"The Android version of COCOA, an app for confirming contact with patients with new coronas, has been effectively disabled since last September, and the government has apologized"

People with Android phones should be outraged, and the government should apologize for scraping its head on the floor. That's fine, and that should be.

It is outrageous that the system has not been functioning since the end of September 2020.

I also think that people who have Android phones can file a lawsuit under the State Compensation Act against the government on the grounds that they have been put at risk

(I think this is equivalent to "gross negligence" under Article 1, Section 2, but I know it is difficult to determine the damages.)

That's why, as an engineer, I'm the only one who's willing to say it.

"Android phones do that a lot, don't they?"

I have always thought that it would be a good idea to distribute dummy software that simulates an infected terminal.

I think that the distribution of the simulated software can be limited to only IT experts (i.e. me) who can handle at least public key cryptosystems.

I think it would be preferable for COCOA to display one or two messages a day that say, "Your phone has confirmed a reaction to the test terminal, but it is not contact with an infected person.
