[Q] Increase internal memory and RAM topic

Hi guys, I would like to increase the internal memory and RAM on my low end Android phone, using the SD Card. The sd card is class 10, but the phone is not rooted and I'm not sure I can find a method that will root it. So any ideas on how to do this on a non rooted device?


the phone is

BLU Dash 3.5
chipset is Mediatek MT6572M
