Galaxy A7 and A5 (2017) come with 16 MP front cameras, which is the same resolution as their main shooters, while the new A3 has an 8 MP one - all upgrades from Samsung's resident 5 MP front camera that was utilized last year en masse, including in the Galaxy S7 and S7 edge. For the Galaxy S8, however, Samsung is allegedly prepping an even nicer surprise - an 8 MP selfie-taker with encoder type autofocus actuator, instead of the usual VCM type, which would allow for a slimmer AF module.Thus, the
Frontal cameras are typically a fixed focus affair, and autofocusing has been reserved for their rear brethren, but, given the importance of the selfie cameras these days, Samsung has rightfully concluded that this upgrade will be something users need and want. This is not the first time we are hearing that the S8 will get rid of the fixed focus front shooter, either, so where there's smoke, there could be fire. The entry-level Galaxy J series is also getting a 2017 refresh this March, claim the industry sources, and will also be receiving a significant front camera upgrade. Good times for narcissistic personalities.
