Spice CSL launched two Android smartphones with Dual SIM Dual Standby capability, Switch MARS Mi450 (RM699) and Switch PLUTO Mi406 (RM599) in last February. I received a Mi450 loan unit for review. Read on to find out if it worth your money or not.

What’s in the box?

At the first glance, Mi450 looks like HTC One X. The design is sleek and has a curved plastic body with round corners, 2–3 millimeter (mm) thicker than iPhone 4S. The rear cover is a piece of thin plastic.

I like the Mi450 phone size. I think 4.5-inch is perfect for my hand size. The phone is not heavy, and curved body make it nice to be held in your hand.

4 capacitive buttons (home, menu, back, search) located at the bottom of the 4.5-inch display. At the top, you get 3.5mm audio jack and power button.

The rear camera is at the top center and LED flash located under it. Bottom of the back is speaker. Micro USB port is located at the side, volume control buttons at the other side.


CSL Switch MARS Mi450 is a 4.5-inch (960×540 pixels) display smartphone running Android 4.0 (Ice Cream Sandwich).

It is powered by Qualcomm Snapdragon S4 1.2GHz dual core CPU, with 512MB RAM and 4GB ROM. Mi450 supports Micro SD up to 32GB. The smartphone is equipped with dual camera: 5MP auto focus with LED flash rear camera and VGA front camera.

Mi450 supports Dual SIM Dual Standby (more on this later), WiFi 802.11b/g, WiFi Direct, DLNA, Bluetooth, A-GPS. Removable battery’s capacity is 1800 mAh, standby time up to 4 days as claimed.

Personally, I dislike Android phone with many pre-installed apps because they are mostly useless and affecting the system performance. Mi450 doesn’t have the problem. What you get is an Android smartphone with a clean and simple theme with cute rounded corners app icons.

TouchPal Input V5 is pre-installed to help you type faster and better on touchscreen phone. S-unno VoIP app is also pre-installed allows you to make cheap International calls/messaging (20 mins credit included in the box).


The display’s colour is good, text is clear but too easy to leave prints on the glass. The small speaker at the back is surprising loud. When you hold the phone, the sound from the speaker actually bounces back to you you through your palm.

Mi450 benchmark results
Mi450 benchmark results

According to AnTuTu Benchmark, S CSL Switch MARS Mi450 received 6,615 points. Slightly lower than Samsung Galaxy Nexus, which is also powered by dual-core 1.2GHz CPU. In Quadrant benchmark, Mi450 scored higher than Samsung Galaxy Nexus, received 2,652 points. For your reference, the latest high-end Android smartphones are scoring over 10,000 in AnTuTu Benchmark.

Though not a high-end smartphone, Mi450 does not have problems handling most of the mobile games in the market. I tested Angry Birds, Death Dome (3D), Temple Run (3D) and the performance is good. No lag, no crash. It took some time to load the games, though.

Dual SIM Dual Standby

CSL Mi450 supports Dual SIM Dual Standby, a feature you won’t get in high-end smartphone. Dual SIM Dual Standby is useful that you can use two phone numbers (example: Home and Work) in one phone.

There’s two SIM slots under the rear cover. Only one support 3G (WCDMA) and the other is 2G (GSM) only. Make sure you have insert the correct SIM card.

Installing SIM cards is easy, simply remove the battery pack and slot in the SIMs. No tool needed.

Under Android Settings, you can turn on/off each SIM. There’s a small SIM icon in SMS message to indicate the message was sent to which SIM number. You can select which SIM to be used in Calls and SMS.

Nothing “WOW” about Mi450 5MP camera. The control is basic — touch to focus, tap to shoot. Auto focusing delay is about 1 second, and camera capture delay is 0.5 to 1 second. No burst shots.

I found the photos are over contrast and colour are a bit off. Check out the sample photos captured by Mi450 below. Click to enlarge for full-size photos. All are not edited.

LiewCF’s Buying Advice

Comparing to other budget smartphones in the market, S CSL Switch MARS Mi450 has bigger display and better body design that runs Android 4.0 (latest version is 4.2 Jelly Bean).

Android 4.0 (Ice Cream Sandwich a.k.a. ICS) is the latest version of the mobile operating system. Some previous Android devices get the update but, unfortunately, some don’t get update.

DigitalTrends created a list of Android smartphone or tablet that get ICS update. If your device is not in the list then most probably it won’t get ICS update, too bad.
