Question Anybody using extra dim to reduce PWM? - Samsung Galaxy S22 Ultra

The S22 ultra is pretty bad for PWM and it does affect me, most phones are not great but the S22 seems worse than most.
How much of a solution is extra dim really? Are there any downsides to battery or even burn in? At the very least it would seem you would lose that extra brightness when outdoors unless you manually toggled it off which seems a bit of a faff.
Anybody using it?

[Q] app to increase max brightness on transformer

hi, unlike a lot of android users i dont have issues with my battery life. so one day i thought about my eeepc i have and recall that i have an app that has a feature to actually make my screen brighter. so its like: low-mid-max-ultra, when ultra makes like an 120% of the screen bright.
so ive started searching for that on android but with no success. anyone know some app that will make transformer screen even brighter then max brightness?
cause i can really use that outdoor, as we all know its very difficult seeing something with direct sunlight, more like impossible.
thanx by advance
I do not see why you would want the screen any brighter. even in full sunlight with the screen brightness setting on auto I can read the screen very well. far better than my laptop.

+1 I dont have any problems with sunlight here the screen is bright enough
I don't know if such a thin exists.
My guess is no.
wierd. well maybe its because i have a matte screen protector, although i dont remember been any different without it. anyways, i think it'll be nice to have the ability to brighten it even more because i think that we still not Exercising this ips panel full potential.
but thats only me...
Look into an app called "Lux (Beta)". I know it lets you get dimmer than stock - not sure about brigter (ask the dev - he's very responsive). Tons of other features as well. It does costs $.99, but well worth it, in my opinion - my auto-brightness now actually works!

I know this is a slightly old topic but I wonder if anyone found a working (and not too dangerous) way to increase the max. brightness?
look for an app called "Display brightness" by RubberBigPepper.
According to the Android developers guide, the brightness is adjustable from 0 to 255, so it's possible.

Is the screen resolution really that bad?

I'm hearing really negative reviews on the tab plus screen resolution as it's not great outside in the sun and it is unbearable. Is this true? Do you guys believe the screen resolution to be really that bad? Thanks.
The screen resolution has absolutely nothing to do with sunlight readability so I don't really understand what you mean here

Don't know if it's against the rules but one was from Cnet. Another user was talking about it as well. Don't flame me, i'm just trying to see if it's all hogwash per say because i'm really considering getting a galaxy tab plus.
the resolution is fine for my eyes. I don't quite get what all the hype about resolution is these days... My computer monitor is around 100ppi... Why do I need a tablet or phone that has 400ppi?
What about the brightness level. That's the issue I've heard some things about. People are saying that the GT+ is very dim and difficult to see outside.

I can't comment on that, really. 99% of my usage is indoors, and I might have to wait until May before there's another sunny day where I live. Then again, the only tablet-like devices I've ever seen that are actually good in the sun are e-ink devices (kindle touch, nook touch, etc)

Again, some sources for where this brightness issue is coming from would certainly shed some light (excuse the pun)?
I have to agree with garyd9 here. My tablet lives indoors most of the time. The few times I've been outdoors with it I was able to crank up the brightness to where I had no issue with seeing the screen. Typically I leave the brightness set between 20-35% indoors and occasionally to as high as 45-50% depending on the light in the room. In full dark I run it to minimum as its too bright. Maximum is insanely bright and I can't imagine many scenerios where I would need it to be that bright.
It should be noted that I don't use the auto brightness as it is wholly inadequate for the purpose. I imagine that users who are complaining of dim screens are relying on the auto brightness feature and not adjusting the brightness manually. Overall I find the tablets brightness to be more than capable of handling the job.

Thank you for your honest opinion. I guess that's what I was looking for earlier but maybe I was just misunderstood or something. But I thank all you guys for your honest opinions here.

You may also consider checking out the tablet in the store if possible. Stores are usually very well lit inside and should give you an excellent idea of the tablet's display capabilities.
For future reference so there's no confusion: your initial post contained contradictory information. You were asking about screen resolution when you really meant brightness. Which, as captnodegard pointed out, are two completely different things. It's helpful to use the correct terms when asking for advice. It's also best to cite sources when referring to other critical reviews, as some people may not have seen those reviews.
Good luck in your decision!

THIS TAB SUCKS!!!! (I'm referring to Ainol's Novo7 Tablet. haha).
Anyways, I have a lot of experience using the GT+ outdoors since i always bring it with me in my college. Most of the times i use it outdoors when the sun is in its full glory. I have a matte screen protector which is why sun reflection is not an issue. However, I have to increase the brightness to 80% just so that i can have a pleasant view on the screen. 60% brightness is usable but I love the colors when I'm using it with 80%.
I also notice that the back gets hot whenever i turn FULL brightness on. Which is why, i capped myself to only increase brightness to 80%.
However, I live in the Philippines where a 32 degrees Celsius (90 degrees Fahrenheit) is normal which could have contributed to the back heating up.
In my opinion, the screen brightness was too dim. Particularly in auto brightness. Compared to my Sony s and htc flyer, I wasn't impressed. Selling mine because of this and other disappointments.

so don't use auto brightness. did you even try disabling Auto Adjust Screen Power? It can be found in Settings >> Screen. It's different from Auto Brightness.

Thanks for your reply. I guess it's good to rant sometimes. You pointed out something I missed in your post ...auto adjust screen power. It has improved brightness a little

What "other disappointments"? Just curious.
I routinely use the tab as a TV in the car during traffic on my commute and if the sun is behind me then its essentially unwatchable at 100% brightness but aside from that it works fairly well.
I don't know how well it stacks up against other 7'' offerings except the Nook Tablet which I had tried out first in my hunt for 720p playback and the two seem similar in screen brightness.
I have noticed the 7+ does not feel as bright as my 10.1 but overall it works well enough outdoors and no screen except e-ink really works well in direct sunlight anyway.
I back up that last claim with testing done on:
Galaxy S and S II
iPhone 4 and 4S
iPad 1 and 2
Galaxy Tab 10.1 and 7+
The time I tried to use my laptop outside after I said "Gee it sure is nice outside"

The inability to customise mini apps, disappointing. This is available on 7.7. Also, the peel application is unable to control several of my devices...e.g. found no support for VCR. Found Sony S much better for this. Poor position of power button allows frequent accidental activation whilst working with device. I admit latter point could be due to my own clumsiness

Thanks for the comeback. All very valid points.

can we be real?

We all know nothing is perfect. So please besides camera issues and ghost touches can we please list and talk about the things we do find negative about this phone. No bashing just true input. My phones on It's way and I don't have it til June 10th but want to know what to expect or look into
Curved display glare
Chinese users reporting issues with pop up camera not working
Dust inside pop up Camera housing
Phone too heavy
Too big
Uneven weight distribution
Piss poor adaptive brightness
Piss poor quality, my device already has abrasions from regular use in a case and gentle use.
The slider for ring, vibrate and silence is easy to move when putting in pocket, the one one the 6t was lot more firm didn't have that issue.
Bluetooth audio crackles (might just be my device)
It is a beast, in isolation not so bad but pick up an S10+ and the Samsung looks and feels small in comparison. Also agree re the distribution
No always on display
No wireless charging
Camera is just ok
No face unlock. Yes I know it does actually have it but IMO popping the camera every time you want to unlock is enough of a hassle for me to not bother
FPS is 2D and not secure (it is though super quick and accurate)
Tap to wake and raise to wake do not always work
I love it though!
Good:
Love the display and curved edge
finger print sensor is fast
haptic vibration is amazing
speakers sound great
Oxygen OS is great
unlocking the bootloader/rooting/MSM download tool lets me customise this device without worry
bad:
I think it's too big for my hands
camera quality is just okay (I think it's the same quality as my OnePlus 6)
If I'm honest, using things like Snapchat and messenger, the photos are amazing. It just using the camera app it's ****house.
Size is good, vibration motor is good. Sound is good. Screen is amazing. Seems any issue I have is really a software update away from a fix...
Screen glare.
Phone tooooo heavy.
Battery is not better than the 6T
The curved screen isn't horrible. Didn't think I'd ever get a phone with a curved screen, but, the curve is to much that it curves in the normal screen area. Needs to be a more subtle curve.
Adaptive brightness isn't as bad as some people say on my phone but it certainly can be improved.
Battery is amazing. I'm getting at least 20% increased sot then my OnePlus 6. This is with auto res, 90hz and screen on auto brightness.
Too big, too heavy not for me.
The pop up camera I do not see as problem, rarely use it.
The curved display is annoying more than once screen elements I need to interact with were on the edge. "annoying not a deal breaker"
Same thing about Qi charging not having it is "annoying but not a deal breaker"
My biggest problem is not the size of the phone but the thickness.
If it was the same thickness as my S10+ and maybe a tad lighter it would feel so much better in the hand.
Don't get complaints about it being too big. It's a big phone and bigger than the 6t, pixel etc. You would have known that before purchasing. Like me buying a pixel 3a and complaining it's too small ...
But I wouldn't buy it because I know it's a small phone ?
Pros
Screen is AMAZING!
Battery Life is awesome!
90hz!
Better additions to stock Android!
Multiple options for gestures!
Drawing gestures are 100%!
Cons
Updates are very slow to roll out and we are always the last to receive them. (T-Mobile variant)
Rare accidental touches on the edge.
Camera resolution is overall OK. (Coming from my Pixel 3 XL, this really isn't a fair comparison)
Dialer app is not as good as the Pixel 3.
Dual stereo speakers could be a better.
Accessories are very expensive.

Agreed.
Complaining about size and weight is useless. These were known. Curved screen yep. Don't complain.
The glare from the curved edge is an issue in some cases.
I don't have any real complaints.
I'm a realist and nothing is perfect, definitely not tech related products.
Loving all the input but for those who day heavy what phones are you coming from? I have a LG g6 ATM and with the case I use more often than any other case it weighs in at 226g so ok think that the OP7 pro wouldn't be that much heavier with a decent case on it. I'm mostly upgrading cause ALWAYS wanted a OP device on Verizon but the 6T just didn't sit with me well. Also I was going to buy a $300+ tablet for my photo editing but I figured the OP7 pro is large enough and better use of funds.
This phones adaptive brightness is meh.
When it hits ultra high brightness it can appear washed out.
The haptic motor is still meh.
Otherwise a great phone.
sad adaptive brightness (should be fixed with software)
screen could be a bit brighter when outside.
stereo speakers sound better than my pixel 2 xl
camera is good but not as good as my pixel 2 xl
small things, nothing serious. I love this phone and its the best phone overall that ive ever owned. To each their own though right? Something could be blatantly wrong with it or (what a lot of us do) if look for things to be wrong with the phone. No phone is perfect. There never will be, otherwise companies would go out of business.
I still rock the 6t, but have you guys noticed any difference in the camera after the software update "camera fix" on the 7plus?. In quotes because we all know OP has awful "fixes"
I like that it's big phone.
I don't have ladyboi hands so the phone is perfect for me. In fact I even have a bulky case on it which makes it even better.
As far as the camera goes... I have a Sony a7r iii for pictures. I will probably never even use the camera on the phone.
People that buy a "phone" and piss about not being able to take glamor shots with it are annoying.
I do play games though and I can definitely tell the difference between this device and my 6T. The 7Pro plays all my games amazingly.
I run 2 businesses with this device and have zero hiccups.
I don't have ghost touches.
I don't have a problem with curved screens.
Is it perfect?
Good enough for me.
Maybe not for you.

This is Rich as over the last couple years people have been screaming to make the phone a bit thicker to accommodate a larger battery as they'd rather have more battery life. Now people are b!tching about A SLIGHTLY thicker phone with a larger battery and it's only thicker by roughly 1mm!?!?

DC dimming

Greetings all
I want to know if dc dimming actually helps.
I have problems with oled screens giving me massive headaches. Please if you dont have issues or dont believe that pwm effects people Dont Comment.
I am not new to using phones at all, but as Ive gotten older my eyes have gotten more sensitive and technology has gotten so much better, Ive been very limited in my choices when it comes to new phones. I had the 1plus6t and absolutely Loved it, unfortunately it was the worst for me as far as causing blazing headaches and actually feeling sick. I am very interested in this phone so if you have experience with pwm and with dc dimming, let me know. Thanks!

I am sensitive to screen flicker too. I couldn't use amoled screens before oneplus 7.
Dc dimming definitely works and it helps (at least for me). It doesn't eliminate PWM flicker completely but makes it much more tolerable.
It doesn't give me headaches, but the OnePlus 7 screen hurts my eyes like crazy. DC dimming doesn't help.
However it does appear to show less flickers when taken with my camera. It still shows a lot of flicker at the lowest brightness settings.

Unusual eye strain on Mix 2S?

I have used a number of other phones, typically I'm a moderate phone user, looking at phone about 1-2 hours per day.
Since I bought the Mi Mix 2s, I often feel eye fatigue and light headache after looking at the phone. I tried reading mode and automatic brightness on and off. But it seems not helping much. If I reduce the time looking at the phone, it helps.
This never happened to other phones I used in the past.
Not sure if it's just me or a common thing for Mix 2S?

I've been using this phone since June (~3-6 hours/day) and never had any problems with eye fatigue or headache... Did you try filtering blue light?

Thanks for confirming. Yes, I tried reading mode on with warm color, but seems it didn't help much. I guess could be my eyes are sensitive to something on the Mix 2s screen (like PWM or sth.)

I don't think PWM is the problem. Notebookcheck.com tested this phone and they wrote: "Some PWM flickering occurs in the IPS display, but only if the brightness is reduced to 36% or lower. At 1168 Hz, the PWM frequency is very high, so that even a sensitive person should not feel any impact from this."
I had the same issue with mix 2s, it was the black version and the screen was a little bit yellowish. It was very unpleasant to look at. Now having another one, I don t seem to be having the same eye strain. The new one is the white variant.

Mine is a black version too. Maybe screens are manufactured by different vendors for different batches/variants.

I do get eye strain when using it at low brightness especially at night, I feel like my eyes have to focus really hard when the brightness is low. But that happens only with the mix2s, on samsung phones for example, I have no issues at all.
Try to keep the brightness at values higher than 30%, for me it helps immediately.

That's probably related to PWM. I also found that turn off automatic brightness could help a bit.
