I’ve raised this issue previously, however it was never addressed.
My Mudi (EU 4G) displays full signal on the built in display, no matter what, with the exception of full signal loss. However this contradicts the signal displayed on the web interface, which shows the signal strength properly.
The forum seems to be freaking out about the photo and 1screenshot (both under 5MB, yet I keep getting the “this file is larger than 5000kB, why not upload it to a cloud host” message), so here’s a Google Photos album of it.
It would be great if this issue could be addressed, as it hinders the functionality of the on-device display, making the signal indicator useless.
