What to do if the lock screen disappears. How to lock the Windows screen. Adding Apps to Display

A lock screen is a great way to protect your Android smartphone from unauthorized persons and accidental clicks that can cause leakage of personal information or unwanted calls. But sometimes a screen lock is simply not needed. For example, on a tablet computer that is used exclusively at home.

If this is your situation, then this material should help you. Here we will talk about how to disable the screen lock on an Android smartphone with a standard interface or an interface from Samsung.

Disabling the screen lock in the standard Android interface

First, we will show how the screen lock is disabled on Android devices with a standard interface. To do this, you need to go to the Android settings and open the “Security” section there (the “Personal Data” settings block).

Next, you need to go to the “Screen Lock” section, it should be at the very top of the screen. It should be noted that if your device is configured to unlock using a password, PIN code or pattern, then when you enter the “Screen Lock” section you will be asked to unlock the device again. Without this, you won’t be able to go to the “Screen Lock” section and disable the lock.

As a result, you will see a list of all possible ways to lock the screen on your Android device. If you want to completely disable the screen lock, then you need to select the “No” option here.

That's all, you have disabled the screen lock. Now the device will turn on immediately after pressing the Power button and will not distract you with the need to perform additional actions.

Disabling screen lock on Samsung smartphones

If you have a smartphone with a non-standard interface, then your process for disabling the screen lock may be slightly different. For example, we will show you how to disable the screen lock if you have an Android smartphone from Samsung,

So, first of all you need to open the settings. Once the settings are open, you need to go to the “My Device” tab and open the “Lock Screen” settings section.

As a result, the lock screen settings will open in front of you. Now you need to go to the “Screen Lock” section, where you can select a locking method. If you are locked using a password, PIN code or pattern, you will be asked to unlock your device again before entering this section.

Once the list of available blocking methods opens, select the “None” option.

That's it, screen lock is disabled. Now your smartphone will turn on immediately after pressing the Power button and will not distract you with the need to perform additional actions.

It seems that the locked screen is an obstacle to accessing the smartphone. However, as it turns out, a selective patterned lock can be cracked in just 90 seconds, and to bypass fingerprint security you'll need an inexpensive dental composite and some Play-Doh.

There are five ways to lock the screen on Xiaomi. Let's look at the features of each of them in detail.

Password and PIN

The most popular and effective smartphone protection. The user can create a PIN code of at least 4 digits or a password consisting of upper and lower case letters, special characters and numbers. It's not easy to guess unless we apply some of the most common combinations such as qwerty, asdf, 1234 or 1111, dates, names or names.

Despite the high effectiveness of such a password, one smart user discovered a vulnerability that allowed access to a password-protected Android 5.x smartphone.

Just launch the Camera app and then enter a very long string on the emergency call screen. This caused the device to temporarily freeze and then become completely unusable. This vulnerability was fixed when the system was updated, but from time to time new methods appear that help to bypass the password lock (i.e., unlock the phone without knowing the password) or PIN code.

With this method, unlocking your device requires you to place your finger on the screen in a given pattern in a nine-dot box. The pattern should be from 4 to 9 points. This gives about 150 million possible combinations. However, in practice, users only use a fraction of this number, so the method itself is not as secure as it might seem.

According to a survey of mobile security experts, every fourth Xiaomi smartphone is protected by one of the 15 most popular pattern locks. In theory, this means that it could take up to 90 seconds for an attacker to unlock a smartphone.

Iris scanning

The peculiarity of each person’s iris is its unique location and unchanged over the years. This allows the iris, like a fingerprint, to be used as biometric security.

To scan the iris of the eye, a special module and an LED are used to illuminate the face with infrared light. The scanning process is very fast - unlocking the smartphone in this way takes less than a second.

Unfortunately, despite the seemingly high level of security, this method was very quickly hacked. For the hacker going by the moniker Starbug, all that was needed was a properly created photograph of an eye and a contact lens applied to it. The latest Samsung Galaxy S8 equipped with an IRIS scanner was successfully unlocked using this approach.

Therefore, Xiaomi did not use such protection technology in new smartphone models.

Fingerprint

A fingerprint scanner is nothing new in the world of technology, but it has only recently gained popularity in the consumer market. The role is to identify the user following the unique pattern of grooves and ridges on the fingertip. Every person in the world has their own unique pattern.

However, the fingerprint scanner, like any other security, does not provide 100% protection. It is enough to buy an inexpensive dental composite and you can gain access to the user’s palm. In 2014, hackers managed to print the fingerprint of the German defense minister based on a photograph published on the Internet.

Smart Lock

As a curiosity, you can change the method, which protects your smartphone and does not require you to enter a PIN code or draw a pattern every time you want to use it.

Android smartphone users can use the Smart Lock option, which allows them to automatically unlock the device in certain situations. The smartphone remains unlocked:

when the device detects that it is near the body,
when in a certain place,
if within range of a specific Bluetooth device,
when it detects the user’s face or voice command (unlocking a smartphone by voice).

These features work thanks to the accelerometer, Bluetooth, GPS and front camera. Additional protection - automatically turns on the screen lock after 4 hours of inactivity.

How to protect your smartphone?

To protect your smartphone, do not use simple patterns (shape patterns) to lock your screen. Avoid references to names, dates, and common words when using PINs and passwords.

Disable all functions that allow you to give access to your smartphone to a third party. And the best thing is to use double protection and minimize the number of unsuccessful unlocking attempts

What is the safest locking method?

As you can see, none of the above screen lock methods guarantee complete security of our data. To avoid being an easy target, you need to use a complex password and follow the most important rule: security is more important than comfort! Use complex passwords rather than convenient graphic keys.

Screen locking has been around on phones for quite some time. This feature turns on automatically when the device goes into sleep mode and ensures that the user does not accidentally touch the display, make a call, send an SMS or change settings.

In the Android operating system, the standard lock screen is very simple and can quickly become boring over time. If you want to change your screensaver wallpaper, get quick access to programs, and even make your smartphone look like an iPhone, it's time to think about an alternative. A selection of the most elegant, fun and practical screens was compiled by Vesti.High-Tech.

One of the best screensavers on Google Play. Unlocking is done by sliding the slider from left to right to the end. Moreover, if the slider along the way is stopped at one of the “notches” (SMS, calls or Gmail), a preview of the desired application will open. The number of unread SMS, letters (with the sender's name and header) and missed calls will also be shown there. To start the program, the switch must be released.

Instead of Gmail, you can choose any other application installed on your smartphone, but after replacing, the icon on the slider will remain the same. Unfortunately, the utility does not replace the standard blocker, but is shown after it. You cannot add your own sliders, like icons. There is no support for the Russian language.

Some utilities require administrator rights to work correctly. If you no longer need the application, then before you delete it, you need to go to “Settings” → “Security” → “Device Administrators” and uncheck the program.

Delayed Lock(60 rubles) allows defer blocking. After a certain time it will turn on automatically. The program will help if you are tired of entering a PIN code, password or pattern (pattern) every time you turn on your smartphone. There is a free version for testing. Owners of Android 4.0+ must have root rights.

Unlock with Wi-Fi(75 rubles) - determines whether the smartphone is connected to a wireless network and removes the lock (including password protected), when you are at home. Integrated with WidgetLocker. The utility can itself disable Wi-Fi, Bluetooth and auto-sync if the connection to the home network is lost.

By default, any smartphone or tablet, after pressing its power button, prompts you to swipe across the screen. Only after this you will be taken to the desktop. This is done to prevent the device from performing any actions on its own while in your pocket. Google does everything to make the lock screen as convenient as possible. But sometimes people still wonder how to disable screen lock on Android. This can be done very simply.

But first, a little theory. If you disable screen lock completely, it may cause some problems. It’s not without reason that Google increases the functionality of the screen, allowing you to go directly from it to taking photos, making calls, and sometimes some other functions. If you don't like the traditional way of unlocking your device, then why not try a different one?

At the time of writing, the following types of screen locks were standard for Android:

Swipe across the screen- the same traditional unlocking method.
Entering a PIN code- a very old method that is quite secure. The simplest selection of a PIN code does not work here, since after several unsuccessful attempts a timer appears - a new entry will be available only after it has expired.
Graphic key- ideal for those who remember visual information better than a set of numbers.
Fingerprint- the most reliable way to protect the information contained on your smartphone. Outwit fingerprint sensor almost impossible.
Iris- its scanning is implemented in Samsung Galaxy S8 and S8+. In the future, this unlocking method will be implemented in other flagship devices.
Entering your password- the longest unlocking method. A password differs from a PIN code in that it can contain letters and other symbols.

You can find many other lock screens on Google Play. They may use other methods - for example, solving a math problem. But this is more of an indulgence than a real improvement of the existing system.

Removing the lock screen

If you want to remove the lock screen, you will have to dig into the settings. However, there is no need to be afraid. If you follow our instructions, the whole process will only take you a couple of minutes:

Step 1. Go to " Settings».

Step 2. Go to the section " Safety" Some devices skip this step.

Step 3. Select " Screen lock».

Step 4. Here click " No" or " Absent».

This way you can disable the pattern or remove any other types of screen lock. However, do not forget that the system may require you to enter a password or PIN code, if one has been set. This was done for security purposes - what if you now have someone else’s smartphone in your hands? Therefore, it will not be possible to remove the password from the lock screen without entering it.

What to do if the pattern key or password is forgotten?

Everything is much more complicated if you have forgotten your password, PIN code or pattern. In this case, you won’t even get to the settings section. Fortunately, the problem can be resolved on some devices. After several unsuccessful attempts to enter the key, a graphical screen lock may offer to get to the desktop in a different way - by entering data from your Google account.

If Internet access is disabled on your smartphone, you will have to reset settings to factory defaults using Recovery mode. User files from the phone will be deleted, as will all settings. At the same time, the screen lock will be eliminated - it will return to its previous appearance when you need to swipe your finger across the display.
