Every brand is giving a special feature ofblocking internet and wifi for a particular app in their userinterfaces but samsung is lagging behind in introducing this feature ..hope it will come in one ui 8 stable update
Samsung should give option to their customer for downgrade . After every binary change samsungs monopoly is not allowing their customers to downgrade. After 6.1.1 update i m getting only 4 to 5 hours SOT
