robot TL;DR:

To look for deleted LINE messages on Samsung Galaxy Z Flip 5 without a backup, use Dr.Fone - Data Recovery (Android) on Windows, choose Advanced Recovery and LINE, and scan the connected phone. Preview LINE conversations and LINE Attachments separately, then save the useful records found to your PC. An existing chat screenshot can preserve an excerpt, but it does not restore messages outside the captured range.


Ask AI for a summary

A screenshot of a radio-show cue list may show the song titles but omit the message explaining which recording to use or where a transition should begin. If you deleted the LINE discussion on your Samsung Galaxy Z Flip 5, the missing sentence can matter more than the image you kept. Recovering useful context means looking for the actual exchange, not guessing from a cropped excerpt.

Dr.Fone - Data Recovery (Android) gives you a no-backup device-scan route for finding available LINE messages and shared files. You can preview the discussion, inspect attachments separately and save only the relevant cue notes, reference images or clips to a PC. First establish what your surviving capture includes, then use the five-step Windows workflow to look for the missing material.

Before you start

Check the exact Galaxy Z Flip 5 support record

The confirmed Samsung Galaxy Z Flip 5 record lists Kernel 5.15. No Android-version restriction is listed for this named model. Note the model, Android version and Kernel under the phone's About phone and Software information screens; keep the listed Kernel condition rather than assuming another Flip model has identical support.

Prepare Windows and preserve the phone's remaining data

Advanced Recovery is Windows-only. Have a reliable USB data cable and a private PC destination folder ready. Keep LINE installed and avoid clearing its storage, resetting the phone or following an unrelated rooting, unlocking or flashing tutorial. Follow the product's actual access prompts; this guide does not prescribe an unverified Root procedure. Only records still discoverable by the scan can be saved, and the output is a PC copy rather than an import into LINE.

Define the missing cue, not just the missing chat

Write down the show date, track title, recording version and the kind of note you need: transition timing, a spoken introduction or a later exception. Keep any existing screenshot unchanged. Its selected message range and possibly hidden names are important context for comparing it with conversation results.

Check what an existing LINE capture actually preserved

Use this check when you have a saved or voluntarily shared screenshot but still lack the original cue wording. It helps you recover useful information already retained without treating an image as a full chat archive.

  1. Step 1 Read both ends of the captured exchange

    Open the saved image and identify its first and last visible messages. Look for an unfinished reply, a reference to a later change or a cue that continues beyond the image. LINE's Capture feature selects a message range, so a clear screenshot may still leave out the sentence you need.

  2. Step 2 Preserve a fuller range only if the messages still exist

    On the Android main device, tap and hold the first retained message, tap Capture, select the last relevant message and tap Capture again. Reselect lets you change the range. Use the download icon to save the resulting image privately; you do not have to forward it. Include any available qualifying or replacement messages rather than only the cue-list image.

  3. Step 3 Respect intentionally hidden participant details

    LINE's Hide info option can hide friends' display names and profile photos in a capture. If an existing image uses that option, do not infer who wrote each cue from the replacement appearance. Ask an appropriate participant for the needed text or review your own available conversation records. A scan is not a way to reverse image anonymization.

  • Creating a new capture works only with messages you can currently open. It cannot extend an old image into deleted messages.
  • An existing Album, Note or deliberately populated Keep Memo may hold a separate reference. Check it only if you actually used it; none is an automatic copy of the deleted discussion.

Turn LINE recovery results into a usable cue reference

What you findUseful information to keepHow to interpret it
A retained chat captureThe visible track names and complete sentences within its rangeA selected excerpt; omitted messages and hidden names are not recoverable from the image itself.
LINE conversation resultsThe named recording, transition instruction and any available follow-up exceptionRead the actual wording rather than assuming the first proposal was the final cue.
LINE Attachments resultsA relevant cue-sheet photo, reference clip or document that can be inspectedMatch its visible contents to the discussion; a filename alone does not establish the chosen recording.
A participant's new explanationA clearly labeled current clarificationUseful for preparing a show, but separate from the historical messages you recovered.

Common problems and fixes

The screenshot looks complete, but the transition still makes no sense

Check whether a reply refers to an earlier recording or a later replacement outside the captured range. In the scan preview, look for the track and adjacent available discussion. Keep the recovered wording alongside the original capture so you can compare the excerpt with its context without altering either source.

A useful clip appears, but its cue message does not

Save the available usable clip if it matters, then review LINE rather than remaining in LINE Attachments. Text and media results can differ. If the cue is absent, mark it as unresolved and request a current clarification instead of assigning a transition based on the clip's duration.

The connected phone is not ready to scan

Use the Windows installation, a working USB data cable and the displayed connection instructions. Compare the exact Z Flip 5 record and Kernel 5.15 with the phone. If the product reports an access or compatibility problem, retain the exact message for Dr.Fone support rather than changing the firmware.

How to use Dr.Fone - Data Recovery (Android)

Dr.Fone - Data Recovery (Android) helps you look beyond a surviving screenshot for the LINE conversation and supporting media still available on your Galaxy Z Flip 5. Its Windows-only Advanced Recovery mode scans app data without requiring an earlier chat backup. Separate previews help you identify the actual cue wording and relevant files, then selectively save those results to a PC for a focused reference.

  • Find context as well as an image: inspect available LINE conversation records for the recording choice or transition explanation.
  • Review supporting material separately: use LINE Attachments to look for relevant photos, videos and files found by the scan.
  • Keep a manageable PC copy: select useful records instead of saving unrelated private conversations.

Follow the official Advanced Recovery workflow

  1. Step 1 Open Advanced Recovery and connect the Z Flip 5

    Launch Dr.Fone on Windows and go to Toolbox > Data Recovery. Select Android > Recover Android Data, choose Advanced Recovery and click Start Scan. Connect the Galaxy Z Flip 5 with a USB cable when prompted and follow the on-screen instructions until the phone is detected.

    Select Standard Recovery or Advanced Recovery
  2. Step 2 Select LINE data

    Choose LINE from the available app-data categories and click Start Scan. This selects the app containing the missing cue discussion and its related attachment results.

    Select app data types for Advanced Recovery
  3. Step 3 Keep the phone connected during the scan

    Let Advanced Recovery scan the selected data while the USB connection remains stable. If you need to stop, click Cancel before disconnecting. If the phone is temporarily unresponsive after scanning or recovery, restart it as instructed on screen.

  4. Step 4 Preview cue wording and LINE Attachments

    Open LINE in the results sidebar to inspect the available conversations. Use search or filters where provided to find the show or track discussion, and read the complete available cue and follow-up. Then open LINE Attachments to review relevant images, videos and files separately. Select the records you want; this attachment view is not a dedicated scan of Note or Album databases.

  5. Step 5 Recover the selected reference to your PC

    Click Recover and follow the prompts to choose a folder on your computer. Save the selected data, then open the output to check the cue text and usable files. Advanced Recovery saves to a PC; it does not return the exchange to the LINE chat list.

Conclusion

For a cue list that needs more than a partial screenshot, Dr.Fone - Data Recovery (Android) offers a practical way to look for missing LINE context, preview supporting media and save selected records together on your PC. Download the Windows version, connect your supported Samsung Galaxy Z Flip 5 and start building a useful reference from the conversations and attachments the scan finds.

FAQ

  • 1. Can I recover deleted LINE messages on Samsung Galaxy Z Flip 5 without a backup?
    Dr.Fone - Data Recovery (Android) provides a Windows device-scan route for the supported model and listed Kernel condition. It does not need an earlier backup, but the recoverable messages depend on what remains discoverable. Preview LINE and save the selected results to your PC.
  • 2. Can Capture or Hide info recover an omitted message or reveal a hidden name?
    No. Capture creates an image of selected existing messages, and Hide info can conceal friends' names and profile photos in that image. Neither restores messages outside its range. Review available original conversation records for context, without treating recovery as de-anonymization of a shared screenshot.
  • 3. Can I also recover deleted LINE photos, videos or cue-sheet files?
    Inspect LINE Attachments after the scan and select relevant usable items that were found. A visible image or filename does not guarantee every original file is available. Preview the actual content before deciding which references to save.
  • 4. Would Standard Backup or Premium Backup bring back this deleted chat now?
    LINE's official restoration needs appropriate previously backed-up data. Standard Backup covers text, not the complete media collection, and a backup made after deletion cannot restore the removed chat. Premium Backup is not a rollback for a manually deleted conversation. This article uses local scanning rather than an unavailable earlier backup.
  • 5. Can I use a linked PC as the untouched original conversation?
    Do not assume the same LINE account on a PC is an independent complete backup. A separately saved screenshot or file may still be useful, but the Advanced Recovery outcome here is selected data saved to a Windows folder, not a restored synchronized chat.
