The display shows in full HD with a resolution of 2340 x 1080 and it’s 6.3-inches long. The screen ratio is 92.7% of the total dimensions of the device and the screen reads out with clear, vibrant colors.

OS and Processing Power

The Android 9 Pie operates the Umidigi S3 Pro system and it’s Android’s smartest and fastest mobile OS to date. The Umidigi makes a point not to use any third-party user interfaces and maintains the default Android look.

The processor is the AI Master Helio P70 which is built to multitask apps and deliver a fast 2020 mobile gaming experience to Umidigi users.

A multi-core and multi-threaded APU gives you top efficiency, as does its advanced AI-driven processing system. An Octa-core CPU ensures that you’ll never be waiting for your pages to load or crashing apps when you try to run too many.

For a smartphone, the Umidigi S3 Pro has a huge amount of RAM at 6GB, which is just under what many commercial laptops have. It has 128GB of storage space as well so all your games and high-resolution photos can be stored without worrying about running out of room for movies and music as well.

If your goal is to play a long session of Fortnight or PUGB without any lagging, the Umidigi S3 Pro has your covered.

Dual Cameras

One of the main selling points of the Umidigi S3 Pro is the two cameras. The main camera is a 48MP Sony IMX586 lens with superior clarity and advanced algorithms that allow the lens to detect even the most subtle details in your surroundings. The Helio P70 AI sorts out the information to give you mind-blowing clarity on the rear-facing camera.

The other camera is a 12MP telephoto lens for distance shots. You can zoom in pretty far while keeping the picture clarity stable. A Dual LED flash helps you keep track of details in lower lighting situations.

The low-light camera function is one of the things that the Umidigi S3 Pro is quickly becoming known for. This is because the IMX sensor supports 4-in-1 light fusion with a large pixel size for consumer-grade phone cameras.

Night-time photography for camping trips, bird watchers, or romantic nights on the town is easy with the Umidigi S3 Pro. Its AI reduces photo noise to give you a vivid image even when you no longer have the sun to back you up.

In addition, the selfie camera is a 20MP Sony IMX376 lens with the same AI that gives you reduced noise and a vibrant photo every time. The Umidigi S3 Pro is known for its cameras so if you’re a blogger or on a family vacation or an unforgettable night on the town, this smartphone is like having a high-powered, high-resolution Sony camera in your pocket at all times.

Battery Life

The battery on the Umidigi S3 Pro is equally impressive. It has 18W of charging power, which gives you a hefty backup when you’re not plugged into the wall or the Type-C USB port. The 5150mAh battery is sturdy – most consumers would be perfectly satisfied with how long it lasts.

Network Connectivity

The Umidigi S3 Pro supports major LTE networks on a fast-working data transfer system that makes it ideal for people who travel for business. The S3 Pro has over its previous models its dual SIM slots with 4G VoLTE in both of them, functioning at the same time.

Whether you’re on a 2G or a 4G FDD-LTE network, the Umidigi S3 Pro will give you what you need to keep working.

This includes fast data upload and transmission, a reliable LTE connection, and less power consumption than your average consumer smartphone. Due to a multi-function NFC, the Umidigi S3 Pro also supports non-location specific Google Pay services and other virtual currency transactions. This is particularly useful for people who frequently travel for business and will ensure that whether you’re paying through Google or on-vehicle payments, you never need cash with the NFC’s cardless transaction system, secured by encryption and a dedicated processor.


If you’re thinking about buying the Umidigi S3 Pro, then the price will naturally be a major selling point or detractor. The phone launched at around $300 but discounts are available if you shop around.
