About to pull the trigger on two 4xls. Looked at a Verizon version at Best Buy yesterday which was not in "demo mode" like the one on the Google stand. I couldn't see any toggle to bring the screen resolution down to a 1080p or equivalent ratio to save battery. Did I not see it?
I also couldn't see double tap to wake and shut options like on my current oneplus 6t that I have gotten very used to. Any luck with that?
There is no toggle to bring down the resolution, but with a few adb commands (you'll have to enable developers options) you can get it down to 1080p
adb shell wm density 444
and
adb shell wm size 1080x2280
Double tap to wake is there. If you are open to using a different launcher, you can use double tap to turn the screen off without hindering the biometrics. Both lawnchair and nova launcher support this within their gestures submenus.
There's not much battery saving, if at all, with lowering the screen resolution.

Thanks. Can I assume that enabling developers options is enough and no need for root? I will surely give it a try if I don't have to root.

That was interesting. I guess if screen is made QHD there's no sense in throttling it down to FHD.

THE PROBLEM
To save battery while playing video Tegra intelligently decreases the backlight while increasing color brightness and contrast. Because it monitors on a frame by frame basis the changes are often unnoticable. You basically end up with the same displayed image using less backlight.
Unfortunately it seems to get stuck even after you leave the video and the changes are very noticeable as the changes were specific to the video frame you just left and not your homescreen.
This also may be the cause of some ghosting issues and for some it seems to eliminate any ghosting problems for them.
MANUAL FIX
(will reset at each reboot)
In terminal -
(You may need to type "su" and press enter before entering these commands)
To turn it off
echo "0" > /sys/devices/tegradc.0/smartdimmer/enable
To change how aggressive it is (untested)
echo "#" > /sys/devices/tegradc.0/smartdimmer/aggressiveness
Note: battery life while watching videos WILL decrease if you turn it off or decrease the aggresiveness
AUTOMATIC FIX
Trickster Mod
- has the ability to disable PRISM and set it to disable on boot.
N7scripts.rar
- A collection of scripts compiled by hamdir which, in conjunction with Script Manager (available in the market) will allow you to toggle smartdimmer/PRISM on and off at will.
- You can also use script manager to toggle it at boot if you want.
- Also includes a script to disable 3D scaling which may improve 3D gaming performance (untested)
Thanks to hamdir for his pack of scripts and for convincing me to make a new post for these fixes.
I may use this for other sysfs tweaks... mine for now.
Thanks. Easier to save and flash then manually entering in these values each time I crackflash.
If the T3 can increase the color saturation and gamma while decreasing backlight, wonder if we can increase the colors while leaving the backlight alone. All of the N7s I've played with have a dull washed out look with a warm tone for whites.

does flashing the .zip just delete the PRISM file? cuz when I manually enter the command after flashing it via CWM it doesn't allow me to any more.

ROM may flash stock recovery on boot? Fix?
No

How do you set up the script? I have script manager and the Scrip.rar saved onto my SD card. Thanks in advance!

Messing with the kernel I haven't had any luck. You could ask Morfic. He might be able to make something happen.
Also prism increase color BRIGHTNESS for the most part (you said saturation). That's why the homescreen ends up looking washed out and bright and not oversaturated when PRISM fails to shut off.

There's no prism file. These tweaks are changing a sysfs value. There's no file. The flashable zip adds an init.d file that runs the manual command at every boot.
In your case CWM is complaining about a file that flashes stock recovery on boot and overwrites CWM. These are completely different things. Let CWM "disable recovery flash" and you'll be good to go.

This is awesome. It definitely needs to be implemented in a ton of ROMs
so does flashing this decrease battery life when watching videos? im confused by op..
awesome post, thx!
yes this fix, completely get rid of the grey levels washout issues!!! and greatly improves the quality of the display, it will cost some battery life, but any boost to this average screen is welcome
now about ghosting it did reduce it a lot but sadly it didn't kill it, i still get the very random occasion of faint LCD ghosting
finally we really need to find out a way to fix the stupid low saturation, in particularly the greens are very low
google....these screen issues, lack of tablet UI and launcher rotation issues, makes want to smash it through the wall
Nice find. Hopefully Google/Nvidia/Asus will fix this in an update.
Thank you very much for this! While I don't own a Nexus 7, I *do* own an Asus TF700T and this problem also exists on it. On the TF700, this "mode" is active all of the time, no matter what you are doing and it is *very* noticeable and distracting, especially when watching videos (but it *is* noticeable everywhere else as well).
Disabling this "Feature" makes the problem go away. At the very least, you can enable/disable as needed now.
Thanks again!

Care to post how it should be done then? Might be a little bit more helpful
Also, does this affect battery life overall? Or just while watching movies?

You do not "run" the "enable" file. You need to do this:
echo "0" > /sys/devices/tegradc.0/smartdimmer/enable
or
echo "0" > enable (if you are already in that dir).
That will disable the SMartDimmer "feature". Echoing a "1" will re-enable it. I have not noticed any battery life difference....

Yes as said in the OP smart dimmer analyzes the video frames and determines whether it can lower the backlight while increasing the color brightness and maintain almost the same image. Lower backlight = better battery life.

After I turned off the dimmer, the screen got a little brighter, so I manually turned down my normal 40% brightness to 30% brightness. So in the end I don't think I'm losing any battery life at all.

I agree - I think any battery life reduction will be *very* minor for most people... I certainly haven't noticed any difference...

Go into your phone's settings, go to "About Device" and click on Build Number 7 times to enable the Developers options. Go back into the settings menu and go into the Developers options. Scroll down until you see the following:
"Transition Animation Scale", "Window Animation Scale", and "Animator Duration Scale".
Turn all three to "Animation is off".
These will GREATLY improve your rotation time (as I've personally experienced) as well as the phone's speed itself. Animations will still be noticeable, so do not worry.

I found the issue. I had smart rotation on, which forced it to check every time it rotated if my eyes had changed orientation. Once i turned it off, rotation was instantaneous.
Thanks for the extra speed boost tip, though; made everything just that much quicker!

An old tip carried over from the GS4.
I do not see it in the device maintenance > battery section as demonstrated in some review videos? Am I missing something?!? Thanks.
you have to go to settings than display and go to content scaling and select small
Thanks, but I meant the battery saving feature of scaling the screen resolution to FHD or HD...In addition to other features that I cannot seem to find?

I've already scaled down my resolutuion to HD 1080p. Actually the proper instructions are to pull down the toggle screen, then touch the arrow or hold down the power savings icon. At that point you will simply have options to choose between Med or Max power savings. The medium toggle with be defaulted to the scaled down 1080p res, however you can customize these settings to your particular liking etc....
If your using package disabler pro. Just make sure device maintenance is unchecked. I had the same issue

I can't get the toolkit from the other thread to recognize my device worth crap. Rooted/TWRP'd, Xposed all working fine going the manual way. I would really like to scale things down on this large beautiful screen to gain more content space though. Anyone have any ideas?

You can always edit the DPI in build.prop but that will likely cause scaling issues. It does with the OnePlus 3. I imagine it would be the same with the 3T. If you want to just look for ro.sf.lcd_density. I'm pretty sure stock is set to 480, just set it to something lower like 400. There is also the per app DPI changer for xposed. You would have to set each app manually but you could set the ones that didn't work properly back to the stock setting.

Build.prop is the best method. Make sure to create a backup before editing though.
If you're rooted I recommend Le DPI Changer from the Play Store. Make sure you tick the "Use Shell WM for setting DPI". I have mine set to 400 and love it. There are also adb commands to achieve this without root but not sure if they'll work on the 1+3t
I use Easy DPI Changer from playstore and it works perfect...

Le DPI Changer failed on all normal settings minus the Build.Prop edit option. Confirmed that build.prop does work though!!! But same issue for me with the quick settings on OOS being misaligned, a bit shifted left. It's actually quite a bit left at 400DPI.
Any fix to this?
yep also getting the left shift. long press power you'll see the power off and reboot icons are messed up too. but that's about all I see. small price to pay. i don't mind it

Worked for me with "Use Shell WM for setting DPI" toggled but yes, shifts the quicksettings to the left here as well. Android N-ify Xposed module doesn't change the quicksettings either so I assume they've done something to add the quick toggles..

You would have to deodex the OPSystemUI.apk. Decompile it and modify it. Someone did it for the OP3. I can't remember if it was on XDA or the OnePlus community though.
Edit: That's what I meant when I mentioned scaling issues.

Which DPI setting would be better? Samsung sets it to like 411dpi iirc, but for example http://dpi.lv/ shows it should be 522dpi for 6,3" screen with 2960x1440 resolution.
What's your opinion on this? Maybe I'm wrong?

There is no "best" setting. Just play around with it and see what you like. The higher the number the smaller the content on the screen. I have mine set to 420.
Man 522 is small. I do like the layout but keyboard is way too small for my giant thumbs.
455 is best for me

I use 500dpi, perfect for me. however it breaks the samung keyboard, install Gboard instead
I love small font.
since the original was 411, I adjusted to 512, and increased to 564 recently.
Loved it.
did anyone notice any obvious battery drain after increasing the dpi?
