what is the J2 kernel ?
mainline, with libhybris, with Halium ?
does it depends on s proprietary blobs like Sony devices?

If the question is about the new Jolla Phone (Jolla Phone Pre-order Voucher – Jolla Shop), it’s quite unlikely that it will run a mainline kernel out of the box. It will probably use libhybris like all other ports officially released by Jolla so far. But just like with the C2, it doesn’t mean it has to run this one specific kernel, the community can still create different ports.

Ah sorry I misread - J2 not C2. Ignore me :slight_smile:
