Android 4.1.2, Launcher is Smart Launcher 2(With Dream theme mixed with the default KitKat clock and Numix Circle for some icons), the semi-transparent notification bar comes from GravityBox
Smart Launcher is great, it is lightweight(My phone is kinda old by now), it sorts apps into categories and it got a nice feature, each bubble can open 2 different apps, for example, the FB icon opens Tinfoil if I click it once, if I click it twice, it opens the FB Messenger app, besides that, the free version can do everything that I really need(like notifications in an app's icon).
(I would post a picture of my tablet, but it is kinda dull, but it is basically Nova Launcher and Numix )
