3. Methods to Remove Screen Lock on OPPO A72
There are several methods to remove the screen lock on the OPPO A72, each with its own set of steps, requirements, and implications. Below, we’ll go through the most commonly used methods:
3.1. Using Google Find My Device
Google’s Find My Device is a convenient tool that allows you to remotely unlock your device. This method is particularly useful if you’ve forgotten your screen lock credentials but still have access to your Google account.
Steps:
- Access Find My Device: On a computer or another phone, go to the Find My Device website (https://www.google.com/android/find) and log in with your Google account credentials that are linked to the locked OPPO A72.
- Select Your Device: Once logged in, select the OPPO A72 from the list of devices associated with your account.
- Choose ‘Erase Device’: Click on the ‘Erase Device’ option. This will wipe all data on the phone, including the screen lock. Note that this will remove all data from the phone, so it should be used as a last resort if you have no other way to unlock the device.
- Set Up the Device Again: After the device is erased, it will restart, and you can set it up again without a screen lock.
Pros:
- Easy and straightforward process.
- Can be done remotely.
- Effective for forgotten passwords/PINs.
Cons:
- All data on the device will be lost.
- Requires the device to be connected to the internet and linked to a Google account.
3.2. Using OPPO’s Find My Phone Service
Similar to Google’s service, OPPO offers its own Find My Phone service, which can also be used to unlock the device remotely.
Steps:
- Log into OPPO Cloud: Visit the OPPO Cloud website (https://cloud.oppo.com) and log in with your OPPO ID that is linked to the locked device.
- Select ‘Find My Phone’: Navigate to the ‘Find My Phone’ section and select the OPPO A72.

- Remote access and unlocking.
Cons:
- Requires an OPPO ID and internet connection.
- All data will be erased.
3.3. Using Recovery Mode (Factory Reset)
If remote services aren’t an option, performing a factory reset through Recovery Mode is another method to remove the screen lock. This method is effective but comes with the significant downside of erasing all data on the device.
Steps:
- Power Off the Device: Hold the power button and select ‘Power Off’ to turn off the OPPO A72.
- Enter Recovery Mode: Press and hold the Volume Down button and the Power button simultaneously until the OPPO logo appears. Release the buttons when you see the OPPO Recovery Mode menu.
- Navigate to Wipe Data: Use the volume buttons to navigate to ‘Wipe Data’ and press the Power button to select it.
- Confirm the Reset: Confirm your choice by selecting ‘Wipe Data (Keep SMS, Contacts, and Photos)’ or ‘Wipe Data’ (which erases everything). This will remove the screen lock along with all other data.
- Reboot the Device: After the wipe is complete, select ‘Reboot’ to restart the device. The screen lock will be removed, and the device will start fresh.
Pros:
- Doesn’t require internet access or linked accounts.
- Effective for severe cases of lockout.
Cons:
- All data on the device will be erased.
- Requires manual reconfiguration of the device after reset.
3.4. Using Third-Party Software
Several third-party software tools are available that claim to unlock Android devices without data loss. Tools like Dr.Fone – Screen Unlock (Android), iMyFone LockWiper (Android), and Tenorshare 4uKey for Android are popular options.
Steps:
- Download and Install the Software: Download the software on your computer and install it.

- User-friendly interfaces.
Cons:
- Success rates vary depending on the device and software version.
- Some tools require payment.
- Security risks associated with using third-party software.
4. Precautions and Best Practices
Removing the screen lock from your OPPO A72 should be done with care. Here are some precautions and best practices to follow:
4.1. Backup Data Regularly
The most significant risk of removing a screen lock, especially when using methods that involve a factory reset, is data loss. Regularly backing up your data can save you from losing important information. Use cloud services like Google Drive, OPPO Cloud, or physical backups to ensure your data is safe.
4.2. Understand the Implications
Before removing the screen lock, especially if using remote services like Google Find My Device or OPPO’s Find My Phone, understand that these methods will erase all data on the device. If possible, try to remember your screen lock credentials before resorting to these measures.
4.3. Use Trusted Methods and Tools
While third-party tools can be tempting due to their promise of unlocking without data loss, it’s crucial to use trusted and reputable software. Research the tool, read reviews, and ensure it’s from a reliable source to avoid potential security risks.
4.4. Keep Software Updated
Ensuring your OPPO A72 is running the latest software updates can prevent some issues that might lead to needing to remove the screen lock in the first place. Regular updates can fix bugs and improve security, reducing the likelihood of lockouts due to software malfunctions.
5. Risks Involved in Removing Screen Lock
While the process of removing a screen lock might seem straightforward, several risks are involved, especially when dealing with third-party software or methods that erase data.
5.1. Data Loss
As mentioned earlier, the most significant risk is data loss. Methods like factory resets and remote device erasure will wipe everything from your device, which can be catastrophic if important data is not backed up.
5.2. Security Risks
Using third-party software carries inherent risks, including the potential for malware or unauthorized access to your data. Always download software from reputable sources and consider the security implications.
5.3. Warranty and Support
Attempting to remove the screen lock using unofficial methods could potentially void your warranty. If you’re unsure, it’s always best to contact OPPO support or visit an authorized service center before attempting to unlock your device.
5.4. Permanent Damage
In rare cases, improper handling of the device during the unlocking process can lead to permanent damage, such as bricking the phone. This is more likely if you’re using methods that involve entering recovery or download mode without proper knowledge.
