Thanks heaps for that, I wanted to check if it could have been something I had installed or some bug with the lineage version so I updated lineage, no avail, then formatted and it worked. 3c system app was showing all 4 cores firing.
Also downloaded devcheck and seems all good. I am really curious as to what caused the issue now...
