A few months ago, Microsoft introduced the Lumia 535, a budget Windows Phone device and the first that carried the Microsoft branding after the transition from Nokia. Since then, there have been a slew of budget Lumia devices, several arriving in emerging markets like India before traditional Microsoft markets like the US or UK. The Lumia 540 is an improvement over the Lumia 535 with a better display and an improved camera, but it comes at a time where the boundaries between the Lumia range of devices are blurring and the feature-set and pricing is overlapping between different devices. The Lumia 640 that launched a few weeks ago sells at a similar price to the Lumia 540 but features better internals, although with a limited front camera. The Lumia 540 was launched in India earlier this week, and here are my first impressions of the latest budget smartphone from Microsoft.
