BLU F91 is a beautiful device that was officially announced in April 2022. It adopts a modern design and includes multiple great features that can be used by all users.

The BLU F91 is also known as the device model series F0030UU, which must be unique so that users can easily find support online. Sometimes using only the main device name can make it difficult for several users to find the right support. The weight of BLU F91 is 209 g grams and the body dimensions are 168.7 x 76.8 x 8.9 mm. These dimensions are ideal for modern devices. Lastly, the device is available in Blue color options. However, the availability of color options may vary by country and market. Some color options may only be available for a limited time or during specific events.

Build Quality

The BLU F91 features a body made of plastic, which is a common material used in entry to mid-level devices. While plastic is not a bad material in this modern era, it can feel cheap, be easily scratched, and lacks the solid feel of other materials. For flagship devices in higher price ranges, plastic bodies are generally not used, so if you find this material on the latest flagship device, it can be seen as a disadvantage for users.

Screen & User Navigation

The display screen configuration is a crucial factor for the user experience, and in the case of the BLU F91, the screen setup is ideal, featuring a resolution of 1080 x 2460 pixels combined with a screen size of 6.8". Additionally, the display screen also has several other configurations, including ~395 ppi density.

Another important factor to consider for the display screen is the display panel hardware. Good display panel hardware will greatly enhance the user's experience. The BLU F91 uses the very common display panel hardware, IPS LCD, which is suitable for entry-level to mid-level devices. However, it is not recommended for flagship devices with higher prices unless there is a special screen technology innovation implemented.

The physical buttons on the BLU F91 are positioned and designed for easy use, with clear functions such as powering up the device or adjusting the volume level.

CPU & GPU Performance

The processor and graphics hardware are vital components for any device, as they handle the majority of the software tasks and rendering graphics. In the case of the BLU F91, it utilizes the MediaTek Dimensity 810 for the CPU and Mali-G57 MC2 for the GPU. But, the question is: are they good enough?

The answer is yes. This CPU and GPU combination is capable of handling multiple tasks on the device, including running games, opening apps, and rendering 3D images at their maximal limit. Users can expect good performance from these hardware components.


In addition to CPU and GPU hardware, memory hardware is also a very important sector for ensuring the best user experience when using a device for multiple purposes. The memory sector includes the RAM capacity, internal memory storage, and support for external expansion memory. So, is BLU F91 good enough in terms of memory performance?

When we look at the memory combination specification, we can see that BLU F91 has 8GB of RAM and 128GB of internal memory storage capacity. The user can get more storage on this device because BLU F91 does support external memory expansion using MicroSDXC.

Therefore, does BLU F91 have good memory performance? Based on the specifications, it is good enough for any modern use, but it also depends on the user's perspective and needs.


Just like other modern smart devices available today, BLU F91 has a camera feature that enhances the user's experience. The main/rear camera feature of BLU F91 has a Quad Setup camera configuration feature.

The main/rear camera specification of BLU F91 is (Main) 48 MP, f/1.8, 1/2.0", 0.8µm, PDAF for the main camera configuration setup. There is also a secondary camera feature available with a specification of (Ultrawide) 5 MP, f/2.2, 115˚. The BLU F91 also has a third camera feature with a specification detail of (Macro) 2 MP, f/2.4. Lastly, there is a fourth camera configuration setup on BLU F91 with a specification of (Depth) 2 MP, f/2.4.

BLU F91 has a Single Setup front/selfie camera feature. The main selfie camera specification on BLU F91 is 16 MP, f/2.0.

Mobile Network

BLU F91 fully supports mobile network broadband. It is equipped with a Dual SIM, Nano SIM Card feature. The device supports mobile network technology using 2G / 3G / 4G / 5G. Users can easily switch between mobile network modes when needed.

Connectivity features

When it comes to modern devices, having multiple connectivity options is essential, and the BLU F91 has all the necessary features.

Wireless connectivity options on the BLU F91 include Wi-Fi technology with a complete specification of Wi-Fi 802.11 b/g/n/ac, Dual Band and Bluetooth version 5.1, A2DP, LE. In addition, the BLU F91 also fully supports NFC technology.

Wired connectivity options include the USB Type-C Port technology, which can be very useful for connecting the BLU F91 to other devices such as desktop computers.

OS & Security

As a device designed for modern users, BLU F91 should be operated by a smart operating system. The good news is that BLU F91 already uses a smart OS known as Android 11.

What about security technology on BLU F91? The BLU F91 has powerful security protection because it uses the default security system from the software OS combined with the Fingerprint (at the side) security hardware technology, which provides more security against unauthorized access.

Speaker & Sound

The speaker hardware on BLU F91 is similar to most other devices, with a good loudspeaker quality for calling and playing music. However, BLU F91 fully supports the 3.5mm jack technology, which is a great feature to have.


BLU F91 comes with a 5000 mAh battery capacity and Li-Po battery model. This battery specification can be used for all-day use in normal terms. But don't worry if the device is on low battery state because BLU F91 already supports Fast charging 18W, Wireless fast charging 10W technology. This means the charging time will be shorter, depending on the wattage of the fast charging feature. Normally, the battery can be fully charged in under 2 hours, 1 hour, or 40 minutes.

This device also comes with USB Type-C port technology. It's great because the USB Type-C is a universal charger port that can easily suit most charger cables on modern phones today.
