OnePlus recently confirmed the launch of the OnePlus 8T which will be happening on October 14. Now, it is certain that the new device will be sporting a 120Hz display.
OnePlus 8T: Better screen than the OnePlus 8
Not only is the OnePlus 8T getting a 120Hz refresh rate, OnePlus CEO Pete Lau also confirmed that the phone will come with a 6.55-inch screen. This makes the OnePlus 8T the first non-pro OnePlus phone to get 120Hz - even the OnePlus 8 only had a 90Hz display.

OnePlus 8T price leaked on Amazon
An Amazon Germany listing also revealed the price of the new OnePlus device. The 8GB + 128GB variant is expected to be priced at €599 (RM2,897.61) while the 12GB + 256GB variant will be priced at €699 (RM3,381.35), meaning it'll be cheaper than the OnePlus 8 when it was first launched despite having a better display.
