Try installing crossbreeder (you can find it on xda). It helped me a lot with sense 4.1/4+. Speed of UI and network was increased a lot and it has faster method of blocking ads (instead of hosts file method which can produce some delays while loading pages).
Hit "Thanks" if I helped you in any way!
