Expert Review


The Comio C2 is a phone that is coming from a brand that is just getting started in India. While it may take time for the company to settle and find its sweet spot, the C2 is capable of pushing the company further in a right direction. The build quality is excellent, the display is decent, battery life is fantastic, and the performance is passable. However, we have our own complains, the gaming experience is weak, the cameras are not very impressive, and the lack of fingerprint sensor is a big let down. So, if the mentioned cons don’t bother you much, the Comio C2 is a perfect pick in this price segment. If not you can also have a look at the Redmi 4, Redmi Y1 in this price segment.


Comio is a new brand to enter India with an aim to conquer the budget and mid-range segment. While this may take a fair amount of time, the company, for now, is keeping the market flooded with consistent launches at regular intervals to stay in the news. The budget segment in India especially in the sub Rs. 10,000, price market there is a head-to-head fight going on between brands like Xiaomi, Lenovo, Huawei, Motorola, and others. It takes something out of the ordinary for a new brand like Comio to over-shine them. However, it is too soon to judge how far the company would go in terms of market share and popularity, but we are willing to stay optimistic. Earlier we reviewed the Comio’s S1, and despite its flaws, the phone overall is a good buy for the asking price. Though there is nothing exceptional about the phone, we liked how perfectly it got the basics right.

In our today’s review, we are taking a closer look at the Comio C2 which again looks solid on papers like its predecessors. Either Way is it worth your hard earned money? We review.

The Comio C2 sports a 5-inches HD (1280X720) IPS display and is powered by the MTK6737 clocked at the 1.3GHz Quad-Core processor. There are 2GB RAM and 16GB storage with a microSD card slot for memory expansion. It runs on Android 7.0 Nougat right out of the box. In the camera department, there is an 8-megapixel rear camera with LED flash and an 8MP front camera for selfies and video chats. A 4000mAh battery is on board.

Design & Display:

While we are used to metal unibody designs in the sub Rs. 10,000 segment these days, the Comio C2 is all about plastic. Right from the back panel to the frame running around the four corners, the device is entirely made out of plastic. However, it doesn’t feel cheap in any way. The company is using a non-breakable plastic for the rear panel which is neat. There are very thick bezels on all four corners of the display which become quite boring after using it for quite some time. Moving along to design, there is nothing much to brag about here. It is a regular candy bar shaped phone with slightly rounded edges and curved back panel.

The gold color buttons and rim around the rear camera looks very premium and gives the phone a unique look. The blue and gold combination brings out the looks of it. The back panel to gets a textured design which the company claims is rugged and scratch resistant. We appreciate the tiny details like these which makes the user experience completely pleasant. With 4000mAh battery under the hood, the device isn’t lightweight; it weighs 168 grams which is a decent trade-off for such a massive battery unit.

Moving to placements, above the display, you have the main earpiece, an 8-megapixel front camera, the usual set of sensors. Down below are three capacitive buttons which aren’t backlit making it hard to access them in the dark. On the right side, you find the volume rockers and power button. To the left, there nothing. Flipping the device to the rear, you have an 8MP rear camera, LED flash, Comio branding, and speaker grills. Up top, we just have the 3.5mm audio jack, and on the bottom, you have microUSB port along with a primary microphone. Strip opening the back panel gives you access to SIM and microSD card slots, but the battery isn’t removable. Considering the price and the phones that the Comio C2 is competing with, we still feel the lack of metal body is a letdown.

The Comio C2 sports a 5-inches HD (1280X720) IPS display with no protected glass on top. We would have liked if the company had included a 2.5D curved glass panel as it adds good grip and comfortable in-hand feel. Moving along, since it is an HD panel, colors look vibrant and sharp. There is no pixelation of colors, text, or images when zooming in. Being an IPS panel, the color reproduction is near accurate. The viewing angles are good; we didn’t notice any off-angles or color hue while tilting or viewing the phone from extreme angles. Though the phone sports 5-inches, the odd-looking bezels on all corners gives little room for screen real estate.

The company didn’t include any external display modes like reading or night mode, so you will have to rely on default profiles. There is an auto brightness sensor which auto adjusts the brightness depending on the ambient lighting. However, we found the sensor to be a bit wonky at times, as it doesn’t get as dim as we would expect in dark lighting conditions thus hurting our eyes. This can be an issue with poor software optimization also, but the end of the day it’s there. With no hardened glass on top, there is no extra protection to the display, but the company is offering a free screen protector within the box. This should include the screen from fingerprints and scratches to a certain extent. Overall, the display of the Comio C2 is fine and acceptable.


The Comio C2 is powered by the MTK6737 clocked at the 1.3GHz Quad-Core processor and 2GB of RAM. The performance in general day-to-day usage is good. Apps open up quite fine, and they load a bit slow, but it still acceptable. We wish the company had gone with a Qualcomm Snapdragon chipset since the processing speeds on the Comio C2 feel a bit slow. Though there is no lag, we constantly had to put up with the slower loading and processing speeds. While the MediaTek MTK6737 is a capable chipset, it is too old now to handle updated apps that need a lot of resources to run smoothly.

The U.I is lag free, and the animations never faced any frame drops. The good thing about the performance is that it doesn’t heat up much regardless of how heavy the usage is. Apps like Facebook, Instagram, WhatsApp, Twitter, Chrome run smooth, but you will face slowdowns if you are running them all at once. The 2G RAM is not sufficient enough to handle most usage requirements. The interface becomes laggy and unresponsive even with slight heavy usage.

Moving to gaming, we tried to run medium to high-end titles like Asphalt 8, Nova 3, Modern Combat 5, Subway Surfers, Temple Run 2 and more. Though the medium level games ran fine, we faced issues with high-end titles like Asphalt 8 when graphics are set to high. Moving the graphics to low-level improved the gameplay and is a bit smoother. The biggest let down with the Comio 2 is the lack of a fingerprint sensor. With budget segment inching closer to the mid-range, features like 18:9 aspect ratio and Fingerprint sensors are slowing finding their way. Comio skipping on such essential element is disheartening and is a big deal breaker for us. Overall, the performance of the Comio S2 is acceptable, but not when you compare it with the likes of Xiaomi Redmi 4 and others in this segment.


The Comio C2 features an 8-megapixel rear camera with LED flash and an 8MP front camera for selfies and video chats. Talking about the camera performance, the images shot in good lighting and outdoor conditions turn out fine with ample colors and acceptable details. Though we find the output a bit overexposed, it is still in the passable range. There is autofocus, which is relatively quick even if you move the phone fastly. However, the image processing takes a bit of time to save the photo before you click another one. This will get annoying as you keep using the phone.

The landscape shots are good, so are the macro shots with decent Bokeh effect. The camera interface doesn’t offer much in terms of features, but you can rely on 3rd party shooter for better control over the camera. In the low-light situations, the pictures are washed out and are completely noisy. Despite using the LED flash, the images turned out bad making it look very unnatural. The front 8MP does a better job with selfies. Much like the rear camera, the front also shoots better images in outdoors and bright lighting conditions. The rear camera can record 1080p videos, and the quality of the video is average at best. Overall, the camera isn’t the strong aspect of the Comio C2.


The Comio C2 packs a 4000mAh battery with support for a 5W charging speed. The battery isn’t removable even though the back panel is. The company played it smart by including a massive battery unit on a smartphone that is competing with the undisputed Redmi 4. The battery life is simply amazing. With regular to casual usage, we never had issues pulling it two days straight. The battery never drained faster than usual, and there were no drastic drops even on heavy usage. Since the interface is close to stock, the U.I too didn’t consume battery drastically. Even with slight heavy to mixed usage, we were able to get more than a single day of battery life.

As we said, the company did a brilliant job in optimizing the battery to work well with software and hardware. While it is not as good as the Smartron tphone P with 5000mAh battery, it is as good as the Redmi 4 in this price segment. With the bundled charger, the Comio C2 took close to 3 hours 10 minutes to charge fully from 1% to 100%. Since our testing was with just single SIM installed, the battery results will slightly differ if you are a dual SIM user.

Audio & Video:

The Company did bundle a pair of in-ear style earphones within the box. Though the wire quality is weak, the sound output via them is acceptable. There is no distortion in audio even when the volume levels are maximum. The default audio player was able to play most audio formats. The speaker grills are present on the rear, so the sound gets muffled when it is placed on a flat surface.

The device was able to handle most video formats as well. We never faced issues when playing a 1080p video even with 4G turned on. We didn’t notice any heating or freezing issues while playing videos even with 4G turned on. Overall, the audio and the video experience of the Comio C2 is impressive.

Software & Ui:

The Comio C2 runs on Android 7.0 Nougat with a custom interface on top. Though the interface is custom, it closely resembles stock Android. Like on many phones coming from China, the Comio C2 interface too resembles the iOS style arrangement with all the icons present on the home screen. Customizations in the form of theme store, wallpaper where you can download images or themes to change the U.I the way you like it are still available. You can download 3rd party launchers from Play Store if you like to have the interface look a lot like stock Android. Apart from Google default apps, there are few pre-loaded applications like Freezer which freezes the unused apps to save storage, 360 Anti security Theft which comes very handy when you lose your phone or forget where you placed it, UC Browser, Xender, Clone that comes by default. While few of them are convenient, the rest are unnecessarily taking up our internal space. In terms of customizations, there is a theme store, though it doesn’t have as many themes as we would like, it is still growing which is a good sign. Even if you didn’t like the themes available in the theme store, you could download 3rd party launchers and icon packs to keep things the way you want.

There is 2GB of RAM of which around 900MB is free on first boot. Though it is not a stock Android, the RAM usage is very low, and the memory management is also on the bright side. We didn’t notice any apps running out of memory at any point in time. The U.I isn’t laggy, and the animations render smooth. We were able to do casual to moderate multitasking also without any stutters. You won’t notice any significant lag in the interface unless you are running more number of an app than the phone can actually handle. Overall, the software experience of the C2 is decent. Considering the price, we wouldn’t keep our hopes on the Android Oreo update anytime soon.
