Optimistic option!
I truly hope that Huawei actually launches a new smartphone OS. It would have to be a significant improvement over the mess that is Android.
A more serious question though is about Huawei's patents. If US companies are barred from doing business with Huawei, does that also prevent them from using those patented ideas in their own designs? Or, in other words, will they be forced to design American 5G from scratch?
I suppose the USians could just revert back to CDMA...
