Two wall-colour photos can look almost identical while the missing LINE message explains that one was taken under a warm lamp and the other in daylight. A familiar image alone may no longer tell you which comparison your partner meant. If you need to recover deleted LINE messages on Google Pixel 6 Pro without a backup, focus on finding the written qualification as well as the pictures.
Dr.Fone - Data Recovery (Android) gives a supported Pixel 6 Pro a device-scan route: preview the conversations found, inspect available photos, videos and files separately, and save the useful records to a Windows PC. Before scanning, one optional check can help if you already used Google Photos partner sharing: an independently saved image can survive changes to the source photo, making it a different reference rather than a live mirror of your partner's library.

Before you start
Match the Pixel 6 Pro entry
The supplied Google Pixel 6 Pro support record lists Android 14 and Kernel 6.1.157. Keep those conditions together for this exact model; the Pixel 6a's additional Kernel entry is not a Pixel 6 Pro condition. Note your phone's displayed Android and Kernel information. If they differ, or Advanced Recovery is unavailable, ask Dr.Fone support to check the configuration without changing firmware.
Keep the original LINE installation intact
Prepare a Windows PC, USB data cable and destination folder. Advanced Recovery is Windows-only and saves selected available results to PC, not back into LINE or a cloud account. Keep LINE installed and signed in; avoid clearing its storage, reinstalling, resetting, flashing or unlocking the bootloader. Follow the product's authorized connection and access prompts rather than a generic Root tutorial.
Separate a photo copy from a LINE backup
Partner sharing is relevant only if an independent photo was already backed up and shared through Google Photos; no new upload or sharing setup is required here. LINE Standard Backup saves text only and is for same-OS restoration with a suitable earlier backup. A Standard backup made after manual chat deletion, or Premium Backup, does not roll back that manually deleted history. None of those backups is required by the device scan.
Check an already-saved partner photo, not just the current shared image
You already receive photos through Google Photos partner sharing and want to identify which visual comparison remains. Skip this check if the images only ever existed inside LINE.
Step 1 Open the existing partner source
In Google Photos on Android, tap your account picture or initial, then Photos settings > Sharing > Partner sharing, and tap your partner's name. Review only material already shared with your account. Do not start a new sharing arrangement, widen the shared selection or access someone else's account to look for the missing discussion.
Step 2 Compare the shared view with your own saved copy
Look in your own Photos view or search results for a photo you previously saved from partner sharing. Google says saved partner photos appear there. If the owner later deletes the source, it disappears from partner sharing, but a copy saved beforehand can remain in your library. Likewise, later edits to the owner's version do not apply to a copy already saved by the partner.
Step 3 Record what each actual image shows
Compare the visible wall area, lighting and any written sample label rather than assuming two images are the same current version. Keep 'my previously saved copy' separate from 'the image now in partner sharing'. The picture may help identify the sample, but it cannot supply an absent LINE sentence saying which lighting condition to use for the comparison.
Step 4 Treat a missing shared image as a source question
Check only the existing sharing scope if the expected image is absent: partner sharing depends on backed-up photos and can use date, people and other-Android-app content selections. Do not turn on additional sharing or backup as a recovery experiment. If no independent copy is available, proceed to the LINE scan for any local conversation and attachment data still discoverable.
- This is retained-photo inspection, not recovery of deleted LINE messages. A photo in your library and a photo still offered by partner sharing are different availability states, not proof of two separate original captures.
- Google warns that photo dates and face grouping can be imperfect. Do not use a date filter or a matching face alone to establish the time, sender or lighting qualification of the missing LINE exchange.
Which colour-comparison information can each source provide?
| What you find | Useful next action | What it actually establishes |
|---|---|---|
| A photo still visible in partner sharing | Inspect the current shared version | A shared visual reference, not the missing LINE instructions. |
| A copy saved before the owner edited or deleted the source | Compare that actual saved image with any current version | An independently retained photo that may differ from today's shared view. |
| No photo in partner sharing | Check existing scope and your already-saved library | Absence from this view does not prove LINE deleted the attachment. |
| Relevant text in the LINE scan | Read the sample name and lighting qualification together | The found wording may explain how the comparison was intended. |
| A useful item in LINE Attachments | Preview it and select the needed photo, video or file | A found attachment can be kept even if the associated explanation is missing. |
Common problems and fixes
The saved photo looks different from the one your partner sees
A previously saved partner copy does not automatically receive the owner's later edits. Compare the actual images without overwriting either source or labelling one as the agreed choice. In the LINE preview, look for the wording that identifies the sample and viewing condition; a crop or colour appearance alone cannot establish that instruction.
The scan finds a photo but not the lighting explanation
Review LINE conversations separately from LINE Attachments and use search or filters where offered. Keep a useful found picture as a visual reference, while leaving its missing qualification unresolved. If you need a decision now, ask for a fresh clarification and label it as new guidance rather than a recovered old message.
How to use Dr.Fone - Data Recovery (Android)
Dr.Fone - Data Recovery (Android) helps you look beyond a surviving picture for the missing LINE context on a supported Google Pixel 6 Pro. Its Windows-only Advanced Recovery mode scans LINE app data without an existing backup, separates conversation previews from attachment results, and saves selected discoverable items to PC. You can concentrate on the actual sample wording, compare the photos or clips found, and keep a focused reference instead of exporting every unrelated result.
- LINE conversation preview helps locate an actual qualification rather than guessing it from the image.
- Separate LINE Attachments review lets you inspect available photos, videos and files on their own merits.
- Selective PC recovery keeps the useful text and visual references together outside the phone.
Scan Android phones and tablets directly.- Preview and recover only what you want.
- Supports WhatsApp, photos, videos, contacts, and more.
- Works with 6000+ Android devices.
Follow the official Advanced Recovery workflow
Step 1 Connect the Pixel 6 Pro through Advanced Recovery
Launch Dr.Fone on Windows and open Toolbox > Data Recovery. Select Android > Recover Android Data, choose Advanced Recovery and click Start Scan. When prompted, connect the supported Pixel 6 Pro with a USB data cable and follow the on-screen instructions until the phone is detected.
Step 2 Select LINE as the app to scan
Choose LINE from the available app-data categories and click Start Scan. WhatsApp and WhatsApp Business each require a separate scan from the other categories; neither is needed for this LINE recovery task.
Step 3 Keep the phone connected during scanning
Let Advanced Recovery scan the selected data with the phone connected. If you must stop, click Cancel before removing the cable. If the phone is temporarily unresponsive after scanning or recovery, follow the restart instructions displayed by the product.
Step 4 Preview the explanation and colour-reference files
Choose LINE in the results sidebar and inspect the relevant conversation for the sample name and lighting instruction. Use search and filters where available. Open LINE Attachments separately to review found photos, videos and files, then select the actual results that help explain the comparison.
Step 5 Recover selected LINE records to your computer
Click Recover and follow the prompts to choose a computer folder. Save the selected results and open the output to check the text and files you chose. These are PC copies; the workflow does not repopulate the LINE thread or update a Google Photos library.
Conclusion
For a supported Google Pixel 6 Pro, Dr.Fone - Data Recovery (Android) offers a practical way to look for the LINE explanation a surviving image cannot replace. Preview available conversations, inspect the relevant photos and other attachments, and save the useful records selectively to your PC. Download Dr.Fone for Windows and start Advanced Recovery to bring the written context and visual references into one useful recovery review.
FAQ
1. Can I recover deleted LINE messages on Google Pixel 6 Pro without a backup?
Dr.Fone - Data Recovery (Android) offers a local scan on the supported Pixel 6 Pro entry: Android 14 with Kernel 6.1.157. Use Advanced Recovery on Windows, scan LINE, preview what is found and save selected discoverable results to PC. An earlier LINE backup or Google Photos sharing arrangement is not required.2. Why can a partner photo survive after its owner deletes it?
Google Photos distinguishes the source shared photo from a copy the partner already saved. The source disappears from partner sharing when deleted, but a copy saved beforehand can remain in the recipient's library. That is an independent retained image, not recovery of the original LINE attachment or conversation.3. Will the scan restore expired LINE originals from Google Photos?
No. This workflow scans supported local LINE data, not an inaccessible cloud photo or an expired server original. A photo already accessible in your Google Photos account is a separate source. In the scan, select only the conversation and attachment data actually available in the results.4. Can a new LINE backup undo the deletion instead?
A new Standard Backup made after manual chat deletion cannot bring back the deleted history, and Premium Backup does not provide that rollback either. Standard Backup is text-only and same-OS, with a suitable backup from before deletion needed for native restoration. The no-backup scan saves found data to PC rather than performing that native restore.
