Random screen switching on Devo 8S

Hi,

I've tried Deviation on my Devo 8S (0.8 A under battery) and run to this wierd issue. It seemed to work fine for few hours, now it's like this.



Just random screen exiting, just like somebody was tuching screen to exit. On clip I've tried to show calibration, but 1st pont just gone (another random point?). Tried this on v.3.0.0 official, and nighly build, but still no good. Reflashing doesn't fix it. Any ideas?

For me it looks like a uncalibrated screen, but from time to time it seems to work ok (like walking through the inputs to PPM8).
Does any of the buttons like EXT / ENT has a problem?

Do you want to test the 3.1-beta? There are some improvements for the touch screen which should work for Devo8 (takes the average of multiple measures).

Screen was calibrated at start, but it radomly selects something, even when I don't touch it it may go to select model screen for example. Notice selecting THR works fine, and after going to last item on list Cancel button lights up unselected.
Buttons looked ok, but I used them maybe twice, so I'm not sure what to expect.

Just flashed oryginal Walkera firmware - works fine, so no hardware problem.

I may try beta, if different from Nighly build, models form 3.0 are recognized in it?

3.1-beta is differnet from nightlies. The model files are recognized, but the gui has changes so save them before using the 3.1 and restore later.
