both sim work in PixelExperience 9.0 and viper os!! 9.0 my phone is j53gxx(J500H) ..but not in this rom!First off thats off topic and has nothing to do with this rom. Second, this rom here, the evox, is stable. You want both sims on pie, use aex 6.6 lollipop is outdated. Laggy? What do you expect out of a budget phone? S10 quality and performance, get a s10.
You really want lollipop, odin yourself back to 5.1.1.
