Hello friends! I show j7 duo phone. it is only famous phone. their battery backup initially give better service but after 2-3 months, it’s battery backup is not sufficient. This phone is also warm when charging. I see, there battery power is low 3000mAh only which is law power comparison to price. There front camera is good, it is 8MP and their display is also good as showing video. It’s back body is so cute. But it is not strong. Its RAM is large comparison to other phone 4GB.
this phone is costly then xiaomi phone. So, generally people uses xiaomi phone now. I like Samsung but it is so costly. Samsung is good phone but not successful.
