    The Oppo A 57 works well with basic apps, social networking and email. I wouldn’t play games on this smartphone, although, light gaming is possible. If you are doing something that is rigorous with this phone, there is a tendency for the underneath to feel warm. You must at least leave 1.5GB of RAM so that everything will work out just right. Doing this will prevent hitches. The Oppo A 57 can tackle video files up to 1080p. The speaker on this phone is not loud. The camera on the front works well and you can get very good shots on selfies. You can take good shots on the rear camera during daylight. Video recording can only reach 1080p. This is good enough.  For me 12 hours of runtime on the 2900mAh battery is alright. Just keep in mind that you are buying a “selfie smatphone.” For practical purposes, This is a good smartphone to acquire.
