I did a clean install but it was very laggi fom time to time. I've never experience that on rootbox! I been testing it 4 two days and now that I returned to rootbox I must say it's much much better. I like slim because of simplicity, light weight and real dark option but lag was 2 bad 4 me. Now that rootbox have dark option I'm quite happy with it. Keep up the great work C3CO I'm always more than happy 2 test your roms!
