Hello Nizar,
Before you buy another NanoVNA, what brand of NanoVNA-F do you have Sysjoint or Deepelec?
Have you upgraded to the latest firmware?
If it is a Sysjoint, they no longer support the NanoVNA-F, but the Deepelec FW has been found to work on the Sysjoint unit OK.
You just need to be careful to flash the correct file from the download. The latest Deepelec FW is V1.0.5.
You should do a complete recalibration including the touchscreen calibration.
I have a Deepelec NanoVNA-F HW V3.1 (3 button) and the touch screen is very reliable.
