Is it possible to calibrate the touch screen for use with the s pen?
When using the pen my note seems to 'write' about 1-2mm above and slightly to the side of what i'm actually doing.
Makes things like drawing even reasonably accurate shapes/lines etc near impossible....

My note also does the same and mine every note does the same and unfortunately touch cannot be calibrated in any android device(I may be wrong though)

have you tried changing the "dominant hand" setting under spen options in your phone's settings menu? if that still doesn't work try Touch Screen Tune from Market.....the developer also has a thread on XDA for this app as welll.

this is how to calibrate (read that several times in this forum and also works for me and other people:
enable auto rotate > open e.g. smemo in landscape view > draw sth with the pen and touch all the corners and edges with it > rotate back to portrait > now the pen should work accurately

I need to try this next time. When I had this problem I started the Note in recovery mode and wiped the cache. The pen then tracked fine again.
Hi
I don't know how to explain it but back on GB there were some shortcuts like touching the upper screen and moving left or right to change brightness but this seems to be gone on ICS?!
Are there any other things like this that have changed??

yeah it is gone on ICS
edit:
there is other things like display all animation menu, it is no longer there.
hidden gb pictures also replaced by uglier ics picture.
the easy copy paste feature also replaced by a strange hard to guess one
edit2:
This is more,
ICS is using more processor power,
ICS is using more ram,
ICS is using hardware acceleration,
ICS is slower in data read and update because of new sql file storage.

what was display all animation?
and hidden gb pictures??
but ICS is very smooooth and even though ram is normally 500-600 mb but there's no lag.
But the Brightness shortcut has to be there somewhere
And I somehow managed to take a screen shot without sweeping my hand across the screen?!Idk how I did it lol
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

Yes - Disable Recovery flash

which reboots if you "go back" what is this?

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!

Hello from Germany,
my Nexus is unlocked and rooted
Terminal:
su
cd /sys/devices/tegradc.0/smartdimmer
./enable
"Permission denied"
change user rights:
chmod 744 enable
(old settings are 644)
./enable
./enable[1]: 1: not found
so where is my fault?
ever since i disabled this gamma destroying feature and my screen keeps getting better and better
starting to fall in love with it really

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 its an LCD battery saving feature and so disabling it will definitely reduce battery life
choose between battery life or quality display

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...

I read that some peoples have issues with the touchscreen sensitivity. I've thinked i've got the same problem until i activate some developers options Options: "Show touches" and "Pointer location". Thereafter i realized that the touchscreen is perfectly responsive, the only issue is that when i click somewhere, my finger sometimes slip a bit and the touchscreen take it as a Swipe, then i have to click another time. The TF701 have a high density PPI (300) and it seem the touchscreen is not calibrated in accordance to that density.
By example (I don't know the real values!)
on my Motorola XOOM (150 PPI), the device need at least 30 pixels movement to detect a swipe = about 2/10 inches
on my TF701 (300 PPI), the device need at least 30 pixels movement to detect a swipe. = about 1/10 inches
What do you think about it?
Is it tunable by an application?
I found TouchScreenTune on the PlayStore but have never tested it since it's not marked as TF701 compatible, and i'm not root.
I found editing the following options makes a huge difference.
In the build.prop add the following lines:
Code:
# Improve Touch Pressure
touch.pressure.scale=0.001
ro.min.fling_velocity=90000
ro.max.fling_velocity=200000
Obviously the first line is just a comment
Also you can speed up browsing by enabling debugging mode in the browser by typing the following in the address bar
Code:
about:debug
Then go to the settings and the new debug menu and enable:
enable hardware accel
enable cpu upload path
enable light touch

Or just unlock and flash CROMi-X for all these and loads of other tweaks built in
Is there a way to change these settings without flashing a new ROM?

Well you need to be rooted but yes just follow the instructions above. The browser set won't stick on a reboot though so you'll have to keep doing it.
I am looking for a way to increase touch sensitivity on the S6 - like you can on the S5 - Note 4 - etc.
Cant find it - am I blind or is it missing? Normally it is located under "display" but I don't see the option there - Suggestions?
I don't think it's enabled. I'll look around and see what I can find. In the mean time you can flash @ktoonsez kernel. I believe he improves things in that area.
You having issues with your touch sensitivity?

Couldnt tell if you were making a funny or if you were serious.
What I am trying to do is have the option to use my stylus on the screen - not all the time - just sometimes - with increased touch sensitivity on the S5 you can do that - I would have thought they would have done this on the S6 -
anyone know if there is a way to be able to use Stylus on the S6?
Do you really want to increase the touch sensitivity? I actually want to decrease the touchscreen sensitivity of the S6. The touches is registering as swipe instead of single touch. Sometimes when I type fast it register as swipe. Want to know what I mean, download the app 9gagtv and try to click on the video cards to play the video.
I think the option is either gone or disabled because I couldn't find the option for it either
