Pathetic flashlight performance on e6683 - Xperia Z5 Q&A, Help & Troubleshooting

My college dorm had a blackout, bored waiting for the light to return we eventually had a competition to see whom have the brightest phone flashlight. I noticed, the flashlight for the Z5 e6683 is warm and pathetically dim compared to cheaper mid to low tier specs phone such as Galaxy J5, IPhone 6, and an Asus zenphone.
paying a premium price of RM 2700 (it's my country currency) for the phone, this is an utter disappointment

First could u pls send pic...
Did u use built-in flashlight app or another app? (which app)
also u can test flashlight with this app >> Turn on as Torch

:good:

Yes the torch is very dim on the z5, mine is the E6653 but it is almost too dim to be useful outdoors at night.

Noticed the same thing, it's very dim compared to my old iPhone 4S, Galaxy S3, Note 3 (the brightest I've seen) and OnePlus One. I don't know how it affects the pictures quality, but it sure isn't very good when you want to use it as a flashlight

Built-in flashlight from the notification pane, did tried a few apps which supposedly makes your Flash performance "better than ever" but to no avail. I get the same results, even worse on some

Presumably as camera technology has progressed and sensors become more advanced we no longer have the need for such powerful flashes. Hence the torch isn't as powerful, as it's only really a by product of the camera.

@moonbutt74 Could you share your results with the torch ?
or just simply the changes to /sys ? (echoing values)
It's pretty bright, no ?
That should give another incentive to use CM-13.0 and custom ROMs
Thanks

Currently [see what i did there? xD ] 80 seems a fair value as max, i tested as high as 160, but that seems silly, my interest is a decent torch without heavy chewing on battery life so i set my own build @ 60.
Haven't been able ti fond the class in stock so i don't know the stock value off-hand.

Hm, okay so 60 or 80 is a good starting value,
The folks want it bright - they can get it bright (up to 160)

@KIMI_
if your phone is rooted you can write a small script and launch it & play around a bit to see how bright the LED can get,
all modifications or changes on your own responsibility though
Argh - all thanks used up again ...
Enjoy

Hi guys, I don't know if you still care, but I figured out how to fix that annoyance. The downside though: root is required.
in "root/system/etc", there's a file named "flashed_calc_parameters.cfg". That's the file you'll want to edit (and please, don't forget to do a backup before editing it).
It contains many different values allowing you to control the brightness of every LEDs (including the notification LED), but the 2 most important values for what we want to accomplish are:
if_torch_vr=
That one changes the Torch brightness (flashlight, when you record a video, etc.)
max_if_flash=
That one changes the camera Flash brightness (when you snap a picture)
If I'm not mistaken, the default value is 80000, and the maximum allowed is 500000 (I wouldn't use that value for an extended period of time though because of overheating concerns). At the moment, I'm using 250000 for both (Torch and Flash), and trust me it makes a BIG difference (and probably is the best battery life/heat/brightness compromise)

Is it possble to edit torch-light power on the go, without rebooting?
Do i need modded kernel (from moonbutt)? The command you posted involves /sys/class/leds/torch-light1/brightness, which seems not available on stock roms with stock kernels.
Thanks

Hi,
I haven't looked into the interface for the stock kernel,
also haven't been on Stock for a long time - you could however grep for torch or flash if there is some kind of value that can be edited related to it
e.g.
Code:
find /sys | grep -i torch
Code:
find /sys | grep -i flash
Thanks

On Z5 compact default torch value is
LED If setting for Torch or video recording (uA). if_torch_vr = 25000
I noticed that i can increase it up to about 260000 (more or less the stock value for camera flash) but if i go over it, like 300000, after less than 20 seconds the phone switches off saying "Shutting down your device due to high temperature". But the phone isn't even warm....I don't know which sensor is triggered (maybe camera sensor) but this proves that the thermal engine of the Z5 line is VERY efficient in its work.
However, setting it to 250000 really boosts torch light but for me it's not enough: i'd like to get the flash power of my 4 years old Samsung Galaxy s2 which simply outclasses the Z5c flash light.
Maybe playing with thermal-config would help in this matter, if i have time and get the right knowledge to do it, taking my risks i could try.

app to increase brightness ?

hi,is there anyway u can up the brightness level on these phones its up full at the moment but still could do with being a bit brighter
Afaik you have to wait for custom roms to get that up'd
Regards Dousan...
e: maybe its enough with a custom kernel...
Well the screen is not that great on our phone which is why we get around 2 days battery life with average use even I would like the screen to be brighter but it will greatly reduce battery life

Have you tried installing dazzle? This app has some niffty display controls for maxing out the brightness.

it all comes down to the fact SE does not allow us to disable auto brightness so even if you "crank" the brightness you still have to live with auto brightness controlling the brightness while settings 1 2 3 on the power control widget appear to turn it up it is still being controlled to an extent..

Will probably at least take a recompile of the kernel.
An answer to this question is in the Arc section, from SE:
A question on how to disable auto-brightness on Xperia PLAY.
Unfortunately, being able to do this from userspace might be non-functional in the released kernel for Play. The engineering team is aware and it is something they are looking into for future releases, can’t comment if it will be supported though yet.
However, if you’re building your own kernel, you can modify the file arch/arm/mach-msm/board-semc_zeus.c
What you’re looking for is the structure “as3676_platform_data”, where you can change the “als_connected = 1” to “als_connected = 0”.

I'm not sure how this would work, but there is a parameter
in /sys/devices/i2c-0/0-0040/leds/lcd-backlight/als/ "enable" which by default is set to "1"
Might want to test something like
echo "0" > /sys/devices/i2c-0/0-0040/leds/lcd-backlight/als/enable
You need to be root to do this

News for brightnes controll ?

Increase Screen Brightness beyond normal or "stock" values?

I really love my Inspire, especially w/ Honeyogen installed. But the problem of viewing the screen in direct sunlight is a major problem for me, one that I cant seem to find a soultion for.
Ive tried different screen covers & different ROMs & even different Kernals, yet the Inspires Slcd screen is still terrible in direct sunlight, as all I see is my reflection.
My question is this... is there anyway to hack the screen to increase the brightness beyond the "normal" or "stock" brightness levels?
I would think that if developers can hack volume levels for the external speaker & also freq values for overclocking the cpu, that the same could be possible for the screen brightness!?
Thanks, i appreciate your thoughts!

Thank you for this question. I am interested in a solution to this as well.
is your screen on auto brightness? take it off and adjust yourself. it will adjust to light depending on how much and how little you get.
If your rom is cm7 base go to menu, settings,cyanogenmod settings,display, automatic backlight,scroll down to light levels,check use custom, other levels, (this is what I do) change 1st 3 screen profiles from 41 to 61, 61 to 81, 81 to 101, then hit save and apply. The higher the # the brighter the screen. Those settings are pretty good on battery and definitely helps on making the screen more viewable outside and in bright rooms. Hour this helps

Thanks for trying, but of course I've set my brightness levels myself. Auto-brightness doesn't do it for me.
I'm just surprised that there aren't hacks for screen brightness. Just as speakers levels & the CPU are governed to a certain threshold in stock configs, I would think the screen is governed and has much higher brightness levels it can go beyond.

Yes, my ROM is CM7 based. But I assume these custom levels are for the Auto-Brightness mode?
Also, where exactly do I make these changes? Because the "screen" values are already at 41, 61, 81, 112 and so forth. So I assume these values have been changed by my ROM developer or are they CM7 defaults? Or do I have it all wrong? LOL. Thanks again.

Yes, this is for auto brightness. You do have the correct defaults. I bumped the first 3 profiles up by 20 and screen is brighter at lower levels.

Ok, but my question is does this actually make the screen any brighter than the highest stock brightness level?
Or does this just change the values, so that the lower values are brighter, but no brighter than the stock highest level?
no brighter than brightest stock value
Sent from my Inspire 4G using XDA App
So why can you developers increase & hack the speaker and the CPU values and MAX out their potential, yet the screen's potential is wasted and we are stuck with dark screens that can't be seen very well outdoors?
It doesn't make sense to me. The screen backlight must have more potential, they don't push ANY hardware to it's max in stock configurations.
Come on developers, we need you again!
FALSE - juice defender's ultimate (maybe even pro) app can adjust it higher than the 100% brightness value. Only problem with this is that you have to let it control your brightness settings, but there's a bug that doesn't allow you to install apk's manually - so you have to disable the brightness while you install apks (or you could just install through adb lol). so yes, there is a way.

Um no Juicedefender does'nt raise the screen brightness ANY higher than you normally can w/ the stock brightness slider. All that does is mess with the Auto-Brightness settings.
Alot of people seem to get the Auto-Brightness settings confused with what I am asking. I want to be able to raise the brightness beyond the MANUAL brightness slider. If you raise the auto-brightness setting, your STILL limited to the max value that's on the manual brightness slider. I want THAT manual setting to be pushed beyond the normal "stock" value, which I guess is impossible......can't understand why when almost every other hardware is hacked to allow better performance.

Okay sorry just looked at juice defender again. It allows you to only change the shape of the brightness curve. As for forcing a brighter screen level I'm blank on that. Have you manually set it to 100% and its still. Not bright enough?

You cant overclock the values of your android hardware "screen" for brightness and dimness since it can only work properly on a given threshold hence any more than that is negligible.

Lower backlight

I've looked around and haven't found much, hopefully my Google skills aren't weak.
Other than using a screen dinner app, is there a way to actually decrease the backlight further? I can do some more complicated stuff like decompiling apks and what not. I just don't know if there's a way to make the range of auto brightness much lower.
I use my phone a lot at night, and turning the screen on is like getting punched in the eyes, andwhile I'm using it I feel my eyes strained.

try an app called lux. Its not free, but it did wonders for my battery life
Another option is JuiceDefender Ultimate... you can tweak the response curve to obtain lower brightness levels in low light conditions... it has a ton of options.
free app called screen filter, does what juice defender does, but its free. and it goes REALLY low .... to the point you will see "blots" of dots on the screen

Screen Filter just puts a filter over what your phone is displaying instead of actually physically lowering the backlight. It makes things look odd (to me) and it doesn't actually do anything for battery life unless I'm mistaken.
I mean something that actually allows you to lower the backlight further.
technically speaking becuz it's putting a software overlay on, the phone physically uses less power, so they do work. You lose some contrast between certain greys and farms though. I highly recommend u look into the "Lux" paid app I was telling u about. Its the way auto brightness should be, with user accessible custom config. The author is so good that if at anytime u decide the software isn't for u, u get a full refund, no questions asked, even if its a month after, let alone a couple minutes past the 15 min return period

I'm not sure what you meant by becuz it's putting a software overlay.
I have realized that having the screen darker (even just displaying a darker image, like what Screen Filter does) uses less power because of the way that our screen works. On an LCD screen however, it would actually use more power.
I'm trying lux out right now, it seems promising.
when you use the term "physically" i take it as you want a PHYSICAL mod to the phone; good luck with that. Screen filter does me just fine, it does the same effect as many other "battery savers" do.
any apks, apps, etc are all SOFTWARE mod to the display screen / brightness. You are venturing into a world of unknown if the apps aren't appealing to your taste.
Keep in mind, the SR is S AMOLED, not just a regular LED / LCD display.

No. By physically lowering the brightness of the backlight I meant that....well the intensity of the backlight is actually physically lower as opposed to seeing everything through a grey mist (how I see the screen filter thing).
Also, try to contribute to the purpose of this thread instead of insisting screen filter is good when I've specified that's not the solution I'm looking for.
Speaking of useful contributions to the thread..
Lux is really nice. I like it. I can't tell if the sub zero brightness is the backlight actually being PHYSICALLY (by means of software, don't worry) less bright or if it is using a filter where I just can't tell. Either way, if I can't tell then it's not bugging me. Thanks for the tip, after a day of setting it up and whatnot it's really nice.

.uhm.... don't be decieved by the name "screen filter" ; that is just the given name; the method of adjusting brightness remains the same as many other "filters" and "brightness" controllers.
Searched "lux" on the market and a lot of them have poor reviews, screen filter has over 9,000 5-star reviews so I'm pretty sure it's working...
You try screen filter and drop that "filter" below 20%; so if it's not the "brightness" being adjusted? what is being adjusted? color? gamma? contrast? sharpness? color intensity?
Again, I'll let the reviews speak for themselves; my main point is, SOFTWARE = SOFTWARE. Android is the system; the software manipulates the settings of the system... so unless Lux is somehow hacking unknown system values / physical hardware, software = software.
Another vote for screen filter by me. Period.

I'm glad that you are using the reviews for random apps with the name lux in them as grounds for proving your point. Just in case if you care (which I doubt given your hostility) the app that I'm using is Lux Auto Brightness. Very nice.
Oh, and don't worry. The reviews give it a 4.4, not as good as screen filter but that doesn't seem to me to fall under 'poor reviews'.
Again, I wanted to lower the BACKLIGHT. Which, in turn, means a lower brightness. I wanted an app that would allow me to decrease the physical brightness of the backlight. How can you not understand this? Screen Filter does not do this, it puts a filter over the screen.
It even says, right in the description for Screen Filter "Applies a shade that acts as a dimmer to ensure your eyes don't hurt."
That is NOT WHAT I WANT.
Lux Auto Brightness actually does what I wanted - it allowed me to lower the backlight even further, making my phone less bright WITHOUT putting a filter/shade/softwarewhatever over the STDOUT. Goodness.
Also, thank you for specifying that software = software, I have no idea what kind of mess I would have gotten into without knowing that.

Cm7 Automatic Backlight Settings

I wrote down 2 pages and hit post but xda logged me out and now I'm really, let's say it, mad
Hello everyone.
Shorter version:
CM7
Pros:
1. Amazing battery life.
2. More options and settings (after all it is cm).
3. Nicer user interface.
4. Flash player 11 for arm6 is working perfectly.
5. No bloatware.
6. Fast enough and stable (not one fc so far).
Cons:
1. Front cam. Although back one is working fine it would be nice to have a front one as well. Minor issue though, I don't use it anyway.
2. Fm Radio is always turning my bluetooth on when I start it and use it. Don't know if it is supposed to do that but it is a real battery drain and I don't want to use 3rd party apps if that is even possible. This is a minor issue since I don't use it often.
3. Led notification turns green at 90% and more when charging and my phone tricked me to unplug quite a few times Also a minor issue.
4. Default automatic brightness is just terrible. I know that they can be modified through cm settings>display>automatic backlight but I am not sure what values to enter to get the best and optimum results. I just cannot get them quite right.
So, to conclude. Cm7 is just great and really ready for daily use. I only need to set up the automatic backlight properly and this is where I need your help. If anyone knows the best values for these settings, please, write them down in this or the original cm7 thread.
Best wishes
I've set the status bar notification for backlight to 25/50/75/100. I feel that these values suit every possible condition.

Hi Alex, you must have misunderstood me. I'm not talking about those settings. I don't want to adjust brightness manually. I'm talking about window length, reset threshold, sample interval and custom light sensor levels so my phone can automatically adjust brightness. These can be found in cyanogen settings>display>automatic backlight

Ah, ok then.. Unfortunately I did not have the patience required to set/tweak them.

Screen dimming app.

If any of you other users out there feel that the whites on this thing are too awesome for super late at night like I do, I found a app when searching for a f.lux type alternative for android. I have been using this app to help ease the stress on my eye late at night. I dont know about the techical side of what it does, or any of the jargon involved, but it applies a filter of sorts to dim the screen further than what the phone allows. I been using it a lot lately and figure I would share with you guys. If anyone has any recommendations for other similar apps, please share.

Or just turn on "Background Color" in Power Saving Settings.
Or if you want the screen brightness itself to be lower than what most ROMs allow, you can use this app called RootDim. It worked amazing on my xoom, not sure if it works on the SGSIII yet..
It requires root though..

Screen filter does the same and doesn't require root. On our AMOLED screens this can save battery.
Also you can turn off those damn capacitive key lights by going to Settings>display>"touch Key light duration"> Always off.
I can confirm that Root dim does work for the SGS3 I use it on my phone.

Lux is an amazing auto brightness app and setting it up for your tastes is incredibly simple.
Go out in the sun and turn brightness up all the way using the app then "link" that setting, go in complete darkness and set it to your taste and link it, then indoor lighting, set it, link it. It then uses just those 3 settings to create a smooth graph of brightness values that are all perfect. You can have as many links as you want but i find the less settings you put in that app the better.
I tried all the suggested ones in here btw.

I've tried and really like Lux (in fact I'm considering purchasing it soon) but I've noticed two issues. First is that sometimes it will not refresh itself and I have to open up the lux dash to get the brightness to change. It doesn't happen often, but it happens often enough to be annoying, and I have it set to automatically.
Also, (and this may simply be an issue with the S3 and not lux itself) but sometimes I will be in a decently lit room and be at 1 lux, while lights out is 0. Not a lot of variance unless it's really bright outside. Have you found anyway to increase the light sensors sensitivity?

Try setting it to be always active in the task bar, that prevents it from being killed. Also try setting it to not use raw values for light sensor readings, this gives you a simple scale of 0-10 for readings and total darkness always reads as 0.
Edit: oops reread your post. That's weird that it is reading indoor light at 1. I usually get around 2 or 3. I used to have a screen protector on that covered the light sensor and that put it all over the place. Maybe that is what's causing it?

I noticed the same behavior with the free version. In my case, the lowest value the HTC Desire S can reach with its default Android auto brightness is in fact about 15%.
In LUX settings you can configure the "0" value to be lower and "bypass" the freeware limitation (you can't configure sub-zero levels in the free version). This will work when you test it in the dashboard, but during regular use the light level never goes below the 15% limit already set by the OS.
What I did was purchase the full version (to get astronomer mode along with all the settings unlocked) so I was able to leave the 0 level at its default 15% but link some light intensity values to sub-zero percentages. Guess what? It works great! Once you go into a very dark room, the display dims as far as you set it to.
Another problem with the free version was that a few times I unlocked the phone outside in full sunlight and LUX did not increase the brightness. It appeared almost completely black because the light level was at about 15-25% (the same level it would be inside a low lit room).
Again, with the full version I did not notice this problem (I've used the free version for 1 day and the paid version for 1 day but running tests in different light levels inside and outside).
It's like the free version is a bit buggy on purpose, and I remember uninstalling LUX free about 2 months because of this; I was thinking that if the free version does not work OK, I shouldn't buy the full version. Apparently this is not the case (touch wood).
Just for the record, it's on "dynamically adjust".

If the display is a bit dirty (oily, dusty, etc) around the light sensor, you can try to clean it. If this is not the case, open the dashboard, let it determine the light level or hit "auto" a few times and make sure the reading is correct. Then just slide your finger along the yellow line to find the appropriate brightness level and long press the chain to link. Go to a brighter lit room then go back to the first room and see how LUX behaves. Also lock/unlock the phone a few times and see how it goes.
If you still have problems running LUX, disable it and check the default Android auto brightness to make sure it's not a sensor issue.
LUX also has the possibility to set the response delay under Settings -> Advanced -> Developer Settings (the last to just on the bottom, but for this you would need to buy the full version.

Thanks, but I think it is more of an issue of the sensor not being sensitive enough. I'm not sure if this is anything you can change in lux or if it would have to be edited in the kernel (or if it is fault of the hardware) but I just feel like the sensor doesn't go down low enough. As I said, I can get down to 1 or 0 in a decently lit room, and yes I have tried cleaning the screen. It's not like it jumps around or anything so it's not like I would notice anything in default auto brightness, it's just that it doesn't seem to be sensitive enough.
Screen filter is great!! I use as well!!!

Well for my Desire S, the lowest light level that the sensor can read is 160 lux (raw value). You can try and set LUX to use raw values because this is more accurate in my oppinion.
Another +1 for Screen filter here
Does anyone know how to use "luma" values for automatic adjustment in Lux instead of "lux" values?

What I have noticed on my phone is that "luma" readings are taken from the front facing camera, while "lux" readings are taken from the ambient light sensor (you can chose which one to use in the settings).
I suppose the front facing camera uses more battery than the light sensor; it also appears to be more sensitive because it can read more light levels.

I guess so. Thanks! But doesn't that kinda defeat the whole purpose of Lux? Because you can't use automatic mode with the camera(s).... so then what's it good for?
Well even if you don't have an ambient light sensor, you can still use the camera to check the light level when you unlock the phone and let LUX adjust the brightness level. Of course it's not dynamic but it's still better than having the brightness at 50% the whole time or changing brightness levels through a widget..
