Nice cellphone using it from last eight months. There is nothing any problem found in it. Volte enable phone using jio in it. Frequently updates are coming. Ram is suffient but Rom should be little higher. One thing is very very good is battery backup, for battery backup I want to give 5 star to the cellphone. Slim phone, light weighted with attractive look and again best thing is superb battery backup. I suggest every one to go for this for its long lasting battery.
