Question Dead phone file recovery software?

Dec 29, 2023
I have an old Galaxy j7 that is inoperable. It shut off one day and never was able to turn on again does not take a charge anymore. There is a lot of software ads that claims to recover files from dead cell phones but I have found it that's not true.
Can somebody recommend one that you can actually plug into your dead phone and it has the ability to scan and retrieve files, photos and messages and such?
I contacted one of those companies that does file recovery and they want anywhere from $300 to $800? Thank you
