robot TL;DR:

Dr.Fone - Data Recovery (Android) provides a no-backup device-scan route for deleted WhatsApp messages on eligible Samsung Galaxy S25 Ultra configurations. After confirming your exact software configuration, use Advanced Recovery on Windows to connect the phone, select WhatsApp, scan and preview conversations and attachments, then save selected results to a PC. It can help you look for the discussion as well as shared photos and videos; the recoverable items depend on what the scan finds.


Ask AI for a summary

You finish a trip, tidy up WhatsApp and accidentally delete the group that held everyone's photos, short videos and the details of the next family gathering. A few pictures may already be in your gallery, but the conversation that explains them is gone. To recover deleted WhatsApp messages on a Samsung Galaxy S25 Ultra without a backup, it helps to look for the chat and its shared media together.

Dr.Fone - Data Recovery (Android) offers that focused approach for eligible devices. Its Windows-only Advanced Recovery workflow scans WhatsApp app data, lets you inspect the conversations and attachments found, and saves your chosen records to a PC. You can concentrate on the missing memories and useful messages rather than saving a large collection of unrelated phone files.

Before you start

Confirm the S25 Ultra configuration before starting

Record the model number, Android version and full build under Settings > About phone and Software information. The supplied S25 Ultra Root reference names SM-S9380 and SM-S938N, kernel 6.6.98, and several builds including S9380ZCSCCZG1 and S938NKSUACZF1. Android is not specified. These are configuration references, not proof that every listed identifier can be combined or that every regional S25 Ultra is supported. The public Advanced Recovery guide covers Android 9-13; ask Dr.Fone support to confirm your complete configuration and app version before using an additional Root-based route.

Prepare Windows without changing the phone's data

Have a Windows PC, a reliable USB data cable and enough space for the photos, videos and other results you want to save. Keep the existing WhatsApp installation intact. Do not clear its storage, factory-reset the phone, unlock its bootloader or flash firmware as a recovery experiment. Follow the product's supported connection and access prompts rather than assuming Advanced Recovery is root-free or that Root is lossless.

Make a short list of the memories and messages you need

Note the group name, the people involved and an approximate date range. Separate the missing conversation from photos or videos that you can already open elsewhere. Advanced Recovery saves selected available results to your computer; it does not put the recovered thread back into WhatsApp.

Check for surviving WhatsApp photos and the original group

A trip or family chat can leave more than one useful copy of a photo. This check helps you keep accessible media while deciding which deleted messages and attachments still need a scan.

  1. Step 1 Search the group and look in Archived

    Search WhatsApp for the group name or one of its participants, and check Archived if the conversation disappeared from the main list. Open a matching conversation to see whether the missing exchange is still there. A retained archived chat can be read without deleted-data recovery.

  2. Step 2 Open the media you already have

    Check your gallery or an existing folder where you previously saved WhatsApp photos and videos. Open the full file rather than relying on a small thumbnail. Keep any usable copies, then list the missing clips, images and accompanying messages to look for in Dr.Fone.

  • A gallery copy may give you the picture without the original message or its context. It is not a restored WhatsApp conversation.
  • If the chat was genuinely deleted, the device-scan workflow below does not depend on having a Google Drive backup.

Common problems and fixes

You can see a photo in the gallery but cannot find its chat

Keep the usable image and continue reviewing WhatsApp conversation results for the group or contact. A separately saved photo and the deleted message are different recovery targets; one being available does not establish that the other will be found.

A scan contains many similar holiday images

Start with the relevant conversation if it is available, then inspect the photo and video categories. Use the search or filters shown in the results view to narrow your selection. Preview the actual item before saving, especially when several images depict the same event.

Your regional S25 Ultra is not recognized for Advanced Recovery

Check that you are using Windows and give Dr.Fone support the full model suffix, current Android version, build and app version. A reference for SM-S9380 is not a reason to change an SM-S938N or another regional phone's firmware.

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

Dr.Fone - Data Recovery (Android) helps you look for the parts of a deleted WhatsApp conversation that matter: the message with the plan, the shared photo or the video you meant to keep. On an eligible Galaxy S25 Ultra, its Windows-only Advanced Recovery mode scans selected WhatsApp app data without requiring an existing backup, presents available conversations and attachment categories for preview, and saves your selected results to a PC. That gives you a practical way to recover useful records without collecting every unrelated file.

  • Keep context in view: inspect available conversation results alongside the media you are trying to identify.
  • Find more than message text: review found WhatsApp photos, videos, audio and other attachments in their respective categories.
  • Choose the memories worth keeping: preview results and save a focused PC copy of the records you select.

Follow the official Advanced Recovery workflow

  1. Step 1 Open Advanced Recovery and connect the S25 Ultra

    Launch Dr.Fone on Windows and choose Toolbox > Data Recovery. Select Android > Recover Android Data, choose Advanced Recovery and click Start Scan. Connect your eligible Galaxy S25 Ultra by USB when prompted and follow the on-screen device-detection instructions.

    Select Standard Recovery or Advanced Recovery
  2. Step 2 Select personal WhatsApp data

    Choose WhatsApp and click Start Scan. Select it separately from WhatsApp Business and the other data categories, as required by the guide, so the scan targets the personal chats and shared media you need.

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

    Leave the S25 Ultra connected while Advanced Recovery scans. If you need to stop, click Cancel before disconnecting the USB cable. If the phone is temporarily unresponsive afterward, follow the restart instructions displayed by the product.

    Scan Android app data with Advanced Recovery
  4. Step 4 Preview the group conversation and media results

    Browse available WhatsApp conversations and open the relevant group or contact. Use search and filters where available, then inspect the photo, video, audio and other attachment categories. Select the found messages and files that match your recovery list.

    Preview WhatsApp conversations and attachments
  5. Step 5 Save selected messages and attachments to your PC

    Click Recover and follow the prompts to choose a computer folder. Complete the save, then open the output to review the selected records. This creates a PC copy rather than importing a conversation into WhatsApp on the S25 Ultra.

Conclusion

For a deleted group chat that held both memories and practical details, Dr.Fone - Data Recovery (Android) brings a useful combination of WhatsApp-focused scanning, conversation and media previews, and selective saving to your PC. Download Dr.Fone for Windows, confirm your Galaxy S25 Ultra configuration and start the guided workflow to look for the messages, photos and videos you want back.

FAQ

  • 1. Can I recover deleted WhatsApp messages on Samsung Galaxy S25 Ultra without a backup?
    For an eligible configuration, Dr.Fone - Data Recovery (Android) offers an Advanced Recovery device scan that does not require an existing backup. Connect the phone to Windows, scan WhatsApp, preview available results and select records to save to a PC. Recovery depends on the data found during the scan.
  • 2. Does the S25 Ultra Root reference prove support for my Android version?
    No. The supplied record does not state Android and is not a complete regional or firmware compatibility matrix. The public Advanced Recovery guide covers Android 9-13. Confirm the full model, current Android version, build and app version with Dr.Fone support for the applicable route.
  • 3. Can I recover deleted WhatsApp photos and videos as well as messages?
    On an eligible device, inspect the WhatsApp photo and video results as well as the conversation view. You can save the available media you select, even if your main goal is one clip or image rather than the whole discussion.
  • 4. Will recovering the files recreate my WhatsApp group chat?
    No. This Advanced Recovery workflow saves selected results to your PC. A recovered message or attachment is a separate copy for review, not a restored group thread inside WhatsApp.
  • 5. Is a photo in my gallery evidence that the deleted message is recoverable?
    No. A gallery file may be an independently saved copy. Keep it if it opens, then review the scan's conversation results separately for the message text and context you need.
