Some days ago I rooted my J320-F but I saw that my phone is lagging so I search fast for a Firmware on www.samsung-firmware.org and flash it with Odin. But still. It wasn't pretty smooth like before. On the website are 3 different version of the Firmware for my region (ROM) and I don't now which one is my original one. How can I find that exact version. I can give more details if needed.
Thanks!
