As soon as I opened the Weather app to enter a manual location the Biss app generated an error and then the screen began to flicker on-off. During this time I had access to the side buttons was able to shutdown or restart. After a reboot the same continued. At one point I just left screen flickering and it finally shut down with app error.
I was able to roll back to 1.6r.
