Sony Xperia SP screen/ambient sensor not working

[amiltonpueljuni]

Hey guys,

Just got a brand new C5303 phone, and the screen does not adjust properly.
If I go out under the sun, cpuz will read 1023 lux, wich I suppose its the max limit, but the screen back light will not be at its maximum. For that, I need to activate the back light option. Any ideas on how to solve that?
That option to adjust automatically is on.

Yea me too.I previously had Nokia C6-00,got  QWERTY keyboard.Types 400% faster than the Xperia SP.But in the downside it doesn't have GPU for 3D gaming 😕

I mean before the phone really locks, when the power button is pressed and the screen is turned off, if u press volume rocker or camera button it will turn itself on again, that's what happens to me

If the phone is locked pressing those buttons won't do anything (except holding camera button).

Kinda complicated.Did you altered any in "Developer Options"?

[amiltonpueljuni]

Nope. When I press the power button, the phone isn't locked, it just turns off the screen. 2 minutes later it locks by itself.

Before those 2 minutes, if I press volume rocker or camera button the screen is turned on. That's the problem, because that happens inside my pocket.

Ouh.Thats dangerous.As far as i can see,nothing that i can do except hoping that the 4.3 update will solve the issue.

Wait wait,i got the solution.First,go to Settings->Security->Tick "Power button locks instantly"
Hope it solves your problem.

thanks for the reply. Unfortunately that doesn't really solve it, cause then I'd have to unlock the phone 500x per day, that's why I've got locking screen only after 2 minutes

Sorry my man,can't help you.I know that you need to unlock it frequently at the same time not unlocking it by accident Hmm,i think Sony might solve it in 4.3 update.
