In 2024, How To Fix OEM Unlock Missing on Samsung Galaxy Z Flip 5?
How To Fix OEM Unlock Missing on Samsung Galaxy Z Flip 5?
Original Equipment Manufacturer (OEM) Unlock is a function on Android devices. It allows you to unlock your phone bootloader. A bootloader or bootstrap loader gathers the operating system files, loads them into memory, and hands over control, essentially starting your device. Unlocking the bootloader assists you in installing custom ROMs, flashing custom kernels, and rooting your phone.
However, this freedom comes with some trade-offs. Most manufacturers will void your warranty if you unlock the bootloader, and it can also make your phone face higher risks of malware and other security threats. Additionally, it can be difficult to relock the bootloader once you unlock it.
If you encounter the OEM unlock missing on your Android phone despite wanting to unlock your bootloader, this article can help. You will learn the step-by-step guide for the different methods to fix the missing OEM unlock option. Before diving into solutions, let’s explore why this option might be unavailable in the first place.
Part 1: Why Is OEM Unlock Missing on Your Device?
Finding that OEM Unlock is missing on your Android phones can be frustrating, particularly if you plan to modify your software or install a custom ROM. But don’t worry. There are several possible explanations for this. Let’s explore some of the most common reasons:
Manufacturer Restrictions
The Missing OEM Unlock option can often be due to restrictions imposed by your device’s manufacturers. They may intentionally remove this option to safeguard device security and compatibility. It is common with carrier-locked devices. As a result, the OEM Unlock option may not show.
Bootloader Already Unlocked
In some cases, the Android OEM Unlock Missing issue arises when the bootloader has already been unlocked. Relocking the bootloader might make the option reappear. But exercise caution as this process can erase device data.
Developer Options Not Enabled
It might seem obvious, but sometimes the simplest things get overlooked. The OEM Unlock option can only be accessed from within Developer Options. If this menu isn’t enabled, you won’t see it.
Carrier-Locked Devices
The OEM Unlock Missing issue can also occur if your device is carrier-locked. Carriers often impose restrictions to prevent users from switching networks, and bootloader unlocking is one way to do that. Unfortunately, the missing OEM Unlock option is usually intentional, and unlocking your device can be more complicated.
Security Features
Enhanced security features, like Samsung’s KNOX, can sometimes conceal the OEM Unlock option. Temporarily turning off these features might show the option, but it’s crucial to be aware of the potential security implications of doing so.
Corrupted Bootloader
A corrupted bootloader can also lead to the Android OEM Unlock missing problem. The bootloader plays a role in the boot process, and if it’s damaged, it might not display the necessary options. This can be caused by software glitches, failed flashing attempts, or even hardware issues. In this scenario, you might need to consult your device’s manufacturer or a technical specialist to help repair or re-flash the bootloader.
Connectivity Issues
A poor connection between your device and computer can also prevent the OEM Unlocking from showing up. Check your cables and try using different USB ports to ensure a stable connection.
Part 2: How To Enable Missing OEM Unlock Without a Password?
Unlocking your phone’s bootloader (OEM Unlock) varies across models and brands. Some need a passcode or PIN after rebooting the phone, while others don’t. Even if your phone doesn’t require a separate password, your existing screen lock (password, PIN, pattern) will usually be needed to enable the missing OEM unlock option.

Now that you’ve regained access to your device thanks to Dr.Fone - Screen Unlock, you can move forward with enabling the OEM unlock missing option. Next up, we’ll guide you through the steps in several ways. Let’s start with the Developer options.
Part 3: How To Enable OEM Unlock Missing From the Developer Options?
Developer Options, a hidden menu in Android, offers advanced features like app debugging and custom ROM installation. But if the Android OEM unlock option is missing, you can’t unlock your device’s bootloader. Below is a step-by-step guide for you so the OEM unlock missing option will show in the Developer Options. Remember, this process may erase your device data, so a complete backup is essential before proceeding.
- Step 1: Open the Settings app on your Android phone.
- Step 2: Navigate to About Phone at the bottom of the list, then tap Software information.
- Step 3: Tap on the Build number repeatedly (7 times) until you see a message saying, “You are now a developer!“ or similar.
- Step 4: Go back to Settings > System and find the Developer options menu.
- Step 5: Scroll down and tap the toggle switch next to Enable OEM Unlock to turn it on.
- Step 6: A warning message explaining the risks of turning on the OEM unlock will appear. Read it carefully and tap Enable if you want to proceed.
- Step 7: Enter your PIN or password to confirm the unlock when prompted
- Step 8: Your device will reboot, and OEM Unlocking will be enabled.
Part 4: How To Fix OEM Unlock Missing by Adjusting Date and Time?
Some manufacturers intentionally delay the availability of the OEM unlock after a software update for security reasons. Changing the date to a past date before the update rolled out can trick the system into displaying the option, as it thinks the update hasn’t happened yet. It is a temporary fix, and the option will likely disappear again later when the Samsung Galaxy Z Flip 5 device automatically syncs the correct date.
If you intend to try this method, follow these steps to enable OEM unlock missing or greyed out after an Android update:
- Step 1: Open the Settings app.
- Step 2: Go to System or General management, depending on your Android version.
- Step 3: Tap on Date and Time.
- Step 4: Turn off Automatic date and time.
- Step 5: Tap on Set date and choose the desired older date from the calendar.
- Step 6: Tap on Set time and choose the desired time from the clock.
- Step 7: Tap on Done to save the changes.
- Step 8: Go back to the Developers options and turn off the Auto update system option.
- Step 9: Go to Settings > Software update, then turn off Auto download over Wi-Fi.
This method should enable the OEM unlock missing issue. Otherwise, proceed to the next section for another solution.
Part 5: How To Fix OEM Unlock Missing by Removing SIM Card?
Certain carriers restrict bootloader unlocking on their devices to ensure compatibility and prevent unauthorized modifications. For these phones, unlocking the SIM card becomes crucial before you can toggle the OEM unlock option. Here are the steps to fix the OEM Unlock missing or greyed out using SIM card removal:
- Step 1: Use the SIM ejector tool (often included with your phone) or a small pin to push the tray out.
- Step 2: Go to Settings > General Management > Reset, then select Factory data reset. Enter your PIN or password if needed.
- Step 3: Review the warning and tap Reset to confirm.
- Step 4: Once the reset is complete, your phone will restart. Connect to Wi-Fi when prompted.
- Step 5: Skip any prompts to log in to your Google or email account. Then, repeat the process to open the Developer Options in the previous sections.
Having the OEM Unlock missing or greyed out can leave Android users feeling locked out of customization possibilities. Fortunately, this article has outlined helpful solutions like enabling the Android OEM Unlock missing option via the Developer Options. You can also try other methods above, like adjusting date and time settings or even a sim card removal trick. For those facing forgotten lock screens, we’ve offered guidance on bypassing them using the Dr.Fone - Screen Unlock tool to access the necessary phone settings.
While these methods provide a solid foundation, it’s always wise to research steps specific to your phone model. And never forget – caution is key. If things get technical, don’t hesitate to seek help from online communities or professional repair services.

Unlocking the Power of Smart Lock: A Beginner’s Guide for Samsung Galaxy Z Flip 5 Users
Google constantly comes up with features to simplify the way users interact and complete tasks on the Android platform. One of the most important features that techies loved to debate about was the Smart Lock Android, a secure password manager functioning in sync with a Google account on the Android phone.
Part 1: What is Android Smart Lock?
Android Lollipop added a feature called Smart Lock, and the feature was devised as a smart tool to prevent the Android phone from locking once it was initially unlocked. In other words, the feature overrides an Android phone’s Lock Screen feature, thereby saving users the need to enter passwords every time the Samsung Galaxy Z Flip 5 device locks.
If you’re at home, it’s likely your android phone is locked out if you haven’t accessed at for some time. Smart Locks solves the problem in many ways. It allows you to allocate trusted places. Once you within range of the trusted places, your phone won’t lock. Trusted devices come next. Smart Lock is assigned to Bluetooth and Android NFC unlock devices.
Finally, trusted face unlocking is the ultimate face recognition system that unlocks your Android device as soon as you look at it across the front-facing camera. A face unlock first introduced with Android Jelly Bean and has been significantly improved in later versions.
Turning On Smart Lock
The feature is enabled by first accessing settings. For example, in a Samsung Galaxy S6:
Tap on Settings, which is the gear symbol.
- • Click on Personal and tap on Security.
- • Go to Advanced and tap on Trust agents and make sure Smart Lock is turned on.
- • Under Screen Security tap Smart Lock.
- • Here, you need to enter your Screen Lock. If you haven’t done so, set up a password and PIN by following the on-screen prompts. The screen Lock is needed every time you have to change the Smart Lock settings.
Within Smart Lock, there are three options for setting the system. You can set up trusted devices, trusted face, and trusted places individually, combining two or all three at the same time. You can choose just one trusted face, but you have the option to set up as many trusted devices and trusted places as needed.
Part 2: Turn On Smart Lock For Android with Trusted Devices
You can decide on a trusted device to be paired with Smart Lock Android.
For example, you can set up a Smart Lock for Bluetooth in your Android Bluetooth settings. It can also be done for Android NFC unlock devices. Examples include the Bluetooth system in your car, NFC unlocks, android sticker on the car’s phone dock, or Bluetooth in your watch.
- • Go to Settings.
- • Tap on Security and then Smart Lock.
- • Existing paired options are listed under Trusted Devices.
- • Initially, trusted devices will show None.
Tap on Add Trusted Devices.
The next screen is the Choose Device Type.
Since you have already paired Bluetooth, it will ask you to choose the Samsung Galaxy Z Flip 5 device from the list.
- • As an example, let’s take the case of LG HBS800. It may show Not connected until you add it.
- • It will show up under Trusted devices in the Smart Lock menu.
- • When you turn the added device on, Smart Lock now unlocks the Android mobile.
Similarly, other Bluetooth and NFC unlock android supported gadgets can be added under the list of Trusted Devices.
Part 3: Turn On Smart Lock For Android With Trusted Locations
You can also add locations or addresses to Smart Lock Trusted Locations, and the phone unlocks automatically as soon as you arrive at the desired location. For example, you can set up your home or work address under Trusted Locations.
Check current settings first.
On a new Android phone, visit Settings>Personal.
Then Lock Screen and Security.
Then Secure Lock Settings.
Tap Smart Lock.
Tap on Trusted Places.
Tap on Add Trusted Places
- • Initiate the Google Maps app on the Android phone. Make sure the Internet and GPS are on.
- • Pick a place.
- • Click on Settings.
- • Click on Edit home or work. You can now add or edit the required addresses.
- • As an example, click on the Enter work address.
- • You now have the option to type in the address or use the address listed on Google Maps as the required work address.
- • A successful addition is listed and can be edited under the Edit work address.
- • Close the Google Maps app.
- • The work address is automatically propagated and configured with Smart Lock settings.
- • Go back to Settings> Security> Smart Lock> Trusted Places.
- • The work address you added is now listed under Work.
- • However, it is not yet configured as a Smart Lock option. Tap the location once, and it is enabled.
- • The switch along the address to the right turns blue, indicating it is enabled.
- • The work address is now listed under Trusted places for Work.
- • The phone is now configured for the work address and will unlock whenever you are at the location.
- • Since it works on Google Maps, the feature works through an Internet connection.
The feature recognizes your face and then unlocks the Samsung Galaxy Z Flip 5 device. Once you set up the Samsung Galaxy Z Flip 5 device to recognize your face as a trusted face, it will unlock the Samsung Galaxy Z Flip 5 device as soon as it recognizes you.
PRECAUTION: At best, this can be the first level of security, as one who resembles you to some extent can unlock the Samsung Galaxy Z Flip 5 device. Photographs are not stored in the system. The device does hold necessary data to recognize your face, and the security level is determined by how good the Samsung Galaxy Z Flip 5 device is configured. The data is not accessed by any app or loaded onto a Google server for backup.
Setting Up Trusted Face
- • Go to Smart Lock and tap Trusted Face.
- • Tap on Setup. Follow on-screen instructions.
The device begins to gather data about your face. The trusted face icon appears. As a backup, in case Smart Lock does not recognize your face, use the manual system by applying the PIN or password to unlock the Samsung Galaxy Z Flip 5 device.
In case Trusted Face is not required, tap on reset Trusted Face appearing under the Trusted Face menu. Tap on Reset to reset the option.
How To Improve Facial Recognition In Your Bluetooth and Android NFC Unlock Devices
- • If you feel facial recognition is not up to the mark, go to Smart Lock and tap on a Trusted face.
- • Tap on Improve face matching.
- • Tap on Next and follow instructions on the screen to complete the task.
Smart Lock Android is a great feature and is only going to improve on time. With added security measures being introduced by Google for Bluetooth and NFC unlock android devices, including configuration to Google maps and Gmail, the feature may be one of the most important features to overcome constant blocking of devices even in protected places.

### Video on How to Remove Android Lock Screen Without Data LossHow To Unlock Any Samsung Galaxy Z Flip 5 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
While the emergency call bypass for Android method is interesting, it’s largely unreliable and outdated, mainly effective on older Android versions. Modern devices have significantly improved security, making this method obsolete. There are other, more reliable methods for those needing to unlock their phone’s screen.
