What I understand the 925 is one step forward, two steps back, when compared to 920. The camere has an extra lens, but has a weaker flash! Its thinner, but no wireless charging. Its lighter, but only comes with 16gb, ublike the 32gb Lumia. The 920 has IPS display ,while 925 has AMOLED screen meaning 925's screen has more saturation helping colours appear brighter and more vivid; this does nicely fit bright and bold with Windows Phone 8 interface, though photographs/web can start to look overly saturated compared to 920 which also has better viewing angle (so said).
