1. Samsung Galaxy S20 5G

Samsung has long been known as one of the world’s best Smartphone manufacturers. Taking the top spot in terms of sales, their popular “S” line-up has been making headlines since it was first released more than 10 years ago. The Samsung Galaxy S20 5G is no exception to the quality and groundbreaking features that this brand has built its name on.

Packing a 6.2” Quad HD+ Dynamic AMOLED 2X Infinity-O Display at 3200×1440 and with a 120hz refresh rate, this phone has one of the world’s leading displays. This monster display is powered by an Adreno 650 mobile GPU, alongside a beefy Octa-core processor that was designed by Samsung themselves. This phone has 128GB of internal storage, 8GB of RAM, and you can even add a microSDXC card if you don’t need the space for a second sim card.

As for features, like most of the “S” line, this phone comes with rapid wireless charging built-in. The front-facing camera has a beefy 10MP sensor, with the lens being hidden in a cut-out in the main screen. The main camera is a triple-sensor array, including a 12MP wide and ultra-wide-angle lens, and a 48MP telephoto lens. Unlike other phones on the market, this device is available in a wide range of colors that look excellent.

One of the weaker points of Samsung devices has always been their operating system. Running Android 10 with Samsung’s own OneUI over the top, this has improved greatly over the years, and most people wouldn’t consider this a weak point for the phone. Having expandable storage is also great, but many users will struggle to wave goodbye to the dual-SIM functionality to be able to use it.

2. Apple iPhone 11 Pro Max

Apple was the first company in the world to reach a market value of $1 trillion, and this is largely thanks to the success of its iPhone lineup. Once viewed as the expensive option to many, iPhones are more competitively priced than ever before, often making them the same price as other flagship devices.

The iPhone 11 Pro Max is Apple’s most recent flagship device. With a 6.5 inch Super Retina XDR OLED display alongside a Hexa-core processor and GPU that Apple designed for themselves. You can choose to have the phone in 64GB, 256GB, or 512GB, but each version comes with 4GB of RAM. These phones use NVMe storage, making it some of the fastest on the market.

The 11 Pro Max comes with a triple rear camera array, including 3 12MP sensors with a wide, ultra-wide, and telephoto lens, and a front-facing selfie camera that is also 12MP. The true power behind these cameras comes in the form of Apple’s image processing software. Well-known as some of the best in the world, you simply can’t find it on other phones.

The biggest downside that comes with Apple devices will be a benefit to those that already own a Mac. There is a tight eco-system surrounding these products, with apple working extremely hard to push people towards using their devices for everything. iTunes has always run incredibly poorly on Windows machines, for example, and this can be a major deal-breaker for a lot of smartphone users.

3. ASUS ROG Phone 2 (ZS660KL) Smartphone

Asus is probably best known for their PC components than their smartphones. This brand has been breaking into the phone market for years, though, with their ROG (Republic of Gamers) phones being marketing towards those who love mobile gaming. This PC-building heritage can be seen in their modern smartphones.

The ROG Phone 2 comes with a Qualcomm SM8150 Snapdragon 855+ and an Adreno 640 to power the games you want to play. This phone is available in 128GB 8GB RAM, 256GB 12GB RAM, 512GB 12GB RAM, and 1TB 12GB RAM storage configurations, giving users loads of choice and making it easy to change the storage size in the phone you want to use. With a pair of DTS:X stereo speakers, few phones are able to provide the audio experience that comes with this device.

This Asus phone has a dual-rear camera, with 12MP ultra-wide and 48MP wide lens, along with a 24MP selfie camera. Many of the main features on this phone are game-oriented. Like the controllers you’d get with a games console, this phone has shoulder buttons that can be used as extra inputs for games. Its USB charging port is located on its side to enable better landscape use, while the port itself has been redesigned to allow attachments to be added to the phone.

These attachments include game controllers, additional cooling fans, and even an extra screen that can be used with certain games. Of course, all of these features sound nice, but you have to spend a small fortune in addition to the phone if you want them. For many people, the availability of cheap aftermarket attachments for other phones will make this feature unimportant.

While this entry is impressive, Asus has a long way to go before they are able to dominate the phone market. Like many of their products, it’s easy to tell that this device has been designed for gamers based on its appearance, and this isn’t very good for professionals that would like to try it out. Alongside this, some versions come without any warranty whatsoever.

4. OnePlus 8 Pro Ultramarine

Child company of cell phone giant Oppo, OnePlus first debuted in the West back in 2014. Starting as a “flagship killer” device, this company has since fallen into step with brands like Samsung and Apple, providing phones with top-specs that are accompanied by top prices. This phone uses OnePlus’ Oxygen Android skin.

This phone matches its competitors in power, with an Octa-core CPU powered by a Qualcomm SM8250 Snapdragon 865 chipset. Alongside this, the phone has an Adreno 650 GPU. You can choose to have this phone with
