you can do it manually, like you did on unofficial, if you want.
or just use the ota updater in settings. it runs in the background doing the install to the other slot and allows you to continue to use your phone. just like getting updates on stoc...
I think this bug was already in the old build..
Benzo ROM has an Kernel Manager?
My bad ! I didn't read it clearly kernel manager ! ^^
Am using kernel auditor.
I came from stock to this Rom. Stock Pie gets my phone hot easly and Battery dies quick. After installing Benzo and Elemental 4.07 kernel, my phone doesn't get hot anymore, feels much smoother and battery lasts me a full day before recharging.
