How does AES128 run on Android phones?

I have read that from Android 6 onwards every cell phone that is shipped is encrypted with AES128. I have the huawei P30 lite and haven't found anything.

How does the encryption work, when does it protect and what does it bring me?

I want to sell my cell phone and there's professional content on it that I have to delete with ishredder hats somehow only half works. Is it enough if I just put in a pin and then reset the cell phone to factory settings?

Does AES-128 mean that if I have a lock pattern inside and someone steals my cell phone and tries to get data from my cell phone, this is prevented?

AES is a tool, not a data.

Like hammer and nail.

The hammer is the tool and is not used up and the nail is hopefully in the wall afterwards.

AES is an encryption standard and is now generally available as part of the program in the telephone.

With the help of a key and data, it becomes encrypted data. Or the other way around: with a key and encrypted data, it becomes unencrypted data.

Conclusion: if there's still encrypted data on it, you need the key.

AES as a program is always available.

I can't answer your actual question more precisely. Wanted to make it clear that AES are not data.

The phone's memory is encrypted. If you lose your phone, the encrypted data can't be easily accessed.

"half working" is now incredibly concrete.

A pin will destroy the phone. A set PIN is no longer necessary if you reset the phone to factory settings.

I tried to overwrite with Ishredder, used 2 variants, overwrite 7 times and overwrite 4 times once.

I then downloaded an app to see what I can restore. Some photos have been restored but somehow doubled. Few of the pictures were not or partly not recognizable because the purple ones were or maybe broken by overwriting them.

What do you need to pry out the AES 128, I haven't created a pin myself where can I find it

Encryption is not there to break it. AES is considered safe. You need the key or suitable hardware and software for a brute force attack.

Does the Huawei P30 Lite even have such an ASE encryption

This is a function of the operating system, not the phone. To the best of my knowledge, all phones have been encrypted since Android 6.

OK thank you
