I'm not a Smartphone addict, I never interested in the features of Smartphone or which Smartphone is best for me. However, as a DIY enthusiast, the Seeedstudio RePhone catches my eye.
The open source hardware manufacturer (SeeedStudio) published the world's first open source, modular Smartphone (RePhone) in Kickstarter on September 23, 2015. RePhone is a GSM +BLE (Bluetooth Low Energy) phone, future version will support 4G LTE. I own a RePhone DIY Kit from Gearbest.

The ESP-07/ESP-12 is a generic ESP8266 module which have no bootstapping resistors on board, insufficient decoupling capacitors, no reset circuit, and no USB-serial adapter. This is an article shows you how to connect the bootstapping resistor to the ESP-07 module and upload sketches onto the ESP-07/ESP-12 using the familiar Arduino IDE.
