In terms of resolution, we 1080 x 2400 pixels with a display that has a 20:9 aspect ratio. The front panel is also protected Gorilla Glass 5 exactly like the backside as this is a glass sandwich phone. Coming to the performance, we get the latest Qualcomm Snapdragon 750 5G, which is an octa-core processor with 2×2.2 GHz Kryo 570 cores and 6×1.8 GHz Kryo 570 cores. It comes with Adreno 619 for all the graphics intensive tasks.

Coming to the cameras, we get to the USP of this device, which is the primary camera on the rear side. It is a quad-camera setup at the back with a 108MP primary sensor paired with an f/1.8 lens, an 8MP ultrawide sensor paired with an f/2.2 lens, a 2MP macro sensor paired with an f/2.4 lens, and finally, we have a 2MP depth sensor paired with an f/2.4 lens. Coming to the front, we get a 16MP selfie camera housed in the hole punch at the screen’s top.
