My girlfriend just got this phone, and the first thing i did was root it, debloat, and install the basics. (Xposed, a few modules, Viperfx) Before, and after, doing this, the phone is rather laggy. Short of changing the os, which i don't plan to do, is there anything else i can do to address this issue? Ive seen some posts on xda for other lg phones that mention flashing some kind of "pure performance" file that claims to speed things up, but i dont know anything about it. Thanks in advance for any tips, suggestions.
