HD2 rotation options and keyboard anomalies

i've searched for ways to open up other rotation angles as well as autorotation for any and all apps under the sun. most people suggest bsbtweaks and it really does do the job, but only rotates to the allowed 270degrees angle (thats -90degrees). effectively, it just adds the window class to the list of window classes that the built in HTC g-sensor mechanism will give respect to.
so i looked some more and found "changescreen" to fit the bill. after setting up exceptions, it works quite well to allow all other applications (except for the exceptions which include sense) to rotate to 90degrees, 180degrees (this looks way cool some times!), and the usual 270degrees.
HOWEVER, the point of this new thread is to discuss something that seems to be quite an attractive option if it can be made to work 100%. i've noticed that the onscreen landscape keyboard is MUCH more usable in the 90degrees rotation. this is because those damned cursor keys take up 0.5 inch of space that is balanced out by the hardware keys on the other side, thus placing the rest of the keyboard SQUARELY in the middle of your thumbs! contrast this with the experience on the default 270degrees rotation where the cursor keys and hardware keys end up on the same side, forcing the user to stretch out the right hand thumb to reach the middle of the keyboard.
the amazing thing is that keyboard really works 99% properly in the 90degrees orientation. the 1% catch? the little preview squares that appear while tapping a key seem to be using a buggy rotation matrix when the screen is in this angle! effectively, this makes the preview squares upside down and on the wrong side of the center line of the keyboard!
so for me, TWO things would make life much sweeter on the HD2:
1. keyboard preview squares should appear right side up and on the correct area near the tapped key in 90degree rotation.
2. i would also like to DISABLE the 270degree rotation altogether and force the HTC g-sensor mechanism to think that the 90degree rotation is DEFAULT. i know i can achieve this partially using "changescreen" but sense will still rotate ONLY in the 270degree direction in the album and music tab. with this tweak, one can rely on the built in mechanism and also be able to enjoy the keyboard in the more comfortable 90degree rotation.
any 1337 h4x0r222 with some 1337 suggestions/tweaks?

some updates...
first, there is another anomaly i didn't notice before pertaining to the thumb friendly scroller that pops up when touching a scroll bar. this popup scroller is also being drawn upside down and on the wrong side of the screen in 90degree rotation.
other updates include:
1. tried toggling HKLM\System\GDI\Rotation\LandscapeMode from 0 to 4, followed by soft reset, no joy!
2. tried toggling HKLM\System\GDI\Rotation\LandscapeFixed from 1 to 0, followed by soft reset...the right handed and left handed options in Screen under Settings->System become available but the g-sensor autorotate doesn't seem to respect the choice set here, so no joy!

[Q] Quick touch input question

On the capacitive screens, can you tell how much area is being touched by a finger or stylus? The reason i ask is that maybe some rudimentary sensitivity could be implemented for drawing apps.
Thanks,
-Dustin-

Actually "yes", but you have to handle the event by your self. You can even see how much different fingers are touching the screen...

http://d.android.com/reference/android/view/MotionEvent.html#getPressure(int)
and

However, the values aren't well defined so you'll need to self-calibrate somehow. Also not ever touch screen supports this, even if they are capacitive.

Pressure Sensitive? Doesn't work

I keep reading on here that the S Pen is meant to be pressure sensitive.
Well, on mine if I lightly stroke it across the screen nothing appears. Sometimes the line may start about 3 cms across, which is pretty useless.
I have to apply quite a bit of pressure to draw a line or write, which totally defeats the purpose of the so called pressure sensitivity.
Is there any way of testing this out fully?

Get the exact S-Pen pressure live value
I don't know if you can apply this on default ROM, but on all ICS custom ROMs i tried so far, there is an option:
Enable:
Settings > Developer options > Pointer location
Now you will see a crosshair showing the position if you touch by finger or by S-Pen. In the upper end of your screen you'll notice a transparent bar, showing some numbers. The far right one "Size: " is just for finger actions, which will meausre the size of the finger/surface you put on the screen. One number left "Prs:" means pressure. You will notice, that you can slightly press with your S-Pen and vary the pressure value from 0.01 to 2.5
All apps which recognizes this number are so-called "S-Pen pressure sensitive".
The thing I've noticed is that neither S-Memo nor any 3rd party S-Pen compatible app will resolve this number to more than two different pressure levels:
low pressure, high pressure. At least S-Memo, FreeNote, SuperNote, Jotter and Infinite Paint do only differ in these two modes. So a line can be thick or thin, but nothing between. That's NOT what I expect of those apps! They can read the pressure value out by the API, so why don't they resolve the value completely?
Using
Code:
if (pressure<1.0) {line.thin} else if (pressure>=1.0) {line.thick}
isn't cool!

Noticed the same thing here.

Very interesting because I always thought the Note was "technically" limited to 2 pressure levels, but apparently it's not. Now, which apps (note taking, drawin aps) take advantage of the true range of pressure levels ? It would be nice to know.

Papyrus seems to work better and recognise pressure more. Convinced it works correctly after using that.

I can also see this (using midnote1.0), very interesting. However I can only get it to go from 0.0 up to approx 0.80.... I am not comfortable to press any harder with the s-pen, for fear of breaking it.
edit- it is also interesting to note that when using your finger, the pressure reading is dependent on the area of your finger touching the screen....whereas when using the s-pen it is dependent on the true pressure applied.

+1, works better than the standard s-memo app.

[Q] One-handed operation

I only tried to use this feature on my S5 a couple times, but my wife would like to use this feature on her new N4. I find that starting the One-handed operation function on both the S5 and N4 using the touchscreen gesture described in the enabling setting screen rarely works. It takes a bunch of swipes before the reduced One-handed screen appears.Very annoying and defeats the purpose of the feature as you actually have to try to enable it using two hands. I didn't even try to master using this feature given that it's so hard to get it started. I thought it was an issue with my S5, but after trying it on the N4... I had the same results. Is there a shortcut to enable this feature other than that the swiping gesture? Anyone else experiencing this issue?

Im sure you dont swipe correctly, for me it work all the time, just swipe your finger from screen edge to the middle then back to the screen edge with a horizontal way! Its not a V-like swipe, its like a hohorizontal "I" swipe just try it until you get it working!
Good luck!

Yes, I'm swiping correctly, but it's not very reliable it works only 1 out of 6 or 7 times. I have a wallpaper with a straight line down the middle and I swipe over that straight line to the middle of the screen from the edge of the screen and back. Of course in a horizontal I. It would be nice if this feature had a toggle in the top bar pull down to turn it on/off. I'm hoping a Xposed Module developer notices this deficiency and comes up with a module with shortcut solution.

You have to start at edge of screen then finish at edge of screen, which can be a problem if you have a case. Doesn't hurt to actually go past the center either.
I can do it pretty consistently, and the times I fail I know it's because I hit the rim on the case and didn't swipe all the way to edge.

Problem with "overly sensitive" touch screen; registers fingers just by hovering it

Problem with "overly sensitive" touch screen; registers fingers just by hovering it
I changed to Lineage OS 14.1-20170412 yesterday, after having had an about 1-year old Cyanogenmod stable on it.
Now I got a smaller issue with it; I'm pretty sure it didn't do that right away after installation.
It started to register my fingers when they are already hovering above the screen, like 2-3cm away from it. It feels like a proximity sensor, just all over the screen, not turning off the screen when you get close but creating graphical hover effects:
When I'm in the Android settings for example, the settings category rows get a gray back color.
In Chrome, links get underlined when hovering them from far away.
The quick panel creates white bubbles around the tiles.
While this isn't causing any misbehavior (I can't actually press anything of those things by moving my finger up to 3cm towards the screen, and then moving it away immediately), it's visually annoying.
I did not do anything special since it started to happen, and already checked on the following:
- Glove mode is not turned on.
- There's no other "Accessibility" stuff turned on.
- When showing tabs in the developer options, it does not register it as taps, and does not start drawing a line when hovering the finger around on the screen.
Is there any way to "recalibrate" the "sensitivity" or turn this thing off it's a feature and not a bug?

Check Settings > Air view. I'm not sure about custom ROMs but on my stock ROM this is what causes the links in Chrome to get underlined when hovering.

I indeed found something in Settings which i must've accidentally enabled: Language & Input > Touchscreen Hovering (under Mouse/trackpad). When it's on, you get the effects I noticed, so i turned it off.
