After recent firmware update around 1 month ago, display setting of my Edge 530 does not work at all.
Though I turned on the Auto Brightness and set Backlight Timeout as Stay On, the display becomes dark in tens of seconds.
Then I turned off the Auto Brightness, set Brightness as 100%, and set Backlight Timeout as Stays on. But it's same, the display becomes dark in tens of seconds.
It's no problem at day time, but at night it's totally invisible.
I've tried this and that ways to fix this problem including factory reset, but the same happens.
I have used this device for around 1 year and there was no problem at all, but just after firmware updated around 1 month ago.
Anybody knows what would be the way to fix this problem?
