Voiding your warranty: Some manufacturers or carriers will use rooting as an excuse to void your warranty. It’s worth keeping in mind that you can always unroot. If you need to send the device back for repair, simply flash the original backup ROM you made and no one will ever know that it was rooted.
Security risks: Rooting may introduce some security risks. Depending on what services or apps you use on your device, rooting could create a security vulnerability. For example, Google refuses to support the Google Wallet service for rooted devices.
