robot TL;DR:

To recover deleted LINE messages on a supported Samsung Galaxy S25+ without a backup, use Dr.Fone - Data Recovery (Android) on Windows: select Advanced Recovery and LINE, scan, preview conversations and LINE Attachments separately, then save selected discoverable results to a PC. For a brief exchanged after a call, inspect the actual written follow-up rather than treating a call entry as its contents. An already retained recording is a separate source, not a way to recreate unrecorded speech or deleted messages.


Ask AI for a summary

After a LINE call with a podcast guest, you agreed to send three interview questions, leave out one topic and use a particular short introduction. Then the written follow-up vanished from your Galaxy S25+. Remembering that the call happened does not recover the precise questions or the guest's correction. To recover deleted LINE messages on Samsung Galaxy S25+ without a backup, the useful target is that missing written brief and any files shared with it.

Dr.Fone - Data Recovery (Android) gives supported users a way to look for the actual LINE conversation data, preview available records and attachments, and save selected results to a PC. You can compare the material found with any genuinely retained recording or separate brief, keeping the guest's words distinct from your own reconstructed notes.

Before you start

Check the exact Galaxy S25+ conditions

The confirmed Samsung Galaxy S25+ record lists Kernel 6.6.98. No Android-version restriction is listed for this model; retain that Kernel condition rather than inferring support from the Galaxy family name. Note the model and Kernel in Settings > About phone > Software information. These are device conditions, not a guarantee of any particular text or audio result.

Prepare Windows and preserve local data

Advanced Recovery is Windows-only and saves selected discoverable data to a PC, not directly back into LINE. Prepare a USB data cable and a private folder for interview material. Keep LINE installed and avoid clearing storage/cache, resetting the phone or experimenting with bootloader or firmware changes. Use the product's on-screen access instructions; no Root mechanism is assumed here.

Identify the written brief, not just the call

Note the guest, the approximate call date and a distinctive subject from the follow-up. List the missing questions, the later correction and any photo, video sample or brief file separately. If a conversation contains material excluded from publication, keep the recovery folder private and obtain current clarification before using ambiguous wording.

Check retained follow-up text and an existing recording separately

Use this check when you remember a call but are unsure whether the information you need was spoken, written afterward or saved in a separate file.

  1. Step 1 Search the written exchange around the call date

    Open the retained 1-on-1 chat, tap its search icon and search a distinctive subject or phrase. Use the calendar option to inspect the relevant date. Read the actual follow-up and any corrections; a call entry does not contain the written question list.

  2. Step 2 Inspect an already recorded call only where the feature applies

    LINE's current call-recording help limits the feature to Japan, Taiwan and Thailand, both accounts registered to the same country/region, and 1-on-1 calls on supported latest-version devices, excluding Windows/Mac sub devices. If you already used that feature and the recording still exists, open the relevant 1-on-1 chat's top menu > Call recordings and select the existing file. Do not enable recording now expecting it to retrieve a past call.

  3. Step 3 Keep each retained source in its own role

    An existing recording can help you listen to what was actually recorded; a separately retained brief can show the questions in that document. Neither replaces a written correction sent later. Keep Memo is relevant only if that specific recording was actually sent there and remains available; it is not an automatic archive of all your chats.

  • This is inspection of existing material, not recovery of a deleted call recording. This article does not claim that Dr.Fone reconstructs call audio, generates transcripts or supports a dedicated LINE call-recording recovery category.
  • The recording menu is not a universal LINE feature. If it does not apply to your account or no recording was made, continue with retained text checks and the documented LINE app-data scan.

Build the brief from the right kind of record

Source you can inspectUseful contentHow to interpret it
A written question list in LINEThe actual proposed questionsRead the guest's later response before treating the first list as settled.
A later message changing the introduction or topicThe specific revised wording or exclusionKeep enough surrounding text to show which part of the brief it changes.
An existing call recordingOnly the speech that was actually recorded and retainedA later written change may supersede what was said; an unrecorded call cannot be replayed from its entry.
A shared image, video or brief fileThe accessible reference sample or documentA sample is not necessarily the final introduction or permission to publish it.
Your newly written summaryA practical working aid for the next discussionLabel it as your new summary and confirm unresolved points with the guest.

Common problems and fixes

The Call recordings menu is absent

Do not interpret the missing menu as proof that a recording was deleted. The feature has country/region, account and device conditions and only helps with calls that were actually recorded. Search retained follow-up text and any separate brief, then inspect the available LINE scan results for the missing written exchange.

An existing recording opens, but the question correction is not in it

Check whether the change was written after the call. Review LINE conversation results around that time and keep the original questions and the correction together if both are found. Do not attribute your recollection of the change to the recording when it is not actually audible there.

A reference clip is found, but the matching instruction is missing

Save the usable clip and inspect LINE conversations separately for its purpose and any limits on use. A recovered file does not establish a final editorial decision. Request current clarification about the unresolved point rather than assuming an attachment's name or preview supplies the missing message.

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

Dr.Fone - Data Recovery (Android) helps you look for the missing written LINE brief on a supported Galaxy S25+ without relying on an earlier backup. Its Windows-only Advanced Recovery workflow lets you inspect discoverable conversations and available attachments separately, then save the selected records to a PC. That gives you actual material to review alongside your retained sources instead of trying to reconstruct the guest's exact wording from memory.

  • Conversation preview helps identify available proposed questions and written follow-up changes.
  • The separate LINE Attachments view lets you inspect discoverable images, videos and brief files on their own merits.
  • Selective PC saving lets you keep the relevant interview reference privately without collecting unrelated conversations.

Follow the official Advanced Recovery workflow

  1. Step 1 Enter Advanced Recovery and connect the Galaxy S25+

    Start Dr.Fone on Windows and choose Toolbox > Data Recovery > Android > Recover Android Data. Select Advanced Recovery and click Start Scan. Connect the supported Galaxy S25+ by USB when prompted and complete the on-screen device-detection instructions.

    Select Standard Recovery or Advanced Recovery
  2. Step 2 Select LINE for the missing written exchange

    Choose LINE from the available app-data categories and click Start Scan. This directs the workflow toward the written LINE exchange and available reference attachments.

    Select app data types for Advanced Recovery
  3. Step 3 Maintain the connection during scanning

    Keep the phone connected until the scan completes. If stopping is necessary, click Cancel before removing the USB cable. Follow the displayed restart instructions if the phone is temporarily unresponsive after scanning or recovery.

  4. Step 4 Preview the brief and available reference attachments

    Choose LINE to review available conversations and look for the guest's question list and subsequent changes, using search and filters where offered. Open LINE Attachments separately to browse the available photos, videos and files. Select the records that actually answer the missing-brief questions.

    Preview LINE conversations
    Preview LINE attachments
  5. Step 5 Save the selected records to your computer

    Click Recover, choose a folder on your PC and follow the save prompts. Open the saved output and check the wording and usable files. Keep newly written notes and independently retained recordings separate from these results; this mode does not insert a brief back into LINE.

Conclusion

A clear interview brief depends on the words actually exchanged, including the follow-up that changed the first plan. Dr.Fone - Data Recovery (Android) helps you look for discoverable LINE messages, inspect available reference attachments and save selected records privately to your PC. Download Dr.Fone for Windows, connect your supported Samsung Galaxy S25+ and start the guided scan to look for the material you need before preparing the next conversation.

FAQ

  • 1. Can I recover deleted LINE messages on Galaxy S25+ without a backup?
    Dr.Fone - Data Recovery (Android) provides a supported-device scan route without requiring an earlier LINE backup. Use Advanced Recovery on Windows, select LINE, inspect available conversations and LINE Attachments, then save selected results to a PC.
  • 2. Can I turn on LINE call recording now to recover a past call?
    No. Recording is not retroactive. The retained-recording check only applies when the call was actually recorded and that recording remains accessible, under LINE's feature conditions. It does not retrieve unrecorded speech or the written messages sent afterward.
  • 3. Is Call recordings available to every Galaxy S25+ LINE user?
    No. LINE currently limits the feature to Japan, Taiwan and Thailand, accounts registered to the same country/region, supported latest-version devices other than Windows/Mac sub devices, and 1-on-1 calls. These are LINE feature conditions, separate from the phone's Dr.Fone scan conditions.
  • 4. Will the scan produce a transcript or reconstruct a deleted call recording?
    No such capability is claimed in this guide. The documented workflow previews discoverable LINE conversations and available LINE Attachments and saves selected results to a PC. It does not generate speech, a transcript or a missing interview brief from a call entry.
  • 5. Does LINE backup provide another no-backup route for the missing brief?
    No. Standard Backup requires successfully backed-up text from before deletion and is not full media recovery. A newly made backup does not recreate missing messages, and LINE says Premium Backup cannot roll back manually deleted chat history. Preserve current local data while inspecting available sources.
