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

This action is carried out in the device’s engineering menu 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 from different manufacturers have different key combinations. 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 combinations of buttons to open the menu are suitable:

1. The Volume Down key (or Volume Up key) is pressed and held together with the Power button.
2. Both sound control keys are pressed and held, and then the power key is pressed.
3. 3 buttons are held simultaneously: main screen, volume up and power.
4. The Home key is pressed together with the sound control key down, then the Power key is pressed. You must wait until the manufacturer's 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.
5. Press and hold the power button for 2 seconds, then hold down the sound control keys and the power button and hold until a special menu appears.

After this, the gadget will either restart and return to 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 carried out using the sound control keys, and the selection button is the power key or the Home button. You must select “Wipe data/Factory reset”.

Several lines and a question will appear on the display (“Delete all data from your device?”). You must agree, after which the device’s memory will be cleared.

Reset on different devices

On smartphones and tablets manufactured by Samsung, the engineering menu is entered by pressing 3 buttons simultaneously: the gadget's main screen 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 Android with a red exclamation mark appears on the display, can be brought back to life by pressing and holding the power and sound control buttons. When Warning appears on the display, you can release everything and press the volume up key. On some models, hold down the volume button and press the power key until an android robot appears on the screen. After it appears, you can release the buttons and press the volume down key again. A menu will appear in which you need to select “Restore original settings”.

On Acer smartphones, settings are reset by pressing and holding the volume up key and the power button. A menu will appear on the screen where you need to select Recovery Mode 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, press and hold the power button and sound control keys. When the tablet starts to vibrate, you need to change the position of the screen lock lever several times until the words Erasing Userdata and Erasing Cache appear on the display. From this moment, the removal of settings will begin.

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

After the time has passed, you can release the power button and hold the volume down key until a special menu appears. There you need to select Enter recovery mode, then Wipe data/Factory reset.

Device firmware

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

Here it’s worth thinking about: should you try to restore the device yourself or trust the 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 software changes.

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

If you're having problems connecting to your Wi-Fi network (such as authentication or connection stability), try the solutions below. You can tell if there's a problem by seeing an exclamation mark next to the Wi-Fi icon on your Pixel or Nexus device's screen.

After each step, try connecting to the network again and opening any website on the device.

Step 1: Check your settings and reboot your device.

Step 2: Determine the source of the problem.

• Device
  Try connecting to the Wi-Fi network from another device, such as a laptop or a friend's phone. If the connection is successful, the problem is likely with your device.
• Net
  Try connecting your device to a different Wi-Fi network, such as at a café or at a friend's house. If the connection is successful, the problem is most likely on your network.
• Internet
  Does your device connect to the network but can't access the Internet? The problem is probably related to your Internet connection.

Step 3: Fix the problem.

Troubleshooting device problems

Troubleshoot network or internet connection problems

Restart your Wi-Fi router or modem

If you have access to your router or modem, turn it off and on again. Here's how to do it:

1. Unplug your router or modem's power cord from the outlet for 15 seconds.
2. Reconnect the power cord to the outlet.
3. Make sure all cords and cables are securely fastened on both sides.
4. Wait a few minutes until the lights on your modem or router start working as normal.

If the lights are not blinking as instructed, the problem may be with your modem, router, or Internet connection.

In this case, contact your network administrator or Internet service provider. The problem may have occurred due to a power outage or internet connection reset.

Sign in to connect to a public network

Typically, to use a public Wi-Fi network (for example, in a cafe or airport), you must sign in on the authentication page. Otherwise the connection will not be established.

If this page appears when you connect to the network, sign in or accept the terms of use.

If the authentication page does not open, follow these steps:

• Check to see if a login notification appears.
• Try opening a new web page in a new window.

If this doesn't help, try connecting to the network again. Here's how to do it.

What is this article about? We look at the cellular network signal strength indicator. There is an exclamation mark on it. What does it mean? The Android mobile operating system for smartphones and tablet devices is designed to provide easy access to a variety of online content, including email, social networks, blogs and financial websites. To make the best use of the wide range of Internet applications available on Android, connect your device to the Internet via wireless Internet networks. This will allow you to browse the web at much faster speeds while reducing your mobile data usage.

Why is this sign placed at the smartphone network level?

Exclamation mark at the cellular network level

This article is not about the exclamation point on the Wi-Fi icon. This article is not about the exclamation mark on the Wi-Fi icon on your computer. This is exactly about the exclamation mark on the cellular signal strength.

On Android 5 and higher, this feature appeared. It lies in the fact that there is no Internet on the smartphone. No mobile internet, no GPS, no Wi-Fi.

It's simple. If you connect any mobile Internet or GPS or any Wi-Fi, then this exclamation mark icon disappears.

Turned on Wi-Fi, the exclamation mark disappeared

Turned off Wi-Fi, exclamation mark appears

There were questions, but there were no answers on Google. Well now you already know what it is.

Internet on a smartphone

Smartphones, such as iPhones or Android phones, are basically small handheld computers with mobile connectivity, GPS and a camera. Like any other modern computer, they are a means of accessing the Internet. For many, this is their main function.

Most smartphones use two different technologies to access the Internet: cellular and Wi-Fi. The advantage of the cellular network is that it works almost everywhere. You can access the Internet from almost anywhere you have cellular service.

However, with most phones and in most places you get third generation (3G) and sometimes second generation (2G) service, which is very slow. You can also get 4G, but most phones that people already use do not support this signal. Moreover, 4G is widespread in a small number of cities.

Of course, Wi-Fi can be much faster, depending on the network. But it is not available everywhere. Wi-Fi at your home, in a cafe, in the library and in the office. Wi-Fi greatly limits you in the area. You need to know the password for the Wi-Fi network. Another problem: Wi-Fi drains your phone's battery faster than 3G.

Is your Android smartphone malfunctioning? Bring it to us!

If the phone screen shows an exclamation mark and the green android (operating system symbol) is down, this means that the operating system of your device is down.

Android lies - Exclamation mark on the phone!

The system refuses to work because:

• Android is damaged by a virus;
• an application incompatible with the OS was installed;
• the phone was flashed incorrectly (ineptly) or with an incorrect OS version.

How to upgrade Android?

1. Even a non-commercial antivirus quite reliably protects the system from malware. Ignoring the risks of viral damage costs yourself more.

2. If there is incompatibility with the application, the problem can be resolved by pressing the “reset” button. After a reboot, the device will most likely work.

3. It is guaranteed that the exclamation mark on the phone will disappear, and the Android will greet the user again after flashing the firmware - installing Android OS on the formatted disk of the gadget. But you can try to raise the system without firmware, by resetting it to factory settings. For this:

• We enter the settings menu using a combination of touch keys: home, power and the volume down key, pressing them together (provided that the home key is available), wait until the service menu appears;
• In the menu, use the touch volume control to select yes, the device should reboot automatically;
• if it does not reboot, select the rebootsystemnow menu item.

Important!

When resetting to factory settings, all user data (photos, recordings, etc.) will be lost. Cheap Chinese smartphones are dropping support for the Cyrillic and Latin alphabet. In order not to have problems with decoding hieroglyphs, and especially not to damage the “filling” with unqualified firmware, it is better to immediately contact a specialist at the nearest service center.

The green android robot no longer greets you when you turn it on, but lies accompanied by an exclamation mark.
So, if you see this picture - the android is lying with an exclamation mark, then you can be congratulated, you have made your first unsuccessful experiment in interfering with the software of your device. What is it, and most importantly, what to do with it and how to restore the viability of the device? The search for answers to these questions must begin, first of all, by finding out the reason that led to this condition.
If you installed an incorrect program for Android, then after rebooting it will definitely please you with an image with an exclamation mark. There is only one way out - to do a hardware reset by selecting Wipe data/factory reset in the engineering menu.

Entering the engineering menu if your Android is different on different Android smartphones, but the combination of the home, power and volume down keys is recognized as standard. On devices with a touch home button, a combination of the power and volume down keys is usually used. The key combination suitable for your device must be pressed with your fingers and held until the service menu appears on the screen.

After the inscriptions appear, you must select the appropriate item by moving up and down using the volume rockers. After selecting this item, several lines will appear on the device screen asking whether you agree to delete all data from your device. After selecting the yes line, the device memory will be completely cleared. The next step, if the device does not reboot automatically, select rebootsystemnow, which means rebooting the system. If after these operations your device has restored its functionality, then we can congratulate you. The only disadvantage of this method is the loss of all information - including contacts, SMS, photos and downloaded applications.

However, if you regularly synchronize your phone with Google and remember your account login and password, then your losses will be insignificant.
If the above method does not help, then you need to completely replace the software. There are two ways - the first is flashing the device using a USB cable and a computer, but it will only help you if the “usb debugging” function has been enabled in the device settings. The second way is to update the software using a flash card through the engineering menu. Both methods are very risky and the slightest violation of the instructions will lead to the complete destruction of the device. At this stage, you should think about whether to try to restore the device yourself or trust the professionals.

If you nevertheless decide to flash an Android with an exclamation mark yourself, then you should carefully study all the information provided on the Internet on this issue. Certain types of Android devices have significant differences and features regarding software changes. If we briefly and generally describe this process, it looks like this: you find the firmware file on the Internet, download it, simultaneously studying reviews about this version and installation information. After this, you decide on the method of performing the Android recovery procedure with an exclamation mark.

If you chose the method using a USB cable, then unpack the firmware files into the root directory of drive C on the computer, install drivers for your smartphone if necessary, turn off the phone, use the key combination (usually the combination power+volume up) to enter the phone into firmware mode, connect via a USB cable to the device and follow the further instructions of the program. At the end of the process, be sure to hard reset your device to default settings using the recovery menu.

If you decide to resort to the second method and restore the software using the device itself and a flash card, then the steps are as follows - upload the firmware file to the root directory, insert the flash card into the phone and launch it in recovery mode. After the engineering menu appears, select the recovery option using SD and wait. After finishing, you also need to reset your Android device.
