Symphony Z40 Review:


  • 76.6 x 165 x 8.9mm, 193.5 gm
  • Plastic back/frame, glass front
  • Corrugated finish at the back

Symphony Z40 is available in three colors: Dazzling Blue, Delightful Green, and Jolly Blue. Its body and frame are both made out of plastic.

Also, the rear panel is corrugated with a sun ray-like pattern. It is divided into two unequal parts by a line running behind the camera bump. The back also houses the physical fingerprint scanner, whose speed is in line with what we get on devices of this price point.

Similarly, the power and volume buttons are on the right side, while a dedicated Google Assistant button resides on the opposite frame. The top frame is clean, and most of the ports are at the bottom. All in all, the Symphony Z40 is like most other budget phones out there in terms of its design. Its radiating design and relatively bulky form factor are reminiscent of Xiaomi’s Redmi lineup of entry-level phones.


  • 6.55-inches HD+ IPS LCD panel
  • 60Hz, 268 PPI, Widevine L3

Moving on, Symphony Z40 features a 6.55-inch HD+ display with 1600 x 720 pixels. Despite the lower resolution, the contents look quite sharp here. In addition, Z40’s color reproduction and viewing angle are fine. On the other hand, it thoroughly struggles with outdoor visibility. But that is to be expected with such budget phones.


  • Triple camera setup at the back
  • (13MP primary, 5MP ultrawide, 2MP portrait)
  • 13MP selfie camera (punch-hole cutout)

The rectangular camera bump at the back of the phone has enough room for three camera sensors, the first of which is a 13MP primary camera accompanying with a 5MP ultra-wide and a 2MP depth sensor.


Symphony Z40 features a Helio G35 2.3 GHz Octa Core game enhancement processor.

Operating System

Symphony Z40 features android 10 with dedicated Google assistant key.

Battery and Audio

  • 5000mAh battery with 10W charging
  • Single speaker, 3.5mm headphone jack

Moving on, Symphony Z40 features a massive 5,000mAh battery which charges over a Type-C port. A 10W charger is included in the box too. On average, the phone provided around 5 hours of screen-on time during my usage. The onboard charger takes an excess of 3 hours to juice it up from 0 to 100%.For audio, the phone has a bottom-firing single speaker. It can get loud enough but does not stand out much. There’s also a 3.5mm headphone jack for wired connection.

Tech Byte’s Final Verdict

At the end of the day, Symphony Z40 is quite a catch if you want to impress your friend circle with the next big thing providing you the experience of a durable and smooth tablet-sized screen and a typical smartphone that can fit in your pocket. Moreover, this might be the right choice for those who like multitasking. Nevertheless, this device can’t be your go-to camera in the form of a smartphone as there are several flagship smartphones out there in the lower price range that can outperform its cameras.
