Not going to trust Google for the hardware, let alone bleeding edge tech like foldable. Google cannot even make reliable regular phones (Google hardware issues of Pixel phones, dating way to even the Nexus phones). The fact that Google doesn't sell that many handsets to begin with, means that design flaws or QA issues can go unnoticed for generations of hardware.
Compare to Samsung who sells phones worldwide in larger numbers, and has their brand to bet on. Any faults (eg the Note 7,first batch of the Fold) are more likely to be discovered and trigger learning and fixing/improvements.
