It is the mini version of Lumia 640XL but with the lower MP front camera. The lumia denim UI is very smooth seem less and fluid, and the settings customization is done well. The display looks very beautiful. The colors are very bright and with the given resolution it comes with a very good clarity. The viewing angles are very good and you can watch it from steep angles.

Microsoft Lumia 640 Dual SIM Gaming

The theme colors given are extraordinary. The video play back quality is also good but the sound from stereo speakers and ear phone quality is loud but with bass and all it is average. The camera has extraordinary capturing technology especially in day light but coming to the clarity of pictures captured at low light seems dull and pretty low. The front camera is also good and useful for selfies with average details. You can lay all types of games pretty well with out any major hiccups.

Microsoft Lumia 640 Dual SIM Camera

I installed games like Asphalt 8 it is playable in this device there is slight glitching but not bearable. Graghic games like Tekkan also ran well. The Antutu bench mark score is 11916 points which is below average and the base mark OS 2 is 461, and Base mark X it got a score of 4814 which is very low. The battery gives enough space. Talking about the bench mark scores there are not pretty comparable with android smart phones because of the different5 OS. I say the overall performance is above average. No hangings have been noticed.


If you are done with using android and old nokia mobiles now buy Lumia 640 with out doubt, it got the OS from Windows and has been customized with improved performance. It comes with a price tag of Rs9000/-. Forget lagging time in your device with Microsoft Lumia 640 Dual SIM.
