Z5 Compact unlocked bootloader - problems that may occur

Now that we've confirmed that even the new sony z5c will lose your DRM keys if you use the Sony official way of unlocking.

As most people have tested, the phone camera seems to be okay right now.

If you have any problems that is due the unlocking bootloader, can you please post it here so people can make a judgement if unlocking is worth it or not.

Thanks :)
