facing the same problem, Infact I was going to start a thread on the same issue.

It seems the phone doesn't have an ambient light sensor.

I used some hardware info apps and they all confirm it. I suggest you too to check once.

but sony's xperia u white paper claims that it has one.

Please comment on this, Xperia Support Team...

try to run some test
dial *#*#7378423#*#*>service test>ambient light sensor, cover the sensor or flash a light to it. does the values change?

[MarlonUk1]

you can observe the ambient light sensor more if the screen brightness is not set to max.

It shows ony this

     Ambient Light Sensor

          value:0

do you have xperia u and see something different?

[MarlonUk1]

it does not change even if you put it on direct light?

[pradeeprk4]

ya, too dark or too bright , it stays still.

[MarlonUk1]

well technically it would be a hardware glitch,

I would suggest to perform a factory data reset or repair with Sony update Service

if that does not help, Please send your phone to a sony service center near you.

did you put another screen protector? or is there something blocking the sensor?

only the one which is provided by sony (in the box), not any other.
