Overall Best: Samsung Galaxy S21 Plus 5G

The Samsung Galaxy S21 Plus 5G is your best bet if you want a phone with a flat screen that checks a lot of boxes.

This device comes protected with Gorilla Glass Victus, to make sure your accidental drops don’t leave you with a broken screen.

Plus, it is a water and dust-resistant phone, so you can occasionally shoot pictures or videos underwater.

Talking about taking pictures, you get a lot of options when it comes to the cameras on the device. Three on the back, while the front has a single selfie shooter.

You’re definitely going to be amazed by the telephoto cameras if you’re into cameras.

Finally, you get the Snapdragon 888 chipset on the device, to ensure you can carry out a lot of activities without slowing down.

It is the latest and fastest chipset today.

Best Alternative: OnePlus 8T

Although not as powerful or a water-resistant device like the S21+ 5G, the OnePlus 8T comes packed with features you are still going to be impressed with.

Gorilla Glass Victus has been replaced with Gorilla Glass 5. It’s not as tough but is still able to give the screen the protection it needs from scratches and accidental drops.

However, just like the S21 Ultra 5G, you do get that high refresh rate on the AMOLED screen they both have.

On the back of the OnePlus 8T are four cameras that can take amazing shots.

  • Fast device (good for gaming)
  • Good battery at 4500mAh with fast charging

Best Budget: Samsung Galaxy A51

Who says having a budget device means not having premium qualities? The A51 by Samsung is one of those devices that are cheap but still impressive.

Although you’re not getting a fancy build here, the device comes protected with Gorilla Glass 3, keeping it safe from scratches and short drops.

Yes, the screen on the A51 is an AMOLED screen, so expect those deep blacks and crisp displays.

The only thing not amazing about this device is that it has an Exynos chipset, making it not as powerful as a device running on a Snapdragon chipset.

It’s not all bad, as Exynos devices are still good enough to carry out most activities without necessarily slowing down.

See the current price on Amazon.

If you’re interested in 5G, you won’t be getting it on this A51 version, however, Samsung was nice enough to make a 5G version for this.

Everything about the devices is the same except the fact that one has 5G while the other does not.

  • Cheap
  • Nice display
  • SD card support
  • Dedicated SD card slot
  • Has a headphone jack
  • Slow-motion video support
  • Fast charging support


  • Not a Snapdragon-powered device

Get the Samsung Galaxy A51 on Amazon.

Best Budget Alternative: OnePlus Nord N100

While the A51 offers up to 8GB RAM, the Nord N100 by OnePlus just offers a 4GB RAM variant.

You do get Gorilla Glass 3 protection here, however, you are not going to be protecting an AMOLED screen but an IPS LCD screen from scratches.

LCD screens are fine but not as detailed as AMOLED screens, so if you’re coming from an AMOLED one, I would strongly suggest not getting this device.

You’ll go from “what’s wrong with my eyes?” to “what’s wrong with this screen?”

However, the good part about the screen on the Nord N100 is that it is has a 90Hz refresh rate, so you’re not going to experience it stuttering.

This is one of those devices that look good and good enough for your day to day activities. Its 5000mAh battery is good for that.

  • Big battery
  • Fast charging
  • SD card support
  • Dedicated SD card slot
  • Headphone jack


  • Average screen
  • Not very fast

Best Battery: Xiaomi Poco X3 NFC

A phone with a big battery doesn’t really need 5G, if you want one with 5G, go to the next phone on the list.

5G is still in its early days and a huge battery drainer, but it is slowly getting better and with time, all phones (or at least most phones) will come with 5G.

The Poco X3 NFC is one of those phones that’s fast and powerful with its 5160mAh battery.

You’re basically having a flat screen phone that is built to handle a lot of multitasking. That’s because it comes with 6GB RAM and a good Snapdragon chipset.

The downside of this device is that it has an LCD screen, meaning you’re not getting a very detailed display, however, it has a high refresh rate at 120Hz so you’re now left with a smooth display that isn’t very vibrant.

Besides its screen, there are other features you’ll be happy with. Like four cameras on the back, a single 20MP selfie shooter, and Infrared support.

With infrared, you can use the device as a remote. Control your TV or mess around with people.

  • Big battery with fast charging support
  • Headphone jack
  • Gorilla Glass 5
  • Inexpensive
  • SD card support


  • Not water resistant
  • Uses SIM slot for SD card

Get the Poco X3 NFC on Amazon.

Best Battery Alternative: Xiaomi Redmi Note 9 Pro

The main differences between the Redmi Note 9 Pro and the Poco X3 NFC are 160mAh and 5G. You’re still getting an LCD screen here, not with a high refresh rate but with a 1080p resolution.

The screen is protected with Gorilla Glass 5 so expect it to be safe from scratches and those short accidental drops.

One of the things you’re not going to be too happy with is the fact that you’re getting a low-end chipset here. This means you’re going to experience some lag from time to time.

On the other hand, you get a decent set of cameras. Three on the back and a single selfie shooter. They both record 1080p videos at 30fps.

Get this device if you want to experience 5G on a budget.

See the current price on Amazon.


  • Big battery
  • Cheap
  • 5G
  • SD card support
  • Dedicated SD card slot
  • Headphone jack
  • Infrared


  • Not ideal for gaming or multitasking

Get the Xiaomi Redmi Note 9 Pro on Amazon.


There are a lot of reasons why flat screen phones are better than curved screens. Phone manufacturers are slowly starting to get rid of curves or at least reduce them.

So, you may get a phone that looks curved, but you’re not going to experience those negative effects that come with a curved screen.

This article is going to get updated as more devices get released.
