I’m a brand new Trident operator and also new to Android devices. The touchscreen on my JXD S192K controller became unresponsive today while downloading videos from a dive onto an SD card. I rebooted the controller a couple of times (including the power + volume up technique found via googling the problem) but still no touch capability. Joysticks and buttons work fine, and I can even launch the Trident app, but without touchscreen I don’t think I can access all pilot functions. The controller has not been exposed to water, extreme conditions, or anything unusual. The entire system (ROV, controller, topside, tether) is 2 months old, and today was its second dive.
(1) Have I overlooked a simple solution to an unresponsive touchscreen on an Android device (e.g., some setting that deactivates/reactives touchscreen)?
(2) Should I try a factory reset, and if I do, will I need to re-install the Sofar Trident app? (Note - the controller came with the app pre-installed shows a Sofar splash screen on startup.)
(3) Other suggestions?
