Micromax Bolt D321 Review


Micromax which is known for providing both budget friendly phones and high-end phones has yet another installment in the former sector. With the introduction of Micromax Volt D321 on its official website followed its release which happened in late February 2015, it is now available on all Indian e-commerce websites. The earlier models of Bolt series were not so successful so by revamping the design and adding additional features, it is now in the market making up for all the loss caused by the previous models. The Bolt D321 has some exciting features for a 5,000 rupees phone. Let’s look at some of the features.

Design and looks:

The Micromax team has put in enough effort in creating a sleek phone. It has rounded corners and is available in two colors, white and blue. The edges are also slightly curved which gives it a old-fashioned basic phone look. The phone is not heavy and is fits rightly in your hands.

Display Screen:

Bigger screen is the main selling point of this model. The phone offers a 5 inch FWVGA display screen with 16M color depth accompanied by 480×854 pixels resolution. Many phones in the same range offer less than 5 inches of display screen so a larger screen could actually attract more buyers, but with resolution compromised.

Battery Backup Life:

It runs on an 1800 mAh battery which is capable of providing 300 hours of standby time. It will last for 7 hours on maximum usage. The battery is just enough for the basic features that the phone offers.

Dual-SIM Support:

You can accommodate two SIM in this handset without having to sacrifice your extra storage space like in the other models.

Removable battery:

Most of the Micromax handsets these days do not come with a removable battery as they are enclosed in a Unibody metal frame. This particular model has the option of removing the battery which is preferred by many. Many of the phones these days are shifting towards the global change of introducing metal body frames which restrict the users from removing the battery. It created uproar in the beginning. It is nice to note that Micromax still produces phones with replaced and removable batteries.


The processor built in for this is a 1.3 GHz dual core processor. It will slow down the device eventually. A better processor could put this model well ahead of its competitors.

Quick start feature:

This unique feature allows you to access apps from your lock screen directly. You can customize the apps given and choose your favorite apps to be displayed on the lock screen. This is a new feature that Micromax has come up with and it is getting positive reviews from the users.

Operating system:

The Bolt D321 operates on Android KitKat 4.4.2. It is not upgradable to Lollipop. With most of the makers now selling the Lollipop OS in this price range, Micromax might face a huge challenge due to not providing this option.

Memory Storage:

An internal memory of 4GB is provided which is expandable up to 32 GB. It comes with pre-installed apps and lot of bloatware. Apps like Truecaller, MAD and Opera Mini all come pre-installed in the device. The 4 GB internal memory is fair for a phone in this price range but with many such pre-installed apps occupying so much of the space, the 4GB internal memory fails to serve the purpose.


A 512 MB RAM is another huge disadvantage in this model. The 512 MB RAM will not be sufficient to run the highly sharp display screen when apps are loaded, in the long run.

Camera Features:

The phone comes with a standard 5MP primary camera and 0.3 MP secondary camera. The quality of images taken in the 5MP primary camera is average. Videos can be recorded with playback options. The quality of the images and the videos are not very good. The secondary camera could have been given a little importance, with the popularity of selfies growing each day, even a new user might look forward to taking good picture and it is quite impossible to click even reasonable pictures with a 0.3MP secondary camera.


Light sensor, proximity sensor, gyroscope and accelerometer are some the sensors that are provided in the handset, as expected off an average ranged smart phone.


It supports all the basic connectivity needs like 3G and Wi-Fi while file sharing is possible through Bluetooth and USB connections. It does not support 4G.

Phone in this price range do not even offer 3G connectivity, so it will be a selling point for this phone to offer 3G connectivity.


It represents its predecessor Bolt A82 in most of the features. Why Micromax would produce two phones with similar specifications is still something to ponder on. It is not a phone one would buy if you are looking for a performance based phone. The RAM and processor are the only disappointing features in this phone otherwise; it has great features for a 5000 rupees budget. It especially calls out to all the new smart phone users who do not want to spend much on their first Smartphone. The 5MP primary camera and other software features suggest that it is indeed a good buy. The other phones in the same price range do not offer as much as a 3 MP primary camera. Nevertheless, the compromise on performance is not acceptable. You can use the phone for basic apps but not for heaving gaming. The sharp and clear display is one thing that might draw and attract many buyers.

Micromax still does have competition from other brands like Karbonn which also produce similar budget friendly phones with similar features. Bolt D321 might fail as the competition is getting higher.

One more thing we can observe with the recent releases is that, Micromax is trying to create a trademark style by modifying Android features, slowly. We might soon lose out the pure-android experience that the earlier models used to offer. Let’s wait and see if this will be a welcoming change.
