Lumia 830 or Lumia 640 XL

[ermeru]

Lumia 830 strengths:

• more internal storage (both take SD cards but internal storage is faster and more reliable)
• display with higher pixel density
• dedicated camera button
• OIS (for better low-light pictures and less jerky video)
• stereo/surround sound recording
• gyroscope (I've personally had a lot of trouble with panoramic photos on gyroscope-less phones)
• built-in wireless charging
• body design and materials
• dual-band wifi

Lumia 640XL strengths:

• larger battery (presumably longer-lasting based on similar specs)
• dual-sim variant available
• front camera resolution
• rear camera resolution (megapixels are no guarantee of quality - e.g. the iPhone 6 and Nexus 4 both have 8mp cameras but most people would say the iPhone takes far better photos)

There's got to be additional cost-cutting somewhere. My bet is on features like an oleophobic screen coating, multiple mics, the quality of the ClearBlack display, etc. that historically are absent from or not good in the 6XX range.

Your personal preference:

• larger (640XL) vs. smaller (830) screen size
• on-screen buttons (640XL) vs. capacitive (830)

U know the Lumia 535 and it's have 5mp rear and front cam. U think both of them take a same quality of the picture ? Maybe front cam is worse than rear

Woah woah woah! YOu forgot the Lumia 520!

All PureView phones have a camera button but not all phones with a camera button have PureView.

What if i look other 5MP Lumia cameras like Lumia 535 both of them same lens or same thing ? I mean same quality of XL front cam ?

Front cameras are almost always worse than rear cameras. For instance, most front cameras lack autofocus and flash, have smaller sensors, worse lenses and so on.

Ideas changing like speed light.. Why did you say that man why.. I was happy with this rear=front lie. So what now.. Should i buy XL ? Worth that ?

Why not wait a week or two? I'm sure there will be a review soon.
