robot TL;DR:

To recover deleted LINE messages on Vivo T4 without a backup, use Dr.Fone - Data Recovery (Android) on Windows to scan supported local app data, preview LINE conversations and LINE Attachments separately, and save selected results to PC. No Android-version restriction is listed for this named model; its listed Kernel is 6.1.145. If the membership was purchased through Google Play, its existing subscription record can provide a current billing reference while you look for the actual LINE reply about cancellation, a pause or a refund.


Ask AI for a summary

The membership app still opens, but the LINE reply about ending your plan has disappeared from your Vivo T4. Did the provider discuss a pause, stopping the next renewal or a refund for an earlier charge? Continued access cannot answer that on its own: a cancelled Google Play subscription can remain usable for the time already paid. You need the actual reply and the right billing reference, not a guess based on whether the app opens.

Dr.Fone - Data Recovery (Android) gives you a focused way to look for that exchange without a previous LINE backup. Its Windows-only Advanced Recovery workflow lets you read the conversations found on a supported phone, inspect available receipt photos, videos and files separately, and save useful selections to PC. If this particular membership was billed through Google Play, the optional check below helps you understand the plan before reviewing the missing words.

Before you start

Match the Vivo T4 support entry

The approved Vivo T4 record lists Kernel 6.1.145, with no Android-version restriction for this named model. Keep the model and Kernel conditions together; this is not support for every Vivo phone. Note your current model, Android and Kernel information for the product's compatibility prompts without changing firmware to match a record.

Keep the original LINE installation and storage

Prepare a Windows PC, a USB data cable and a writable computer folder. Leave LINE installed and logged in as it already is. Do not clear storage, reinstall, log out, reset the phone or unlock the bootloader as a recovery experiment. Follow Dr.Fone's displayed connection and access directions; an unverified Root procedure is not a preparation step.

Identify the plan and the missing reply separately

Note the contact, approximate exchange date and membership you need to identify. Use the optional Play check only for a subscription actually purchased there and an account you already own and can access. The subscription app's login email may differ from the Google Account used to pay. No billing record or earlier chat backup is needed for the local LINE scan, which saves selected discoverable results to PC rather than into LINE or a provider account.

Optionally inspect the existing Google Play plan without changing it

Use this for a membership actually billed through Google Play. It reads a current billing source, not a retained email, a LINE backup or a historical record of every provider promise. Skip it for memberships bought elsewhere.

  1. Step 1 Open the correct subscription on a computer

    Open play.google.com/store/account/subscriptions in a computer browser and use the Google Account that owns the purchase. Inspect the matching record and, where Manage is offered, click it to read the plan details. If it is not offered, use only the information already displayed. Do not click Cancel subscription, Pause payments, Resume, Resubscribe or a plan-change confirmation as a recovery test. You do not need to change any account on the recovery phone.

  2. Step 2 Read the actual plan type and billing details

    Inspect whether the existing record is a recurring subscription or a prepaid plan, and read any renewal date actually provided. Google says prepaid plans expire at the end of their limited billing period without needing cancellation. A payment plan has a separate distinction: stopping its future auto-renewal does not cancel the remaining payments already committed for the current plan. Do not apply a recurring-plan assumption to every membership.

  3. Step 3 Compare the billing reference with the missing communication

    For a cancelled subscription, Google says access continues for the time already paid, so continued use is not proof that cancellation failed. Keep the current plan details distinct from the historical LINE request and reply. Review the scan for what the provider actually said about the requested date, a pause or a refund; the subscription screen does not recreate that conversation or determine a disputed refund.

  • If the plan is absent, check the purchase account you already know rather than cancelling another plan, adding accounts to the phone or treating an empty list as proof that no purchase occurred.
  • This is an optional read-only check of your own existing billing record. It does not retrieve deleted LINE messages, change a subscription or make Dr.Fone a billing or refund service.

Available sourceUseful informationQuestion still separate
The existing Google Play subscription recordThe plan type and current billing details actually displayedWhat the provider promised in the earlier LINE exchange
A prepaid plan or payment-plan entryWhether limited-term expiry or remaining committed payments need a different interpretationExpiry, stopping renewal and a refund are not interchangeable outcomes
A found LINE request and replyThe actual cancellation, pause, date or refund wording availableA request is not its response, and missing qualifications cannot be supplied from a billing date

Common problems and fixes

The membership is not listed in the Play account you opened

Google says the subscription app's email can differ from the Google Account used for the purchase. Check your own known purchase account on the computer, or skip the Play branch if the membership was bought elsewhere. Do not add or remove phone accounts or change another subscription to test recovery. Continue reviewing the local LINE scan independently.

The membership still works after you believe it was cancelled

Continued paid-period access can be normal after cancellation. Read the actual plan details rather than assuming a working app means another renewal will occur. Keep a prepaid expiry or a payment plan's remaining committed payments distinct, and review the found LINE wording for the specific change the provider discussed. Confirm the current billing position with the provider if it remains unclear.

A receipt image is found but the cancellation response is absent

Save a usable receipt if its reference helps, then inspect LINE conversation results as well as LINE Attachments. A financial reference and a provider reply can survive differently. The scan does not infer a refund decision or a cancellation date from the image, so preserve the useful actual records without inventing the missing response.

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

Dr.Fone - Data Recovery (Android) helps you look for the communication behind a current membership record. Its Windows-only Advanced Recovery mode scans supported local LINE data without an earlier chat backup, provides separate conversation and attachment previews, and saves your chosen results to PC. You can concentrate on the provider's actual reply, usable receipt images and other reference files rather than treating a plan screen as the complete discussion.

  • Read discoverable LINE text for the actual request, response, date and qualifying condition.
  • Inspect available photos, videos and files in LINE Attachments independently from the conversation.
  • Save selected useful communication and receipt references to PC without changing LINE or the billing account.

Follow the official Advanced Recovery workflow

  1. Step 1 Open Advanced Recovery for the Vivo T4

    Launch Dr.Fone on Windows and choose Toolbox > Data Recovery. Select Android > Recover Android Data, choose Advanced Recovery and click Start Scan. Connect the supported Vivo T4 with a USB cable when prompted and follow the on-screen directions until the phone is detected.

    Select Standard Recovery or Advanced Recovery
  2. Step 2 Select LINE as the app data to scan

    Choose LINE from the available categories and click Start Scan. This searches the phone's selected app data for the missing exchange; neither an earlier LINE chat backup nor access to Google Play billing is required.

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

    Let Advanced Recovery scan with the USB connection intact. To stop, click Cancel before disconnecting the cable. If the phone is temporarily unresponsive after scanning or recovery, follow the restart instruction shown by the product.

    Scan Android app data with Advanced Recovery
  4. Step 4 Preview the reply and attachments in their own views

    Choose LINE in the sidebar and inspect available conversations for the membership discussion. Use search or filters where available and read the actual response. Select LINE Attachments separately to browse found photos, videos and files. Choose useful messages and usable attachments without assuming that one result guarantees the other.

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

    Click Recover and follow the prompts to choose a folder on your PC. Complete the save, then open the output to inspect the selected reply and reference files. These are PC copies, not messages inserted into LINE or an update to the membership status.

Conclusion

For a missing membership reply on a supported Vivo T4, Dr.Fone - Data Recovery (Android) helps you look for the actual LINE response, preview available receipt photos and other attachments, and save selected useful records to PC. Download Dr.Fone for Windows, connect your compatible phone and start the guided scan to preserve the communication behind your membership decision.

FAQ

  • 1. Can I recover deleted LINE messages on Vivo T4 without a backup?
    Dr.Fone - Data Recovery (Android) provides a local device-scan route for supported Vivo T4 data without an earlier LINE backup. Use Advanced Recovery on Windows, retain the listed Kernel 6.1.145 condition, review LINE and LINE Attachments separately, and save selected discoverable results to PC.
  • 2. Does continued Google Play subscription access mean cancellation failed?
    Not necessarily. Google says a cancelled subscription remains usable for the time already paid. Inspect your existing plan's actual details: a prepaid plan ends after its limited term, while stopping a payment plan's renewal does not erase its remaining committed payments. This optional billing check does not recreate the missing LINE reply or decide a refund.
  • 3. Will creating a LINE backup now restore a manually deleted conversation?
    No. LINE says a suitable Standard Backup must predate the manual deletion. Standard Backup saves text only and is for same-OS transfer; a new Standard copy or Premium Backup does not roll back that manually deleted history. This article uses local scanning instead of presenting a new backup as a recovery method.
  • 4. Can Dr.Fone recover deleted LINE photos and videos to the T4?
    Inspect LINE Attachments for the actual photos, videos and files the scan finds, then select useful items to save to PC. Advanced Recovery does not write them back into the phone's LINE chat. An expired original that has no discoverable local data is not guaranteed to appear.
