I reverted back to "5.90 XZ" version on my Z4, because the "Z4/Z5" version suddenly went crazy, ISO and EV don't work as they should.
ISO 50 | EV +1
It looks like the ISO is totally broken.
EDIT: suddenly even the XZ version also broke. I don't know what's wrong, but on my firmware, MROM v3.1, something don't work with these releases. Maybe I should install the official firmware... but not now. LineageOS is flopped for Z4 and Z5 series, so I have no choice
