How to disable the touch screen on the edges of the smartphone?

Question

Mobile devices

Hello.
The display on my smartphone was broken and replaced with a new one ordered from China. The sensor of the new display was not very good. Now, when holding the smartphone with your hand, the display is falsely triggered at the edges. Since part of the skin of the hand touches the edges of the display.
How to get rid of this false positive?
PS I assumed that this problem can be solved by software disabling the sensitivity of the edges of the touch screen. But maybe there are other ways.
PPS Characteristics of my smartphone:
1) Xiaomi Mi4c
2) CyanogenMod 13.1 (Android 6.0)
3)
Rooted 4) Xposed installed
