WARNING: I installed the 2020-01-16 release and lost the touch screen. Ran full diagnostics and all passed. Reverted back to the 2018-10-16 release and regained all functionality.

EDITED TO ADD: This appears to be a problem only for installations on Macs. Prime Users installing with Win10 report no problems.

Reverting to Firmware 20181016 or 20191120 Beta on MacOS installations returns Touch Screen functionality.

Installing from Win7 and Win10 also sometimes results in loss of touch screen; some users report no problems, others lose touchscreen. As noted above, reverting to prior version restores touchscreen.

HP has corrected the loss of touch experienced with the 20200116 Firmware. The 20200121 Firmware appears to work without loss of capability.

Installed with a Mac 10.15.2

Last FW, 20200122, installed whiout errors, and the screen works at last fine throug the new capbility to change the refresh rate and now the screen with full brightness works without vibrations.

"Added ability to adjust screen refresh rate using [ON] + [SHIFT] + [+] or [-] key combo"

Many thanks for these posts

I have encountered an error, which perhaps detects a bug in HP PRIME G2 (hardware). For example, if I do this calculation with the virtual calculator: "exp (-10^49-10^49*i)", I rightly get zero. If, however, I perform the same operation with my HP PRIME G2 (i.e. hardware version with firmware 20200121), an error is displayed: +Inf. This error, found on the G2, is not of little importance. For example, if I want to calculate the first-kind Bessel-function, BesseJ(n, z) with Arg(z) int(exp(-(2+3*i)*sinh(t)-2.5*t),t,o,+inf) --> 0.152804387425-9.90045195322E-2*i (on virtual PRIME)
int(exp(-(2+3*i)*sinh(t)-2.5*t),t,o,+inf) --> undef-undef*i (on "hardware" G2 PRIME)
