It could be for compliance with Japanese law which forbids taking photos without a shutter sound? This in principle doesn't apply when you're not in Japan, but after unlocking Samsung has no way to tell. Edit: reading the article about SONY ( https://www.xda-developers.com/sony-xperia-android-pie-unloc... ), DRM keys seems to be a more likely cause, which drcursor's comment also mentions.

I can almost guarantee this is due to licensing issues with the camera firmware. Modern cameras aren't just hardware any more. They're a mix of hardware and advanced processing algorithms that really do make a huge difference in the final output. Those algorithms are often licensed from 3rd parties with specific licensing requirements.

Sony has been reasonably good about enabling open-source and fixing these things in the past, so I'd give them the benefit of the doubt that they'll try to find a way to enable the cameras on unlocked phones in the future.

In the meantime, I will only buy what ACTUALLY gives me control RIGHT NOW, namely, what is supported by LineageOS:

Japan's cybersecurity minister was proud of never having used a computer (https://www.theguardian.com/world/2018/nov/15/japan-cyber-se...). What do you expect from such ignorance? Laws that make sense (like holding creeps accountable)?

The new Samsung phones are less attractive for many reasons. A few months ago I upgraded my S8+ to a S20+. I considered the S21+ or Note, but none of those have a microSD slot.

I suspect that my next phone will be one of these: https://puri.sm/products/librem-5/

I have one of these on the way and never intended to root it, but this outrages me. I get that Samsung reserves the right to say "its been rooted and is now longer certified "safe" by us, but BREAKING the functionality of the device that I paid for and own is vandalism.

You can cancel or return it. Money is a signal every company has to pay attention to.

The average consumer only wants to purchase the cross-section between what is the cheapest and works the best. For most consumers Open Source is not a feature.

BTW there is no law in Japan about shutter sound, makers are following the consensus by their own will (don’t want to be the only ones to not follow)

This is usually just a trivia, but in these cases it’s informative on what length makers feel obligated to go to protect that shutter sound part. Which is, not much in general.

If you use a foreign SIM card it won’t follow that rule, same for some of the capture modes, etc.

"Re-locking the bootloader does make the camera work again, which indicates that it’s more of a software-level obstacle. With root access, it could be possible to detect and modify the responsible parameters sent by the bootloader to the OS to bypass this restriction."
