Herelink problem

Hello everyone.
today I received a here link. it was working well and connected with cube orange. After some time of charging. I noticed a strange problem in the ground module. the display brightness is too low, can’t able to see what is in the display. Initially, I thought the module is switched off, later noticed the display is on, but the display brightness is too low. have anyone noticed this issue. How I can troubleshoot this problem.

thanks in Advance

Maybe some problem with the adaptive brightness? I belive you can turn it off in the settings.
