- In order to overwrite the old data in my phone, I filmed a short video with the camera and then copied and pasted it many times until the phone’s memory was full is this method considered correct and effective for overwriting old data?

If would help if you stated what phone model and which version of Android it's running.

Keep in mind that the internal storage media in any Android device is divided into several different partitions. Most are dedicated to the operating system, and only one is set up as the user data partition. You can write and re-write files continuously several times and that only affects that one user data partition. All the system partitions are left untouched and unaffected as you, the general user, have no access to those restricted system partitions. So yeah, your files and saved data get wiped but anything you had set up previously like your Google account that gets assigned to the phone during that initial process when you first got the phone will still be there.

And no, just copying a video file repeatedly isn't the optimal way to overwrite previously existing, old data stored on NAND flash storage media. Android's basic file management is more involved as far as how data gets written and read to internal storage chip. You'll have better results just using the Settings menu or Recovery Mode than just copying even a really sizable file over and over again.

How old is the phone. Unless it's positively ancient (like originally released with android 4.4) the storage would be encrypted anyway, so the data would be unrecoverable anyway.

But sure, if overwrote everything then that would be extra insurance.

Android devices starting with Marshmallow (version 6) have encryption enabled by default so the internal storage in your A50 doesn't require you to manually write a video file over and over again to clean it up (Just doing a Factory Reset wipes the user data partition and the encryption prevents otherwise open access to previously written data.)

i know but I've heard before that there are a forensics programs available on the Internet that anyone can use to decrypt the (fbe encryption) to the phone after doing a factory reset... It is said that there are forensic software name OxygenForensics that can decrypt her and can recover deleted files But I'm not sure about the information, That's why I ask , others also say that encryption is not a big problem for them That is why I am not sure of this

Oxygen forensics says on it's website that it is for law enforcement, federal agencies, and corporations. It's not for everyone.

So I doubt that most of these types of software is not available for everyone.

There is a program available on eBay called ufeed, and this program is considered forensic, because this program decrypts data after formatting too
