Reception

The Samsung Galaxy A31 received mixed reviews with most reviewers acclaiming the brilliant screen, excellent battery life, software and overall build quality. They critiqued the performance relative to the phone's main competition, the phone's poor camera quality, and the lack of a night mode and various other camera features. Reviewers were also reluctant to recommend the device considering that even in Samsung's own mid-range A-series one could get a better overall package by spending just a little more money.
