Root to remove unwanted apps

Most device manufacturers install online shopping and social networking apps as system apps. They start automatically, run all the time and waste your battery charge and data connection. In India, they are less afraid of lawsuits and cause data usage whether you are on Wi-Fi or mobile data. Such system apps cannot be disabled. You can get rid of them only by rooting the device. But since rooting voids warranty, remember that it is an option only for the brave.

If the device cannot be rooted, then use a task killer or a startup manager app to disable unwanted apps regularly, ondemand or at startup.
