Do not go for X2. The Nokia X series is a sorry excuse for android devices. The Nokia X series comes with a modified version of Android, which is different from the Android OS you will find on other Android devices like Samsung and LG. Because of this, the Nokia X does not come with a Play store, but instead comes with a Nokia app market that features popular android apps. Also, because the Nokia X series phones comes with a modified version of Android, Google supported applications such as Google Search, Gmail, Google Maps, and so on, are absent. What you will find on the Nokia X series is Here Maps, Bing Search and other poor substitutes for Google applications. The Nokia X is difficult to navigate around and doesn't feel buttery to the fingers when swiping around the screen. In summary, the Nokia Android devices are not all that. They are new to the market and do not have outstanding features. Besides, Nokia no longer makes Android phones. The Nokia X series is their last. If you want to purchase an Android device, I suggest you go for Samsung or LG.

I'd pick the Lumia 630. It comes with the version of Windows Phone (8.1) which means improves features. I disagree very much with GSMArenaNG. Yes, the RAM might differ, but otherwise the Lumia 630 will give you the same service as other Lumia phones. It might not have a massive camera and all that, but that doesn't make it less of a Windows Phone. Besides, the Lumia 630 comes with a better battery power and an internal memory of 8GB and card slot of 128GB. The Nokia X2 comes with his 4GB, card slot of 32GB.

In my opinion, Lumia 630 beats Nokia X, hands down.
