There are always two categories of users in the technological field, those who buy and use the technology as it is offered, without asking questions and those who want to understand what they have bought, trying to make the best of it, strengthening it if possible. This rule applies to computers and also to mobile phones. When you buy an Android mobile phone, a Nexus, HTC, Samsung or other brands, you find a system that works well with several applications already installed and a graphic setting decided by the manufacturer. To expand its potential, an Android mobile phone must be freed from the manufacturer's constraints thus making it possible to fully exploit the processor, the memory of the SD card and obtaining full freedom to install any type of application .

These are 40 of the best free apps for Android for root unlocked cell phones, which also represent most of the reasons why I recommend everyone to unlock their cell phone.
