Modern messaging tools are built around privacy and reliability, but when Google Messages begins sending random texts, it quickly creates serious problems. Users across Pixel, Samsung Galaxy, and other Android devices report that their phones are either pulling old text threads from years past and delivering them to unintended contacts, or transmitting garbled, cipher-like gibberish strings.
The Two Major Variations of the Random Text Bug
1. Historical Message Injection (Privacy Critical)
In this scenario, a user types a standard text—such as replying to a work colleague or confirming an appointment—and upon sending, the application pulls an unrelated, archived conversation bubble from an entirely different contact. Verification codes, personal financial notes, or sensitive past relationship messages have attached themselves to outgoing payloads.
2. RCS Decryption Failures & Gibberish Code
The second form of this issue displays random strings of letters, numbers, and symbols (such as ~#ff0b... or fragmented base64 lines). This occurs when the RCS cryptographic session key becomes desynchronized between sender and recipient, causing the raw encrypted transport payload to render directly on screen instead of plaintext.

Root Causes: Why Google Messages Misroutes Your Data
- Device Migration Artifacts: Google engineers identified that transferring text histories during cloud/cable device setups can corrupt message index tables, causing SQLite databases to cross-reference unrelated chat ID keys.
- Carrier RCS Endpoint Timeouts: When network handshakes stall between Google Jibe servers and carrier IMS infrastructure, outbound message parts reorder incorrectly.
- Corrupted App Cache: Stale runtime storage holding draft states and background push tokens without verifying thread IDs.
- Multipart SMS Concatenation Failure: Older SMS protocols split messages exceeding 160 characters. If a cellular tower drops intermediate User Data Headers (UDH), the receiver’s client reassembles the parts with random fragments.
Diagnostic & Fix Matrix for Google Messages Glitches
| Symptom | Direct Cause | Recommended Fix | Resolution Speed |
|---|---|---|---|
| Old chat auto-inserts into new message | Indexed SQLite table pointer collision post-restore | Update app build via Play Store / Beta channel | Immediate |
| Recipient sees random numbers/letters | End-to-end RCS session decryption handshake timeout | Toggle RCS Chats OFF and back ON | 1–2 mins |
| Draft text persists across unrelated contacts | Stale internal UI cache memory leakage | Clear cache in Android System Settings | 1 min |
| Sent photo is replaced by older saved image | Media attachment cache pointer corruption | Clear storage for Carrier Services & Messages | 3–5 mins |
Step-by-Step Fixes to Stop Random Text Messages
1. Check for Pending App Updates (or Join Beta)
Because this issue stems from an upstream indexing and database bug, applying the latest patch is the only permanent solution:
- Open the Google Play Store.
- Tap your profile icon in the top right > Manage apps & device.
- Install any available update for Google Messages.
- Tip: If an update is not yet available for your device, scroll down the Google Messages store listing and select Join the Beta to receive incoming emergency hotfixes sooner.
2. Reset and Re-Authenticate RCS Service
Rebooting your cryptographic session resolves garbled characters and out-of-order message delivery:
- Open Google Messages and tap your profile avatar.
- Navigate to Messages settings > RCS chats.
- Toggle off Turn on RCS chats.
- Restart your phone, re-open the menu, and switch RCS back to ON until the status displays Connected in green.
3. Clear Cache for Messages & Carrier Services
Eliminate corrupted local index pointers without removing your actual messages:
- Go to your phone’s Settings > Apps > See all apps.
- Select Messages > Storage & cache > tap Clear Cache.
- Go back to the app list, locate Carrier Services, tap Storage & cache, and tap Clear Cache.
4. Safe Device Recovery (When Database Corruption Persists)
If old chats continue to inject themselves into new threads after updating:
- Back up your essential media, photos, and files manually (avoid creating a full local SMS dump if it is already compromised).
- Perform an Android device factory reset.
- Set up the phone clean without selecting “Restore full SMS history from old device” to ensure the corrupted database schema is not re-imported.
🛡️ Critical Privacy Precaution While Waiting for the Full Fix
Always pause and visually review your message preview before hitting send. If a historical message inadvertently attaches and delivers, immediately long-press the message bubble and tap Delete for everyone (if available over modern RCS) to remove it from both ends. For sensitive work or personal exchanges, switch temporarily to Signal or WhatsApp until your device receives the validated patch.
Frequently Asked Questions
Does the random text issue mean my Google account has been hacked?
No. This issue is caused by a local client-side software glitch and database index mismatch on the device, not an unauthorized account takeover, external spyware, or account compromise.
Will clearing my app cache delete my text message history?
No. Tapping Clear Cache removes only temporary files and script pointers. Your texts, multimedia files, and contacts remain completely intact.
Does this error happen over SMS or only RCS?
Reports confirm the bug affects both standard SMS/MMS transmissions and RCS chats. While the decryption gibberish issue is specific to RCS, the old text resurfacing glitch has occurred across all message formats.
