OnePlus 8T

Despite being called a midrange smartphone, the OnePlus 8T remains the best flagship killer due to its cost-effective pricing. While powerful processors, gamer-friendly smartphone displays, and high-capacity batteries continue to defend the device’s fort, we were impressed with its excellent performance and user-friendly specifications.

Hands-on testing showed that Qualcomm’s Snapdragon 865 processor easily justified the price tag and felt even more than expected. Despite the 7nm chipset architecture, this SoC is best known for its octa-core processing setup, and a single Kryo 585 core can reach a maximum speed of 2.84GHz. Combined with the Adreno 650 GPU, this processing module can handle any number of multitasking tasks.

When it comes to smartphone memory, the OnePlus 8T has two variations: one with 8GB RAM and one with 12GB RAM. However, we are currently using the latter and experiencing a performance as smooth as butter, despite opening all applications.


  • RAM: 12GB
  • Processor: Snapdragon 865
  • 55″ AMOLED display at 120Hz
  • Front Camera: 16MP wide front camera
  • Rear Camera: 48MP Main +16MP Ultra-Wide +5MP Macro +2MP Mono
  • Battery: 4500mAh (65W fast charging)

Vivo X90 Series

While the Vivo X80 Pro was a great device, its successor has taken it to the next level. The vivo X90 series consists of vivo X90, vivo X90 Pro, and vivo X90 Pro Plus. It is very similar to the three models, and the size and screen sizes are the same. It also has the same fake leather and a large circular camera housing.

These terminals also feature dual SIM functions and have overwhelming specifications. The MediaTek Dimensity 9200 processor powers the X90 and X90 Pro, and the Snapdragon 8 Gen 2 chipset powers the X90 Pro Plus. Also, the large camera housing is not just for appearance. The X90 series offers the best camera system in the smartphone market, including ZEISS optics, high MP sensors, and various options.

These devices sound expensive but very well compete with equivalent options.


  • Display: 6.78″, 1260 x 2800

ASUS ROG Phone 7 and 7 Pro are the latest models released by this manufacturer, and these devices are exceptional. The Snapdragon 8 Gen 2 processor, 12-16GB of RAM, 512GB of storage, 6.78″ 165Hz display, and 6,000mAh battery all have the best specifications.

These devices are also equipped with a shoulder trigger. There is no wireless charge, but it can be supplemented with a quick charge of 65W. Also, if you choose the Pro version, it comes with a cooling fan system integrated with a 2-inch screen on the back.

The ASUS ROG Phone 7 review gave few complaints. The camera could be better; only the IP54 grade and the promise of the update should be better (two major OS updates and a four-year security patch). Other than that, the performance is remarkable, the display is gorgeous, and the battery life is outstanding when you are not playing a game.

  • SoC Snapdragon 8 Gen 2

Samsung Galaxy S10e

Galaxy S10 is a fairly new terminal in the market, following the recently announced Galaxy Note 10. The Galaxy S10e is a global flagship model that supports dual SIM standby—a 5.8-inch dynamic AMOLED display with 2280×1080 resolution. The main difference from the standard Galaxy 10 is only the processor.

Apple iPhone 12

We reviewed many dual-SIM smartphones, but they were less impressive and efficient than Apple’s new iPhone 12. Best known for its improved design, class-leading cameras, and enhanced screens, this device is worthy of praise from smartphone enthusiasts.

The iPhone 12 series consists of four variations, including Mini, Pro, Pro Max, and Vanilla iPhone, but the latter has the perfect balance between performance and affordability. As for the processor, you can experience the magnificence of Apple’s A14 Bionic chip.

The 5nm chipset with six Firestorm cores can reach up to 3.1GHz maximum clock with up to two cores. In addition, quad-core Apple GPUs are available to support six-core SoCs. Speaking of RAM, iPhone 12 offers 4GB and may look overwhelming compared to other flagship models.

However, it is necessary to understand that the 4GB RAM of the iPhone 12 is equivalent to the 12GB RAM of other similar price models. There are three storage models, and the reviewed models have 128GB of ultra-fast storage.


  • RAM: 4GB
