As we all know, surfing the Internet with a device that no longer gets security updates is a sure recipe for getting hacked.
If I have a Samsung Android device, how do I find out whether it is still officially "security supported" (i.e., whether Samsung will push an OTA update when a security vulnerability is discovered) or not?
If I consider buying a new Samsung Android device, where can I look up how long it will be security supported by Samsung?
(I don't care about feature or OS version upgrades; this question is only about security updates. In addition, let's keep things simple and restrict this question to devices without a carrier lock - I know that carriers can delay updates, making matters even more complicated. I am looking for something like this for Samsung Android devices.)
