While the Nokia X is already on sale in some markets around the world, the two other Android-based handsets that Nokia announced last month - Nokia X+ and Nokia XL - will be released a bit later. The good news is that, unlike the Nokia X, the XL and X+ will have 4GB MicroSD cards pre-installed, so users don’t have to worry about the rather low internal memory that the phones are offering (4GB). Nokia confirmed this today on its Conversations blog.
Both the Nokia X+ and Nokia XL should be launched in the coming weeks, or maybe months. The X+ is similar to the Nokia X, but has more RAM (768MB vs. 512MB). The XL - seen in the gallery below - has 768MB of RAM, too, and is larger, sporting a 5-inch WVGA IPS display, a 5MP rear camera, and a 2,000 mAh battery.
Nokia also confirmed other things about its X line of handsets. According to the company, there “aren’t plans” to bring its PureView technology to the Nokia X phones - but this was expected, since we’re talking about entry-level, cheap devices here, and PureView is reserved for high-end Windows Phone Lumias. As for why the X line isn’t based on a newer version of Android (it’s using 4.1.2 Jelly Bean), Nokia simply says that it chose “the version with the broadest mainstream reach.”
