I had used ' Samsung Galaxy C9 Pro' which has some featurs good but it' s price are very high which are not affordable to many peoples. It has ' Rare camera & fornt camera are same of 16 MP' which not gives much clearity. It has battery of " 4000 mAh" which not gives enough battery backup.Also it has a problem of hanging many mobile phones of samsung gets hang and shows massage of ' NOT RESPONDING' . It took very much to get charge by its original charger.
