Exclamation mark on the phone. What do the icons on the phone on different models mean, their types and interpretation What does the red exclamation mark mean on android

In this case, put on charge for a couple of hours. Then, hold the button off for 15 seconds (or press reset). Wait about 15 minutes for the tablet body to cool down (the back cover may get warm when charging). Now try to turn on (3-5 sec button on) and wait 2 minutes.

Please accept my condolences, because if you are reading this article, then your Android tablet has stopped turning on. The reasons can be "iron" and "software". The first reason is the physical inability to turn on due to damage to the battery, board, cables. The second is that someone screwed up the OS on the tablet, and due to the fact that it got crooked after, or some freshly installed program turned out to be extremely incompetent, the device cannot “start up”.

Tablet won't turn on at all

1. Remember the last time you charged your electronic friend. One of the most common reasons is a tablet fully discharged. In this case, even if you put it on charge, it should take some time (sometimes up to 10 minutes) when the tablet has enough power to turn it on. Sit next to the patient, and with a break of one minute, hold down the power button for a long time until the screen lights up. And yes, you must be sure that Charger working. If there are no changes, check on another device if the charger works, or change it. If you are interested, then you need another article.

2. Remember, maybe you gave a tablet to a child? Perhaps the baby slammed the screen against the corner of the crib with all his might, and damaged the display. In this case, the tablet itself can work, but the screen will have to be replaced. The situation is the same if the tablet s landed from a height of one and a half meters on asphalt or a tiled floor. On your own, you can do little to help him - you can only sympathize with the poor fellow. Usually, a damaged screen is indicated by visible mechanical defects, or the absence of an image when turned on (only the backlight can be seen instead, and even then not always).

3. The tablet did not fall, did not hit, but there is no image? Unlikely, but still: perhaps the video adapter has come kaput.

If your tablet still has a warranty, then it's stupid to fix it yourself. Take it to the service center and don't worry. Of course, you can download schemes on the Internet and try to fix it yourself or give it to a friend, but it’s better not to do this.

Tablet turns on only halfway

A software failure is to blame for everything, and only he. In such cases, we observe the display backlight turned on, and then an endless download (ANDROID is constantly shimmering), or we see an image with a broken green robot.

This may be due to:

1. Incorrectly installed or crookedly working games, programs, launchers.

2. Forcibly terminated system processes that ensure the stability of the operating system. This can easily happen if you "killed" system process through some sort of task manager (or dispatcher), or third party program"battery saver" Trust me, this happened to me once.

What can be done in such a situation?

There is a chance to "revive" the tablet by resetting its settings to factory settings. It is done with the help of Hard Reset, and it is better to google how it is done specifically for your model. Especially if you have a tablet from a Chinese manufacturer. I highly recommend that you read the instructions for hard reset on various devices. Briefly describe general principle, most likely you will need to do the same:

Turn off the tablet
We take out the memory card and SIM card (just in case)
Hold down the volume up key ( and for some it is a decrease!) and the power button for about 10 seconds, the time is also not the same for all tablets.
The tablet should vibrate
A menu appears. Select the item with the volume and power keys Settings. Further - format system
Choose reset android , the tablet will reboot
All data and settings that were in the device’s memory will be erased and returned to the factory settings.
Don't be scared if you don't succeed the first time, it mostly works out the second :)

If this instruction didn’t help, try using the advice on a hard reset from the commentator Dima in the article, you can not look for the advice itself in the comments, I added it to the article. It also helps to bring the device back to life. And how to restore the tablet after an unsuccessful firmware is written.

Just in case, an English-language video instruction on a hard reset for Acer tablet Iconia Tab A500:

If a lying Android with a red exclamation mark appears

In many, I noticed in the comments, everything ends up like in the picture, or something like that:

This is the stock recovery mode (if you are wondering what it is), and there is nothing wrong with it and you should not be afraid of it. Moreover, you can − ClockWorkMod Recovery. If you see it, it means it works, which is good. You got into it because you entered the wrong combination for a hard reset, and I warned that it is not the same for all tablets. In this situation, you can press and hold the power button until the tablet turns off and try again, or just wait 5 minutes until it turns itself off and repeat the process. Try again, in extreme cases, you can just reflash.

fastboot mode

Sometimes, when trying to find the right combination, users end up in Fastboot mode. In such a situation, we observe the lying “Android” with an open belly / belly, but without an exclamation point. An example of such a menu for Nexus 7 (2013) in the photo:

If you got here, then use the volume buttons to select the item Restart bootloader and press the power button to confirm your selection. Perhaps this will help you load a tablet that has not been turned on before.

In general, it is useless to advise something specific here, since each model has its own pens. For some tablet models, you just need to press the Home button if a lying Android with an open belly appears - and a menu will appear in which you can choose to reset the settings. And for some - simultaneously press the increase and decrease the volume. And wait.

If the phone does not turn on, for example, after flashing, you can try the following steps:

Turn off the device by pressing the power button for a little over 10 seconds
Press Volume Down + Power, we get into Fastboot mode
Select the Recovery mode option with the volume control buttons, confirm the selection with the power button
Android will appear with exclamation mark. Then press the Power button, and then press the Volume Up
Select wipe data/factory reset option
Select reboot system now

If the Android robot lies with an exclamation mark, it means that most likely you have conducted an unsuccessful experiment with the device software. Perhaps you have installed some broken the program that led to fall android))

Do hard reset by selecting Wipe data / factory resetquot ; in the engineering menu. Depending on the model of your smartphone, go to engineering menu can be done as follows:

try the combination home, power and volume down key.
if the home touch, most likely a combination of buttons power and volume down.

The combination should be pinched with your fingers and held until the screen displays service menu. Then select the corresponding menu item by moving in nm by pressing the volume buttons.

After you select Wipe data / factory resetquot ;, several lines will appear on the screen and the question Delete all data from your device? Click yesquot ;. Now the device's memory is being cleared. After that, the device will reboot. If this does not happen automatically, you need to select the menu item rebootsystemnow. After the reboot, the device, in theory, should work normally again.

But the price for this is the loss of all data, and ALL of them - including all contacts, photos, sms and all applications ever downloaded.

For this reason, you should always regularly synchronize your smartphone with Google through your account, since almost all data can be restored in this way.

If rebooting through the engineering menu did not help, only a complete software replacement will help. It can be done by flashing by connecting a smartphone via USB to a computer or using a flash card through the engineering menu. Remember that flashing is a risky business. It is imperative to follow all the instructions exactly, otherwise your device may die finally. In any case, be sure to raise all the information on the firmware on the Internet so as not to make mistakes. Good luck to you!

Make a flashing, it only helped me

Perhaps the tablet spontaneously entered the Recavery mode or the engineering menu. If God has mercy and after rebooting, a normal download will take place, then some application can cause such an incident (sometimes it occurs when you get root rights) If again there is interference, then it's bad business with the firmware, only in the service for flashing.

You may have done something with the software on your tablet before. Most likely, they installed some kind of buggy program and this led to such unpleasant results. The first thing you can try to do yourself is to reset the tablet to factory settings. If this does not help, then reflash it. If you cannot do it yourself, then take it to a service center. They will definitely help you there.

This happens not only with tablets, but also with smartphones.

Something happened to your software.

Try to reset all settings on the tablet to factory settings (Hard reset).

You can read more about hard reset here.

In most cases, this will help you.

But like everything else, AT YOUR OWN RISK!>

After an unsuccessful attempt to make an android backup with a built-in robot application on its side, with an exclamation mark and a ripped belly! On the Internet, just play with the volume rocker and the power button to enter the menu.

The solution was to remove the battery for a couple of minutes, and insert it again. And everything WORKS!!! The system check did not find any failures. All settings, except for the clock, profiles and files, are in place!

But like everything else, AT YOUR OWN RISK!>

The recumbent anroid blinks, under the inscription no commands not one so-called reset by commands POWER home +, - there is no response, it just turns off, the screen lights up, as when loading and again returns to dead man does not turn off

Before that, three keys were simultaneously pressed Homequot ;, Volume - and the off button? It looks like you have entered the Recovery Menu of the tablet. There should be an item Reboot or Rebooting - tap on it. Or you can do a hard reset in the same place, while all the settings will return to the factory settings. And for the future, I recommend that you go to this forum, where you can find information on the tablet.

You have a crash, an error in the program. To get started, press the Searchquot ;, then Rebootquot ;, reboot. Usually in such cases a reboot helps. If this does not help, you need to contact the experts. Might need a flashing.

Stripes on the phone screen are a very common problem. The main trouble is that such a malfunction can appear at any time: on the day of purchase or after several years of use.

However, despite the frequent appearance of the problem, there are device owners who do not know how to solve it.

What does the defect look like?

The main thing to remember is that the display does not lose performance after a malfunction is detected. But this is not a reason to leave the device in such a state, because only its owner suffers from the incorrect functioning of the smartphone. If stripes appear on the phone screen, the image quality drops, so reading and watching movies will have to be excluded (few people like to "break their eyes"). That is, the presence of such a device will no longer make sense.

The defect manifests itself as a distortion of the content on the display. It ripples and goes in stripes (horizontal or vertical) of different colors: from black to iridescent tints.

Classification

In this section, you can indirectly find out the cause of the breakdown, but it will be rather inaccurate. However, it's worth a try.

For example, colored and white stripes on the phone screen are often a sign of mechanical damage to any component of the display or a loose fit of the cable into the groove.
Black lines signal the need to replace this part of the smartphone.
Colored ripples indicate a problem with the controller.

However, without opening the case, such "diagnoses" do not have confirmation, so either your own hands or service centers can help here.

How does the defect appear?

This section is also important, because it will make it clear to which part of the device (hardware or software) the malfunction belongs. It's pretty simple here:

If the stripes on the phone screen appear only when you launch a specific application or make any changes to the settings and files of the device, then the problem is the failure of the operating system.
When the lines go across the display after mechanical interference, damage, or when touching the touchscreen, we can safely talk about problems in the hardware itself.

After determining the type of malfunction, you should proceed to methods for solving it.

Stripe on the phone screen: what to do?

If the problem is caused mechanical damage, that is, there are two ways: take the gadget to a service center or disassemble it yourself. In the latter case, you should look for a master class in video format, which will show you how to open the case and get to the display. Next, you will need to carefully examine this part of the gadget to understand the extent of damage.

If the problem is only in the loose entry of the cable into the groove, then it is enough just to fix it, and the stripes on the phone screen will disappear. But in the case when it or the controller (microcircuit) is damaged, there is nothing left but a complete replacement of components.

At software failure the situation is usually corrected by a hard reset (a reset, during which all personal data is deleted, it is recommended to save before performing important files) or cleaning smartphones from viruses. Although the first method is more reliable, since many OS protection programs do not see the pest.

Multi-colored stripes on the phone screen - not yet a sentence

Even the most reliable technology fails from time to time. Sometimes mysterious defects can appear on the display of a smartphone or tablet. If you notice that a stripe has appeared on the phone screen, what should you do?

This is a fairly common breakdown, so you should know what are the causes of the defect and how to fix it. We list the causes of problems by the frequency of their occurrence:

Loop contact failure.
Crack in the display matrix.
Software failure.
Excess load in the system.
Wetting.

And by repairing possible damage yourself or with the help of a service center, you can continue to use your smartphone to communicate with friends and work colleagues and use health applications on your gadget.

The display cable has moved away from the connection socket

Most probable cause the fact that stripes appeared on the phone screen - a violation of contact with the cable due to a blow or a fall, while there may not be visible damage on the display or case - cracks, spots or zones that have changed color. Also, the cable can move away with sharp shocks and shaking.

If the contact goes off, you should contact the SC to fix the problem. But if you consider yourself an advanced user and think that you can restore the functionality on your own, then just press on the cable so that it fits snugly into the socket connector. However, care must be taken when disassembling the smartphone - you should not touch neighboring connections or "alarm" other miniature and sensitive elements.

Please note that self-opening the smartphone removes it from the warranty!

In very rare cases, damage occurs within the cable itself. Then it is necessary to carry out a complete replacement of the part. Its cost is low, as are the prices for the work of a specialist in its installation.

Crack in screen matrix

Such a defect often occurs during falls. Visible white, black or red stripes on the phone screen occur when the matrix and glass are damaged. In this case, cracks appear that can be determined by touch.

There is only one repair method in this case - screen replacement. Its price, unfortunately, is quite high, it consists of the cost of the spare part and the work of a specialist and is determined by the service center.

Software failure

In some cases, ripples or stripes on the phone screen occur due to software failures. Sometimes unnatural color spots appear, images overlap. Such defects can be caused by a virus, a bug in recently installed software, or incorrect update firmware.

The fix method is to reinstall the software or reset to factory settings. A more radical way is to restore the settings in service center. Firmware for some can be found on the pages of our website.

Intermittent freezes with image distortion

If defects appear intermittently and are accompanied by a program freeze, they are associated with overheating of the processor or video chip. The game is paused, simultaneously appear on the phone screen.

Today on various forums you can find several ways self fix the indicated defects. But if you are the owner of a smartphone with a guarantee, we recommend that you contact an authorized service where devices from the best manufacturers are serviced.

Defects associated with getting a smartphone into the water

If the reason for the appearance of streaks or stripes is obvious and is associated with the device getting into the rain, shower or puddle, the repair should begin with a shutdown. Then remove the battery, disassemble the case and dry all the parts.

If after drying and turning on the stripes or ripples have not disappeared, you will have to contact the service center.

If an android with appeared on the screen, this means that an unsuccessful experiment was carried out with the device software. Perhaps this happened due to the installation of an unlicensed program or after switching from the original firmware to custom.

Hard reset

This action is carried out in the engineering menu of the device and allows you to return the smartphone or tablet to its original settings, which is very useful when the android lies with an exclamation mark. A special engineering menu is called up by pressing certain buttons, but there are some difficulties here. Models different manufacturers keyboard shortcuts are different. There is a certain sequence in calling the engineering menu.

The device must be turned off. It is best if the battery is fully charged. For most gadgets, the following button combinations are suitable for calling up the menu:

The volume down key (or volume up key) is pressed and held together with the power button.
Both volume control keys are clamped and held, and then the power key is pressed.
At the same time, 3 buttons are held: the main screen, adding volume and power.
The Home key is pressed together with the volume control key down, then the power key is pressed. You must wait until the manufacturer splash screen appears and release the power button. After the robot image appears on the screen, you can release everything and wait for the engineering menu to appear.
Press and hold the power button for 2 seconds, then hold down the sound control keys and the power button, hold until a special menu appears.

After that, the gadget will either restart and restore the factory settings on its own, or an engineering menu will appear. For your information, in this mode, the touch screen does not work, all menu navigation is performed by the sound keys, and the selection button is the power key or the Home button. You must select the item "Wipe data / Factory reset".

Several lines will appear on the display and the question ("delete all data from your device?"). You must agree, after which the device's memory will be cleared.

Reset across devices

On smartphones and tablets manufactured by Samsung, the engineering menu is entered by simultaneously pressing 3 buttons: the gadget's main screen call key, the volume up key and the power button. Resetting to the original settings is done using the Wipe data / Factory reset item and then rebooting.

HTC devices, when an android with a red exclamation mark appears on the display, can be brought back to life by pressing and holding the power and volume buttons. When Warning appears on the display, you can release everything and press the volume up key. On some models, while holding the volume down button, press the power key and hold until the android robot appears on the screen. After it appears, you can release the buttons and hold down the volume key again. A menu will appear in which you need to select the item "Restore initial settings».

On Acer smartphones, resetting the settings is done by pressing and holding the volume up key and the power button. A menu will appear on the screen where you need to select the Recovery Mode item and press the volume down key. An android with an exclamation mark will appear. Now you need to press the power button. A menu will appear where you need to select Wipe data / Factory reset.

And on the tablets of this company, you need to move the screen lock lever to the left position, hold down and hold the power button and the sound control keys. When the tablet starts to vibrate, you need to change the position of the screen lock lever several times until the display shows Erasing Userdata and Erasing Cache. From this moment, the deletion of the settings will begin.

To return to the factory settings, the Asus device must be transferred to the engineering menu by pressing the volume down key and holding the power button for 3 seconds.

After the time has elapsed, the power button can be released, and the volume down key can be held until a special menu appears. There you need to select the item Enter recovery mode, then - Wipe data / Factory reset.

Device firmware

If a hard reset did not help, a complete replacement is required. software. But there is a formality here: the firmware will help only if the “USB debugging” function has been enabled in the device settings. This method is quite risky and at the slightest violation of the instructions can lead to damage to the device.

Here it is worth considering: should I try to restore the device on my own or trust professionals? But if you decide to flash the gadget yourself, you should carefully study all the available information on this issue. Models from different manufacturers have significant differences and features regarding the change of software.

In general, the software replacement process looks like this: a file with firmware is downloaded, installation information is studied, and reviews about this firmware version are read. Next, the file should be unpacked to the root directory of drive C and, if necessary, install the drivers for the gadget. After that, the device must be turned off and using a key combination (usually a combination of the power button and volume up) is switched to firmware mode. After that, you should connect the device via a cable to the computer and follow the further instructions of the program. At the end of the process, it is imperative to perform a hard reset using the engineering menu.

If an android with an exclamation mark appears on the screen, this means that an unsuccessful experiment was carried out with the device software. Perhaps this happened due to the installation of an unlicensed program or after switching from the original firmware to custom.

But there is a formality here: the firmware will help only if the “USB debugging” function has been enabled in the device settings. This method is quite risky and at the slightest violation of the instructions can lead to damage to the device.

What should be done after restoring the device?

The main disadvantage of resetting the settings is the loss of information stored in the gadget: photos, videos, applications, music, contacts, etc. Therefore, it is best to regularly synchronize your smartphone or tablet with Google.

This gives very great opportunities. For example, if you take a browser, then synchronization with it will allow you to access saved passwords, bookmarks and other useful things in any gadgets.

Thus, synchronization with a Google account is necessary for the convenience of using various services and applications. You can also sync contacts to mobile phone with Google contacts.

If synchronization with Google has not been carried out, then it is better to do it immediately after the gadget is restored to working order. First of all, you need to add a Google account. If you already have an account, please enter your email address and password. Email and click OK. After that, it will be proposed to backup and restoration, which will create backup data of this device in Google account. By pressing the "OK" button, you should confirm the synchronization and wait a few minutes.

After the process is completed, you need to click on the email address, where it will be seen that all services have been updated. You will receive a notification that new messages have been received and that photos have been synced, the browser Google Chrome, google drive, calendar and contacts. Synchronization of a tablet or smartphone with Google is best done as often as possible.

Users of devices with the Android operating system are faced with an unpleasant problem: shortcuts on the home screens are duplicated. The problem occurs on any firmware, including latest versions. Removing a shortcut on some devices will remove the app.

Possible Causes of the Problem

Duplicate shortcuts occur for various reasons:

Failure as a result of rebooting the device or resetting the settings to factory settings;
The problem is caused by a third party application (its incorrect setting by developers)
Applications are installed twice, on internal and external memory;
The application incorrectly duplicates information in the cache, which causes the launch icon to split in two;
Unsuccessful device update or firmware update.

Other reasons are possible. Most often, the problem extends to third party applications. Icons of standard software, as a rule, are not duplicated.

How can this be fixed

There are several ways to stop duplication of application icons on the screens of Android smartphones or tablets.

Unchecking Google Play

The GooglePlay service has a function that adds app shortcuts to screens automatically. Disabling this feature will prevent the user from creating shortcuts and duplicates:

In the future, apps downloaded from GooglePlay will stop creating icons.

Cleaning up launchers

Launchers are small applications. Through one of them, you can fix the problem of duplicated icons. In Google Play, you need to download any launcher. To do this, enter the query "Launcher" in the search bar. Once the application is downloaded and installed, you need to:

The final button for deleting settings may be called a little differently. After this procedure, the downed phone settings will be restored, the desktop will be cleared of unnecessary shortcuts.

Clearing the Dalvik cache

The cache stores temporary program files in the section of the same name. internal memory, is used on all operating systems Android. To work with the Dalvik cache, you need Root rights. The files in this section are necessary to speed up the launch of the most frequently used applications on the device.

You can clear the cache of a smartphone or tablet using the following algorithm:

Enter the device settings;
Go to the "Storage" or "Memory" section;
Click on the entry "Cache data";
At the bottom you will be prompted to clear the cache.

The procedure may take up to 2 minutes, depending on the number of files in the cache. Cleaning will help remove residual files, including those that provoked duplication of shortcuts. Also, you can clear the cache using special applications.

Working with firmware

Most of the problems occur for users who have switched to custom firmware Android. Restore factory firmware With complete removal information about the current state of the device can be through recovery menu. This menu called differently on devices of different brands.

After entering Recovery Mode, you must select the line "install zip from sdcard", confirm the selection. Reinstalling the firmware takes up to 10 minutes. It is recommended to charge the device in advance and save important files, they will disappear.
