OPPO A57

Oppo A57 is much better than Vivo Y66. Although both have similar features, camera quality of Oppo beats Vivo and processor of Oppo is better as compared to Vivo. I have been using Oppo A57 from last 3 months and I didn't face any problem till now. There is no heating problem and battery lasts long up-to 24 hrs.

A57 is best.

Obviously, A57 is better as the Moto M series is the only smartphone that doesn't give its 100% when it comes to the camera. The major drawback of Moto M is that you will get a hybrid sim slot. I would say A57 is a better buy.

Moto m is better choice.
