Android can't pop up automatically.

First, quickly check the charging situation of the mobile phone

Method 1: Looking at the standby screen, it is well known that the Android system has designed the automatic screen locking function. When the mobile phone is not used for a period of time, it will automatically turn off the background light. If you need to activate, you need to press the menu button twice, but after the first press, the standby interface will be displayed, which will show the current battery charging situation of the mobile phone.

Method 2: In the "Status" option in the AboutPhone option of Android system, you can see the BatteryLevel option, which is the display of the current mobile phone charging situation.

Method 3: Check through third-party software. Because there is no such special software in Android system, if you want to check the current charging situation of your mobile phone in detail, use a third-party battery check software.

Second, teach you to set the input password invisible.

Friends who have used some applications that need to log in believe that when you enter the account password, the default display is the password you entered. To be on the safe side, you don't want people next to you to see your password. So how can I set the Android phone to be invisible to the password I entered? Teach you to set the input password not to be displayed.

The password setting is of course in SecurityLocation, so let's first press the menu key on the main screen interface and select the last item "Settings" in the pop-up advanced menu;

After entering the setting menu, slide the scroll bar down to find the classification of "SecurityLocation" and click Enter;

Find the password category in the security and location category menu, and then remove the check mark after the "Visiblepasswords" option.

Third, the market download failure solution

In fact, this kind of problem simply does not exist abroad. Only friends in China will encounter this kind of problem. This is because it seems that the Google server is blocked in China, so if we need services such as YOUTUBE, we can only "climb over the wall".

Setting static IP can solve your worries for netizens. This method was originally created by Android 123 and cooperated with Google's latest service. After dozens of Android phones, you can download the program normally.

First, we click "Settings-Wireless Control-—WiFi Settings-Menu-—ADBANCED" in turn, check "Use Static CIP", set DNS 1 to 8.8.8, and set DNS 2 to 8.8.4.4.

Yes, the method mentioned above uses Google's latest DNS service, and no other settings are needed after filling in.

Fourthly, another way to set the Droid ringtone.

When we set ringtones on other Android phones, we usually use third-party software (such as TongPicker). This setting method is a bit cumbersome, and you must start the program in the corresponding setting box to set it. Android 123 brings you the choice of using your own ringtone library.

Simply put, this method is to set the corresponding folder in the built-in TF card, and the folder must be set according to the specified name, otherwise the system will not recognize it. In this way, you can set the sound of incoming call ringtone, SMS ringtone, alarm and system prompt.

First of all, we need to create a folder named media in the root directory of TF card, set the audio folder in this folder, and then set other corresponding folders in the audio folder.

Among them, the folder where SMS ringtones are placed is named notification, the folder where alarm ringtones are placed is named alarm, the folder where incoming ringtones are placed is named ringtone, and the folder where system prompts are placed is named ui.

Once the folder is set, put the corresponding ringtone file in the corresponding folder. In this way, we can directly see these ringtone files in the settings of Android system and make a choice.

Fifth, the ringtone of the Android memory card folder is not displayed.

There are many ways to set ringtones for Android phones, but the most common one is to set several folders with specific names on the SD card, then put the ringtone files into the folders, and then use the ringtone setting method that comes with the mobile phone to view and select the ringtones in the SD card. Many netizens said that this method could not be used normally. After placing ringtones, these ringtone files cannot be read. What's going on here? How to solve it?

There are actually many reasons for this. Let me analyze the reasons and solutions for you.

The first reason is that the ringtone format is not supported. At present, the Android operating system only supports audio in MP3 and WMA formats. Therefore, audio in other formats must be converted to these two formats before it can be read.

Secondly, the set folder name is wrong, so be sure to read it carefully. The folder names set here are "Notice" and "Ringtone" respectively, and the first letter is guaranteed to be lowercase.

Then there is the problem of the card. Some memory cards have quality problems, and stored files will be lost automatically.

Finally, there is the problem of the ROM version of the mobile phone. Some netizens' self-made ROM is not optimized for SD card reading. After selecting the ringtone selection interface, it will take some time to appear in the ringtone selection menu of Android system.

Sixth, Android phones delete contacts in batches.

Sometimes we need to delete contacts, especially not all of them, but selectively. Can I only delete one by one manually in Android phones? This is too much trouble. If you have more, you can't finish it in half an hour. Is there any simple way?

Yes, there are two ways to delete contacts at present. The first way is to delete one by one on the mobile phone as mentioned above. Another method is to use Gmail account bound to Android phone to synchronize contacts to the phone. Conversely, contacts on Android phones can also choose to sync to contacts in Gmail accounts. So we can use the second method to quickly delete contacts in batches.

The specific operation steps are as follows: enter the Gmail mailbox bound on the Android phone on the PC, delete the contacts in the contacts, and then synchronize the contacts on the phone after deletion.

Seven, Android phone WIFI connection can not access the Internet.

Some users who use Android phones will encounter this problem. When the mobile phone is connected to the WIFI wireless network, it can connect to the wireless network normally, and the signal is very good, but it can't be used normally when using some software that needs network support (such as browser or market), and there is a big delay. What's going on here?

First of all, according to the usual analysis, this symptom is definitely not caused by a password error, because you can connect to the Internet, but there is a great delay. Therefore, the setting of WIFI should be problematic.

Then we went into the Android phone to check the WIFI settings, and found that there was nothing to set. It should be the setting of the wireless router. Entering the wireless router settings, I found that the wireless mode is set to mixed mode, but the built-in WIFI module of Android phones currently produced supports mixed mode. However, there may be problems in switching between network standards, so the wireless router can be set to 802.11g. Of course, 802.438+05438+0b is ok, but the speed is a little slower. Since then, the problem that WIFI connection cannot access the Internet has been successfully solved.

Eight, Android phone factory settings.

As an intelligent operating system, Android also has built-in functions of many other intelligent operating systems, such as restoring the factory settings necessary for each mobile phone. So how to set up an Android phone to correctly restore the factory settings?

First of all, it should be clear that the function of restoring factory settings is not often used, because if the consequences caused by misoperation are very serious, it is literally understandable to restore factory settings. All settings in the phone will be restored to the factory state, including the software installed on the phone, stored contacts, received information and Gmail. The bound Gmail account will disappear, and you need to initialize the settings and bind the Gmail account when you turn it on again. So this is a function that the mobile phone uses only when it encounters an unrecoverable error. So how to operate?

There are two ways to do this. The first explanation is as follows. First, enter the settings of the mobile phone, select SD card and mobile sdcardphonestoration, and then select the last one to reset the factory data.

The second method is to select Erase in recovery mode. When you start to enter the recovery mode, just press the Home key and the hang-up key at the same time.

Display lunar calendar date on the desktop

As a China person, we always refer to the lunar calendar invented by the ancients on holidays, not only because it can tell the solar terms, but perhaps it is our tradition in China. So can I display the lunar calendar on my desktop with my Android phone?

Yes, you can. You remember a component provided by Google called Calendar, which can be seen on PC***, Gmail and iGoogle. On the other hand, Android phones are closely related to various services of Google. Of course, this calendar component is no exception. It can synchronize the user's schedule and notes, and it will automatically synchronize when the Android phone turns on WIFI. In addition, the calendar on the mobile phone can add Widget to the desktop, but the lunar calendar information can only be displayed on the desktop after certain settings. The setting method is as follows:

Enter the calendar gadget on the Android desktop, press the Menu key to select the last item More, click "My Calendar", and then check the Lunar Calendar option.

X. View the battery details of Android mobile phone

In the process of using the mobile phone, you may feel that the standby time of the battery is getting shorter and shorter. Is it because the cell phone battery is aging? Then can I check the battery information that the mobile phone is using? It is possible to use a smart phone, but it is all achieved by installing some third-party battery detection software. If you use an Android phone, don't bother, because the phone comes with battery information. How to check?

In fact, the viewing method is very simple, just enter the engineering mode of Android directly, and the operation steps are as follows:

First, enter the dialing "dialer" interface of the operating system, and enter "*#*#4636#*#*" (without quotation marks) to quickly enter the engineering test mode of Android. In the "Test" menu, there are four options: phone information, battery information, battery history and usage statistics. Click the second item "Batteryinformation" to enter, and you can see the detailed information of the mobile phone battery, including information such as power level, battery state, temperature, battery material, voltage, etc.

How to modify the name of the desktop folder?

The desktop function of Android operating system is very powerful, which can not only block shortcuts of programs, but also place various Widget desktop components, such as music player and analog clock on the desktop of the system, all of which are considered widgets. In addition to the above components, the desktop can also block folder and contact options, which will make it easier to manage the classification of various programs and the use of shortcuts in the system. It's as simple as using a desktop folder on a computer. So can this Android desktop folder be renamed like a PC?

Sure, and it's convenient to change clothes. The following are the specific steps:

First, press in the blank space of the desktop, select the folder option in the new window that pops up, and then select New Folder in the advanced menu. Click the new folder on the desktop, open it and press the title bar of the folder, and the rename dialog box will appear. Write, rename and save it.

Twelve, how to check the historical running time of the program?

The Android operating system is powerful. Because of its open source, there is nothing to hide. Of course, all kinds of data in Android phones can be seen, but some data can't be seen in normal mode, so it must be viewed in engineering test mode. So how can we get into pattern of systems engineering?

In fact, it's very simple. You don't have to press any key combination at the same time, just dial in the dialing interface. Click the dialer on the main screen of the system to enter the dialing interface, and enter "*#*#4636#*#*" (without quotation marks) to enter the engineering test mode. At this time, you can see that the test interface appears, including four options: Phoneinformation, Batteryinformation, Batteryhistory and Usagestatistics, as shown in the following figure. If you need to check the historical running time of the program, you can directly click the last Usagestatistics to enter its classification, and select Sortby at the top as UsageTime. The list information listed below is the historical running time of each program.

Collection of general skills for Android system

As an intelligent operating system, shortcut keys and skills are essential. This website has also introduced many skills of using Android operating system before.

1. First, it is one of the most commonly used skills. Press and hold the Home key to bring up six recently used programs and put the current program into the background.

2. Turn the volume down to the lowest, and you will enter vibration mode and mute the ringtone in turn.

3. Long press the hang-up button, you can choose flight mode, silent mode and power off in the pop-up advanced menu, but it is worth mentioning that the quiet room here is completely silent, and there is no sound in the music box game.

Fourteen, Android phone WIFI problem set

At present, Android phones on the market are basically sent overseas, so they all have WIFI function, which is very convenient. In addition, because the Android system relies on the network to play its convenient and fast features, WIFI is also an indispensable part. So how to set it up?

First, press the Menu key in the main screen interface of the system, select the last setting, enter the Wirelesscontrols-Wi-Fi setting in turn, check Wi-Fi, and then turn on Networknotification, and the system will automatically enter the network search state. Wait a moment, search and click on the available network. If you have a password, enter it, and then click Connect.

In the daily use of WIFI, we often encounter some problems, such as being able to connect but unable to surf the Internet. These problems are probably caused by other reasons and can be roughly divided into two categories. One is the problem of program setting, which basically exists in the case of unequal passwords. The other is the hardware problem, which may be because the router firmware is old and can't send signals well. Users can rule it out one by one according to their own situation.

15. What if FormatSDcard is displayed when inserting TF card?

When inserting the newly bought TF card, "FormatSDcard" will be displayed. A prompt appears, so how to solve it?

In fact, this is a function that will only appear in the system version after Android 1.5. Just like inserting a new SD card into a computer with Windows operating system, you will be prompted to format it once. You just need to format the TF card according to the prompts. Of course, this is just a brand new card. If there is important information in the card, please back it up on your computer and format it on your Android phone.

When you select "OK", "Areyousureuwanttoformattechcard? The prompt "Alldataonyourcardwillbelost" means "Are you sure you want to format the SD card, and the data on all cards will be lost". Click Format to format the card. After formatting, the Android phone will automatically create a default folder.

Sixteen, methods to improve the speed of GPS search for Android phones

At present, the GPS chips used in T-MobileG 1 and HTCMagic mobile phones are all the third generation navigation modules of star provided by SIRF, but it takes about 30~50 seconds to find the stars in cold start than outdoors. Improving the speed of searching for stars has become an important topic. Since Android 1.5 firmware, A-GPS assisted positioning function has been added, which can shorten this time by only about 10 second. But it needs GPRS traffic assistance.

The principle of A-GPS is mainly to improve the speed of GPS satellite search through the assistance of server location information, but the traffic of GPRS needs to be about 5KB- 10KB.
