I have a really old Moto android phone with a headphone jack that I use with Lannouncer to do TTS though my in-home intercom from Hubitat. About once per year because I created a firewall rule to prevent this phone touching the internet it goes frenzy trying to update certs and make the call to the mother ship to do other things.
The annoying thing it beeps every time one of those activities fail thus beeping on all the intercom speakers in the house. All I usually do is remove the rule blocking access connect back to WiFi, validate my google account and everything clears up. Then I just re-enable the blocking rule and usually good for another year.
But this time a message popped up after I validated my google account. It stated that this device is no longer secure and will be disabled shortly in the future because it no longer meets security standards. I know Louis Rossman has had comments on if you own the hardware, you purchased if a vendor can just remove your ability to use it. But really Google you are going to remote brick this phone?
Just wondering if anyone else has had a device that the vendor decided you don't need to use anymore?
Been down that rabbit hole many times early in the Android days and still have nightmares of not being able to access core Android services because the bootloader isn't secured.
Yep I watch the video's on YouTube from Lewis, Just think of the latest, Amazon stating you don't have rights to have local copies of books on a Kindle anymore. Even though the content you purchased a license for was the right use it on the Kindle platform.
It's interesting that I have the same setup, except my moto phone is never allowed to access the internet. It has been working great for years until yesterday when it seems to be working but is not receiving any inputs and so is not announcing anymore. Logs show commands going out, and Lannoucer says it is listening. So I can't find anything wrong except maybe what you suggest, maybe Google has pre-planned to stop this device even if they never get to contact the phone. This means they have pre-programmed it to stop working a long time ago.
I really believe that Google and the phone makers have built in kill switches. So what I have done is resurrected a old Moto BackFlip that hasn't see the internet for years and was one of my first Android phones. I have apk's I just loaded and went with 2.4 Ghz Wifi only and with the mac address permanently blocked though my router. Back then Android didn't do mac address rotation so I am pretty sure it will never ever hit internet. As for sim cards none inserted.
