This browser proved extremely snappy and beautiful in my phone . Just to say I have a crappy device with a meagre 256 kb ram and 30 mb storage left . So I was searching for a browser like this. But the only reason for my unistall was that it crashes everytime I open the Google search . Or just search any thing . But websites like youtube and Facebook were running real smoothly. I swear this will be my permanent browser if u fix my issue. Atleast gimme a reason why its crashing!"
