Sir it would be great if Samsung could provide J7 prime with Dual Volte update through OTA.. Samsung J8 has already received Dual Volte support through OTA update...

i uninstalled an app but its icon still persist on screen even after factory resetting . i am attaching screenshot... plz see if any thing could be done to prevent other app from facing same issue.

sir i was happy with marshmallow but after updating i dont like nougut... can samsung help me downgrade to marshmallow on my device.. i am ready to pay service charge for downgrading at service station..
