LG G Vista 2

Hello guys :3 I have an LG G Vista 2 and it's kinda slow, and I want to root if. I've tried everything including kingroot which didn't work. Kinda stuck as I know this phone has a lot of potential it's just laggy. Any answers to lagginess? I constantly have cleared my recent apps, and the storage space on here is definitely OK. RAM is OK. Battery saver is off. Why so much lag on my two dots game? My old g2 runs it better. Sorry for the long list, but I hope y'all can help me. Thanks ~ Sky
