How can I retrieve deleted messages on android phone from my pc?

If you don’t have a backup, it’s still worth trying recovery software, but don’t expect a guaranteed result. Once messages are deleted, Android usually marks that space as available, and new data can overwrite it.

First, check Samsung Cloud, Google backup, or the Messages app trash folder (if available). If nothing is there, you can try an Android recovery tool from a Windows PC.

Most recovery programs will ask you to enable USB debugging:

Settings → About phone → Software information → tap Build number 7 times → Developer options → USB debugging.

Before doing anything else, try not to use the phone too much. Avoid taking new photos, installing apps, or downloading files, since that could overwrite the deleted messages.

Also, be careful with free recovery tools. Many can only scan and preview data, and recovery depends on whether the deleted messages are still stored on the device.
