Message Went From RCS to Individual Messages in Thread

Is Google Messages splitting threads into separate conversations instead of keeping your texts together? You might see an RCS chat turn into individual SMS messages, two conversations with the same person, or several copies of one group chat. These problems can have different causes, so the right fix depends on what is happening. Start with your RCS connection and group messaging settings before trying more disruptive troubleshooting.

Last checked: October 11, 2026. Troubleshooting procedures were checked against Google’s official documentation, and the reported split-thread issue was reviewed against published reporting.

Why Your Google Messages Threads Split

Google Messages threads can split when the app handles replies as different conversations instead of continuing the existing history. Sometimes that behavior is expected because of SMS/MMS settings. Other times, it is an RCS connection problem or a software bug.

RCS (Rich Communication Services) sends messages through Wi-Fi or mobile data. It supports features such as typing indicators, read receipts, and higher-quality media sharing. SMS and MMS use different delivery methods and do not provide the same features.

The most common situations to investigate are:

• RCS connection changes: A participant temporarily loses RCS and sends a message through SMS or MMS.
• Mass text settings: Group replies arrive as individual conversations by design.
• Contact or number mismatches: A person uses another number, or their contact details are inconsistent.
• App or migration problems: Conversation history becomes fragmented after changing messaging apps, switching phones, or encountering a Google Messages bug.

These situations can look similar, but they require different solutions. In particular, changing group messaging settings will not necessarily repair duplicate RCS conversations caused by a software defect.

The problem has been reported on Google Pixel and Samsung Galaxy phones. Some affected users previously moved from Samsung Messages to Google Messages or transferred data through Samsung Smart Switch. Others experienced splitting without a recent device change.

Check Whether RCS Is Still On

First, confirm that RCS is enabled and connected in Google Messages. An interrupted or unverified RCS connection can cause messages to use SMS/MMS instead.

The menu is usually labeled RCS chats in current Google Messages versions. Some devices or older interfaces still display Chat features.

Verify Chat Features

Use these steps to inspect the connection without changing your conversation history.

1. Open Google Messages on your Android phone.
2. Tap your profile picture or initial in the upper-right corner.
3. Select Messages settings.
4. Tap RCS chats. If that option is not available, look for Chat features.
5. Confirm that RCS chats are enabled.
6. Read the connection status shown on the screen.

Google’s official RCS status guidance explains the available connection states and what they mean.

If your status says Connected, RCS is available for conversations with compatible participants. However, that does not guarantee every existing conversation will be free of threading bugs.

Confirm RCS Status

The status shown in Google Messages helps separate connection problems from other causes of thread splitting.

When the status remains Connecting or Trouble connecting, check your internet connection and confirm that your phone can receive SMS messages for verification.

Also confirm that Google Messages is your default SMS app and that the app is updated through Google Play.

If the carrier has disabled RCS, contact the carrier. Google’s RCS connection troubleshooting checklist covers these checks.

For a group conversation, everyone needs compatible, working RCS service to communicate as an RCS group. A temporary loss of connection can change how individual replies arrive.

Do not repeatedly switch RCS off and on as a first troubleshooting step. Google warns that disabling RCS can remove you from existing RCS group chats.

Check for Contact and Number Mix-Ups

Contact information is another place to check when two conversations appear for the same person. A changed phone number, duplicate contact entry, or incorrect country code can create confusion about which number a thread belongs to.

However, two identical threads do not automatically mean you have duplicate contacts. The reported Google Messages bug can produce separate conversations with the same participants.

To rule out a contact problem:

1. Open the affected conversation and inspect the actual phone number in its details.
2. Compare that number with the original conversation.
3. Open your Contacts app and look for duplicate entries or old phone numbers.
4. Confirm the country code is correct, such as +1 for a US number.
5. Merge or correct duplicate contact records only after confirming they belong to the same person.
6. Ask the recipient whether they recently changed numbers, phones, or messaging apps.

Google’s Messages troubleshooting guide recommends verifying phone numbers, checking country codes, and correcting contact entries when messages fail for specific recipients.

If one conversation uses an old number and another uses a new number, correcting the contact details may prevent future confusion. It will not necessarily combine the existing message histories.

When both conversations show exactly the same number and RCS status, consider an app-level threading problem rather than assuming the contact is wrong.

Clear Messages Cache and Start Fresh

If the settings and contact details look correct, try a low-risk app refresh. Clearing temporary cache files may help with local app problems, although it is not a confirmed fix for Google’s acknowledged split-thread bug.

There is an important difference between Clear cache and Clear storage. The first removes temporary files. The second removes app data and creates a greater risk of losing information or settings.

Clear App Cache

Clearing the Google Messages cache is a reasonable troubleshooting step when conversations behave inconsistently or the app is unusually slow.

1. Open your phone’s Settings app.
2. Select Apps.
3. Find and select Google Messages.
4. Open Storage & cache or the equivalent storage menu.
5. Tap Clear cache.
6. Reopen Google Messages and check the affected conversation.

The exact labels can differ between Samsung, Pixel, and other Android phones.

According to Google’s Android storage guidance, clearing cache deletes temporary app data. It is not the same operation as deleting stored conversations.

After clearing the cache, check whether RCS still shows Connected and whether new replies remain in the expected thread.

If the issue continues, there is no need to repeat cache clearing every day. Move to the remaining checks instead.

Reset Message Storage

A full Google Messages storage reset is more disruptive than clearing its cache. It should not be treated as a routine fix for conversation splitting.

If you are considering a full reset, verify your device backup first:

1. Open Android Settings.
2. Go to Google > All services > Backup, if available on your device.
3. Review the backup details and confirm messages are included.
4. Use Back up now if your device offers that option.
5. Check that any important conversations or media are available through a reliable backup before making destructive changes.

Google’s Android backup and restore documentation describes SMS/MMS backups and RCS message backups when using Google Messages.

A backup does not guarantee that all message data or conversation organization can be restored on every device. Restoration also depends on the phone, Android version, and backup contents.

For ordinary thread splitting, stop at cache clearing unless official support recommends a deeper reset for your specific case.

Restart RCS Session

If RCS is stuck connecting, refreshing the phone’s network and messaging services may help it reconnect. Start with a normal device restart instead of repeatedly disabling RCS.

1. Close Google Messages.
2. Restart your Android phone normally.
3. Connect to working Wi-Fi or mobile data.
4. Open Google Messages and inspect the RCS status.
5. Wait for the status to return to Connected before testing a compatible conversation.

If the status remains stuck during verification, use the connection troubleshooting steps described earlier.

When a group member temporarily loses RCS, the member’s connection may recover and group messaging may return to normal. However, restarting your phone cannot guarantee that already duplicated conversations will merge.

If the status is Connected and fresh replies still create new threads, investigate the group settings or known software bug.

Why Group Chats Split Into Separate Threads

Google Messages group chats can split for two different reasons: normal SMS/MMS group settings and RCS-related problems. The most useful check is whether replies are arriving as individual SMS messages or as duplicate group conversations containing the same participants.

Check the Group MMS and Mass Text Setting

The Mass text setting intentionally sends separate SMS messages and receives individual replies. If you want a traditional SMS/MMS group conversation, use Group MMS instead.

1. Open Google Messages.
2. Tap your profile picture or initial.
3. Go to Messages settings > Advanced.
4. Select Group messaging.
5. Choose Send an MMS reply to all recipients (group MMS) instead of Mass text.
6. Return to your conversations and test group messaging.

Google explains this distinction in its official group messaging guide.

Group MMS lets participants reply within a shared MMS conversation. Mass text is intended for sending to multiple people while collecting their replies individually.

This setting applies to SMS/MMS group behavior. It is not a guaranteed repair for duplicate RCS group threads.

Check Whether Group Members Have Working RCS

An RCS group depends on the messaging compatibility and connection of its members. If someone temporarily loses RCS, their device may send an individual SMS or MMS instead of replying inside the existing group.

Google’s troubleshooting documentation explains that the group conversation will usually return to its normal behavior after the sender reconnects to RCS.

To identify this situation, check whether the affected member has a working data connection and enabled RCS service.

You can also start a new conversation in Google Messages and inspect which recipients display an RCS label. An iPhone user can appear as RCS-compatible when their device and carrier support the feature.

Do not assume that every conversation involving an iPhone must use SMS or MMS. RCS is supported on compatible iPhones, although availability depends on the device, software, carrier, and region.

Recognize Duplicate Group Threads Caused by a Bug

A separate problem occurs when Google Messages creates another group thread with the same people, even though the original conversation still exists.

Signs of this issue include:

• New replies appear in a second conversation with identical members.
• The original group remains visible but stops receiving some replies.
• Several duplicate group conversations appear over time.
• Both conversations appear to support RCS.
• The problem continues after ordinary connection and group-setting checks.

Reports have described seven or more copies of a group conversation. This pattern differs from the expected individual SMS replies produced by Mass text.

Deleting the duplicate conversation is not a reliable solution. Some affected users report that the thread reappears when another message arrives.

Google’s Split-Thread Bug Update

Google acknowledged a group conversation splitting problem in August 2026. The issue involves existing group chats creating additional threads with the same participants, leaving message history scattered across separate conversations.

According to Android Authority’s August 27, 2026 report, Google confirmed that it was investigating the group-thread problem and requested user feedback containing #splittingthreads.

That report also documented:

• Problems affecting both Pixel and Samsung devices.
• Some cases appearing after Samsung Smart Switch migrations.
• Other cases occurring without a recent phone change.
• Individual RCS conversations splitting into separate threads with identical contact information.
• Users seeing messages move between RCS and SMS/MMS around the time of a split.

Google’s acknowledgment specifically covered group conversations. It did not establish that every individual-chat splitting report had the same cause.

Likewise, switching between RCS and SMS/MMS was observed in some reports, but it was not confirmed as the cause of the software bug.

The August report did not provide a specific release date for a dedicated split-thread fix. A confirmed completion date for that particular repair was not established in the sources reviewed for this article.

How to Report a Split-Thread Problem

If group chats keep splitting after you have checked the settings, send a detailed feedback report to Google.

1. Open Google Messages.
2. Tap your profile picture or initial.
3. Select Help & feedback.
4. Tap Send feedback.
5. Describe whether the problem affects one person or a group.
6. Include the hashtag #splittingthreads.
7. Explain your phone model, whether you recently switched devices, and whether both threads show RCS.
8. Add screenshots if they help explain the issue, while avoiding unnecessary exposure of private message content.
9. Send the feedback report.

Google documents the reporting process in its Google Messages feedback instructions.

When reporting a recurring problem, mention which troubleshooting steps you already tried. This helps distinguish a group-setting problem from the duplicate-thread behavior Google has been investigating.

What to Do While the Problem Continues

If the same participants keep appearing in separate RCS threads, changing settings may not solve the underlying bug.

Keep Google Messages updated, preserve important conversation history, and avoid repeatedly deleting or resetting message data.

If a duplicate thread contains useful messages, leave it intact until you understand what is stored there. Archiving a conversation may make the inbox easier to manage, but archiving is not the same as merging two histories.

You can also compare the participants and phone numbers in each thread to rule out a genuine contact change.

If other messaging features also fail, contact your mobile carrier or device support provider to check for a service issue. However, carrier troubleshooting cannot guarantee a fix for an app-level thread duplication bug.

Frequently Asked Questions

Why Are My Texts Sending as RCS to One Person?

Your texts send as RCS to one person because both participants have compatible, connected RCS service. Other contacts may receive SMS or MMS because their RCS service is unavailable or disabled. This difference is normal. If RCS worked before but suddenly stopped, check the conversation type, connection status, and recipient compatibility.

Why Are My Group Messages Sending to Individuals on My Android Phone?

Your group messages may reach individuals because Mass text is enabled instead of Group MMS. Change the setting under Messages settings, Advanced, and Group messaging. A temporary RCS connection loss can also cause individual SMS/MMS replies. If identical group chats keep appearing, the cause may be the reported Google Messages splitting bug.

Why Do Some of My Text Messages Say RCS and Others Don’t?

Some messages say RCS because the conversation supports internet-based RCS messaging, while others use SMS or MMS. Compatibility, connection status, and recipient settings determine the available method. Supported iPhones can also use RCS, so an iPhone contact does not automatically mean SMS. Check the compose bar to identify the current sending method.

Why Do I Have Two Separate Conversations With the Same Person in Messages Android?

Two conversations with the same person may result from different phone numbers, contact changes, app migration, or a Google Messages threading bug. Compare the actual numbers and RCS status in both threads. If they match exactly, a software issue becomes more likely. Avoid deleting either conversation before preserving important messages.

Does Clearing Google Messages Cache Delete Text Messages?

Clearing Google Messages cache removes temporary files rather than your saved text messages. It is different from Clear storage or Clear data, which removes app data and can create a risk of losing information. Always choose the correct option. Cache clearing may help temporary app problems but is not a guaranteed solution for split threads.

Can Google Messages Merge Two Split Conversations?

Google Messages does not provide a generally documented, reliable manual merge feature for duplicate conversation histories. Correcting contact details or connection settings may help prevent future problems, but existing messages may remain separate. Do not assume that deleting, archiving, or resetting conversations will combine them. Preserve both histories while investigating the cause.

Conclusion

When Google Messages splits RCS or group conversations, begin by checking RCS status, group MMS settings, and contact numbers. Clear the cache only if the basic checks do not help, and protect your messages before considering any storage reset.

If the same RCS participants keep appearing in duplicate threads despite correct settings, the problem may be Google’s acknowledged software bug. Preserve the affected conversations, submit a report with #splittingthreads, and keep the messaging app updated.
