A family LINE conversation can hold more than photos: the names behind them, the date of a celebration and the messages you wanted to keep. Delete that conversation on your Galaxy S24 Ultra, and a few images in an album may be all you can still find. If you need to recover deleted LINE messages on Samsung Galaxy S24 Ultra without a backup, Dr.Fone - Data Recovery (Android) provides a device-scan route for looking for the missing conversation and its attachments.
The useful goal is to recover what matters, not simply collect every image on the phone. Advanced Recovery lets you review found LINE conversations separately from shared media and save chosen results to a PC. Start by identifying what is still available in LINE, then use the five-step Windows workflow to look for deleted local data.

Before you start
Keep the Galaxy S24 Ultra support conditions together
The support entry for Samsung Galaxy S24 Ultra lists kernel versions 6.1.128 and 6.1.145; no Android-version restriction is listed for this model. Check the phone identity under Settings > About phone and its software details under Software information, retaining the listed kernel condition. This entry is for the S24 Ultra, not a blanket claim for every S24-family phone.
Preserve the current phone and prepare Windows
Use a Windows PC, a USB data cable and a folder for the recovered output. Advanced Recovery is Windows-only. Keep LINE installed, avoid clearing its storage or resetting the phone, and follow the product's displayed access instructions. Do not unlock the bootloader, flash firmware or follow an unrelated Root tutorial as a recovery shortcut.
Separate a missing backup from missing media
LINE's built-in restoration needs an applicable earlier backup. Standard Backup on Android saves text history to Google Drive, not the photos and videos shared in a chat. A backup made after deletion cannot supply the deleted exchange, and Premium Backup is not a historical deletion rollback. The device scan below does not require that earlier backup; it can save only data it finds, to a PC rather than back into LINE.
Check hidden chats before treating the conversation as deleted
A whole family or group conversation has disappeared, but you are not sure whether you tapped Hide or Delete.
Step 1 Open LINE's actual hidden-chat list
In LINE, go to Home > Settings > Chats > Hidden chats. If the missing conversation appears there, tap Edit > Unhide chat.
Step 2 Check for the old exchange, not just the chat name
Open the conversation and look for the messages from the event. A hidden chat retains its history. A deleted chat can reappear when a new message arrives, but that does not bring its previous messages back.
- Unhiding is a way to access existing history. If the target messages are truly deleted, continue to the device scan.
Look for family photos that were already saved in LINE albums
You want the celebration photos as well as the surrounding messages, and someone had added pictures to an album before the chat disappeared.
Step 1 Inspect an existing album from the relevant chat
Open an album you can still access for that friend or group and inspect the photos inside it. LINE's All albums view can also include albums from hidden or deleted chats when its membership and display conditions are met. For users in Japan, Taiwan and Thailand, the official route is Chats > Friends > Your albums under Your albums with friends.
Step 2 Keep the accessible images and identify the remaining gaps
Use the album's save option for the items you can actually open. Note which photos, videos or message details are still missing so you can look for those in the scan. Album availability and navigation can vary by region; an empty album view is not proof that no local attachment data exists.
- An album copy is separate from the deleted conversation. Finding it does not restore the chat or establish that the original-quality image is available.
- Do not buy or activate Premium Backup expecting it to reverse an earlier chat deletion.
What each LINE result gives you on Galaxy S24 Ultra
| What you find | Useful next action | What it means |
|---|---|---|
| Old messages in Hidden chats | Unhide the conversation and read the exchange. | The history was retained, not recovered from deletion. |
| Photos in an accessible album | Save the available pictures and list any missing items. | You have album copies, not necessarily the deleted chat or original files. |
| Conversation results under LINE in Dr.Fone | Preview the relevant exchange and select useful records. | These are available phone-scan results; review the actual content before saving. |
| Photos, videos or files under LINE Attachments | Preview and select the media you need separately. | Attachments can be found independently of complete message text; selected output goes to PC. |
Common problems and fixes
The family album is visible, but the conversation is empty
Keep the accessible album photos, then review LINE conversation results in Dr.Fone for the missing text. Albums and chat history are different stores of information, so an album alone cannot establish that the deleted messages remain available.
A photo result is present, but it is not the original you need
Inspect the available preview and saved file rather than assuming a thumbnail represents a recoverable full-resolution original. You can also ask the sender for an original they still hold. Neither an expired LINE download nor a partial scan result guarantees the original file exists locally.
Advanced Recovery is not offered after connecting the phone
Make sure you are using the Windows workflow and that the phone is identified as Galaxy S24 Ultra. Compare the kernel with the listed 6.1.128 or 6.1.145 condition and read the product's eligibility message. If it blocks scanning, contact Dr.Fone support with that message rather than changing the firmware.
How to use Dr.Fone - Data Recovery (Android)
Dr.Fone - Data Recovery (Android) gives you a focused way to look beyond the family photos that happen to remain in an album. On a supported Galaxy S24 Ultra, its Windows-only Advanced Recovery mode scans LINE app data without an existing backup, separates conversation previews from LINE Attachments and saves your selected available results to a PC. That helps you look for both the messages that explain an occasion and the media shared around it.
- Conversation-first review helps you locate meaningful text instead of treating every image as a complete recovery.
- A separate LINE Attachments view lets you examine found photos, videos and files alongside the chat search.
- Selective PC saving lets you keep the relevant family records without exporting every available result.
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 Open Advanced Recovery and connect the S24 Ultra
Launch Dr.Fone on Windows and open Toolbox > Data Recovery. Choose Android > Recover Android Data, select Advanced Recovery and click Start Scan. Connect your Galaxy S24 Ultra by USB when prompted and follow the displayed instructions until the phone is detected.
Step 2 Choose LINE app data
Select LINE from the available app-data categories and click Start Scan. This is the app-data scan for the missing LINE conversation, rather than a backup restoration or a general search of the phone's gallery.
Step 3 Keep the phone connected during scanning
Leave the USB connection in place while Advanced Recovery scans. If you need to stop, click Cancel before unplugging the cable. If the phone is temporarily unresponsive afterward, follow the on-screen restart instructions.
Step 4 Preview the conversation and its attachments separately
Choose LINE in the results sidebar to inspect available conversations. Use search or filters where available to locate the family exchange. Then open LINE Attachments to review found photos, videos and files, selecting the items you want to keep.
Step 5 Save selected LINE records to your computer
Click Recover and follow the prompts to choose a folder on your PC. Save the selected results, then open the output to check the messages and media you recovered. This produces a computer copy; it does not refill the LINE conversation on the S24 Ultra.
Conclusion
For a lost family conversation on Samsung Galaxy S24 Ultra, Dr.Fone - Data Recovery (Android) brings the important pieces into a manageable recovery process: preview available messages, inspect shared media separately and save the records you choose to your PC. Download Dr.Fone for Windows, connect your supported S24 Ultra and start looking for the LINE messages and memories you want to keep.
FAQ
1. Can I recover deleted LINE messages on Samsung Galaxy S24 Ultra without a backup?
Dr.Fone - Data Recovery (Android) offers a device-scan route for supported S24 Ultra configurations. It does not need an existing LINE backup: use Advanced Recovery on Windows, inspect the available LINE and LINE Attachments results and save selected items to PC. Recovery depends on the data the scan finds, not just the phone appearing on a support list.2. Does finding an album mean the deleted chat is restored?
No. LINE can display existing albums from eligible hidden or deleted chats in All albums. Those album photos are retained content. To look for deleted message text, review the LINE conversation results separately.3. Will Standard Backup bring back my LINE photos and videos?
Standard Backup saves text chat history, not chat photos and videos. An applicable pre-deletion text backup is a different route from this no-backup scan. Check existing album or sender copies for media and use LINE Attachments to inspect media found by Dr.Fone.4. Can I recover expired original LINE photos?
Only if an accessible copy remains or the scan finds usable local data. An expired download link does not prove that the original survives on the phone. Preview the actual result and check the saved file; request the sender's retained original when available.5. Does this put recovered messages back into LINE?
No. Advanced Recovery saves the selected available records to a folder on your Windows PC. You can review that separate copy outside LINE.
