So, to recap, you have not provided any source that suggests modern Chinese devices that are in production today are vulnerable, or any less secure than ios or android. The brute force support is not for the new devices according to your link. It's for the older devices. I specifically screenshotted the relevant text in the last reply. The fact that a old device could be brute forced does not extend to the argument that new device can. There is no logical reason to suggest that.
Your assertion that pixels, graphene and iphones are safest against the hardware/software tools the police have is not backed by facts. The capabilities of these toolkits DO NOT back up your assertion because they do not show that CURRENT devices are more vulnerable.
There is nothing that would convince me of your point because your point is not based on facts available to us. It's based on your assertion that android and ios are more secure which is not supported by evidence available. If you were to provide concrete proof that these devices that are currently on sale are vulnerable, then we could have a discussion about that https://consumer.huawei.com/en/phones/
And given that there is no evidence available to suggest that Chinese devices are more vulnerable, then the next question to ask is which vendor is more likely to be compromised. The answer there is obviously that it would be the American vendor.
