Samsung A15 Phone Deleting Random Messages in Google Messages App: Causes and Fixes

Users of Samsung Galaxy A15 smartphones have reported that the Google Messages app is deleting text messages randomly, a problem that has emerged following recent software updates and has prompted discussions in online support communities.

The issue was first highlighted in a Google Alert discovery on April 24, 2026, which pointed to a user report describing how their Samsung A15 began deleting messages in the Google Messages app without user intervention. The report noted that the deletions affect both individual messages and entire conversation threads, occurring unpredictably and without a clear pattern tied to message age or content.

Similar complaints have surfaced in Samsung’s official community forums, where users with devices running Android 15 and One UI 7 have described the Messages app incorrectly marking old messages as unread multiple times per day. One user reported that despite deleting the messages, clearing the app cache, and restarting the device, the issue recurred several times daily, suggesting a deeper software conflict rather than a temporary glitch.

Technical analysis from device support sources indicates that automatic deletion settings within the messaging app could contribute to message loss. On Android devices, a feature labeled “Delete old messages” under Message History settings may be enabled by default, causing the system to remove older texts to free storage space. Disabling this option is recommended as a first step to prevent further loss.

App data corruption is another potential cause identified in troubleshooting guides. Clearing the cache and storage for the Google Messages app via Settings > Apps & Notifications > Messages > Storage & Cache can reset the application and resolve conflicts caused by temporary files. This process does not delete user messages but may restore normal app behavior if corrupted data is interfering with message handling.

Cloud backup status also plays a critical role in message recovery. Users who had previously enabled SMS backup through Google Drive may be able to restore lost messages by accessing the Backups section in the Google Drive app. However, without an active backup, deleted messages cannot be recovered, underscoring the importance of regular synchronization with cloud services.

Third-party recovery applications have been cited as a last-resort option for retrieving deleted texts, though their effectiveness varies and they require careful use to avoid compromising device security or data integrity. These tools scan internal storage for remnants of deleted data but are not guaranteed to recover messages, especially if new data has overwritten the original storage sectors.

The timing of the issue coincides with the rollout of Android 15 and One UI 7 updates to Samsung devices, including the A15 model. While Samsung has not issued an official statement confirming a widespread bug in the Messages app, the concentration of reports following the update suggests a possible software incompatibility or system-level conflict affecting message persistence.

Until an official fix is released, users are advised to verify their message history settings, clear app cache and data, confirm cloud backup status, and avoid relying solely on the device for long-term message storage. Regular manual backups or synchronization with secondary services may help mitigate the risk of unexpected data loss.
