However, since most phones now tend to reach the "good enough" level, my main question is about software and left unanswered. What version/flavour of Android does it run? How will updates be planned? For how many years will updates be provided? What's the size of the security team at Essential?
Providing an up-to-date Android with updates for at least 4 years like Apple does is key to me, as vulnerabilities come and go and the only reasonable way to be secure is to get security patches asap.
