Text messages belong to your messaging app so a scan of an SD card can't bring them back. Open Trash in Google Messages first because deleted conversations remain there for 30 days. Restore a Google backup or your messaging app's own backup next. For photos, videos and files that sat on the card, stop using it and scan it on a computer. Never save recovered files back to the same card.
You deleted something and there is no backup. Before you reach for software, find out what the SD card contains. That answer decides which recovery route can work.
Android apps store private data in the phone's internal storage. Android Developers states that a removable SD card sits apart from that storage. See Android Developers guide to data and file storage.
Can You Recover Deleted Messages From an SD Card?
Only if a messaging app exported them to the card. Messaging apps store conversations in app storage on the phone. Scans of a card find photos, videos and files instead of texts.
| What You Lost | Where to Look | Works Without a Backup? |
|---|---|---|
| Text messages | Google Messages Trash, then a Google backup | Trash works for 30 days |
| Chat app messages | The chat app's own backup | Only if a backup exists |
| Photos and videos | The SD card on a computer | Yes, until new data overwrites them |
| Documents | The SD card on a computer | Yes, until new data overwrites them |
How do You Restore Deleted Text Messages on Android?
- Open Trash in Google Messages. Google states that trashed conversations can be restored for 30 days. Touch and hold a conversation and tap the restore icon. See Google guide to the Trash folder in Google Messages.
- Restore your Google backup. Google backs up SMS and MMS messages automatically. RCS messages back up through Google Messages. Follow the on screen steps during setup or after a factory reset. See Google guide to backing up and restoring Android data.
- Check your chat app. Reinstall the app and look for a restore option. Backups depend on settings you turned on earlier.
- Ask the other person. Their phone can still store the conversation.
Google states that restoring can take up to 24 hours. Your new phone should use the same Android version as the old one or a later one.
Permanently deleted messages from Trash are gone. Google states that you can't recover them from the Trash folder.
Why should You Stop Using the Card Right Away?
New data can overwrite deleted files. Remove the card from the phone or camera and don't take photos or save anything to it.
PhotoRec documentation gives the same advice. It states that you should not save more pictures or files to the affected memory device.
How do You Recover Photos and Files From an SD Card?
PhotoRec is a free, open source recovery application for Windows and other platforms. Its documentation states that it ignores the file system, never saves data to the card and recognizes more than 480 file extensions.
- Remove the card and put it in a card reader connected to a computer.
- Select Cancel if Windows asks you to format the card. Formatting can overwrite your files.
- Open PhotoRec, select the card and start the scan.
- Save recovered files to a folder on your computer. PhotoRec documentation advises against writing them to the partition they came from.
- Open the recovered files and confirm that photos, videos and documents open correctly.
File names and folders don't come back because the tool rebuilds files from signatures. Sort the results by file type.
How do You Avoid Losing Card Data Again?
- Back up photos. Google lists Google Photos as the backup for photos and videos.
- Switch on backups. Enable your Google backup and your chat app's backup so a future loss is easy to undo.
- Eject the card safely. Don't remove a card while a device is saving to it.
