Not all of Android’s advancements have been positive. Due to the platform’s open nature, bloatware and unwanted carrier modifications have become the norm for smartphones everywhere. Unless your phone is made by Apple, chances are good that your carrier has tampered with the device in some way, either by removing features or by installing apps. What’s worse, you can’t uninstall any of the junk without rooting your phone and voiding your warranty.
Of course you could always get a Nexus ... provided that you’re on one of the two carriers that support it and you don’t mind breaking your contract to get a new phone.
