Using open-source software running on Raspbian, with parts easily obtainable on eBay for about $50, you too can build yourself a smartphone. Arsenijs explains how.

It's Linux, and the apps running on it are open-source (therefore more likely to be secure and not privacy-invading). If you don't like a feature because it's a privacy/security concern, you can just disable it. If an app you're using has any unwanted code, you can just remove it. It doesn't depend on any butt^W cloud services - not if you don't want it to be. Since, again, it's Linux, it's got many security-related software available, and you can install it - be it a firewall, I2P/Tor node or a secure messenger of your choice.

As a bonus, the software is meant to allow you to fully utilise all the features the hardware supports - including some manufacturers don't usually include in software but surprisingly helpful. For example, you can use modem-specific commands - that allow you to detect GSM jamming, fake GSM base stations and intentionally weakened GSM encryption (I know SIM800 has the first and provides data to help with the second, for a start).
