here are two main disadvantages to rooting and Android phone;
Rooting immediately voids your phone's warranty-Once rooted, don't try to bring your phone back for service or warranty work. You are on your own!
Rooting involves the risk of "bricking" your phone-In essence, a "bricked" phone is no better than carrying around a brick in your pocket. The phone is dead when it has been "bricked."
Other potential disadvantages, though less severe, are still worthy of consideration;
Poor performance-Though the intention of "rooting" a phone is to give the phone more performance, several users have found that, in their attempts to speed up the phone or add additional features, that their phones lost both performance speed and features. Remember that when you "root" your Android phone, you are making changes to the stock operating system.
