My phone got bricked a while back and whenever i tried turning it on it gave me an error about something and it said i tripped the knox, anyways eventually i tried undoing this by searching up tutorials on my computer. I used kia everything i possibly could, until i installed new firmware on it.
My samsung galaxy grand prime is SM-G something but i installed a somewhat similar firmware. Anyways when i turned it back on it worked perfectly fine but what bothers me is that, the system memory is 3.50gb, my phone overall has 8gb, it takes up alot of space, is this normal or did i duplicate some stuff by installing the other firmware??
