With the introduction of the Lumia 630 and 635 models, we have our first look at the next generation of low cost Windows Phone devices, and the Lumia 630 is a phone with many firsts for this segment. It’s the first phone launched with Windows Phone 8.1 from any manufacturer. It’s also the first phone released after the acquisition of Nokia by Microsoft, though the phone was announced at BUILD prior to the final paperwork was completed on the acquisition. This is the first Windows Phone ever with an optional Dual SIM model. This is also the first Windows Phone which incorporates a SensorCore branded pedometer. It’s the first Windows Phone which replaces the hardware back, home, and search keys with on-screen equivalents, and unfortunately it’s the first Windows Phone which is lacking a hardware camera button, ambient light sensor, and proximity sensor. This is definitely a device of firsts for Windows Phone, but not all of the firsts are good news.
