In case anyone wants to know the SAR values for this phone (according to the manual that comes with it).
These are Maximum Sar Values (meaning that its the highest it could be, many times its lower if you have a strong signal)

Lumia 730 having great display near to retina type display .Capable rear camera front camera is just a great but not as good as Xperia C3,and good battery backup.Lumia 640 Having nice display Not as good as 730,solid battery backup,good in camera.640 XL is again good display not like 730 & decent camera rear & front but not in dark in dark noise level is high and its visible too. 640 XL slightly bigger 5.7" 730 4.7" is just a perfect size easy to operate with single hand.Battery backup is at par simply superb.All three Lumia Smartphones 730 ,640 & 640 XL having great sunlight readability.
Overall all three sets have their own advavantage & disadvantages

This is my fourth Windows Phone. I have been thinking that windows phone have a more systematic hierarchy. The improved display on Lumia 640 is attractive.

cheers ! :)
I use 535 & 640. . Both are cheaper than I Phone but fast like I Phone & androids. The best phones I ever use. Perfect for me. Very much usefull apps. Very clear to understand for all win. users. No problems.....
The hardware is very fine, but before buying one make sure that you'll be able to go without the google apps, especially if you're coming from an Android device. The tiles system is also very nice, and it looks much more expensive than it really is.
