Mobian screen dims

[JustineSmithies]

Do you have enough power, such as battery charged enough or the charger connected ?
    Some others have had problems attempting to power their phone from their laptop USB port.

Perhaps there is a problem with your SD card, or possibly the image on your card...
      Though if you are able to 'log-in'  it would more likely be a power problem.

(Personally I use Balena Etcher to flash my SD cards (all new cards) and I have not had a bad image yet)

I have the Brave Heart Edition phone as well,  running Mobian also.

Phone is fully charged. I've used dd and belana and various cards plus todays nightly. Everytime I get the swipe up to login and enter 1234 and i briefly see the ap drawer and recently it looks like a quick flash of a language page and the screen is still lit but very grey near black. I can push the power button to lock and then unlock but the lock screen loks slightly dimmer each time allowing me to enter 1234 but to the blank page.
I can easily flash Manjaro, PmOs using Pmbuild and UB no issues. Just cannot seem to get Mobian to work. I'm game for any way of turning off screen dimming if its possible to access via usb as i have no sim card in and obvs the wifi hasnt been setup yet.
