90Hz refresh rate on a budget device

Symphony Mobile is one of the pioneering phone manufacturing brands in Bangladesh. The company started its journey in 2008 by renaming Chinese handsets. Symphony ventured into the Android smartphone market in 2012. Since 2018, the company has been assembling the devices right here in Bangladesh.

Over its illustrious decade-long history in the industry, the company has continued to deliver affordable smartphones to the masses. In this commitment, the company has launched its new offer, the Symphony Z47on November 15, 2022. Here’s our in-depth take on the device.

Symphony Z47 Key Features

Before going into details, it is important to note that as a local company, Symphony has always undervalued the competition in terms of price. The story is also somewhat true for the Z47.

Design and build quality

Moving on to the build quality of the display, users will get an all-plastic build device with a glass front. The design element is in line with other Symphony launches. With its square edges, square camera housing and chunky teardrop-notched display, the device is a typical Symphony in every way. However, that’s not necessarily a bad thing.

Even though the device is made of plastic, it is very durable in the hand. The back part is glossy plastic, giving it a distinct glass look, while making it a fingerprint magnet.

Port and button choices are all standard for a budget smartphone. However, the volume rocker seemed to be a bit higher than it should be. Other than that, the Type-C port, headphone jack, and dual SIM slot with micro SDXC support make a complete package.

Overall, the design can be described as generic at best. But the build quality is quite good for the price at which it is offered. Now let’s see some of its other features.

A first glance at the Z47’s 6.6-inch screen won’t excite any excitement. Thick bezels and an INCELL HD+ IPS LCD screen might seem decent for its price. It sports a resolution of 720 by 1600 pixels.

What makes this display a clear winner in its class is the 90Hz refresh rate. In a sub-12K budget, Symphony has somehow brought a 90Hz refresh rate to the masses. This is a game-changer, considering how smooth the operating system is and general usage. This allows for a pleasant experience of scrolling through things and provides a livelier feel.

The screen’s color metrics are also satisfactory. Colors looked crisp with a hint of warm tone. There is no visible color change at the corners. There’s no dedicated HBM on the Z47, as expected, but the screen does get relatively bright in outdoor use.

The camera

Symphony also made notable changes to the camera department. From the outside, the device comes with three sensors on the back. But the 52 MP main sensor does all the work. Obviously, the sensors that come with it are just for marketing purposes, as Symphony hasn’t provided detailed specs for them.

But the main rear camera integrated into the Samsung sensor is not left out. In our test, it was able to take fairly accurate and color-correct photos outdoors. The sensor can capture high detail and preserve dynamic range. The only gripe with outdoor shots is that the contrast could have been a bit better, as sometimes images look soft even in well-lit environments.

The camera also faces similar issues in a darker environment. For a 52MP shooter, low-light photos were a bit disappointing. The exhibit did well at times, but also failed miserably at others.

The front camera is your generic 8 MP shooter. It’s good enough for casual casual selfies.

Camera features include Burst, AI, HDR, Portrait Mode, Night Mode, Enhance lowlight photo, Slow-Motion, Panorama, Pro mode, Qr Code, Audio Note, Face beauty, Watermark and Time lapse.

Videography is limited to 1080P at 30 fps. It’s not exactly good, given that there are no external or internal stabilization options.

In summary, the camera experience differs from the display experience, but the results are passable for casual shooting and social media posting.

Processor and performance

The Symphony Z47 is equipped with a Unisoc Tiger T606 processor. The choice of Unisoc is quite understandable as they have become the go-to option for ultra-budget smartphones.

The processor is a 12 nm based on a cortex-A75 chip. Users will also get a 650 MHz GPU along with the CPU.

So how does it work overall? While the processing power isn’t exactly promising, it works quite well on a day-to-day basis. If you use this device for media consumption and casual browsing, the device will have no problem keeping up.

We even tried a few high-end game titles like Asphalt 9 and COD, and needless to say, they were nearly unplayable at the highest graphics settings. If you reduce it to medium or low, you might be able to try them. Even then, the weak GPU unit causes the device to heat up considerably.

The saving grace for the processor is the high refresh rate display. It evens out lags and frame drops and provides a consistent experience.

It has 4GB of RAM combined with 64GB of internal storage expandable up to 256GB.

Battery and charging time

The Symphony Z47 is equipped with a 5030 mAh battery. The battery can last about 6-8 hours of continuous use. Unfortunately, the device does not have fast charging, so users have to settle for long hours of charging.

Symphony Z47 price in Bangladesh

The Symphony Z47 is available in a single configuration of a 4/64 GB variant. The price of the device is BDT 11,499 excluding VAT.


Symphony has always been one of the most prominent brands in the ultra-budget smartphone market in Bangladesh. Over the years, the market has been saturated with low prices with repetitive design and specifications. So it’s refreshing to see Symphony making changes with its high refresh rate display.

As for the camera, the 52 MP sensor sounds good on paper but fails to deliver in real-world use. The rest of the specs are on par with the price.

There are maybe a few minor aspects that could be improved, but it’s mostly a cost-effective device, especially when you consider the price. To conclude, who is it for? The Z47 is best suited for people looking for a practical smartphone with an affordable budget. As a daily driver, the Symphony Z47 can be an excellent choice in its price category.
