The problem I have is that ghost touches occur on the display when typing letters on the keyboard. Periodically two letters pop up. More than 10 people complained to me about this on the S59 Pro. After removing the protective film from the display, it became less common, but this problem has not disappeared at all. Resetting all settings, setting the duration of delays and intervals of pressing did - did not help. I even adjusted the sensitivity of the display and the response time of the sensor, but did not completely solve the problem.
