How about the contact list? Does the problem exist there?

Should we add an option to enable more debug info without needing a special firmware version?
We could use the black button for the info if debug is enabled.

I think I will add a permanent debug info screen to get more data.

Is the down key complete without function or is it only in specific screens?

Which commit id? (Menu -> Firmware Info -> [ commit id ])

Now that we have the keypad handling changed, we can use something like long pressing Blue+STAR to unlock keypad and long press Blue+HASH to unlock PTT.

- Press and release PTT -> Screen PTT locked
- Blue+* -> unlocked

Unlocking PTT with Blue+* only works, if the screen 'PTT locked' is displayed. So to unlock you have to press PTT followed by Blue+*. This can not be changed, as PTT lock is only to lock the PTT. All other functions work as normal. So Blue+* switches between FM and DMR. The only possible 'fix' would...

I will take a look and fix.

Pull request is on it's way. There was a bug in the keypad debounce part, that could lead to the lockup. The keypad function reads the I/O-pins and after 20ms reads the pins again. If these values are the same, it's a valid keypress, otherwise it's not. In the first case the key is processed, in the...
