BLOCK ADS FROM YOUR DEVICE!
Note: The process described below needs a rooted android device. If you dont have a rooted device, then please dont try it. If you never heard about android rooting, then probably this post is not for you.
Why waste internet data in watching ads in apps/games etc? I know those ads generate revenues for the developers but whats the profit if you would never want to click them? Better to kick them out!
The process described below is for advanced users only. Have a nandroid backup before you begin!
Benefits of Using Ad Blocker:
1. No useless Ads: Never ever get irritated with intrusive ads that makes your game slower or interrupts your reading.
2. Save internet Data: Ads consume upto 10MB per month. Also it refreshes every few seconds to load new ads. That will eat up your precious data. Using adblocker, you are protected from all these.
3. Be smarter: Get ahead of your friends. Your device has no place for ads like your friends! 
Cons:
1. Needs Rooted Device.
2. Process can be extremely harmful, and can permanently damage your device.
3. Developers of apps wont get paid. YEA IF YOU USE AD BLOCKER, I MYSELF WONT GET PAID. SO WE ALWAYS SUGGEST YOU NOT TO USE IT SO THAT WE CAN EARN A BIT, ITS FINALLY YOURS DECISION!
