Top 3 Ways to Bypass A155F FRP Samsung Lock

Part 1. What Is Samsung A155F FRP Lock?

The Samsung A155F FRP lock (Factory Reset Protection) is a security feature on the Samsung Galaxy A15 that protects your data if the phone is reset without your permission. It turns on automatically when you sign in with a Google account and set a screen lock.

If someone tries to reset the phone using Recovery Mode or other unofficial ways, the FRP lock will ask for the Google account details that were last used on the device. This helps prevent unauthorized access if the phone is lost or stolen. However, it can also cause issues if you forget your login details or buy a used phone with FRP still active.

Part 2. When and Why You Might Need to Bypass FRP

You might need to bypass the Samsung A155F FRP lock in the following situations:

• Bought a used phone: If the previous owner didn’t remove their Google account before resetting, the FRP lock will stop you from using the phone.
• Forgot Google details: After a factory reset, if you can’t remember the account info linked to the phone, you’ll be locked out.
• “Verify your account” screen: This shows up after a reset when FRP is on, and you must enter the correct Google account to continue.

Part 3. Preparations Before Samsung A155F FRP Bypass

But before you bypass the A155F FRP lock, there are some preparations to do. Otherwise, you might not be able to unlock your Samsung phone or risk damage to it. Here are the steps to take:

• Check model: Make sure the phone is a Samsung Galaxy A15 (A155F).
• Wi-Fi: Stable intercom is needed for downloads and some bypass steps.
• Battery: Charge the phone fully to avoid interruptions.
• Unofficial tools are risky: Dubious third-party tools can carry malware or brick the phone.
• Data loss possible: Back up anything important before trying a bypass.
• Choose a bypass approach: Use an A155F FRP unlock tool, flash special firmware, or combination files with Odin. You can also employ the test-point method (hardware access to the motherboard) and PC/USB methods using specific software.

• Choose the Android OS version of your Samsung phone. If you’re doubtful, choose “All Android versions.” Hit “Remove Now.”

• Once the FRP lock is removed, your Samsung phone A15 will reboot. You can set it up without needing to verify your Google account.

  

Method 2. FRP Bypass via Emergency Dial or Hidden Settings (If Applicable)

If you want to bypass A155F FRP without PC, you can employ the emergency dial or hidden Settings to remove the FRP lock from your Samsung phone. The emergency dial method functions best on older Android 5 or earlier versions, where entering certain codes could crash the system or open hidden menus. On Android 6 and newer, stronger security makes this trick much less effective.

Whereas the hidden settings method functions mainly on Android 9 and 10. It involves downloading a “Hidden Settings” app from the Galaxy Store to access hidden menus and try setting a new screen lock. However, it may not support all devices since results can vary by phone model and software version. Here’s how to employ both emergency dial and hidden settings methods to bypass FRP lock on your Samsung A15:

Using Emergency Dial:

Step 1: Turn on your Samsung phone. On the lock screen, click “Emergency Call.”

Step 2: Type several asterisks (*), then copy and paste them repeatedly until the phone slows or stops highlighting them.

Step 3: Head to the lock screen. Open the “Camera app. Next, swipe down to access the notification panel.

Step 4: Click the “Settings” icon. When a text box appears, paste the asterisks again until the screen crashes.

Step 5: The camera screen will enlarge, then crash. Afterward, the home screen will appear, bypassing the FRP lock and giving you access to the phone. But this method will only temporarily remove the FRP lock.

Using Hidden Settings:

Step 1: Open the Play Store. Head to the “Galaxy Store.” Then, download the “Android Hidden Settings” app.

Step 2: In the app, search for “screen lock.” Then, tap “Choose screen lock.” Set a PIN/pattern/password.

Step 3: Head to the “Wi-Fi page” on your Samsung phone. Tap “Next.” The phone will update. Accept Google’s terms when prompted.

Step 4: Tap” Next.” Then, click “Finish.” Your Samsung phone will reboot, and (if successful) FRP will be bypassed.

Method 3. Contact Samsung Support or Visit an Authorized Service Center

Going to Samsung support or an authorized service center is the safest way to remove FRP on your A155F if nothing works out in your favor. Trained technicians use official methods that avoid damage, keep your warranty intact, and protect your data.

But they’ll ask for proof of ownership (receipt/invoice) to prevent misuse. To proceed, find a nearby authorized Samsung service center, bring your proof of purchase, and contact Samsung support for instructions. However, this method won’t work if you lack the proof of purchase.

Part 5. Important Notes and Warnings For Bypassing Samsung A155F

Here are some important notes and warnings you must keep in mind before you bypass the A155F FRP lock:

• Don’t unlock phones you don't own: Bypassing FRP on a stolen or unapproved device is illegal and ucomhical.
• May void warranty/break terms: Bypass methods can cancel your warranty or violate manufacturer/Google terms.
• Risk of data loss: You may lose data during the process. So, back up anything important first.
• Security risk from unofficial tools: Third-party tools can carry malware or compromise your device.
• Can make the phone unstable or damaged: Incorrect procedures can corrupt software or brick the device.
• Prevent it next time: Always remove your Google account before doing a factory reset.
• Ask Samsung if unsure: Use Samsung support or an authorized service center for safe, official help.
• Try alternatives first: Contact the previous owner and ask them to remove the device from their Google account remotely.

Conclusion

The Samsung A155F FRP lock helps protect your data, but it can block access if you forget your Google login or get a used phone that wasn’t reset correctly. There are different ways to remove it, but some are only compatible with older Androids, while others require proof of purchase.

But a tool like Tenorshare 4uKey for Android doesn’t require proof of purchase, or a Google account and password to bypass FRP lock. It’s compatible with many Android brands and supports both old and newer Android versions.
