Choose an Android dialer that saves accessible call recording files

Choose a setup that saves original call recordings in accessible shared storage. You need to be able to select and copy those files in bulk from File Manager or through USB file transfer, keeping their original filenames. Callery’s automatic caller and call-date organization also needs a filename layout that its parser recognizes.

A dialer that records calls but keeps the audio inside its own private storage does not meet this workflow. Exporting calls one at a time with Share is slow for an archive and may change filenames or omit the caller and timestamp. A playable audio file and a useful call-history record are separate things.

Identify the dialer and the software

Long-press Phone → App info. Note the app name, publisher where shown, and version. Also note the device model, regional firmware, and full OS build in Settings. The same phone brand can ship with different dialers and recording features.

Use the matching guide:

• Samsung: find the original files under Internal storage → Recordings → Call on supported Samsung Phone setups and copy them directly.
• Xiaomi, Redmi, and POCO: check whether the build offers a working OEM dialer and accessible originals; HyperOS alone is not proof.
• OPPO and ODialer: check official app eligibility, recording, and file access on the exact build.
• Vivo and iQOO: check the available OEM dialer and original recording storage.
• Google Phone limitation: understand why its playback and individual sharing do not establish Callery compatibility.

Compatibility depends on your current recording setup: original files accessible when the folder and metadata checks pass; OEM setup required when an applicable dialer route needs completing; or not established for this build when no working route or original-file evidence is available. A phone that currently uses Google Phone may fit after an OEM setup, while its old private recordings remain a separate limitation.

Understand accessible storage versus private app data

The Internal storage view in a phone’s file manager usually means its user-accessible shared storage. Android also has a separate app-private internal-storage area. Android documents that other apps cannot normally access an app’s private internal files. USB debugging does not turn them into a shared recording folder.

Google Phone’s help describes finding recordings inside Phone and optionally sharing individual calls. It does not establish bulk copying of original files with caller/date filenames. Google Phone, including on Pixel, is not a supported Callery archive source. Callery cannot recover missing caller metadata from an arbitrary filename, and it does not read the dialer’s private call database.

Installing another dialer does not move existing Google Phone recordings into a shared folder. Treat a replacement as a possible setup for future recordings only, and confirm it works before relying on it.

Select an OEM alternative only where supported

Open Settings → Apps → Default apps or Choose default apps → Phone app, then choose the available OEM app. Google documents these default-phone controls; manufacturers may rename the menus.

Use the manufacturer’s official distribution route where offered. The ODialer Play listing, for example, describes call recording, but installing it and finding a Record button still do not prove that the files are accessible or their names work with Callery. The Xiaomi guide also separates a community-reported ADB route from manufacturer instructions, including prerequisites, failures, and rollback. Follow the evidence scope in the device guide and confirm the result on the actual phone.

Keep the previous Phone app and recordings during the check. Verify incoming and outgoing calls with the chosen app. If an alternative is not offered or does not work on the installed firmware, do not assume that sideloading an APK or changing a package setting makes that model supported.

Complete the file-and-metadata check

1. Make a short call with participants who agree to recording, using the selected dialer’s available recording control.
2. Play the result and confirm both voices are audible.
3. Find the original file in a folder accessible through File Manager. Confirm you can select multiple originals and copy them together.
4. Copy a few files directly to your computer. Compare their original names and extensions before and after copying; do not use the dialer’s Share action for this test.
5. Import the sample into Callery and check playback, caller, and original call date. A successful upload alone does not verify the metadata.

If the folder or metadata check fails, the setup is not ready for Callery’s supported archive workflow. Callery accepts MP3, WAV, M4A, MP4, and WebM, but file-format acceptance does not make a dialer compatible or restore lost filenames. Continue with the bulk backup and import guide after these checks pass.
