Basically this phone falls way short of its mid-tier implied performance. Audio quality is horrible, sounds as if it had blocked ears, and audible blips and static whenever it detects sounds in complete silence. Camera never focuses properly or image quality is simply horrible, even on 1080p. And it runs low on RAM and crashes inexplicably at times even when i'm just browsing the internet with a few tabs. My old Samsung S3 outperformed on all counts, and its photo and audio files hardly took up as much space as the A57's do.
