Oppo a3s is the best affordable phone. This phone comes with 2 variant 2 gb or 3gb ram. The oppo a3s brings a 6.2 inch hd display which has good brightness. The 720p resolution also give sharp and detailed pictures. oppo a3s is a Snapdragon 450 chipset. the oppo a3s has 4230mah battery which is the probably tha biggest highlight of the device. But it takes well over 3 hours to charge the device from zero to hundred percent and fast charging is definitely missed here. Personally I used oppo a3s the phone is very awesome.
