in my q10 pro the sound of the keys was activated by default and I write with an air mouse then with the keyboard that has by default the q10 pro if I do not deactivate the sound of the keys when I press them in the android keyboard menu I am usually block the device by pressing any of them randomly does not have to be the first but the third or fourth or the tenth letter to press, this does not happen if I deactivate the sound of the keys to press them as I said before but I do not know if it is cause of the keyboard or the air mouse but I have tried several air mouse and always happens, I think this does not happen with the original remote, anyway I say it deactivating the sound of the keys does not happen with any air mouse and installing another keyboard like gboard for example this does not happen even with the sound of the keys activated, really curious.
Could it be a peripheral management failure? since the air mice have a sensor connected to the usb I suspect something like that
