My Trezor7 charging went low to 7% and the icon became yellow. I put it to my Oneplus 8 charger what charged it fully 100% (and it became quite hot) but the yellow icon stayed, stayed even next day, it showed the charging state with a yellow blitz icon. I was a bit desperate that maybe I fucked it up with the phone charger. Next day I connected it to my PC what quickly charged it fully from the 97% and then the yellow icon disapperad and switched to the usual black and white icon and the charging percentage.
What was this yellow thing?
