17. What is root?
Ans : (by stupiak07)
For short. rooting let you gain access administrator right that is locked by the phone company by default. by rooting let you able to modify the system which suppose to be locked to avoid people mess up the system and render it useless.
The most common thing for people to root it is for moving those app/games that can't be moved to memory card by default which.eat up main storage which is phone inner storage. some people wanted to used custom/personnel rom that suite their usage and even some people want to use custom theme for the phone. by right, for those don't know how to use it should avoid it as it will void your phone warrany if you mess up. You no need to root if you are a normal users. You also may unroot back when you want to claim waranty
Add on: even if you moved your application to your memory card doesn't mean will free up all the phone memory as there will be package data left over at phone memory for it to run.
This is what I know about rooting. it may vary from the actual info
