The first moment you see the Blu F91 5G smartphone, you instantly notice its lux and premium appearance. Somehow, it radiates a different vibe from entry-level smartphones. Moreover, it has proportional dimensions, 168.7 x 76.8 x 8.9mm, which makes the device look tall and slim. A 209g of weight also feels right in our hands (it doesn’t feel bulky!)

The front area comes with a large display screen. It looks neat and pleasing to the eye, thanks to its thin bezels on all sides. Three main buttons are placed on the screen; even better, the front camera is placed aesthetically in a punch-hole design.

The back area is where you can see a beautiful Oceanic Blue gradient color. It comes with a subtle texture which gives us a deluxe vibe by looking at it. At the top, there is the triple main camera hanging on the left.

BLU F91 5G Display

As mentioned earlier, the Blu F91 5G has a large display screen. It’s a 6.8-inch screen, a common size in today’s mid-range smartphones. With this size, users can do anything comfortably. Playing games? Texting? Watching videos? This phone will give you a total experience.

Besides the screen size, this phone also has a 2460 x 1080 resolution. It means users will experience full HD quality. We’re impressed with the screen quality since it has sharper and more detailed outputs.

The Blu F91 5G is the latest version with a display quality above its predecessors. The screen brightness feels right; it isn’t too bright or too dark. It’s perfect for outdoor activity. The phone’s icons and pictures also don’t come out pixelated.


BLU F91 5G Camera

The Blu F91 5G has four cameras on the back and one at the front. The quad camera consists of a 48MP main camera. It comes with a Samsung GM1 sensor which is good for taking high-quality pictures. The next camera is a 5MP ultra-wide camera to capture a panoramic picture. The other is a 2MP macro camera for taking zoom-in pictures, and the second one is a 2MP depth camera.

These four have a balanced synergy to produce high-quality and social media-worthy pictures. Not only taking a picture, but the camera can also be perfect for recording 4K video and 1080p video. The rear camera already supports a Super Zoom feature, allowing you to zoom in 30x. Nice quality, indeed.

Move to the front. There is a 16MP camera that will make your selfie turns really good. It gives you a nice detailed picture with a smooth, naturally blurred background. With this camera, you can also take a video call.


The Blu F91 5G has a spacious 128GB of internal storage. It is the bare minimum in mid-range smartphones, but we’re okay with this. Even though the 128GB seems promising, the real capacity is lower than this.

However, just like other smartphones, the Blu F91 5G already provides expandable slot storage for you who need to expand the space. You can insert up to 256GB of MicroSD card into the slot, and the capacity will increase again, and you can add more files and download more apps with it.

The MicroSD card doesn’t come with the phone. So, it would be best if you bought it yourself. You can back up your files in the cloud if you want more practical solutions.

BLU F91 5G Side View

Performance-wise, the Blu F91 5G has a 2.4GHz Octa-core MediaTek Dimensity 810 as its processor. It’s a powerful CPU that supports the 5G technology and is specifically developed for mid-range smartphones.

Its 2.4GHz frequency boosts up 20% faster than the older processor, which can power up a great experience. The app’s response is smooth, even better when playing a high FPS game.

The CPU is combined with 8GB of RAM. Yes, it’s a huge amount of RAM for us. In case you don’t know, RAM is where every phone’s temporary data is stored. If you have 8GB RAM, you can easily access everything on your smartphone.

The 8GB RAM can even do the hardest daily tasks for you. Multitasking feels very smooth, with no obstacles at all. Opening the apps simultaneously won’t drain the performance even a bit. This CPU is perfect for you with heavy-duty activity.

Let’s talk about the Blu F91 5G smartphone’s brain. They use Android 11 as their operating system (OS). Even as the latest smartphone, they don’t use the latest android version as their system. It is one drawback point we’ve found so far, even though you can still get the latest version by updating it.

However, Android 11 still has a lot of interesting features. The tighter security features are still remarkable since we can control what kind of notifications we want to show. The conversations can also be manageable.

The Blu F91 5G has many sensors on the phone. These are the accelerometer, gyro, and proximity sensors. These all have different purposes; for instance, the accelerometer can be used for determining the users’ steps. The gyro sensors work perfectly for games to instantly change the screen’s orientations, and the proximity sensors to avoid accidental touches.

Other than that, the Blu F91 5G also has two security sensors available. Includes the fingerprint reader and face recognition. These two can be used for unlocking the device very easily (without passcode requirements).


The name indicated the Blu F91 5G phone’s main connectivity. Yes, this phone is already equipped with 5G technology for its users to have stable and faster internet connectivity. As a mid-range smartphone, actually, we’re expecting this feature. However, you can still use the older bands, such as 4G and 3G connectivity, with this phone.

If you prefer to not use your mobile data, you can always rely on Wi-Fi connectivity. This phone supports this feature and a mobile hotspot to turn your phone into a modem. 

The other connectivity available is Bluetooth and NFC. Bluetooth can help you to transfer files wirelessly to other devices. Meanwhile, NFC (Near-Field Communication) can help you pay by only using your Blu F91 5G.


The Blu F91 5G has a 5,000mAh of battery capacity. It is considered huge – even for a mid-range smartphone. We really appreciate this generous capacity. This phone claims it can last up to 3 days. Even though, in our opinion, it won’t last that long since every user has different activities and behaviors.

The most surprising features are they have quick charging and wireless charging features available on the phone. This can be helpful if you have a busy life and need everything to be faster and easier.


This phone is sold for $250. It is expensive, but it is targeted at mid-range customers, so we found no problem. It has many remarkable features and functions that are worth every penny.

We want to give a shout-out for its stunning-looking appearance. The phone’s 5G connectivity and large battery also seem promising. But we also want to mention their weaknesses; the Android 11 and the internal storage that is quite average for the device.

Blu F91 5G Pros:

  • Stunning appearance
  • Big battery
  • 5G connectivity

Blu F91 5G Cons:

  • Quite expensive
  • Android 11


As usual, we have two alternatives for you who find this phone is different from your taste or needs. First, there is a Blu Bold N2. It’s the same brand as the Blu F91 5G and has the same price. But we noticed that the Blu Bold N2 doesn’t come with wireless charging.

The second one is the Nokia G400 5G. The price is below the Blu F91 5G, but it also lacks wireless charging. And the processors’ quality is different from the Blu F91 5G one.
