The phone has a large 6.74 inch AMOLED display with a high resolution of 1240 by 2772 pixels and an extra fast 144hz refresh rate.
The display is very bright, measuring up to 480 nits, and supports 10-bit color depth and HDR 10 plus for great color accuracy.
The phone has a pair of stereo speakers that earned a good score on our loudness chart and provide decent sound quality with clear vocals and highs.
The realme GT3 has an IR blaster which allows you to use the phone as a remote to control appliances, and an under-display fingerprint reader for convenient biometric authentication.

Weaknesses

The ultra-wide camera produces low-detail and noisy photos, and the selfie camera takes blurry images with lack of fine detail.
