I didn’t need windows anymore so I deleted it. I installed Bliss 11.11 in this way: Booted the chuwi hi12 from an USB key created from Rufus with Bliss 11.11 ISO file, erased all existent partitions in chuwi (windows and android). Made a second boot and selected “automatic install” option. That’s all. Anyway unfortunately I realised today that after a while wifi signal stops while using bluetooth speaker… May be any interference? Tried different BT earphones and speakers… Always the same problem.. wifi goes down and never come back alive until reboot or aero on/off mode. Tried also audio extractor from hdmi… Nothing.
