Coming from a Z3, I am disappointed by the adaptive brigthness. Whereas it used to work nicely on the Z3 (set up to 30%), on the Z5, with the same setting, the brightness turns to the minimum when the phone is used indoor with artificial lighting, so bad...
The brightness is fine all the day long (30%, adaptive on). It's only coming home at night (or anywhere with average light like a restaurant), the brightness turns to be too low. Thus the screen is not flattering anymore at all...
