Hi,
I just wondered if there is any way of increasing the brightness of the torch? It's crap.

it is posible but i havent tested at all to see if its safe
I got a prototype mod for increasing the LED brightness, but I'm not going to release it. I think it significantly decreases the LED's lifespan.

ill be testing some more when i can however its very dangerous for me as i wouldent be able to aford a repair or a new z2 for a very long time
@Jackos
i descovered the LED hates voltages being too low, (same goes obviously for too high)' it doesnt dim down but it just doesnt light up
i also descovered the LED gets hot as it is being on for about 1-2mins

I think that overall it's a low quality LED.
Well, if you burn that LED, you can still send your Z2 for a warranty repair

i found i had no problems after lowering brightness, heating is gone totaly but it was less bright, ive lowered brightness in my rom but im going to make the flash for camera alot brighter, perhaps stock or more by a tiny bit
Increasing the brightness of torch can be harmful for the Hardware as it may overheat and cause problems with the Camera.

wont do anything to the camera, it will damage Led light only

I read that somewhere when I was searching for same topic.

they are seperate units with their own information.
the camera app has control of the LED flash, the led flash has its own settings in the system which determines its brightness and voltage.
the camera hardware does not have anything to do with flash aside the flash assisting camera use.

So I just noticed there is a red LED on the phone, However I've only seen it enabled whilst in call (Am I the only one who hasn't noticed it before?) So anyway, I'm curious to weather someone would be willing to go about and help trying to be able to have it on when you have a notification, Or if there already is a mod? Anyway, Thanks
That's a proximity sensor, not led

It's a proximity sensor,this sensor ensures that the screen turns off when you are in a call.
Oh Damn, Dissapointed Would you be able to have it on anyway? But I guess it'd kill the battery?
That Red LED is barely noticeable unless you are in complete dark!

I have SE LWW i love this phone but what i have notice that it has some problem with the sensor that change the brightness according to the light conditions.
What happens is that sometimes the screen start to flicker that is continuous jump
between low and high brightness which is very irritating.
So please share if any one of u face the same problem or know anything about it.
I m using LwW from yesterday but havnt seen this kind of issue may be needing more time to cross check, will update definitely.

yeah mine too.
i think it's coming from the device light sensor, n we can't fix it until sony put an update.

Weird had the lww too and never had that problem. Do the ones that have it updated your phones?? I am currently on lasan's rom but never encounter it.
thanks for replying guys but i think it is the ambient light sensor problem that means it is a hardware problem so it might not get solved by update.
Be positive most of the times it is a kernel related problem or take to a service center and see if they give you a new one
Live With Walkman
Live with walkman has a ambient sensor in it which changes light accordingly
but i never noticed any flicker in my phone my suggestions would be take the
phone SE service center
the flicker shows when u look at screen from side. but from infront of the screen, it's hard to see.

I confirm this.
When brightness is not full(I used on half on Stock and Hybrom ROMs), then in some conditions the screen indeed does flicker a bit.
That is caused by ambient light sensor, which detects many different light levels at some point, that is the reason for changing screen brightness so much at that time.
Currently, I am not aware of solutions for this, as I do use custom ROM, where I haven't noticed it yet.

I my case the flicker is noticeable from front also.

Is not a bug, most other phones have it also, that means light sensor works.
It shouldn't damage your phone.

Go into Settings -> Developer Options and make sure "Show surface updates" is not ticked... what you are describing sounds a lot like it is on.

Sounds like brightness is set to Auto. Set it to manual and it should stop doing that. But you'll have to change it if it's too bright out or if the screen is too bright inside. Not usually a problem for me, I keep mine pretty low all the time. Saves on battery too.

I did these things.
my friend change LCD of phone
and say this problem is not for LCD or touch
just say it is for sensor maybe !!
and i change the Rom and other works but not resolved

no body ??
Sorry... Got nothing, you covered every possibility I can think of besides hardware failure, since you turned off auto brightness that is the only sensor that would be involved. You mentioned the panel was replaced and this occurs when you touch the screen, possibly a bad/loose ribbon cable to LCD panel?

Hi everyone.
I love the TrueSmart but I've got a problem with the screen.
There's a flicker on it. The whole screen flickers and it's particularly noticeable when the background is white or any other light colour.
Has anyone else experienced this and what are my chances of getting it fixed or replaced under warranty?
Thanks for any advice in advance,
HRH.
sounds normal, mine too

FWIW mine does not, at least I've not noticed it - recent batch - does screen brightness setting have anything to do with it?

Now that's a helpful comment. Thank you. If I set the screen brightness to maximum then the flicker goes away. Not ideal, as I've never set any device to max brightness in my life. Never needed to. But at least the flicker goes away.
I just hope it doesn't make the rubbish battery life even worse.

Ah. I was thinking more in terms of down rather than up (but I didn't say so...). Indeed, it's bright in the first place and raising it will probably have an impact on battery life.
I think Lokifish reported some time ago that the screen was ridiculously over bright even at the minimum setting and that there was no change in brightness if raised over 50%.
I used Lux on mine to drop the brightness way into negative values. I have noticed no annoying flickering, but there were early reports of nasty flickering on some samples back last Fall.

So I, at first, thought Assertive wasn't working/enabled on my V20 but it turns out the stock settings are just pathetic. I spent some time adjusting the config file and had a few fellow V20 users test out my changes and they have all reported back that it works fantastically now.
For Assertive to function, your phone MUST be set to 'automatic' backlight control.
Decompress and copy my file to your phone and replace the calib.cfg located in /system/media/display/. Make sure to change the permissions on the replacement file to 644.
Reboot and enjoy
Test out in direct, bright sunlight. You'll be surprised.
Let me know your results in the poll and in comments.
Thank you for your work brother
what does this do exactly?

Assertive Display was designed by APICAL. They are owned by Qualcomm and Qualcomm has built the tech into their SoCs.
Basically, it adjusts the gamma curve, white balance, contrast, etc. of the display based on intensity and amount of ambient light. It can take a display that would be utterly crushed by sunlight and make it readable.
Try it out.
Colours get really washed out in the sunlight but i can see the screen better

The problem I have is in low light environment. Screen goes to zero as soon as the light gets dimmed. I can't think of any environment that I would want the screen at zero. That's just too dark for my old eyes

Tap the light button in the pull down status bar. It corrects this issue. (Right above where it says 68%)
