I got a Samsung S21 FE 5G as an award on a programming competition. OEM unlocking wasn't even an option in the developer settings until I connected the phone to the internet and set the date to one month in the past (I assume this has something to do with the warranty -- you can't even unlock the bootloader right away). An internet connection was required before even using the phone on the Android initial setup scree…
I liked my Samsung phones but after the a couple of them went end of life despite being very usable I am never buying one of their devices again and sticking with Pixel. There should be an Android code of ethics or regulation to unlock bootloaders of these devices when discontinued to minimize eWaste.
It always cracked me up that Apple gets bashed for planned obsolescence when they support their phones longer than anyone else in the industry.
