Screen display refresh rate test hertz
With this App it is possible to visualize, if the own Smartphone can handle a certain Display Refresh Rate or not. It shows the current Frame Rate as well. You can choose to test the refresh rate against 60, 90 and 120 Hertz / Hz. If the smartphone is capable of the selected refresh rate, then all LEDs will continuously and smoothly light up one after the one. If the smartphone has a problem with a certain refresh rate, some LEDs might remain yellow or even red. A yellow LED means the frame was delayed. A red LED means the frame was missing at all. Yellow LEDs indicate that the smartphone is able to handle the selected refresh rate, but the CPU and GPU might be under load. Red LEDs indicate that the smartphone is not able to support the selected refresh rate.
