"The Redmi K30 Pro comes with a standard 60Hz refresh rate, but developers have been able to increase it to 80Hz via an unofficial software tweak"
Redmi K30 Pro smartphone was unveiled earlier this week in China and rumours are rife that it might launch as POCO F2 in India. Despite packing in flagship hardware like the Snapdragon 865 SoC, 5G connectivity, and quad cameras, the phone lacks a higher screen refresh rate, which is a let-down for some people considering it is slowly becoming a must-have feature in 2020. Even the vanilla Redmi K30, which launched as the POCO X2 in India, has a 120Hz LCD display. Responding to the same, Xiaomi recently explained that it wanted to offer a full-screen design and an impressive battery life, which otherwise isn't possible on a 90Hz or 120Hz refresh rate. However, it seems some developers have found a way to increase the refresh rate, but you may not want to do that.
GizmoChina reports that some developers from China have managed to bump up the refresh rate of the Redmi K30 Pro from 60Hz to 80Hz through a software tweak. However, it should be known that this is an unofficial workaround and requires users to root their phone. For the unaware, similar to the processor's core frequency, the smartphone's display can be overclocked. But this is said to reduce the life span of the panel greatly and eventually stops functioning as well. A Redmi official warned on Weibo that this method is not recommended and advised users against rooting as it is risky and also voids the phone's warranty. To recall, developers had boosted the screen refresh rate of Mi 9 from 60Hz to 80Hz back in 2019.
The Redmi K30 Pro has a 6.67-inch full HD+ Super AMOLED display with HDR10+, 1200 nits peak brightness, and 180Hz touch sampling rate. The phone is powered by a 2.84GHz octa-core Snapdragon 865 SoC coupled with up to 8GB LPDDR5 RAM and up to 256GB UFS 3.1 storage onboard. It runs Android 10 with MIUI 11 custom skin on top. In terms of optics, the Redmi K30 Pro has a quad camera with a 64MP Sony IMX686 primary sensor, a 5MP macro lens, a 13MP wide-angle lens with 123-degree field-of-view, and a 2MP depth sensor. For selfies and video chats, there is a 20MP shooter. A 4,700mAh battery with 33W fast-charging support fuels the phone. There is an in-display fingerprint sensor for security.
