[Q] SGS2 Eye Strain - Galaxy S II Q&A, Help & Troubleshooting

I have ongoing problems with eyestrain. Back-lit screens seem to be the issue. Have you found the SGS2 better or worse in regard to eyestrain, if this is an issue for you. I would really like the SGS2, but I may go with the Sensation if its screen may be better for me. Is max brightness on the SGS2 bearable? Reducing brightness seems to increase flicker on LED screens.

Does the job very nicely,

Regards.

Is it possible to keep SGS2 brightness at max and then use this app on top to make it appear darker? Or is Screen Filter just a replacement for the SGS2 brightness control that allows further dimming than minimum, or does it work differently?
Thanks

I havent noticed flicker on the S2's screen on normal usage unless I open up specific test patterns for flickering like this site
http://www.techmind.org/lcd/

It of course is to dimming it over min brightness for easier night reading without any sort of strain, haven't used with Max brightness as even 25% is too bright for me for normal usage and then that app with Auto brightness for night readings/browsing
Regards.

Oh. I thought maybe it worked differently since on the app description it talks about applying a "shade" over the screen.
It might work for me if it did not actually dim the LED, but "filtered" the information to be displayed so that it came out less bright. I don't know how exactly that would work, and I guess if this "software" dimming was available then manufacturers would already be using it.

I've decided to go with the HTC Sensation. I figure that the SGS2 will either be the worst or the best phone in regards to eye strain, and it's not worth the risk. Kind of bummed out since I had my heart set on the SGS2 but hey everyone keeps saying that they're both great phones.

Both phone are great but i dont seem to experience eye strain on sgs2 seems good to me...imho

A suggestion to help with battery lifel, not cpu or radio related

Problem: For most of us, the big, bright screen eats up most of our battery power. One advantage of LED screens is the darker you make them (including using dark backgrounds), the fewer milliamps they use. So you could turn off auto-brightness and manually adjust the brightness to darker settings. Far from perfect since you must adjust it every time you go from a dark building to a bright sunny day - and vice-versa. A pain.
I recently installed Screen Filter by haxor industries. They only tout its ability to make the screen really dark for night-time viewing, with the side benefit that it will also save some battery. It works great for that. It will make the screen much, much darker than the lowest stock brightness level (even using apps which take it to its absolute lowest setting, which the stock brightness slider won't allow you to do). I've found going to 25% is perfect. It makes the screen a little gray when you go really dark but its a minor downside.
Solution: I realized it can also be set to only dim the screen a little, like 75%, or 80%. Not helpful at all in a dark room since it is still very bright. But I also noticed that it works along with the stock auto-brightness setting. So you can apply a fairly bright setting to Screen Filter and leave it on all the time, effectively lowering the stock auto-brightness level a few notches no matter what brightness it picks. You still get the benefit of auto, and you get to reduce the battery draw all the time, on the single-biggest battery user on the Note.
You can save multiple widgets on the home screen, each set to different levels, so you can turn off the 75% setting and apply a 25% setting at night with two button presses. Or turn it off with one button press in bright sun. And/or you can add it as an app shortcut which allows you to adjust the brightness from an "ongoing notification" in the notification bar.
I'm starting a test today, leaving mine on 75% all the time with auto-brightness on, and using 25% in dark situations which doesn't happen often. I expect this will produce a noticeable improvement in battery life.
are you representing the app ?...or for the company?......

Look at my post count and how long I've been on this board. No.
The app has no ads and is free, BTW.
Looks promising. Ran mine down to 5%. 15 hours on battery, 4 hours of screen time. Most people here only report 3 to 3 1/2 hours of screen time.
I just maintain my brightness, im anal like that. Especially with that notification shortcut for increasing or reducing brightness someone recently posted. i am good to go.

I use screen filter and did not think to use it all the time with auto brightness, I will give it a go thanks for the idea.
Simply setting my brightness down to about 25% and leaving it I get 4.5~5 hours screen on time.
This is still working well for me, with a noticeable increase in battery time.
I've adjusted my lowest setting from 25% to 30%, too much of a gray cast to the screen at 25%. 30% is still pretty dark in a dark room. The 75% setting is good most of the time but I've found in full sun I usually have to turn it off.
Lol at wish777, ya he is promoting a free app. Do some research before you assume and accuse someone of something.
Thanks to op for app suggestion, it works great. I downloaded it, you must of brainwashed me with your deceiving free app propaganda

Yes, the screen is almost always the biggest battery hog in these devices. Thanks for sharing that app.
Here is another, https://play.google.com/store/apps/...XJ2ZWZpc2gud2lkZ2V0cy5icmlnaHRuZXNzbGV2ZWwiXQ.. It is FREE, so no acusations. I am not the dev and I didn't even play one on TV. This one is nice because you have a single widget that pops up a window with several options of screen brightness.
ANd if you are using Juice Defender Ultimate, There is Brightness feature built in that do the same thing.

Looking at the reviews for that app, someone said that Dimmer takes the screen down farther. I tried Dimmer before Screen Filter (only for night time viewing) and can confirm it will take the Note down to the lowest allowed 10/255 where the stock brightness only allows you to go to 30/255. However, Screen Filter will make the screen even darker than Dimmer. Something to consider - not bashing any of the above. Just sounds like Screen Filter is better both for daytime and nightime use.
I use screen filter to read at night. I'm not sure about the battery savings but with screen filter set at 12.5% the screen is unreadable unless you are in a dark room. In a dark room at that level white text is more gray than white as well.

good thread. i installed S.F. in Feb, def works great for me. but i prefer manually adjusting screen brightness via the shortcut "Slider" at top of the Gnote's screen
I use this app for night time reading. It works great and I didn't know about having multiple widgets with different darkness settings. Thanks for the pro tip!!!

I'm getting just shy of and over 4 hours screen time, depending how long I'm actually talking on the phone for that day. Not using this app btw, wifi at home, LTE everywhere else
Actually, for me, the screen is the number 3 item for killing battery, trumped by phone calls at number one. And I dont even spend that much time on phone calls, usually less than an hour per night (I wish I could find a solution for this besides not making / taking calls).
Under Settings->Display->Auto Adjust Screen Power, I have this DISABLED.
This helps significantly with the 'greys' on a dark screen (to the best of my limited comprehension, this is being called black crush?) AND virtually eliminates the 'banding' I was seeing initially. Strangely however, I had to disable this option and it took a day or two before the banding almost completely disappeared (I was seeing it ALOT on the Google Market initial grey screen before it loads in the ads).
I use Auto Brightness.
I also have Settings->Power Saving->All Options are DISABLED.
Anyway, you might try disabling the power saving and auto adjust screen power and see if that helps with black appearing grey using the app you are mentioning.
Use the 15 toggle mod to turn of all cellular data when you don't use your phone. You can still receive messages/calls but there is no reason to leave mobile data on while at work or you're not using the phone.
I usually leave school with around 90% battery left and I'm on school from 8-1. All because I leave data off while not in use.

[Q] Auto brightness or max it out?

The screen dims and changes brightness by itself so much I am contemplating just turning it up and leaving it.
Any thoughts to this, and does it drain your battery super quick?
Seems a waste of the SLCD 2 to have so dim and changing brightness all the time

If you plan on disabling brightness just keep in mind if your an outdoors user or indoors user, the lighting around you will play a key roll on what levels of lighting you decide to have.
Personally I have the Automatic setting enabled, but I keep a widget (via widgetsoid) handy so I can disable it when I want and how I want on the fly.

Max brightness will definitely have an adverse effect on batt life. I personally keep mine at about 40% which is fine except when im in direct sunlight.

I know what you mean, I tried doing the same because I got sick of the brightness changes all the time, but after a couple of days having to adjust it myself or compromise on batt life, I decided to go back to Automatic settings... In my life I go to much outdoors as I can spend hole days indoors its what ever happens, happens so I decided to stick with the annoying setting other than being annoyed by having to set it myself.
Screen brightness is the biggest contributor to battery drain. I keep mine as dim as possible at all times. I've unfortunately become quite OCD about it.

I'm the same way. But the problem I have with this phone is that the more dimmer I make it, the more uglier the whites become (which I have become OCD about).
So I have double OCD working against each other and my brain is going to explode. That is all. Carry on.
Ok; the phone has been out a few months. Anyone's opinions changed?
I generally keep screen auto-brightness OFF, and set it to about 60% to 70% brightness static. When plugged into power to watch video, I go to 100%.

+1 for Auto and a widget. Most of my use happens at the extremes - OFF or 100%, so this provides easy switching.
I keep mine down around 10%, and only use autobrightness when outdoors

[Q] How is the sunlight legibility?

Hey guys, im getting a good deal on this phone, and i like the specs, but how is the screen performance in direct sunlight, because 40% of my time is spent outdoors.
It's like most phones where its hard to see depending on how its hitting the phone. That being said if you are getting a real good deal this is a really good phone. So far I have not replaced it and I typically change every 6 months.
I was born in Darkness.....
As long as you have Auto Brightness on, then you should be fine. That is what I do and I don't have issues.

100% correct. I'm outdoors a lot and auto brightness makes the screen visible in direct sunlight.

I usually have auto-brightness turned off, as I like to keep my screen more dim to increase battery life. If I have to read it outside in the sun, I simply increase the brightness a bit and I can see the screen perfectly.

Best brightness app?

If you have an Amaze then you know that the secret to long battery life is minimizing screen brightness. Problem is the default auto-brightness levels are brighter than needed and there is no way to adjust.
I recently installed Lux which allows you to customize the auto brightness curve. This should theoretically extend battery life. I'll report what I find here on this thread.
Meanwhile one thing I noticed.... In Lux you can monitor the level reported by the phones built in light sensor. On my Amaze I get really strange readings. There are four levels: 90, 320, 640, 11000. Really? With careful shading of the sensor I was able to get a reading of 2400 once. 11000 was reported even in shade on a cloudy day.
But it seems like the sensor doesn't read light levels well at all. There isn't enough granularity and the calibration is way off.
Anyway if we can fix it or address it, that should make a real difference in the battery life of the device.

You can put a 'slider' anywhere you want and simply slide it up and down to change the brightness to the exact levels you want.
Works great an you can customize it quite a bit. :good:
It's shown in on the top in the screenshots at the link, but I always put it on the right hand side, a little higher than mid-way, and I make it translucent grey so you cant even really see it unless you're looking for it.
That's the free version, I have the Pro version and it's worth it. lol

[Q] What is the best brightness setting?

Seems a shame to keep this beautiful screen below 70% brightness. What is the best setting for brightness that won't kill my battery? Thanks.
Leave mine at 80 and make it a full day
30% and auto brightness. Greenify with firewall blocking most connections. CF lumen changes tones in the pm. Think im just lucky my eyes are more light sensitive so I can keep brightness settings low.

I use Lux Auto Brightness and my Day profile currently is set for max 70% and that for me is perfect even outside in the sun.
Try Lux if you haven't already.

Screen is great in full sunlight. You get max brightness if you turn off auto brightness and push the slider all the way to 100%. Guarantee you won't have an issue with that.
I stay at 40% no auto brightness. Usually not out in the sun often but when I'm I switch to 100%

I do sometimes miss the AMOLED screen from the S4 only for the Blacks though.
The bottom line though is this QHD screen is amazing. Even though it's the first of its kind for a phone, I think they did a great job. The detail you can see on photos and watching videos is just insane.

I'm coming from an HTC One M8 and idk, I'm just not sold on the display yet. Maybe just my eyes. I do find that auto brightness is always too dark for me inside.
+1 for LUX app, I have it in every phone and tablet in my stable, but...
I find the LUX auto setting to be much too aggressive in dimming the screen under most conditions. I often have to force it to add 30% or more to the auto.
Agree with post above about missing the inky blacks of an AMOLED screen. The blacks are the only complaint I would make about this beautiful display.
I like it @ 70 no Auto, with color correction on and the circle covering just a smidge south of center on the camera icon on the screen that you use to calibrate the color correction.
50% and auto.
For me, anything less that 80% looks awful. Yes, downright awful! At 80%, it looks great. On my G2 it was 70%, but the G3 needs more to look clean and bright. I'd rather have to charge the phone 20 times a day than suffer with dimly lit screens. Sometimes people spend more time trying to figure out how to save battery life than they do using their phones. Enjoy your phones people, and stop suffering over battery life!
That said, I do get a tiny blip of dimming when switching apps or screens. At a solid 80% it seems to auto dim a tiny bit during normal use. I think this is some sort of throttling function that is normal with the G3, but it is minor annoying. Some people had done some overrides to this but I can live with it.
