I had originally set the brightness of my Glo to 1%, One day, after sideloading a book, I noticed a slight flickering. It was subtle, but noticeable. It went away when I changed the brightness to 2% (still happened at 1%) and I chalked it up as a weird but overall irrelevant issue. Today, again after sideloading a book, the same very slight flickering happened, now at 2%. I went back to 1%, same. 2%, still there. At 3%, it's fine.
Has anyone observed a similar problem? Or are there any theories on why that happens and whether it can be fixed? I'm fine with the 3% brightness, but I'm beginning to wonder if this will turn into a recurring issue where I have to frequently increase the level of brightness.
I haven't changed anything else, no firmware upgrades, no custom content except one font (that was after the 1% flickering started, but already some time ago). I did a reset, which had no impact.
Any ideas?
