and the mainstream generally supports 18w fast charging. These individuals don't follow the trend! Because individuals often use it while charging (it is necessary to use a charging belt), they feel the need for fast charging is average, and they are even less interested in wireless charging! Of course, only high-end mobile phones can support wireless charging at present. Whether it is supported depends on the price of mobile phones. If the phone is unable to charge, it is recommended to replace the charging data cable first. If the battery is not charged, it is unable to charge, or try to find a high-power charger. If it can charge, replace it with the original one and continue to charge to full! If you can't, ask someone to repair it, or the battery has already gone!

12. Mobile phone system problem: The current mobile phone is nothing but Android and Apple. Is it easy to use? Generally, the system of mobile phones with large brands is relatively well optimized, such as Meizu, Xiaomi, Huawei, etc. According to the rules, Mijia's system is advertising and discounted!

13. Mobile phone signal, network speed: Mobile phone signal, network speed mainly depends on the network coverage strength and degree of the selected sim card service provider. If mobile phone can dominate the content of the signal, roughly the telecom service provider will not spend money to set up a base station!

14. Mobile game, stuck or smooth: the game depends on the performance, and the performance depends on the processor. It is mainly the processor performance that determines whether the game requirements can be met! Of course, under the same processor, the operation memory size will play a role. If the processor capacity cannot meet the game's hardware needs, this card is Sister Wu's business! However, if the ability can be met, and if you encounter a jam, you can only say that you need to learn to manage your phone well and release the hardware performance for game needs.

15. Mobile phone waterproof problem: most domestic phones do not support waterproof, and the waterproof of domestic phones is relatively poor, probably because Chinese people do not like to take mobile phones to the bath! It depends on the waterproof level of the mobile phone. At present, the IP68 level is the highest level under a certain standard. Mobile phone support will definitely boast. If you don't dare to boast, you don't need to count on it. It is either too low or not supported.

16. Advantages and Disadvantages of Mobile Phones: In fact, mobile phones are selected according to needs. Being enough to meet the needs of use is an advantage, not a disadvantage! The needs vary from person to person, so the advantages and disadvantages are not the same.

17. Mobile phone refresh, update and upgrade: mobile phones are generally recommended to be upgraded according to the official push, and it is necessary to consider downloading the official online refresh package to refresh! If it refers to root, it must be supported by some tool software vendors. Generally, before root, understand the consequences and prepare the official wire brushing package to prevent accidents.

18. Mobile phone projection and connection to computer TV: This can be used by tools such as projection masters, and the connection to computer TV can also be made through appropriate data lines, such as computers, mobile phone drivers, or one of the keys.

19. Mobile phone power saving, extended endurance, energy saving mode and other issues: open the power management software of mobile phone, and through understanding the power consumption of software and hardware, make targeted adjustments, and manage the background bootstrap program is a major way! But these are not as effective as using the power bank! Energy saving mode Each mobile phone brand has its own way, but whether it is willing to use it depends on people.

20. Mobile wallpaper replacement and dynamic wallpaper settings, ringing tones, etc.: Mobile phones provide wallpaper and dynamic wallpaper settings or related themes, of course, it will be easier to use wallpaper or dynamic wallpaper APP directly! In the same theme, there are ring tones. Except for Apple, it may be troublesome (which may need iTunes to handle), Android should be relatively easy.

21. The phone has no sound, unclear calls, phone recording and other problems: in general, when these problems occur suddenly, you'd better restart the phone to have a look! If the restart is invalid, please find someone to repair it for you. In case of hardware problems, it can only be repaired! Of course, you can consult the network service provider in terms of calls! However, some countries do not allow the privacy of telephone recording, so some imported mobile phones do not support it!

22. Screen capture of mobile phone: The simplest way to take a screenshot is to use the volume down button+power button of Android mobile phone.

23. Mobile WeChat dual opening: At present, most mobile phone systems directly support WeChat dual opening. If not, the hardware performance is enough to directly use the next dual opening software!

24. Mobile phone screen shattering, screen changing, touch failure, phone changing and other problems: when buying a mobile phone, you should consider buying screen shattering insurance. Personally, you will not consider it, but you will definitely buy a silicone cover to reduce the risk of screen shattering! If you buy, you can officially change the screen for free if necessary! Now the merchants provide 7 more days for no reason to return or replace the mobile phone. If there is a problem with the mobile phone, the first time to consult the official after-sales service for rights protection! I'm afraid there are many reasons why the mobile phone does not work properly after being used for a certain period of time. Restarting the mobile phone does not improve, and if the machine is relatively new, it is recommended to send it to maintenance!

25. Shooting vlog: This is not a problem, as long as you are willing to have a camera, of course, the effect depends on the grade of the mobile phone!

26. The problem that the mobile phone cannot be unlocked by fingerprint: this is not a problem. As long as you are the first owner of the mobile phone, you can reset the fingerprint settings directly if you encounter this problem!

27. Mobile phone's body capacity and extended memory: Android phones rely on transport storage, and transport storage of appropriate size is very important. As for the body memory, you can choose according to your own needs! Extended memory should not play a big role now. Most mobile phones share the design of SD memory card and sim card slot. Of course, there are three card slot mobile phones with 2sim card+sd card slot! Personally, this is not an important part of choosing a mobile phone, just enough is good!

Android system mobile phone (Some contents are also suitable for Macintosh) Some general problems:

1. Developer option: set~about mobile phone~version number~connect for 7 times~and then it is OK without saying that Sesame will open the door.

2. USB debugging: After the above is completed, return to the upper menu to see it.

3. Restore factory settings: Set~Other settings~Backup and reset~Restore factory settings~OK, or download the official version of the wire brushing package, if any, the wire brushing is more thorough.

4. Battery percentage: Set~Battery~Display remaining power percentage~Check OK! Or, set - other settings - battery - display remaining power percentage - check OK!

5. Mobile phone root: All of them are network search root tools. If you see which statement supports your mobile phone model, you can download it and try it at home, or find some tools, which may not be successful or can be solved at one time. Generally speaking, backup the official version of the mobile phone's online package before root. If it fails, it is recommended to immediately return to the official version of the system for the next attempt. In addition, some mobile phones have hardware level anti root. Think twice before you start, and current mobile phones do not need root very much.

6. Mobile phone swiping: if it refers to root tool, it should wait for each root tool manufacturer to launch it. If it refers to system firmware package, of course, it will be downloaded from the official website after it is pushed and released by the official brand manufacturer.

7. Uninstalling system applications: This is not recommended and requires root. Currently, mobile phones do not need root. The accompanying software generally supports uninstallation, and those that do not support it can also be frozen. Neither can be uninstalled or may cause some instability.

8. System update: It is generally recommended to update the system at the first time for new mobile phones. Normally, updates are mainly bug fixes, especially when updates are launched frequently.

9. Battery life of mobile phones: depending on the battery capacity, the life time of most mobile phones at present is 3000mah, and the difference is not more than 1000mah, which means that the life time difference is less than 30%.

10. Mobile Internet access, signal and speed: normally, it depends on the strength and extent of network coverage of the selected SIM card service provider. In theory, mobile phone manufacturers do not plan to create a machine that accepts signals to criticize, so they do not need to consider these problems under normal circumstances. In case of encountering these problems, it is only an example at most! That is to say, if you feel slow in accessing the Internet, you can give priority to the Internet service provider for consultation!

11. Mobile phone screenshot: For Android phones, the simplest way to take screenshots is the volume down button+power button.

12. Headphone jack problem: There is a small piece of spring in the headphone jack. Insert the headphone spring under pressure to start the headphone mode. Pull out the headphone spring to reset and exit the headphone mode. If the shrapnel does not reset, this problem will occur!~~ It is said that blowing vigorously on the headphone socket has a miraculous effect, or it can be repaired by repeatedly plugging and unplugging the plug. If it is not possible, it is not difficult to change the socket.

13. Connect to the computer: Normally, the data cable is directly connected to the USB port of the computer. You can download the official version of the cable brush package, which contains the relevant mobile phone model drivers. When the computer is installed, the mobile phone data cable can be accessed to identify and manage the computer.

14. Activation: Android phones generally have no activation problems. If there is an official activation tutorial provided by the brand, it is.

15. Wallpaper and dynamic wallpaper: Android system generally provides wallpaper and dynamic wallpaper settings. Of course, if you are not sure, you can download some wallpapers directly or install and use dynamic wallpaper APP.

16. Most of the settings of Android ringtones are: settings~sound and vibration~select the content to be replaced~select the appropriate ringtone! Or with the help of some APP applications.

17. Mobile phone heating problem: Under normal circumstances, check the power consumption of mobile phone software and hardware with the help of power management software, make targeted adjustments, and reduce the residence of background programs. Of course, if the abnormality is serious, you should directly contact the dealer for after-sales maintenance.

18. Call recording: If the brand is not prohibited, you can choose to record in the call interface!

19. Double opening of WeChat: At present, most mobile phones, as long as they are above the mainstream level, support the double opening of WeChat. Even if the system does not support it, they can also use third-party software to support it.

20. Idiot startup problem: search the button on the mobile phone. There is a semicircle and a vertical button that is the startup button. You can press it to have a look.

21. Dual card switchover problem: As long as dual cards are supported, the icon of data traffic can be seen in the drop-down menu. Click to select other telecom service providers. If the switchover is not possible, disable the available SIM card to see whether the data traffic of other service providers can be used!

22. Which is better for mobile phone photo software and photo skills? It is recommended that you try to choose the official video software provided by the brand, and don't use third-party software indiscriminately! As for the skills, be honest and familiar with the functions of these video software.

23. Who has the best performance of mobile phones? The problem of Carton: the ability of the processor depends on the game and the card! The capability of the processor determines the performance of the mobile phone, which can be learned from the Anthare website. At present, it is roughly classified as:

① The 1000 yuan machines with Snapdragon 636 processor and below, which are roughly in the range of Snapdragon 625 processor, belong to the mainstream, but don't be too demanding. Most mainstream games can be played, and the daily needs of this class of machines are smooth enough.

② With the Snapdragon 660 and the Snapdragon 710 processors, as long as you don't need to be too extreme, almost any game can be quite smooth, and of course, there is no problem with daily applications!

③ For machines equipped with Snapdragon 835 processor, few games can embarrass them under almost extreme requirements, let alone daily needs.

24. Mobile phone return and replacement: Chaotian now supports the return and replacement of new machines within 7 days without reason in most cases. After all, there is no answer to the quality problem. So in case of a problem, as long as you are not sure that it can be solved, you should consult the staff of the after-sales service center of the brand merchant at the first time. This can effectively avoid the economic losses caused by quality problems. Of course, if it is caused by personal factors such as water ingress and broken screen, it is necessary to pay the maintenance fee (the figure depends on the situation) without purchasing the corresponding insurance.

25. At present, most domestic computers are modified and optimized based on a version of Android system, which is not different in essence.

26. Mobile phone's body capacity: Android phones rely on transport and storage. Proper transport and storage is very important. As for the body memory, in addition to knowing the type of memory, you can choose the capacity according to your own needs. Too large is a waste of space. Many people can't use so much space.
