So i was using cm12 beta for a while flashing all the updates and what not. Then my phone started lagging for no reason like everything i do it lags, so i wiped everything then flashed again and it still lagged like all the google apps started force closing and stuff. So i went back to the stock rom, but the one i went to was zv6 rooted and its still lagging and google apps are force closing every 10 minutes. Can anybody help??
