Design Good, Performance is better, No Heating Problem, Like system ui and other new devloping mod Problem 1) Charger output is high 1.15A it good battery charge is fast but also drain is very fast same note using phone. I m charge phone 100 battery also drain 70 not use( Now solve this problem I m use my old grand 2 mobile charger it is output 1.0A. Drain problem solve) So you have keep focus in this problem 2) camera result is not expected. 3) Giving Less Sensor. Your software update service is poor. So I hope you have upgrade software system and develop 6.0 to 7.0 android system. > I m using last 3 phone in samsung it 4 phone good android devlopment and very changes compre old phone.
