TOP 9 best apps to change screen lock on Android

— Advertisement —

The Android lock screen is constantly evolving. There are different ways of slide unlocking, and manufacturers are always contributing to its development. It turns out that there are many lock screen apps on the Play Store that have even more features. Now I recommend people just use the fingerprint scanner to bypass the lock screen altogether. However, it's okay if you don't want to do this. Below are the best screen lock apps for Android.

It's important to note that lock screen apps are not as popular as they used to be. As I wrote above, I recommend using the built-in screen lock or not locking the screen at all. In most cases, you click on the fingerprint scanner to turn on the smartphone. Additionally, third-party lock screen apps are less secure than the built-in ones.

AcDisplay

AcDisplay

Developer: Artem Chepurnoy

Price: Free

AcDisplay is one of the most popular lock screen apps. It enamel the screen locks of smartphones such as Moto X, Galaxy S8 and others. Users can view notifications without unlocking the display. It also has a few settings. For example, you can set it to only work during certain hours to save battery power. More and more smartphones with something similar are appearing on sale. Thus, I would recommend AcDisplay only to those smartphones that do not already have such a feature. The app was last updated in 2015. I'm not sure the developer will continue to support it. At least it's free.

How to enable smart unlock

• Set a smartphone lock password;
• Then go to “Settings” - “Security and Privacy” - “Smart Unlock”;

Android has smart unlocking. But she's not that reliable

• Select a condition under which your smartphone will not be blocked (in my case, this is a connection to an accessory, the role of which can be played by headphones, a fitness bracelet or a watch);
• Establish a connection with your Bluetooth accessory or, if you choose another option, outline a safe zone or select a trusted Wi-Fi network and save the settings.

Always On AMOLED - BETA

Always On AMOLED

Developer: Tomer Rosenfeld

Price: Free

Always On AMOLED is not a lock screen, but an imitation of it. It mimics the Always On Display feature of most smartphones. The application can show the time, notifications and other similar information. I only recommend it on phones with an OLED display, including Samsung AMOLED. It doesn't look as cool on regular LCD screens. I also only recommend it for smartphones that don't have this feature. The built-in versions almost always work better than third-party apps.

What is a display lock on Android and what is it used for?

Locking the touchscreen on a smartphone limits access to the device by unauthorized persons. This function has several features, each of which deserves special attention:

• preventing accidental taps on the screen while carrying the phone in your pocket. At the same time, a person will protect himself from numerous clicks on the display, which can cause the device to break down;
• inability to save information when resetting settings. If a smartphone falls into the hands of criminals, they will be able to unlock it only by completely formatting the data;
• prevents unauthorized access by close friends or relatives.

Note! The screen lock feature is also useful for people who have small children.

Floatify Lockscreen

Floatify Lockscreen

Developer: Jawomo

Price: Free

Floatify is a popular, modern lock screen replacement app. Actually looks like a standard lock screen. This is a simple background with time. But, you can add information such as weather, notifications and so on. You can also customize the icons at the bottom of the lock screen. It also has other modern features such as turning on the display when you pick up the phone, themes and chat features similar to Facebook Messenger. This is a good replacement for the standard lock screen. But the app hasn't been updated since late 2021, so I'm not sure if it will continue to be updated.

Reset picture password

Sometimes it happens that the user forgets the key due to his own inattention or because of age. Luckily, there are methods to reset this type of lock.

Method 1: Forgot Password Option

In Android versions up to and including 4.4, when entering an incorrect pattern 5 times in a row, the device was temporarily blocked, but an additional reset option appeared, also known as “Forgot my password.” If the target device is running exactly such an old version of the “green robot”, using this function is the optimal solution.

1. Unlock the screen of your smartphone or tablet and enter the wrong pattern about 5 times.
2. The device will inform you that the unlocking option is temporarily unavailable, and the message “Forgot your password” will appear in the lower right corner (otherwise it may be called “Forgot your pattern” or “Forgot your pattern”). If there is none, wait and try entering the wrong pattern a few more times.
3. Tap on the inscription, then enter the details of the Google account to which the device is linked - an unlock code will be sent to it.
4. After receiving the code in your mailbox, go into it from your computer, write down or remember the combination, and then enter it on the target device.

This method is the simplest, but Google considered it unsafe and removed it from subsequent releases of its OS after KitKat. However, some vendors still install it in their products, so this option has not lost its relevance yet.

Method 2: ADB

The Android Debug Bridge tool is a powerful device management tool that will help in solving the problem in question. All that is needed is active USB debugging on the device and the ADB package present on the computer, which can be downloaded from the link below.

1. After downloading, unzip the archive with the program to the root directory of drive C, then run Command Prompt as an administrator - the latter in Windows 10 can be done using Search.

2. Next, enter the commands sequentially:
   cd C:/ADB

   adb shell

3. Now write the following statements one at a time, pressing Enter after each:
   cd /data/data/com.android.providers.settings/databases

   sqlite3 settings.db

   update system set value=0 where name='lock_pattern_autolock'

   update system set value=0 where name='lockscreen.lockedoutpermanently'

   exit

4. Reboot the device, and after the system boots, try entering any pattern - in most cases the device should be unlocked. If it doesn't work, repeat steps 2-3, then additionally enter the following:
   adb shell rm /data/system/gesture.key

   adb shell rm /data/data/com.android.providers.settings/databases/settings.db

   Restart your smartphone or tablet and check the result.

This method is quite labor-intensive and is not suitable for all smartphones or tablets: manufacturers can cut out the corresponding feature in their firmware versions or change the location of the final files.

Method 3: Factory reset

A radical method that is guaranteed to remove a graphic password is to completely reset the device. Of course, this will delete all user data, except for those saved on the memory card, so we recommend using this option only as a last resort, when it is only important to restore the functionality of the device.

Hi Locker - lock screen

Hi Locker - lock screen

Developer: The Lockdown Team

Price: Free

Hi Locker is a pretty typical lock screen replacement app. It can show the weather, notifications, calendar events, etc. Can also greet you with funny greetings and congratulations. There is fingerprint support if you have a scanner. You can also enable automatic wallpaper changing from Flickr. You can turn off notifications from certain apps to prevent people from seeing them. It's not as feature-rich as most of its competitors, but it's great for those who don't need a lot of features.

Lock your phone using Android Device Manager

Enabling Android Device Manager is a smart move.

If your phone is lost or stolen, you can track it, make calls, block it, or erase all data.

You'll need to go into your Google settings (either in Settings or in the separate Google Settings app, depending on your model.)

On Google, go to Security and enable “remotely locate this device” and “allow remote lock and wipe.”

Keep in mind that if you want to find it, you'll have to turn on location services while the phone is still in your hands.

If you lock your phone remotely and don't have a PIN, password, or pattern, your lock screen will be replaced with the password you set from Device Manager.

You can also add a message and a button to call the specified phone number.

KLCK Custom Lock Screen Maker

Price: Free

KLCK are the developers of the popular KWGT Kustom Widgets and KLWP Live Wallpaper applications. Essentially, this application allows you to create your own lock screen. It is based on a simple editor with many functions. You can add notifications, various features, custom graphics, backgrounds, and more. You can also add data from Google Fit, weather, real-time maps, music player controls, and even an RSS feed. The application is in beta version. Therefore, there are errors in the work. But if you need a custom lock screen, this is the one I recommend.

Ways to lock the screen

• There is no blocking. There is no protection at all, and the screen turns on by pressing Power. The desktop starts immediately.
• Simple swipe. Relevant for protection against accidental starts. The user unlocks by moving his finger across the screen.
• Graphic key. The device is unlocked by drawing a pattern by selecting special points. If the user makes an unsuccessful unlock attempt, a pause is introduced before the next attempt, which guarantees the security of the device.
• PIN code. The lock is unlocked after entering several numbers. If several incorrect entries are made, a pause is triggered, which guarantees a higher level of security.
• Password. This option is the safest, but also very time-consuming method. The user must specify a combination of previously selected characters.
• Fingerprint. An innovative method of protection. Currently provides the highest level of security.
• Face recognition. Points on the user's face are scanned.
• Iris scanner. The highest level of protection is provided, because Everyone's retina is different.

To increase the level of security, the user can use third-party software, which requires answering questions and riddles to log into the system. In this area, the possibilities of Android are limitless.

Besides drawing, you can add text to the canvas or insert stickers from available packs. It is also possible to purchase additional stickers.
