How to Unlock Samsung Galaxy A03s If You Forgot The Password

Losing access to your smartphone due to a forgotten password or PIN code can be frustrating. Thankfully, with the Samsung Galaxy A03s, there are a few different methods you can use to regain access even without knowing the password. This guide will walk you through the step-by-step instructions for unlocking a Galaxy A03s that has a forgotten password using both software and hardware-based techniques.

Software-Based Unlocking Methods

Before attempting any hardware unlocking methods, the first step should always be to try resetting the password using built-in software options.

Attempt Password Recovery Through Find My Mobile

If you had the Find My Mobile service activated on your device, you can remotely reset your password online. Simply go to the Find My Mobile website, enter your Samsung account details and follow the onscreen instructions to reset your password.

The benefit of using Find My Mobile is that it allows you to regain access to your device without losing any data. However, the service needs to have been previously setup on the device which is not always the case.

Boot Into Recovery Mode to Factory Reset

If Find My Mobile is not an option, the next software-based method to try is booting your Galaxy A03s into recovery mode and selecting the ‘Factory Data Reset’ option. This will reset your device back to factory default settings, removing your password but also any locally-stored apps and data.

To factory reset from recovery mode:

  1. Turn off your Galaxy A03s
  2. Hold down the Volume Up button and the Side (Power) button at the same time
  3. Once the recovery menu screen appears, use the volume keys to scroll to ‘Wipe data/factory reset’
  4. Select this option and confirm to reset your device

After the reset process completes, your phone will reboot with no password set allowing you to access it again. Just be aware that as warned above, this method also removes all your apps and locally-stored content.

Hardware-Based Unlocking Methods

If none of the software-based options have allowed you to regain access, the last resort is using hardware-based unlocking techniques. These methods require additional tools but can unlock your device regardless of the password.

Unlock Through USB with OEM Unlock

One hardware method that works on many Samsung devices is unlocking through a USB connection if OEM unlock is enabled.

To unlock with this method:

  1. Download and install the required USB drivers on a Windows PC
  2. Turn off your Galaxy A03s
  3. Boot your device into ‘Download mode’ by holding Volume Down + Side button
  4. Use a USB cable to connect the device to your computer
  5. Open the OEM unlock menu and enable the option
  6. Select ‘Start’ to reboot your device unlocked

However, OEM unlock is usually disabled from the factory, preventing this method from working. You’ll need to check if it’s available under Developer Options on your specific A03s device first.

Generate Unlock Codes Through Device Identifier (IMEI)

IMEI unlock codes can successfully unlock many Samsung devices regardless of their current password or PIN code.

To unlock your Galaxy A03s with the IMEI:

  1. Locate your device’s 15-digit IMEI number under About Phone > Status > IMEI information
  2. Use a trusted IMEI unlock code provider to generate an unlock code based on your IMEI
  3. Turn off your device and insert a non-accepted SIM card into the SIM tray
  4. Turn on your device and you will be prompted to enter the network unlock code
  5. Input the unlock code provided and your device will now be network unlocked

The advantage of using the IMEI to generate an unlock code is that it will reliably unlock your device. However, some third-party unlock services do charge a small fee to generate this code.

Alternative Hardware Unlocking With Unlock Boxes

The final hardware-based unlocking option to consider is temporarily unlocking your device using an unlock box or dongle. These tools are connected to your Galaxy A03s via USB and can remove the existing password lock regardless of what code or PIN was previously set.

There are a few trusted manufacturers of Samsung unlock boxes to consider:

The steps to use these tools are:

  1. Purchase an unlock box and install necessary drivers on your Windows PC
  2. Connect the device to your computer via the unlock box/dongle
  3. Run the unlock software and follow prompts to remove lock
  4. Disconnect device and reboot to access your unlocked phone

The limitation of these tools is that temporary unlocks only last for 30 days. However, they provide a quick and cost-effective way to access a locked Galaxy A03s before setting up your new password.

Protect Against Future Lockouts

Once you’ve regained access to your Samsung Galaxy device, it’s crucial you take steps to prevent lockouts from happening again:

  • Always enable Find My Mobile and add a Google account
  • Create a Samsung account and enable backup features
  • Store backup unlock codes, passwords and PINs in a safe place
  • Set up alternate unlocking methods like facial recognition or fingerprints
  • Enable auto data syncing to cloud storage services

Taking preventative measures allows you to securely unlock and recover your device data if the situation occurs again. Avoiding future lockouts gives you confidence your smartphone access and information is protected.
