Smartphone review Vivo Y91 (Mediatek)

It's too early to talk about the popularity of Vivo in Russia, but many people know the VVK company, which produces various kinds of equipment. What's the connection here? It's simple: Vivo is a subsidiary of VVK, as well as two other more mainstream brands (OnePlus and Oppo).

Vivo did not make it to the conquest of the western market, but they gained steady popularity in the Middle Kingdom and are already in the ratings (in the top five) of the largest suppliers of smart phones in the world.

In 2018, Vivo successfully participated as a sponsor in the Russian Football Championship, thereby making a profitable advertisement for itself.

Vivo does not strive to be the first in the sales of its smartphones in the market, but maintains its identity and quality. Most of all, the devices of this manufacturer will impress photography enthusiasts.

All smartphones of the manufacturer are divided into several lines:

• X - these are expensive devices with flagship "stuffing" inside;
• V - middle tier with good equipment inside, but with prices significantly lower than premium X representatives;
• Y is a budget segment with affordable prices and good quality.

In January 2019, a new brainchild from Vivo appeared, bearing the marking of a budget device with the name Vivo Y91.

Smartphone design and specifications

The appearance of the device has nothing outstanding. This is a typical budget phone, fully in keeping with the traditions of its manufacturer.

The comfortable size 155.1 * 75.1 * 8.3 mm and the harmonious weight ratio of 163.5 g will allow the user to easily use the device for any purpose: from conversations to flying in the online space. This size is convenient as a camera for those who like to capture everything around them.

The case is made of high-quality plastic with an original gradient color, which is available in two colors: Starry Black and Ocean Blue. Shades smoothly pass from top to bottom, changing from dark to light. The brightness and uniqueness are very pleasing, the characteristic departure of Vivo from the classics attracts buyers.

The bezels are very thin, so the entire front panel is made up of the screen. A teardrop notch at the top provides space for the front camera and related sensors.

The back panel is just the main carrier of color. The upper left corner on the "back" is a legitimate and already traditional place for a dual main camera with a flash. In the center there is a fingerprint scanner.

The right side - on / off and volume, left - slots for mini SIM cards and flash drives for additional memory.

In general, the appearance of the smartphone has nothing outstanding, everything corresponds to the budget line.

• Comfortable size and weight;
• Thin frames that do not create discomfort to use;
• Original gradient coloring of unusual shades

• Plastic case;
• The choice of colors could be wider.

Device platform and memory capabilities

The manufacturer took care of a quality update to its budget line and equipped the Vivo Y91 smartphone with the new control platform from MediaTek - MediaTek Helio P22, which is characterized by the highest energy efficiency and performance. It also enables HD + resolution with an acceptable aspect ratio, providing a balance between sharpness and energy efficiency. Here the successful connection of the IMG PowerVR GE8320 processor, responsible for the graphics, and the powerful eight-core ARM Cortex-A53 processor works. A distinctive feature of this chipset is its intelligent capabilities (AI): a well-chosen set of tools allows the use of such features as face recognition, bokeh effects in photos, creating albums using smart albums and much more.

Another MediaTek CorePilot technology provides planned power consumption, temperature control and UX monitoring by evenly distributing across cores and matching harmonious frequency and voltage. At the same time, the performance of the device is consistent with the energy consumption, which creates additional comfort for the user.

Memory

The operating memory of the smartphone is 3 GB, which is more than enough for the processors used by the manufacturer. A sufficient amount of operating system also guarantees the speed of the device without freezing and braking.

The built-in memory (64 GB) is sufficient both for work and for all kinds of entertainment applications, but, if necessary, the deficiency can be filled with a memory card, which can be up to 256 GB.

• The platform used allows you to expand the capabilities of a budget segment smartphone;
• "Cooperation" of IMG PowerVR GE8320 and ARM Cortex-A53 processors provides image quality complete with economical consumption of device power resources;
• Extended and updated AI (artificial intelligence) capabilities;
• Acceptable amount of RAM and built-in memory, which allows the smartphone to maintain high performance while performing the necessary operations;
• Expanding the internal memory up to 256 GB ensures that the phone can be used for any purpose (work, entertainment, etc.)

• Due to the impossibility of a complete test, no cons were found.

Vivo Y91 camera parameters and capabilities

The device has in its arsenal a single 8 MP front camera and a dual rear camera with 13 MP, f / 2.2, PDAF and 2 MP, f / 2.4 parameters.The selfie camera is traditionally located at the top of the bezel in a fairly neat teardrop notch.

Thanks to the high-quality filling of MediaTek Helio P22, the smartphone has acquired updated photo and video capabilities. The MediaTek Imagiq package in MediaTek Helio P22 supports a new hardware depth engine. MediaTek's Electronic Image Stabilization (EIS) system is complemented by a new Rolling Shutter Compensation (RSC) mechanism that combines, successfully softens distorted ("jelly") video when capturing fast action or panning.

The cameras feature incredible low-light performance, multi-frame noise reduction and clear image magnification technology. In addition, MediaTek's Imagiq capture package includes enhancements that automatically minimize overlap, graininess, and provide methods for correcting defects or distortions.

Focusing is lightning fast and requires no effort from the user. Macro shots are almost professional quality.

The intelligence of the cameras has found certain improvements and improvements. This applies to face recognition (Face Unlock), the function of "smart photo albums", bokeh for the main and front cameras and much more.

Thanks to the use of these technologies, the MediaTek Helio P22 chipset allows cameras to capture even the smallest details, create exciting effects, both in photography and in video, at any time of the day when the user wants it.
