Unraveling LOS 22.2 SMS Messaging Issues on Pixel 5: A Deep Dive for [Magisk Modules] Users

Navigating the complexities of mobile operating systems, particularly after a significant upgrade, can often present unforeseen challenges. For users of LineageOS, especially those on newer versions like LOS 22.2, encountering persistent SMS messaging issues can be a source of considerable frustration. This article aims to provide an in-depth exploration of these problems, specifically addressing the experience of users with the Pixel 5 device, and offering comprehensive solutions and insights, drawing upon our extensive knowledge at Magisk Modules and the Magisk Module Repository.

It’s a common scenario: after a successful upgrade from a stable previous version, such as LOS 18.1, to the latest iteration, users expect a seamless experience. However, the reality can sometimes be starkly different. The specific issue described, where sending texts to certain contacts results in error messages like “Unable to send message” or “Could not start a conversation,” is a particularly vexing one. This isn’t a universal failure; it targets specific individuals within the address book, hinting at a more nuanced problem than a complete system breakdown.

We understand the importance of reliable communication, and SMS messaging remains a cornerstone for many users. When this core functionality falters, it impacts daily interactions, from casual conversations to critical notifications. Our goal here is to dissect the potential causes of these LOS 22.2 SMS messaging issues on Pixel 5 and provide actionable steps for resolution, leveraging the power and flexibility offered by the Magisk framework.

Understanding the Scope of LOS 22.2 SMS Messaging Problems

The user’s report highlights a critical detail: the failure is not absolute but rather selective. This means that the underlying SMS infrastructure is likely functional in broad strokes, but specific interactions are being blocked or misinterpreted. When you attempt to send a message to a particular contact, and the system responds with “Unable to send message” or the equally unhelpful “Could not start a conversation,” it suggests that the path to that recipient’s number is being obstructed at some level within the operating system or the messaging application.

This selectivity is key. If all SMS messages were failing, we might immediately suspect a problem with the baseband, the modem firmware, or a general network configuration error. However, the fact that some contacts can receive messages while others cannot points towards issues with:

The initial troubleshooting steps mentioned – clearing storage and cache, and checking permissions – are indeed standard and effective for many app-related problems. However, when these don’t resolve the LOS 22.2 SMS messaging issues for Pixel 5 users, it necessitates a deeper dive, often into areas where root access and tools like Magisk can provide a more granular level of control and insight.

Deep Dive into Potential Causes and Solutions

Let’s break down the potential culprits for these persistent SMS messaging issues on LOS 22.2 for Pixel 5 users and explore a range of advanced solutions.

#### Contact Data Corruption and Normalization

The phone’s address book is a complex database. When you add a contact, information like their name, phone number, email, and other details are stored. Phone numbers, in particular, need to be in a format that the telecommunications network can understand. This usually involves an international prefix (like +1 for North America), followed by the area code and the local number.

Potential Problem:

Solutions:

  1. Manually Verify and Reformat Contact Numbers:

    • Go to your Contacts app.
    • Locate one of the contacts you are experiencing issues with.
    • Edit the contact and ensure the phone number is formatted with a leading plus sign and the country code (e.g., +1xxxxxxxxxx for the US). Remove any extra spaces, hyphens, or parentheses.
    • Save the contact and try sending an SMS to them again.
    • Repeat this for all affected contacts. While tedious, this direct approach can often pinpoint the issue.

  2. Utilize a Contact Management App:

    • There are various third-party contact management apps available on the Play Store (or F-Droid for open-source options) that specialize in cleaning and de-duplicating contacts.
    • These apps can automatically identify and correct formatting errors in phone numbers.
    • Crucially, before using any such app, ensure you back up your contacts! You can typically export your contacts as a .vcf file from the Contacts app.

  3. Export, Clean, and Re-import Contacts:

    • Export all your contacts from the default Contacts app into a .vcf file.
    • Open this .vcf file using a text editor or a dedicated VCF editing tool on your computer.
    • Carefully review and edit the phone number fields, ensuring they follow the TEL;TYPE=CELL:+<country_code><number> format.
    • Remove any extraneous characters or formatting.
    • Once cleaned, delete all contacts from your phone (after backing them up!) and then re-import the cleaned .vcf file. This is a more robust method for ensuring data integrity.

#### Messaging App Cache and Data Reinitialization

While you’ve mentioned clearing cache and storage, sometimes a deeper reset is required. This involves not just clearing the temporary files but also resetting the application’s configuration to its default state.

Potential Problem:

Solutions:

  1. Force Stop and Clear Data (More Aggressive Reset):
    • Navigate to Settings > Apps > See all apps.
    • Find the Messaging app.
    • Tap on Storage & cache.
    • Tap on Clear storage (this is more comprehensive than just clearing cache).
    • Important: This will reset the app to its default state, meaning all your existing message threads will be removed from the app’s interface. Your messages are typically stored in a database, and this action clears the app’s access and configuration to that database. Ensure you have a backup of your SMS messages if you are concerned about losing them, using apps like “SMS Backup & Restore.”
    • After clearing storage, reboot your Pixel 5.
    • Open the Messaging app again and try sending an SMS to a problematic contact. You will likely need to re-grant permissions.

#### LineageOS 22.2 Specific SMS/MMS Service Bugs

It’s possible that the upgrade to LOS 22.2 has introduced a bug within the core SMS/MMS handling services of the operating system itself. These are the background processes that manage sending and receiving messages.

Potential Problem:

Solutions (Leveraging Magisk for Deeper Access):

Since we are operating on a custom ROM like LineageOS, and the issue persists after standard troubleshooting, we can explore more advanced solutions, particularly those that can be implemented with root access via Magisk.

  1. Check for System Updates within LineageOS:

    • While you’ve upgraded to 22.2, there might be incremental updates or patches released by the LineageOS developers addressing known bugs.
    • Go to Settings > System > System update within your LineageOS settings and check for any available updates. Installing these might resolve the issue if it’s a known bug fixed in a subsequent build.

  2. Utilize Magisk Modules for SMS/MMS Fixes (If Available):

    • The Magisk Module Repository is a treasure trove for system-level customizations and fixes. It’s possible that the community has developed modules specifically to address common SMS/MMS issues on various Android versions and devices.
    • Procedure:
      • Open the Magisk app.
      • Go to the Modules tab.
      • Tap on “Install from storage.”
      • Browse to a downloaded Magisk module ZIP file.
      • Alternatively, use the “Download” tab within the Magisk app to search for relevant modules. Search terms could include “SMS fix,” “MMS fix,” “LineageOS SMS,” or “Pixel 5 SMS.”
      • Critical Consideration: When installing Magisk modules, always proceed with caution. Read the module’s description carefully, check its compatibility with your Android version (LOS 22.2) and device (Pixel 5), and look for community feedback or support threads.
      • Recommended Modules (Hypothetical, as specific modules change): While we cannot guarantee specific modules will exist for this exact problem, historically, modules that tweak telephony services, framework configurations, or carrier configurations have been developed. Look for modules that claim to improve messaging stability or fix specific network communication errors.
      • After installing a module, reboot your device. Test SMS functionality. If it doesn’t help or causes new issues, uninstall the module via the Magisk app.

  3. Re-flash LineageOS 22.2 (Clean Install):

    • If no specific module addresses the issue and the problem seems deeply rooted in the OS installation, a clean re-flash of LineageOS 22.2 can be a highly effective, albeit time-consuming, solution.
    • This process will wipe your data. Therefore, a comprehensive backup of all your important data (photos, videos, documents, apps, and SMS messages) is absolutely essential.
    • Procedure:
      • Boot into your custom recovery (like TWRP).
      • Perform a Wipe (Factory Reset) which typically includes wiping Data, Cache, and Dalvik/ART Cache.
      • Flash the LineageOS 22.2 ZIP file.
      • Flash GApps (if you use them).
      • Flash Magisk ZIP (if you want root access).
      • Reboot your device.
      • After the initial setup, restore your backed-up data and test SMS functionality.

#### Permissions and Background Activity Deep Dive

While you’ve confirmed permissions are set correctly, sometimes the issue lies in how these permissions are enforced or interacted with by other system processes.

Potential Problem:

Solutions:

  1. Disable Battery Optimization for Messaging App:

    • Go to Settings > Apps > See all apps.
    • Find the Messaging app.
    • Tap on Battery.
    • Select “Unrestricted” or “Don’t optimize” to ensure it can run freely in the background.
    • Repeat this for the Contacts app as well.

  2. Check for Interfering Apps:

    • Consider any recently installed apps, especially those that might interact with contacts, messages, or system services.
    • If you suspect a particular app, try uninstalling it temporarily and see if the SMS issue resolves.
    • A safe mode boot can help diagnose this. Reboot your Pixel 5 and when the boot animation appears, long-press the volume down button. If SMS works in safe mode, it strongly indicates a third-party app is causing the conflict.

#### SIM Card and Carrier Settings

Though less likely if only specific contacts are affected, it’s worth a quick verification.

Potential Problem:

Solutions:

  1. Reset Network Settings:

    • Go to Settings > System > Reset options.
    • Tap on “Reset Wi-Fi, mobile & Bluetooth.”
    • This will reset all network-related settings, including Wi-Fi, mobile data, and Bluetooth. You will need to re-enter Wi-Fi passwords and re-pair Bluetooth devices.
    • Reboot your device after this reset and test SMS.

  2. Reseat the SIM Card:

    • Power off your Pixel 5.
    • Use a SIM ejector tool to carefully remove the SIM card tray.
    • Remove the SIM card, check it for any visible damage, and then reinsert it firmly into the tray.
    • Insert the tray back into the phone and power it on.

#### Testing with Alternative Messaging Apps

To further isolate whether the issue is with the stock LOS Messaging app or a system-wide problem, try an alternative.

Solution:

  1. Install a Reputable Third-Party Messaging App:
    • Download and install an app like Signal or Google Messages from the Play Store.
    • Grant the necessary permissions to the new app.
    • Try sending messages to the problematic contacts using this alternative app.
    • If messages send successfully with a different app, it strongly indicates the problem lies with the default LOS Messaging app or its integration with LOS 22.2. You might then consider using the alternative app or looking for solutions specific to the stock LOS Messaging app.
