Has your Android smartphone been locked, and are you having trouble unlocking it now because you have forgotten phone password? Looking for methods to remove the password from your Android phone without doing a factory reset?

If the answer is “YES,” you’ve come to the correct spot.

Many people, including you, have had similar issues and wish to know how to unlock an Android phone without a password.

As a result, we have created some of the greatest guidelines or, you might say, top ways that may assist you in unlocking Android phones today, simply for you and countless other Android users.

Part 1: Unlock Your Locked Screen Without Password By 6 Efficient Ways

1. By your Google account

You can use your Google Account to unlock the Android phone password if, after several tries, you are still unable to do so without doing a factory reset.

You need to log into the Google account that is associated with the Oppo A78 device, then do the following:

  • The unlock pattern may only be used five times before a notification telling you to try again in 30 seconds appears.
  • “Forgot pattern” will show up at the bottom of the screen.

unlock with security question

  • You must enter the Gmail account that is associated with the Oppo A78 device here before selecting “Next.”

answer the security question

  • That’s it; from this point forward, you may enter any new PIN or pattern that you can recall to unlock your smartphone.

2. Google Find My Device

Using your Google account is a superb method for finding the Oppo A78 device when lost or stolen.

In addition, it may be used to lock or ring your smartphone. You may have noticed that there are three options available when using this feature: “Ring,” “Lock,” and “Erase.”

To bypass the Android lock screen, all you need to do is sign into the Oppo A78 device’s associated Google account and then follow these steps:

  • On any Android device or a computer, go to <www.google.com/android/find> and sign in using your Google account. Choose the Android smartphone you wish to unlock after that.
  • After choosing the Oppo A78 device, select one of the three options, “lock,” from the list.
  • There will be a new pop-up window that you can use to change the Oppo A78 device password. Additionally, you can choose to add a phone number or recovery email.
  • Confirm it immediately, then input the password you just established on your locked device.

enter new password using google find my device

Many Samsung customers have this issue, which prevents them from using their devices. Try using the “Find My Mobile” feature on your mobile if you wish to unlock it if you’re a Samsung user. It would be helpful if you had a Samsung or Android model account.

After that, use Find My Device to unlock your Android phone without losing any data by following the instructions below:

unlock samsung without data loss

  • Sign in with your Samsung account at findmymobile.samsung.com.
  • Choose “Lock my screen” from the menu on the left, type a new PIN in the box given, and then click “LOCK.”

Your smartphone will be unlocked, and the password will be changed to the new one after a brief delay.

3. Use ADB (Android Debug Bridge)

Without a factory reset, Android phone passwords may also be unlocked using the Android Debug Bridge (ADB).

  • Here, you must use a USB cable to connect your Oppo A78 to the computer
  • This will activate the developer option on your smartphone if you navigate to Settings > About Phone > and choose the “Build Number” option seven times.
  • After that, activate USB debugging by going to Settings > Developer Options.

  • Launch the command prompt in the ADB installation directory after your device is connected to the system.
  • Press enter after typing “ADB shell rm /data/system/gesture.key” into the command line.

go to system and enter command line

  • Finally, just restart your smartphone and use it as normal.

4. Hard reset (data loss)

Each brand has a unique method for hard resetting a locked Android device. The methods to factory reset locked Android devices from Samsung, LG, HTC, Sony, and Huawei are compiled here.

When your phone is locked, you may access the recovery menu of your phone using its physical keys and choose to hard reset the Oppo A78 device. Here’s how to restore a locked phone to factory settings.

  • Use the buttons to see the recovery menu.
  • Press and hold the Volume Up and Side buttons simultaneously until you see the brand logo on the screen for Android devices without a Power/Bixby/Home button.
  • Press and hold the Volume Up, Bixby, and Power buttons all at once if your smartphone has a Power button. Releasing them before a logo arises is advised.
  • Use the Volume Down key to highlight Wipe data/factory reset when the Android system recovery option displays, then hit the Power/Bixby key to choose it.
  • Allow a few seconds for the factory reset procedure to finish after selecting Yes, or Factory data reset. The phone will reboot once you pick the Reboot system. Now you may configure it as if it were a brand-new gadget.

reboot the system and follow factory reset

5. Unlock from Forgot Pattern (android 4.4 or lower)

This is another choice that might assist you in unlocking your phone without a factory reset or password. You may have observed that when pattern lock was enabled on your device, a security PIN question was also prompted at that time.

Therefore, you have the choice to Backup PIN, which might assist you in unlocking your smartphone, if you are unable to unlock it. To do it, take the following actions:

unlock pattern lock using backup pin

  • Click on Android pattern lock.
  • You’ll see a notification telling you to try again in 30 seconds after failing many times.
  • The “Backup PIN” option will be there; choose it.
  • Put the backup PIN and OK here.
  • At last, you may unlock your cellphone by entering the backup PIN.

6. Boot into safe mode

Here’s how you can boot into safe mode.

  • Hit the power button on your phone.
  • Press and hold the volume down button on your phone as the animation begins. Hold it down until the animation is finished and your phone enters safe mode.
  • “Safe mode” will be shown at the bottom of your screen.
  • Out of safe mode
  • Switch off your phone.
  • Press the Power button on your phone for around 30 seconds, or until the Oppo A78 device restarts.
  • You will see that after entering and booting into the safe mode, the lock option will not be visible.
  • Then you will also see the option to turn off boot.
  • You can get rid of the locked phone by proceeding with that option.

How To Unlock Any Oppo A78 Phone Password Using Emergency Call

Today, smartphones are an extension of people. Securing them with a PIN, passcode, pattern, fingerprint, or face unlock has become the norm. It’s like putting a digital lock on our private world.

But you have to face it: sometimes, people forget the codes they set to protect their phones or can’t unlock them with their injured fingers or faces. Picture this: you’re staring at your phone screen, trying to recall that password, but it’s not coming to you.

That’s where emergency call bypass is a nifty little trick that can be a lifesaver. In this article, you’ll learn how to unlock any phone password using the emergency call technique. The article will also explore other methods for when your memory fails you. So, read through and never go through this trouble again.

Part 1: What Is the Emergency Call Bypass Method?

The Android emergency call bypass method is a lesser-known workaround for those unfortunate moments when you’re locked out of your phone. This method exploits a loophole in the phone’s lock screen, allowing you to access your device even when you’ve forgotten your password, PIN, or pattern. It’s like finding a secret backdoor when the front door is bolted shut.

“How can unlocking Vivo, Oppo, and Samsung phones using emergency calls be effective?” You may ask. Imagine you need to access important information on your phone but can’t remember your lock screen code. Instead of panicking or rushing to a technician, the emergency call bypass can be a quick and handy solution. It’s particularly useful when immediate access to your phone is crucial and you don’t have time to reset your password through official channels.

Limitations of the Emergency Call Bypass Method

However, it’s important to note that this method has its limitations. It primarily works on older Android devices, specifically those running Android 5.0 (Lollipop) and below. As smartphone technology has evolved, manufacturers have patched many loopholes to enhance security. So, this method might not work for you if you have a more recent Android version.

But don’t worry – if you’re locked out of a newer phone, you can try several other methods, which you will explore later in this article. Remember, the emergency call bypass can be a lifesaver in specific scenarios. However, it’s always best to use such methods responsibly and ethically. And, of course, you should always note your passwords.

Part 2: How To Perform Emergency Call Bypass To Unlock Screen

Unlocking your Android phone without a password using the Emergency Call Bypass method can be tricky, but it’s doable, especially on devices running Android OS 5.0 (Lollipop) and below. Here’s a step-by-step guide on how to unlock any phone password using the emergency call feature:

  • Step 1: Start by tapping the Emergency Call button on your lock screen. This will bring up the emergency dialer screen.

  • Step 2: Type a series of special symbols on the dialer screen, such as asterisks (*). Do this several times in a row.
  • Step 3: Double-tap the string of symbols to highlight them, then copy the string. Now, tap on the screen to paste the copied string. Repeat this process 10 to 11 times until you can no longer highlight the series.
  • Step 4: Go back to the lock screen. Open the Camera app by tapping the camera icon or sliding left. Simultaneously, pull down the Notification Panel from the top.
  • Step 5: In the Notification Panel, tap the gear icon to try and access your device’s settings.
  • Step 6: When prompted for a password, long-press and paste the copied string into the password field. Repeat this several times until the option to paste is no longer available.
  • Step 7: Keep pasting the string until the interface crashes. The lock screen should disappear, and the camera interface will expand. After some time, the camera app should also crash, and your device will unlock, displaying the home screen.

This method, while unconventional, has been known to work on various Android 5 devices, including Samsung models. However, using this technique responsibly and only on devices you own or have permission to access is important. Remember, this method exploits a security flaw and should be used as a last resort.

Part 3: Other Ways To Unlock Your Screen
