Pressure Sensitive Home Button - Samsung Galaxy S8 Questions and Answers

Hi all,
I love the pressure sensitive home button feature on the s8 and note 8. I have a few questions about this. First, is the entire bottom part of the nav bar pressure sensitive or only under the home button on the nav bar. My second question is about the vibration motor. Does it have 2 vibration motors (one for haptic feedback for the pressure sensitive display) and one for phone calls, alarms, notifications etc. or only one vibration motor. My second question is if the pressure sensitive display has its own API that can be used in developing apps exclusive to the s8 that takes advantage of it and can this pressure sensitive home button still be used on a custom aosp rom. Also does the pressure sensitive display trigger the vibration motor once or is it gradual, like the strength of the vibration motor increases as you put more pressure on the home button. I also discovered that there's this app called force touch by a creative developer named Michele Lacorte, and this app shows a number which displays a real-time number of the amount of pressure you put on your screen. This app works on my Moto G5 Plus and I know that it's possible to change the strength of the vibration motor on Android, so is it possible to make app that either uses the accessibility and the drawing over apps permission or root access to make an app which has similar functionality to the s8 or note 8 pressure sensitive home button. Thanks !

Poor touch recognition on screen corners

Am I the only one that seems to be having a major issue with this? It comes up more with the added on screen keyboard in 1.5, it seems.
The corners of the G1 screen do not respond to touch at all, and I find myself always having trouble hitting the keys on the corners of the virtual keyboard. Applications that require you to touch any corner of the screen with precision (ie tic-tac-toe) are annoying as well because it's difficult to get it to work.
Is there any fix in sight or is it a hardware limitation?
definitely a hardware limitation.
hardware limitation means: normal hardware limitation or limited due failure????
I only experience this problem with the right edge of my phone. The top, left, and bottom don't have any problems.
Touch also seems to be less sensitive when the phone is rested flat.
My phone has the sensitivity problem on the edges too (mostly on the right and top sides).
For example, it's almost impossible to drag an icon to the left screen, because it doesn't seem to reach the threshold area.
The protective screen (boxwave anti-glare) made the problem even worse, but since it's much more comfortable than the glass, I won't be taking it off.
The easiest way to test all this is to use the whiteboard application.
So, I ask the developers: Please don't place the buttons on the edges of the screen!
The worst apps in this regard I've seen so far were the Video player (don't remember its exact name, its seek slider was unusable), and the sudoku with the number chooser in the bottom. OpenHome's app slider has the same problem.

Fix to Disable Navigation Button LEDs

You know the four LEDs that light up along with the keyboard LEDs at the bottom of our phone? It pisses me off that Samsung wired these guys in with the keyboard and literally made it impossible to disable them using software fixes. And I've set it to 3 seconds but that just doesn't cut it. I want them disabled, permanently, until I decide they should be turned back on. Well, I took it to the next level.
Cutting a piece of black electrical tape to just fit over the four, bottom buttons, I place it over the LEDs and BOOM, they were gone. My eyes will no longer tear up when I'm on my phone late at night while laying in bed. No longer will the screen be set to a healthy, dim brightness only to be overpowered the four LEDs at the bottom each time my finger touches the screen.
The capacitive feature still works fine, and I've lost no functionality with this fix. I'd post a picture but I'm having some issues with my digital camera.

[Q] Vibration thunk

I have keyboard vibration turned on (SwiftKey) so I can feel when I'm hitting a key, and it seems like every 5th or 6th press, the vibration is stronger than the other ones, so it feels like the phone *thunk*'s in my hand, for lack of better description, and the vibration seems to reverb around the metal lining and plastic rear of the device.
Has anyone else come across this phenom with their phone?
I noticed that too. Solved it by setting vibration time to 8ms instead of below.

Just an idea, not possible probably: Single Tap instead of Active Display

Something that's been bugging me with my active display is where I have my phone mounted in my car to the right of my steering wheel. It's constantly popping up the time / active display when I move at all. I'm sure this is speeding up battery drain. It also happens a lot when I'm at my desktop at home and at work since I keep the phone nearby, upright in my keyboard's built-in dock or laying flat on the desk between my arms.
While I LOVE the idea, it would be nice to incorporate the option to have it activate via single tap instead of waving over or looking at the device. It comes up a lot when I'm not looking at it and not really waving over it. Any movement near it seems to bring that screen up and since it's not AMOLED, it is lighting every single pixel enough to worry me on drain. I've looked at displaying active display, but then I lose the entire convenience of not having to press the physical power button.
My LG G4 had a double-tap, but I think I would enjoy a single tap or something. Does anyone know of my options to disable the wave or looking at the phone waking but still have convenience? I swear I read there's an option to have it activate on movement of the phone, but not the waving detection... but can't seem to put that together myself.
I feel like a bit of a dunce... I disabled Approach for Moto Display, but left Wake screen when notifications arrive set to On Moto Display and moving the phone works. If I set that to Ambient Display or Off, then moving the phone does nothing at all. It's a temporary solution to my annoying issue, but still no response to a tap on the screen which would be the best option for those needing to disable Approach for Moto Display for whatever their reason.
One thing to make sure you're doing is that you are acknowledging notifications as they come in. You can swipe them tot he left or right to dismiss, but if you do nothing with a notification it will keep lighting the screen up every minute or so until you do.
I did not know this initially and was concerned over how much the phone lit up, after finding this out and acknowledging the notifications as they come in it's gotten a lot better.

Some Questions about Moto Display

Hi all,
i love the moto display feature but i have some issues that make it less usable for me.
- on certain conditions the moto display seems to react to fast, while on other i had to wave 3-4 times until the screen was woken up. Does anybody know what makes the display not recognize the wave sometimes?
- i hate the fact that the notifications are an all or nothing feature. i might have 10 notifications, and i can only dismiss them all at once. But i want to dismiss onlyspecific ones and keep the rest on my lockscreen. Is this possible somehow?
- as the moto display dismisses all notifications at once, and the regular android lockscreen doesn't, creates situations where there are notifications on the drawer (which need to be dismissed manualls) vs. the Moto screen that doesn't show any notification.
Is there any way to make the dismissing of notifications work as on stock android (possibility to either dismiss all, or only specific ones).
I'm pretty sure its a proximity and light sensor of some sort, but other than that, I'm having the same issues as you.

I believe that only the sensors on the top of the phone fact to the wave. I don't know what the bottom sensors do.
Why is it impossible to find a diagram listing the location and function of all of the sensors?
If you have many notifications and want to do each individually, then instead of using the moto display just hit the power button to go to the normal lockscreen.

Top sensor is for waving (as you said). Bottom sensors are there for when you pick the phone up. If you go to pick the phone up, once your hand covers those two sensors, the display lights up. I found this out somewhere on XDA because I had no idea what they did either lol.
you can disable the sensor, and it will work like the first generation moto x.
Still, the sensor works fine for me, they just takes a little time to turn on after the screen lights on (about 1, 2 seconds) so it's not instant.

Thanks!
I checked out the bottom sensors, and it appears that they do respond only to touch, as opposed to waving over. :good:
