I doubt very much your phones have been hacked, certainly not four in a year
Possibly you are installing the same apps on the phones and one of the apps you have given permissions to is reading your data
All you can do is change all the passwords on the accounts you have and look at every app to see what permissions they have.
Also try installing a good antivirus (such as Malwarebytes) to check for malware on your phones
