Isn’t it an open secret that powerful entities (like spying institutions) can get into pretty much every system if they have physical access? Why is this not plausible
You stated in your original comment: “pretty much every system”. So no, any modern phone if android or iOS is by default encrypted.
If the key for the encryption is on the device, and either stored in an unencrypted TPM or unencrypted storage, its not a matter if breaking the encryption (quite impossible) but breaking the software/hardware (quite possible for someone with good enough forensics and skilled programmers)
TPMs are by design encrypted.
Keys are not stored unencrypted at least not when you encrypt your storage with modern solutions and set it up reasonably. You use either your TPM to store the key or store it on the drive and have it encrypted by itself or use a KDF.
Also also: encryption only helps if the device is off, which is seldom the case with phones.
No this assumption is wrong. You still would need to circumvent the Login into the device which is mostly secured by a pin or password or biometrics.
If you think TPMs are always encrypted, a key can be encrypted “with itself” and still be any use to you and android system pin is secure you are right.

As i guessed. You are evading the question by again babbling nonsense and questioning my knowledge instead of actually proving anything you are saying.
You have shown that you have a bad understanding of what you are actually talking about (see the ‘cracked’ TPM discussion) and constantly shifting the discussion away from what you are saying : “Basically every device can be accessed without major problems” and what i am trying to explain to you.
You keep referring to concepts like
“Keys encrypted with itself”
“Tpm are by design encrypted”
When you don’t really say anything from value.
Not every “encryption” is the same.
When we talk about safe encryption we talk about file system level encryption of a system with safe algorithms like aes and a long enough random password (the key). this is safe.
If you store the key unencrypted on your phone, this encryption is no longer safe.
If you don’t know the 16 random digit key it HAS to be on the phone and it CAN’T be encrypted “by itself” because you would no longer have any means to decrypt it.
It could be encrypted with a pin, but again, then its only as strong as the pin, and I don’t know how long an only numeric pin would need to be to withstand modern brute forcing, but I doubt a relevant percentage of people have that kind of pin.
You can’t explain how this would be safe, so you just come at me with russels teapot and say “well you can’t prove its not safe” (which is true because I’m no security expert, but someone with enough knowledge could certainly) and lash out at me “acting in bad faith” because I don’t jump through your hoops of passive aggressive misunderstanding.
All I can do is refer to experts, who found things like CVE-2022-20465 - a bug which allowed lockscreen bypass.
As you could have googled that yourself, but you ask this just to throw me off.
But if you want to keep using your google android and bitlocker win and feel safe, its not my problem.

Not sure what you are rambling about the TPM.
Then prove that the Lockscreen is insecure.
How do you think encryption works?
What do you think does a lockscreen?
