Yes, only for few days temporarily.
Lumia 640 and 640XL are great windows phone overall. The thing I like most about them is their manual camera controls, that even allows manual focusing, shutter speed adjustment and few other advanced controls that I find very useful in many occasions.
640 front camera is just 0.9MP camera and not available here officially, other than that its way better than Lumia 540 in almost every aspect.
Lumia 640XL has Carl Ziess optics lens and the photo quality is excellent, almost like a flagship.
The ONLY problem with them is that they are on Windows platform, other than that i did not face a single issue with them.
But I won't deny that there are some better Android phones available in same price range. @silentassassin1 has 640XL AFAIK.
