How to Unlock Text Messages on Android (Simple Guide)

When you use your Android device to send and receive text messages, you may notice a feature that allows you to “lock” specific messages. This lock function is designed to protect important texts from accidental deletion.

What does it mean to lock a text message?

  • Protection: Locking a message prevents it from being deleted.
  • Persistence: Even if you delete a conversation, the locked messages within it will remain.
  • Identification: Locked messages often have a lock icon or symbol to distinguish them.

How to recognize a locked message?
Look for these indicators in your messaging app:

  • A small padlock icon next to the message
  • The message is unable to be selected for deletion

Why would you lock a message?

  • To preserve evidence of a conversation
  • To keep important information, like a code or a date, easily accessible

Limitations of locking messages:

  • It does not encrypt the text or prevent others with access to your phone from reading it.
  • It simply adds a layer of security against unintended removal.

To lock or unlock a text message on an Android device, press and hold on to the message until a menu appears. Then, select the ‘lock’ or ‘unlock’ option accordingly.

Prerequisites for Unlocking Messages

Before you attempt to unlock text messages on your Android device, certain prerequisites are necessary to ensure a smooth process.

  • App Permissions: Your messaging app requires specific permissions to function correctly. Confirm that it has access to SMS/MMS and storage.
    • Go to Settings > Apps > Your Messaging App > Permissions.
  • Device Security: Knowing your security credentials, such as a PIN, password, fingerprint, or pattern, is essential. You will need these to unlock your device and access locked messages.
  • Software Status: Ensure your Android device is running an up-to-date operating system. Outdated systems may encounter more significant issues with unlocking messages.
  • Backup Plan: Have a backup of your text messages, if possible, to avoid data loss. You can use cloud services like Google Drive or an external backup.
  • Technical Know-How: Familiarize yourself with basic troubleshooting steps, as you may need to address simple operating glitches that might be hindering access.

Primary Methods to Unlock Text Messages

To access your locked text messages on an Android device, you can either use the default SMS application or opt for third-party SMS applications. Each method offers distinct ways to unlock messages, ensuring the privacy of your communications.

Using the Default SMS App

If you have set up a lock on your text messages directly within your device’s default messaging app, you can unlock them by entering the correct password, PIN, or biometric validation such as your fingerprint or facial recognition. Follow these steps:

  1. Access the lock screen or the locked message.
  2. Input your passwordPIN, or use your fingerprint or facial recognition if set up.
  3. Upon successful authentication, you will gain access to your locked text messages.

Via Third-Party SMS Applications

Third-party SMS applications often provide their security features, which may include additional methods for message locking:

  • Download and install a reputable third-party SMS application from the Google Play Store.
  • Navigate to the app’s settings or security menu.
  • Enable the locking feature (Lock or Security) and set a passwordPIN, or biometric lock.
  • Locked messages can be accessed by entering the set credentials within the app.

Unlocking Messages from Particular Senders

If you’ve discovered that messages from certain contacts are not appearing in your inbox, it may be that you have inadvertently blocked these senders. To unlock text messages from specific senders on your Android device, follow these steps:

  1. Open the Phone App: Locate the standard Phone app on your Android device, typically symbolized by a green icon with a phone silhouette.
  2. Access Your Contact List: Within the app, navigate to your contact list and select the contact you wish to unblock.
  3. Unblock the Contact: Tap on the contact’s name to open their details. Here, look for an option labeled Unblock or Remove from blacklist. Select this option to allow messages from this contact to reach your inbox once again.

If you have a messaging app that’s separate from your standard phone app:

  1. Open the Messaging App: Start by opening your messaging application where you normally view text messages.
  2. Settings and More: Tap on the Settings gear icon, which is often located in the corner of the app, or through the menu denoted by three dots.
  3. Blocked Contacts: Within settings, you may find an option such as Blocked contacts or Spam & blocked. Select this to view a list of blocked numbers.
  4. Unblock the Sender: Within this list, locate the sender whom you wish to receive messages from and tap Unblock.

Recovering Deleted Text Messages

If you’ve accidentally deleted crucial text messages on your Android device, there are methods to potentially recover them.

Before proceeding, note: Recovery is not guaranteed and often depends on whether new data has overwritten the space of the deleted texts.

Check Your Backups

Most Android devices are set up to back up data to Google Drive. Follow these steps to restore a backup:

  1. Navigate to Settings on your phone.
  2. Tap on System and select Backup.
  3. Ensure the Backup by Google One option is toggled on.
  4. If a recent backup is available, use the Restore option to retrieve your messages.

Utilize Google Messages

When using Google Messages as your default SMS app, archived messages can be easily retrieved:

  1. Launch Google Messages.
  2. Tap on the profile icon in the top-right corner.
  3. Select Archived to view messages.
  4. To unarchive a message, tap and hold it, then choose ‘Unarchive’.

Using a Computer

You can also try to retrieve messages through a web-based interface:

  1. Visit
  2. Pair your phone with your computer following the on-screen prompts.
  3. Click the menu icon and choose Archived.
  4. Unarchive the messages as needed.

Usage of Encryption and Decryption Apps

When seeking to enhance the privacy of your text messages on an Android device, utilizing encryption and decryption applications is a fundamental approach.

These apps ensure that only the sender and the recipient have access to the contents of a message.

Selection of an App: Choose a reputable encryption app, such as Signal.

This app encrypts your messages and calls, providing a secure communication channel.

Installation and Setup: After selecting an app, install it from the Google Play Store.

During setup, you will be prompted to create a passphrase or use biometric authentication to encrypt your messages.

Sending Encrypted Messages:

  • Open the app.
  • Create a new message by tapping the pencil icon.
  • Select a recipient who also uses the same encryption app.
  • Your messages will now be encrypted.

Receiving Encrypted Messages:

  • Notification of a new message will appear.
  • Unlock the app using your passphrase or biometric data.
  • Read the encrypted message safely, knowing that it is secure from third parties.

Key Management:

  • Safeguard your encryption keys – do not share them.
  • Regularly update your passphrase for additional security.

Using such apps may require both parties to have the same application and have the chat features enabled.

End-to-end encryption protects messages from unauthorized access during transmission.

Remember, the strength of encryption relies on the integrity of your device’s security settings and the secrecy of your chosen passphrase or biometric unlock features.
