Microsoft Android Phone Ramble
The decision to make the phone two screens instead of one large foldable screen is the right way to do this.
Samsung and Huawei's foldable design is a fight with physics. Almost every material the flexes back and forth that much becomes the bent paperclip.
Waiting to see what other manufactures do now that this has been announced.

LG also introduced a connectable second screen for the LG V50 thinq and LG G8x. Seems like a good compromise.

I like LG as an Android smartphone supplier, because they tend to throw everything and the kitchen sink into their phones and see what "sticks".
