Recent reports indicate the best selling Windows Phone is Nokia’s Lumia 520. If true, it makes sense why Nokia is launching the Lumia 525 as a successor. The only change in this model appears to be a doubling of memory from 512 MB to 1 GB, allowing more apps to run simultaneously. The handset will also support interchangeable covers in different colors. To keep costs down, the handset uses an older but still capable 1GHz Snapdragon S4 processor, 8 GB of internal storage an 800 x 480 resolution 4-inch touchscreen and support for 21 Mbps HSPA+ networks in lieu of LTE.
