I am using Redmond prime 2. Ah man the phones is getting heated up on 3G network. Not only on 3G networks but the phone is heating a lot while playing heavy games above five minutes, the amount of heat is more than other phones that Ive seen.
Xiaomi redmi prime 2 is surely the cheapest phone around with the specs its given but its not up to the mark with its quality. Some other Chinese company are better. Just wait for another release.
