The Nokia Lumia 625 will supposedly be launched with a 4.7 inch panel featuring WVGA resolution. That does not work out to a splendid pixel density. A dual-core 1.2GHz Qualcomm Snapdragon S4 MSM8960 processor is under the hood, but only 512MB of RAM is on board. The model will have Windows Phone 8 with the GDR2 update pre-installed out of the box, and will be equipped with a 2000mAh battery. Besides having a unibody design, the unit will offer LTE connectivity. Nokia is said to be aiming to offer the cheapest LTE enabled phone with the largest display among Lumia models. If it is announced next week, expect the phone to launch as early as next month.
This is alleged to be the 4.7 inch Nokia Lumia 625
Another surprise is that the Nokia Lumia 928 is not expected to be one of the models introduced at the event next week according to information received by My Nokia Blog. The phone was spotted on a billboard in the U.S.last week and has just been seen in a layout in Vanity Fair along with an appearance on Verizon's website. It had been expected that this model would be one of the phones to be introduced next week in London. Instead, we might see the device get unveiled in the U.S. shortly.
