I love my Lumia 1520 so much, and am so glad that I took the plunge to get one back at the start of the summer, considering that it was not sold in Canada.
I was thinking about it lately, that the Lumia 1520 just looks so good. I love the design, I love the 6" display (there is no going back), I was always an AMOLED guy, but the 1520's LCD display is simply fantastic. I must also mention the excellent battery life. The only area with room for improvement would be low light performance with the f2.4 aperature lens. If I could pop-in a 950 series camera, the Lumia 1520 would be perfect.
I was really looking forward to what we call the Lumia 950 XL, but really, from the way my L1520 performs, I don't need more ram, or a snapdragon 810 processor. If phones continue just offering more of the same with yearly hardware upgrades that don't completely change the game, I'm going to ride out my 1520 for as long as it works - or until phones take a quantum leap ahead.
Overall, it's a phone! My 1520 is perfect at being a communications device, captures excellent images, brilliant video with Nokia's HAAC microphones for the best audio capture around. In many ways, the 950 series would not change my day to day experience for the better.
I recently bought a mirrorless camera, so the drive for me to have the absolute best camera in a cell phone is no longer what it once was. Plus, the super wide angle of cell phone camera lenses left me frustrated in some video capture situations.
Long live the Lumia 1520!
