I have 2 different imx7d sabre boards here that i have loaded the 8.0 Oreo release on and have not had any issues with the dashboard/launcher but I have now loaded the Pie release binaries from the NXP website and I have great difficulty pressing any of the buttons on the dashboard. I can swipe between screens left and right and pull down the top menu but cannot select anything on the screen such as the apps button to launch anything.
This happens with the release binaries from NXP and my own build of the Android 9.0.0_2.2.0 release. We managed to bring up the keyboard and it seems as though the device recognises input all over the screen it's just not recognised by Android as a press on anything.
I revert to the o8.0.0_1.0.0 from NXP and everything becomes responsive again on the device and the launcher/dash. If I load the 9.0 release on my 7ulp devkit that device works normally.
Have you experienced this problem or is there a way to resolve this?
