Lava Z40 (Glossy Black, 1 GB RAM/8 GB)

About the Phone

Despite coming at a low price, Lava Z40 looks quite well-crafted. It comes with the following pros and cons:



  • Lava Z40 is sleek and well-designed to fit perfectly in your hand without digging in your palms.
  • It has a bright display that is quite legible even when taken outside.
  • The battery of Lava Z40 is quite adequate for the phone and keeps the juice for about a day with light use.
  • It has the Android Go software which efficiently utilises the phone despite its low specifications and provides an optimal service.


  • The Lava Z40 has a meagre 4-inch display which is very low in modern times.
  • The phone has a weak processor which is paired with a meagre 1GB RAM which makes multitasking laggy and can freeze the phone frequently.
  • The cameras fitted on the Lava Z40 is inferior and does not click decent shots. The shots generally have washed-out colours.


The Lava Z40 is a low-priced phone, but that cannot be the excuse for producing an inferior model. It is not a recommended phone even for people with a tight budget. In this respect, the Panasonic P95 can be a better phone to go for.

One of the first things with which Lava Z40 attracts the audience is its decent design and price. With a price of Rs. 3,499, the phone is an entry-level model targeted to the people with a tight budget.


However, Lava Z40 is a below-average phone. The display of the phone is very dated and almost recalls the beginning of the smartphone era. Plus, the performance or battery is not up to the mark. There are much better phones present in the market which can be opted for, at a similar range or with a slight boost in the budget.

Lava Z40 has a sleek body with rounded edges that make it sit comfortably on your palms. The phone does not dig into the palms that easily. The smooth cover makes it easy to hold and does not make it slippery either. The phone design makes it quite rigid. However, it is not exceptional in its design and may not be able to draw your eyes if placed with other budget phones.

The phone comes with a 4-inch display and a 16:9 aspect ratio. The 4-inch screen looks very dated because of its length, since most budget phones, even at a low price, reach 5-inch. The display has a Corning Gorilla Glass so that there are no cracks or scratches. The screen is ok. The colours are not quite sharp and appear a bit washed out. Indoors, the display is legible and performs well, even at around 75% brightness. Outdoors, bright sunlight can hamper the display and bring it down to an illegible degree. The display is not the most robust feature of this phone.

The Lava Z40 comes with a Unisoc SC9832E processor clocked at 1.4 GHz. It comes twinned with a 1 GB RAM. The RAM is quite low, and so, multitasking is not an option. If you start running many apps on this phone, it can freeze. High-end games like PUBG will not run on this phone, and casual games can end up lagging at times. Plus, the small display won’t be able to give you an immersive experience.


One of the main features of the phone is the Android Go software, optimised for low performing phones. It has the Lite editions of Google Maps, Youtube Go, etc., all geared for low performance. Plus, you have the Data Saver feature to manage your data consumption. All in all, the software is fluid for this phone.

Lava Z40 comes with a single 2MP rear camera with LED flash. The sensor is deficient, and it shows in the shots. The images do not appear well despite the low-screen size of the phone. There is a bit of grain that gets captured on the photos. Plus, the photos look washed out. The only saving grace is the flash, which makes the photos look discernible even in low light situations. The phone also has a small 2MP selfie camera which does not capture detailed selfies and is not recommended even for social media use.

Lava Z40 comes with a 2250 mAh battery. It is a very small battery, but since it powers a poor display, it can still chug on for an entire day with light use. However, there is no fast charging, and the phone can take 2nhours to get to full charge.

The Lava Z40 is an inferior phone. It comes with a mediocre camera, below-average performance and low-level, dated display. The only good thing about the phone is the software, though that has been put on the phone because of its poor hardware. Overall, it is not a recommended model. There are far better phones present in the market which will serve your budget phone dream more efficiently, performance, and look-wise.
