I've just gone through 12 hrs of thinking that my phone's bricked.
It wouldn't recognise the USB charging cable (yes I tried many chargers & cables).
I thought it was the Graphene update as I also had a weird debris detected message show & quickly disappear while updating.
I had 500K sats sitting on my Aqua wallet, not backed up 🤦♂️
I was about to switch the phone on & quickly backup the Aqua wallet with the remaining 2% battery when I connected it into the Linux PC. The screen showed 2% & then 3%, when it got to 5% I knew it was charging.
I don't know if plugging it into a PC woke the port up but it's charging as normal now.
I also don't know who needed to hear this, but sometimes you get no warning when devices die.
Have you backed up those 12 words anon?
