Is the front camera completely invisible behind the screen?

Mostly yes, but at certain angles and with a bright background, a faint grid can be seen above the camera. This is the world's first technology of its kind.

How is the selfie camera image quality?

As light has to pass through the screen pixels, the images are softer and less detailed than on regular phones. It's suitable for video calls, but not for professional selfies.

Does the ZTE Axon 20 support 5G in Estonia?

Yes, the device supports the n78 frequency, which is used by all Estonian operators for 5G offerings.

Is the screen bright enough for outdoor use in sunlight?

The OLED screen offers good contrast, but its maximum brightness (600 nits) is lower than that of today's top phones, which can make reading difficult in direct sunlight.

Does this phone have a memory card slot?

Yes, the Axon 20 has a hybrid slot, meaning you can use either two SIM cards or one SIM card and one microSD memory card.

Does the phone have a headphone jack?

No, there is no 3.5mm jack. To use headphones, you will need to use a USB-C adapter or Bluetooth headphones.
