How to remove a device connected to Google ?
 

I should ask this question in the Google forum, but for what I can see that's not the right place to get useful answers, the same I can't get useful answer from MS for windows problem, only experienced users know the trick to fix those problem !


I have few Android devices sharing the same Google account, some of them are no longer in use, but there's no way to remove them from Google, I remember I can do that before, now I can only sign off the device but the data still in Google. The other problem kept bugging me for long time was the duplicated contacts. Since I used the same account for multiple devices the contacts are the same, I don't know why Google keep multiple contacts. Even worse Google duplicates the same contact from different apps such as Whatsapp, Zoom, Signal....etc., those contacts are originated from the same source.


Now I download my contacts on Google after clean up, and then remove all contacts I can find on Google, then remove all contacts on all my connected devices, and remove all backup from Google Drive, and I clean the bin, but I still don't see any space regained, will that takes 30days to clean up ? anyway I backup all my devices to Google again, and upload a copy of contacts I downloaded before, and wait to see the space I've got, the problem is Google keep changing things and holding my data that I can no remove, I doubt I'm alone on this and need your help to better manage my a/c thanks !

Having your own email server, can be a good way to back up google email. Don't know whether the deleted stuff really goes then or not though. Solution could be not to use google but nextcloud???

I know, it's a google world, out there!
