Hii .I am using reddi 4a mobile from 4 months.It is very nice experience with this.It has 3 GB RAM and 32 GB total available memory.Front camera 5 MP and rear camera 13 MP .Camera quality is very good and very good pictures can be captured.Battery available is 3120 mAh .Battery backup is good.It has very good features.The disadvantage only is if we want to use external memory card then it will be a single sim phone.Dual SIM with SD card is not possible.But if considered with the cost then it is a good choice with good feature at affordable price.
