LetsDnD Opinion for Microsoft Lumia 640 XL LTE Dual Sim Phone

Mid-range handsets seem to be getting huge in size and the Lumia 640 XL is definitely one of the biggest. Measuring 157.9 x 81.5 x 9mm, weighs 171g. It’s available in five color options; Microsoft phones are known for their vibrant colors so phone colors are white gloss, white matt, cyan, orange and black.

Keeping eye on its size, the 640 XL is comfortable to hold and doesn’t feel chunky at all. The overall design of the phone is minimalistic with the body of the phone made from a smooth tough plastic. Gentle curves rise on the rear of the cover to house the camera unit and 3.5mm audio jack, while a small incision has been made for the rear loud speaker.

Its Only Microsoft’s name, brand and logo associated with it which may or may not help Microsoft that we cannot say.

The face of the phone is typically Nokia Lumia, all black with three familiar touch keys, search, Windows Home and Back all positioned at the base of the screen. Corners of this new phone are better rounded than the older models.

Corning Gorilla Glass 3 protects the phone’s 1280 x 720 resolution IPS LCD screen from accidents, which is good to see on a low-end device. The plastic back cover is removable and inside you’ll find a large replaceable 3,000mAh capacity battery, which should give you about two days of regular use or a stated 37 days of standby. There’s also a microSD expansion slot for up to 128GB of additional storage in case the phone’s built-in 8GB memory isn’t quite enough.

Icons are sharp on the phone and the touch screen is highly responsive. Being packaged with the Lumia Denim update, the 640 XL has some tidy features out of the box including one-swipe action centre and Word Flow. Word Flow is like the Android swipe to type keyboard function. You just trail your finger over the keyboard to spell the word. It’s a quick solution and works well on the large 640 XL screen.

Microsoft’s core Office apps; Word, Excel, PowerPoint, Outlook and OneNote are pre-installed on the 640 XL, which is great for productivity. Additionally, the phone comes with a free one-year subscription to Office 365 Personal with one terabyte of cloud storage and 60 minutes of Skype calling per month.

We are expecting to see the Windows 10 update come to the 640 XL which should improve its feature set further.

A 13-megapixel camera with Zeiss optics on the rear and 5-megapixel wide-angle front-facing cameras take care of image and video capturing needs. It’s a decent deal if you are looking for a mid-range handset.

One thing that does set this camera apart from the pack is that the Lumia Camera app has manual controls as standard, which is a great plus point for people who want to get more out of their mobile photography. It has high shutter speed and ISO control.

Powering the Lumia 640 XL is a quad-core 1.2GHz Snapdragon 400 chipset, with 1GB RAM, which makes for swift switching between applications. Although gaming options in the Lumia store are somewhat limited.

We are looking forward for its customer reviews and experiences as the Microsoft devices are well known for its build quality and unique Microsoft apps and it featured and packaged with Microsoft’s very own OS Windows Phone 8.1 and many more…
