BLU S91 Pro Display

The BLU S91 Pro smartphone is equipped with a massive 6.5-inch display screen. It is enough to pack up all of the phone’s contents. Doing daily tasks will be comfortable. Text a long paragraph, watch TikTok, or scroll over your social media will perfectly fit the screen.

A 720 x 1600 pixel resolution can support better viewing. This resolution has an HD+ quality, meaning the contents output will be shown in detail, with sharps and brighter colors. It’s very intense, and the brightness is sight-friendly for us.

The BLU S91 Pro contents’ graphics are well-detailed. It has a 270 PPI, and it is well-detailed. However, we still found some pixelated content here and there. Especially when you zoom in on the pictures to look at.


BLU S91 Pro Camera

The BLU S91 Pro is rocking its camera with its triple rear camera on the back. It consists of a 50MP main camera with 5P Lens and Samsung Sensor, 2MP with a wide-angle camera, and a 0.8MP as a depth camera.

The camera megapixels are stunning, and the features are incredible. The BLU S91 Pro has an AI mode that can detect the scene around you and adjust the camera to produce the best outputs.

It also has a time exposure, over-suppression exposure, and Multi Frame Noise Reduction (MFNR). We forget about the dual LED flash to get a brighter picture in dark-light situations.

Conversely, the BLU S91 Pro has a single camera at the front. It has a 13MP resolution and is great enough for taking a stunning selfie of you. This camera will produce a soft and naturally blurred background, so you will be at the center of attention.


A great camera’s megapixels will produce bigger files to be saved. Thankfully, the BLU S91 Pro knows these conditions and gives its users 128GB of internal storage. The capacity is enough for you to save the pictures and videos and get the apps into your device.

The 128GB is not the actual size of your internal storage. It will decrease because of preloaded apps and system configurations already installed.

Don’t worry. Users can overcome this burden by following these two alternatives. First, you can start by clearing the cache and curating all your unwanted files regularly. Or, you can use a MicroSD card to become additional storage. You can add up to 256GB of the external card, and you have to spend extra cash to get it.

BLU S91 Pro Side View

The BLU S91 Pro smartphone employs an Octa-core MediaTek Helio G37 MT6765V/CB as its core system. Finding this on the BLU S91 Pro makes sense since it brings up the device to become a reliable and dependable gadget.

Running on the 4×2.3 GHz Cortex-A53 & 4×1.8 GHz Cortex-A53 speed rate makes the device run seamlessly without any burdens, especially when multitasking. So far, we didn’t face any struggles while going any apps back and forth.

Those chipset specs are coupled with the ideal 4GB RAM. This RAM can handle every performance very nicely for a mid-range phone like the BLU S91 Pro, especially when we’re on heavy duty.

No laggy happens. Playing intense games like Mobile Legends and PUBG is comfortable enough. Accessing some apps that need extra loadings, like e-commerce and social media, is also smooth. However, we recommend not using the device with high force because it will be heating.

Android 12 OS (Operating System) on the BLU S91 Pro deserves a shout-out. Even though it’s not the latest one for the moment, this OS is a nice standard. The features available here are amusing and can improve our work towards this phone.

There are a lot of modification refreshes on Android 12. One of them is the more personal users’ experience. This device can transform dynamically for its overall screen’s appearance. Just choose your favorite wallpaper, and you will find out why. Their privacy update also becomes more secure and fully controllable.

Security sensors are a must, too – at least have preventive measures against irresponsible people. The BLU S91 Pro has both of the two security locks; fingerprint reader and face recognition. The fingerprint reader can be found on the back of the phone. These two are useful for you to unlock the device easily and, of course, securely.

Besides those, this smartphone also has some default sensors. Those are accelerometer sensors, proximity sensors, and compasses.


Users can connect with other people – not just their family but also worldwide with the help of a 4G LTE network. At this rate, 4G LTE has become the most reliable network connectivity for most parts of the world. Obviously, the internet is still at a fast pace. Wi-Fi is also available as an alternative for you who want to save your mobile network.

Bluetooth becomes the primary connectivity to let your BLU S91 Pro smartphone connect with other devices. Do you want to share files? Or, connect your phone with other Bluetooth devices, just like a Bluetooth speaker and headset? Bluetooth is the answer. The other connectivity is the USB Type-C. It can connect to a computer.


The BLU S91 Pro smartphone knows how to satisfy its users. It has a huge 5,000mAh battery capacity to let you run the device all day long. As a mid-range smartphone, this spec absolutely gets one star for us.

This device promises to last up to 3 days, even though we know it isn’t very accurate because it depends on every user’s behavior. A non-removable battery type is common for most smartphones nowadays and is known for its durability. It has minimal risks of getting damaged.


The BLU S91 Pro smartphone is a choice for those of you looking for a reliable smartphone with current standards. There are some features and specs that we love the most. For example, the sleek and minimalist design, the camera, and the internal storage.

This phone is affordable for all of the features of this mid-range smartphone. It cost only $220 in Q Link Wireless. You can get it for only $160 if you buy from Bestbuy. As the verdict of the BLU S91 Pro review, we give this device a yes!
