Good to handle and btter to use. Meet my needs, No lags superfast Affordable 4G Phone.I just low Lumia and its User Interface compared to Android.
Coming to Lumia 638 its just a masterpiece in middle end devices.
1gb ram with Snapdragon 400 makes it superfast. Sound clarity is good, but not that much of 630. Camera is good.
The only negative we can say is that there is no flash for the rear camera and there is no front cam.
Otherwise this will be super affordable most fav phone for many.
Regarding delivery, what to say - it was just excellent. Ordered around 6pm in the evening, got it delivered on next day morning around 9am.
Delivered in less than 15 hours - In Normal FREE Delivery Option.
Coming to software section Microsoft India has not given Lumia Denim to 638 and says that it will be directly updated to Windows 10. The current software in 638 is Cyan Release(WP8.1)
If any body needs Denim Release(WP8.1 Update 1) just follow these steps.
There’s an easy way to get it through Preview For Developers(PFD) Update.
