Hello,
I can't adjust my screen brightness. In Night mode the slider make no difference. Adjustments in Brightness in the Factory Settings doesn't change anything. A factory reset doesn't help. Is there a firmware and/or MCU update for this device?

Android Version 13
Kernel: 4.14.190
Build-Number: QCM6125 13 S10A_123 eng.hct.20250903.173632 EAU-V1
MCU: MTCHS_HA4Z_V4.16f_1
