robot TL;DR:

To recover deleted WhatsApp messages on an eligible Samsung Galaxy S25 without a backup, use Dr.Fone - Data Recovery (Android) and its Windows-only Advanced Recovery workflow. Confirm your exact device configuration, connect the phone, scan WhatsApp, review the available conversation and attachment results, and save selected records to a PC. You can focus on the message, photo or document you need rather than recovering every result; this process does not import the saved records into WhatsApp.


Ask AI for a summary

The pickup address, a booking reference or a carefully explained set of instructions can disappear with one deleted WhatsApp conversation. If you need that information today, searching for a backup you never made is frustrating. Recovering deleted WhatsApp messages on a Samsung Galaxy S25 without a backup starts with identifying the exchange you need and choosing a device-scan route.

Dr.Fone - Data Recovery (Android) helps eligible Galaxy S25 users look for those missing records. The Windows-only Advanced Recovery process presents found WhatsApp conversations and attachments for review, so you can select the useful messages and files and keep a copy on your PC. This guide puts a specific information-retrieval goal first: locate the right exchange, check what is available and save what helps.

Before you start

Check the regular Galaxy S25, not a different S25 variant

Open About phone and Software information to note your model number, current Android version and full build. The supplied Galaxy S25 Root reference names SM-S9310, kernel 6.6.98 and build S9310ZCSCCZG1. It does not specify Android and does not establish support for other regional models, S25+ or S25 Ultra. Public Advanced Recovery guidance covers Android 9-13. For the additional Root route, confirm the full configuration and installed WhatsApp version with Dr.Fone support rather than inferring compatibility from the S25 name.

Keep the original app data available

Use a Windows computer and a reliable USB data cable, with a destination folder ready for recovered records. Do not reinstall WhatsApp, clear its storage, reset the phone or change firmware to imitate a reference configuration. Root requirements and their risks need confirmation for the applicable route; this guide does not prescribe bootloader unlocking or promise a root-free or lossless procedure.

Identify the actual conversation and output you need

Write down the person's name, group name, an approximate date and a distinctive phrase you remember. Confirm that the exchange was in personal WhatsApp rather than WhatsApp Business, which uses a separate scan selection. The result here is a copy saved to your PC, not the recreation of the original conversation in the phone's chat list.

Locate an accessible copy of the specific WhatsApp information

When one address, booking detail or shared file is the urgent priority, a surviving copy can solve the immediate problem while the product workflow addresses genuinely deleted records.

  1. Step 1 Search the contact and inspect the conversation

    Search personal WhatsApp for the contact or group and check Archived if the thread is absent from the main list. If the conversation opens, look for the actual message you need, not just the presence of the contact. A remaining chat can still be missing a deleted exchange.

  2. Step 2 Request the detail again if a participant still has it

    If appropriate, ask the sender to resend the particular address, instruction or file from their own surviving copy. This can recover the information for immediate use. If you need the earlier discussion as well, or the participant cannot supply it, continue with the eligible Galaxy S25 device scan below.

  • Reading an archived chat or receiving a resent detail is not recovery of deleted data from the phone.
  • The Advanced Recovery route in this article scans the device and does not require an existing Google Drive backup.

Common problems and fixes

You see the contact name, but not the missing instruction

Open the found conversation and inspect its contents. Use a remembered phrase with the search options where available, and review relevant attachments separately. Do not treat the contact's appearance as proof that the full history was recovered.

You accidentally chose WhatsApp Business

Use the personal WhatsApp category for this guide. WhatsApp and WhatsApp Business have separate scan selections and result views; they cannot be scanned together with the other categories in the documented Advanced Recovery selection.

Your S25 build differs from S9310ZCSCCZG1

Send the actual model number, current Android version, build and app version to Dr.Fone support for an eligibility check. Keep the existing phone configuration intact rather than downgrading or flashing it to match the supplied reference.

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

Dr.Fone - Data Recovery (Android) gives you a focused way to search for a deleted WhatsApp exchange on an eligible Galaxy S25. Its Windows-only Advanced Recovery mode scans selected WhatsApp app data, lets you preview the available message and attachment results, and saves your chosen records to a PC without relying on a backup. The benefit is control: look for the information you need, verify the found content and keep a useful recovery copy instead of selecting everything.

  • Target the right app: a separate personal WhatsApp scan keeps the recovery task relevant to this conversation.
  • Verify the content: inspect found conversations and their available photo, video, audio or document results.
  • Save only useful records: selective PC recovery suits a missing instruction or attachment as well as a broader chat-recovery need.

Download Dr.Fone for Windows, confirm your Galaxy S25 configuration and start looking for the records that will help you move forward.

FAQ

  • 1. How can I recover deleted WhatsApp messages on Galaxy S25 without a backup?
    For an eligible Galaxy S25 configuration, use Dr.Fone - Data Recovery (Android) on Windows and select Advanced Recovery. Scan personal WhatsApp, inspect the available conversations and attachments, then save selected results to a PC. An existing backup is not required for this device-scan route.
  • 2. Does finding my contact mean the whole conversation was recovered?
    No. Open the conversation preview and check for the specific exchange you need. A contact, a message and an attachment are different results; only the records actually available in the scan can be selected for recovery.
  • 3. Can I recover deleted WhatsApp photos, videos and attachments on Galaxy S25?
    On an eligible device, the WhatsApp results include conversation and attachment categories for inspection. Look for the relevant image, clip, audio item or document, preview what is available and select the useful records to save.
  • 4. Does the SM-S9310 reference cover every Galaxy S25?
    No. The supplied record lists a particular model, kernel and build but does not state Android. Public Advanced Recovery guidance covers Android 9-13; newer or different configurations need confirmation for their own recovery route.
  • 5. Can I read the recovered records on the phone as the original chat?
    The documented Advanced Recovery process saves the selected records to your PC. It does not insert them into WhatsApp on the Galaxy S25 or recreate the original chat history.
