A user by the name of Lime compiled a few indicators of less-than-stellar software into a single post in the Reddit community r/Android. The post doesn’t mention any hardware flaws, which is mostly a good thing, as it means that users who are currently dissatisfied with the Phone (1) can hope for a fix. On the other hand, multiple issues surfacing at launch imply that the software may have needed more extensive testing prior to release.
Based on a review by the German website Computer Base, the phone has issues with Google Pay that mostly seem to stem from a lack of compatibility between the service and Nothing OS. The Phone (1) meets resistance with Google Pay, alerting the user that “Ihr Gerüt erfüllt nicht die Sicherheitsstandards” — effectively saying the phone does not meet the app’s required security standards. A phone failing to meet security standards prompts Google Pay to assume that it’s rooted or runs uncertified software. For people who frequently use Google Pay, that’s bound to be a nuisance.
Update: Again according to Computer Base, this issue has been rectified with an update to Nothing OS version 1.1.0.
