13 MP Rear Camera - Beautiful Photography Made Easy
The A57 uses Sony’s extremely light-sensitive StackedCMOS sensor, as well as PDAF (phase detection autofocus) technology, so that as soon as you pull your phone out, you’ll be ready to get a great shot in an instant.
New Hand Gesture + Bokeh Effect - For Brilliant, Convenient Selfies
The A57 upgrades OPPO’s signature palm shutter function for taking selfies. All you have to do to snap a selfie is open your hand in front of the screen, leaving you free to get a stable, well-composed shot. Meanwhile, the new bokeh effect will give your selfies an effortless distinction, offsetting the subject of the photo with a blurry background.
Lightning-fast touch access - Accuracy and speed
With the A57’s flagship-level solid-state fingerprint reader, the slightest touch of your finger can unlock the device. With a hydrophobic zirconium surface, the fingerprint reader has a boosted success rate even when your fingers are moist.
Long-lasting 2900mAh Battery - More power, better hand feel
Even in its attractively slight 5.2-inch unibody, the A57 manages to pack a powerful 2900 mAh battery, giving the device just the right weight in the hand and offering excellent video playback time. The A57 clocks in at 11 hours of continuous video watching, 23 hours on the phone, or about 13.5 hours in a scenario of varied continued use.
3GB RAM + 32GB ROM - Bigger and Faster
The A57’s 3GB RAM and octa-core 64-bit processor make for powerful performance and seamless multitasking. What’s more, with 32 GB of onboard storage, expandable by a further 256 GB, you’ll have plenty of room to stock up your phone with your favorite TV shows and take them out the door.
