I dont know what is happening. I tried to restart my mobile and it turns bright again. But it became dim after while.
Is this a bug? What I should do now.

Are you sure you havent got auto brightness on? This dims the display in different lights

Yes I am sure.

Ah, well, I'm out of suggestions then : )

After I go to sony, the problem still exists, does anyone face the same problem or does anyone know anything about software?

Does anyone know

This happened indoor or outdoor?
Do you have any screen protector installed?

i have the same issue.
does not matter if it's inside or outside.

Same problem here, I think sony design this to reduce the power needs when you turn brightness to Max. No such problem when in TWRP recovery.

[Q] odd bright flash when waking phone

I bought a new note 3 yesterday and I am noticing when I wake the phone I get a very quick bright flash of the screen before the lock screen appears. I believe the phone is trying to find the correct brightness level. When I turn auto brightness off the flash does not occur. Has anyone else seen this or could it be an issue with my hardware? any info would be greatly appreciated.
Hi,
I have the exact problem with my N900A as well. I don't have a solution either.

I think it is just a software issue with auto brightness. If I turn auto brightness off it does not give the bright flash. I wonder if alot of people have this happening or if its a defect.
Yes I only have that issue with auto bright turned on so I believe that's the cause

Is it showing any sign of life like turning leds on? Or its off? If its off then you have to send to Sony for repair.

check it in dark.if the screen light up in black it means maybe you can save it.if you cant see anything then you need to change it .And that sucks cause you will have to change the working touchscreen too.you cant change just the lcd

[Q] Screen on

Hey Z3c owners,
After an upgrade to LP-5.0.2, my screen acts weird. When phone is locked time to time screen comes on and does not turns off automatically, despite that my screen timeout is set to 30 seconds.
I have no idea what is causing that, thought that I could be triggered by notifications but after few test this idea felt.
Anyone has similar issue? Or any thoughts how to find whats triggers that screen on, and does not allows it to turn off?
Thanks

From what you are saying it looks like a hardware problem. There is nothing from the software you can do to fix it...
I'm very sorry but you need to take the phone to a repair center.
Thank you

screen brightness problem

Hi all, my p30 pro, when the screen is woken up in the bright sun, it goes to max brightness. However after about 30 seconds the screen dials back the brightness to about 75%, and even if it manually move it back to 100%, the screen doesn't get any brighter. I have tried all the setting regarding the display, manual, auto, vivid etc. I have factory reset the phone as well. Any thoughts or ideas please?

Unfortunately no, I am still using it. But it is almost unusable under sunlight. Was hoping a software update fixed it, but no luck.
I forgot to ask what software version are you on and when the problems started.I have a mic problem too and I already changed the mic but although it's a bit better it's still not usable as before.
I am on emui 12. Can't remember when it started.
any solutions? on the newest version of the software my display doen not adjust automatically to the light outside. I do not even have this option. When I try to restore to the previous version by the hi suite I get a message that I have a problem with my Internet. I dont know if it worked on the previous one . I got it and installed the newest version. Any ideas?
