Micromax Canvas A1

 

The Micromax Canvas A1 and the Spice Dream Uno also come with a notification LED next to the ear piece. While it's hard to distinguish between the three smartphones from the front, the differences at the back are a little bit more pronounced. For starters, there's prominent branding of each brand at the back, and Micromax comes out looking the worst thanks to a rather tacky looking company logo. There's Android One branding towards the bottom on all three phones, just above the speaker grille.

The top has a 5-megapixel rear shooter and LED flash, with Micromax and Karbonn opting for integrated circular and rectangular modules respectively, while Spice has gone with distinct

and flash modules. All three models are made out of decent quality plastic that doesn't feel cheap, and each has a slightly different feel - which one you prefer at the end of the day is going to be down to personal taste. There's not much to choose between the three smartphones in terms of physical dimensions either. At 136 grams, the Micromax is rated 2 grams lighter than the other two, but the difference isn't noticeable while holding the smartphones.Though the three smartphones are rated identical in terms of specifications, each display is calibrated a little differently. The Spice Dream Uno appears more vibrant in terms of colours, but the other two displays are more natural and offer a more accurate representation of the objects when compared to real world.

Camera

In terms of image quality, there's nothing to choose between the three smartphones, with the 5-megapixel rear and the 2.4-megapixel front shooters capable of clicking decent pictures, though the resulting images lack detail. That's not entirely unexpected given the price of the smartphones.
Android One smartphones ship with the recently unveiled Google Camera app that comes with features like Lens Blue, Panorama, Photos Sphere, Timer, and a grid to help you align the subjects in your photos. You can also change the aspect ratio and quality (size in megapixels) of your images. While the phones don't come with a dedicated camera button, you can use the volume up or down button as the shutter.
The front camera supports 720p video, while the rear camera comes with support for 1080p full-HD video. It's worth pointing out that before clicking any pictures, you'll need to insert a microSD card, as the app does not support saving pictures or video to the internal storage of the phone.

Software

The three phones come with Android 4.4.4 out-of-the-box and the fact that Google is in control is evident from the home screen itself. Apart from the dialler and messaging apps, the two other apps on the home screen are Chrome and Google Camera. 

Performance and battery life

All three smartphones are powered by the identical MediaTek MT6582 SoC with a quad-core processor clocked at 1.3GHz. They come with 1GB RAM, a bit of luxury - though not exactly unheard of - at this price bracket. Of the 4GB internal storage, 2.03GB is accessible to users on the Spice phone, while 2.07GB is available on the other two. Thanks to the decent specifications and lack of UI-related bloat, these smartphones excel at day to day activities and basic multi-tasking.
You'll have no problems with casual games like Temple Run 2 and even more intensive titles like Asphalt 8 run fine, though you may experience occasional frame drops.
