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 Vivo V29 Pro 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.

  • You must enter the Gmail account that is associated with the Vivo V29 Pro 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 Vivo V29 Pro 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 Vivo V29 Pro 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 Vivo V29 Pro 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 Vivo V29 Pro 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.

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:

  • 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.”

  • Here, you must use a USB cable to connect your Vivo V29 Pro to the computer

  • Press enter after typing “ADB shell rm /data/system/gesture.key” into the 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 Vivo V29 Pro 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.

  • 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 Vivo V29 Pro 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.

Forgot Pattern Lock? Here’s How You Can Unlock Vivo V29 Pro Pattern Lock Screen

Forgetting the pattern lock of a device and getting locked out of it is probably one of the most frustrating scenarios faced by Android users. Nevertheless, unlike popular operating systems, Android provides a seamless way to past the forgot pattern lock feature.

You can either try Google’s native solution or a third-party tool in case you have forgotten the pattern lock on your device and reset it. In no time, you will be able to access your device (or even someone else’s phone by following these techniques).

Part 1: How to bypass forgot pattern lock using the ‘Forgot Pattern’ feature?

One of the easiest and fastest ways to fix the forgot pattern lock issue on a device is by using its inbuilt “Forgot Pattern” feature. If you are using an Android 4.4 or earlier version, then you can simply access this feature. Since users can hack an Android device just by knowing the Google credentials of the connected device, the solution was later discontinued (as it was considered a security vulnerability). Nevertheless, if your device hasn’t been updated and you are using an Android 4.4 or previous version, then you can bypass the forgot pattern lock by following these steps:

Step 1. Firstly, provide the wrong pattern to your device. It will let you know that you applied the incorrect pattern.
