Optical trackpad sensitivity - myTouch 4G Q&A, Help & Troubleshooting

Has anyone found where this is controlled? I've been fishing around in the /system partition, but no such luck as of yet. I've read that it has to do with the texture of the object with which you are touching the trackpad. Ie. We mechanics have rougher hands than those of us that are desk jockeys ;-) therefore causing a higher textured finger surface and better response from the trackpad. Personalization would be awesome to be able to individually tweak the sensitivity! Just a brain picker for all of us getting plastered on this lovely friday night...

tightness of slider

how tight is everyone's slider mechanism? If you grab the screen with one hand and grab the keyboard with the other (while closed or open), does it twist much?
I have a little play with the slider but its barely noticeable. I've come to expect this with all slider phones.

I wasn't sure if it was normal or not. Haven't ever had a slider. I'm not a huge fan of how the keyboard doesn't really "snap" open, but it's a darn nice keyboard to me either way
I've had mine in the blue/black case from radioshack since the 6th. In the case is has pratically no play at all, out of the case its just as awesome.
I was worried it being in the case might damage it, buts it great so far.

Mine's developed a little play when it's closed. By that I mean the screen can move slightly before more force is required to open the keyboard.
When the keyboard is open, there's also a small amount of play with the screen. The screen can 'twist' a bit if I push down on the right or left side.
Small annoyances but I'm not sure it would be any different if I took it back for a new one.
I never noticed the "new" plastic wrap thats on either side of the keyboard, after i removed it, the slider is smoother and more responsive. Feels really solid to me.
My wife's has never had any play at all. The slider feels smooth and crisp. Compared to my old Epic which would bend and move its quite refreshing to not feel like I could break the phone by opening it.
I'm going back to radioshack and trade my phone for a newer shift because it seems like my slider keeps getting worse and worse. And I also have a black hue at the bottom of my screen. Now I remember why I hate sliders. Lol.

Wow.. I cant believe I didnt notice it either until I saw this post... I was like, no way could I have missed that after using it constantly for 2 weeks. But there it is...
P.S. - seconds after posting I realized that the protective plastic wrap is not only on both sides of the keyboard. If you slide your keyboard out and turn the phone around, you will notice that the entire backside of the screen surface (where it reads "with Google") is covered in a large sheet of the same plastic. After all of the plastic is off there is definitely a noticable difference in the smoothness of the slider. Thanks again to stealthfx.

[Q] Slight Screen Wobble Normal?

Hello Everyone,
This post is, more than anything, just for peace of mind (and some of you will probably think it's not a big deal).
Anyways, I just got a Google I/O version of the Xperia Play and noticed that with the slider closed if I hold the phone with the micro-usb facing up, and tap on that edge of the screen, it will exhibit slight looseness. Also when the slider is open there is a very slight movement (but it probably wouldn't move unless you were testing it). I'm just wondering if all this is normal since all the reviews I've read call the slider one of the best ever made "solid as Stonehenge on a windy day" as one reviewer called it. Any thoughts?

Hmm mine doesnt shake
Sent from my R800i using XDA Premium App
mine kind of wobbles, if I push either corner up it'll wobble maybe about 2mm.
Every slider phone I've had wobbles a bit even the aino which was possibly the most stable slider I've ever used.
I was hoping that the xplay was a little more stable.
Yeah...maybe it's my inexperience with slider phones but I almost thought it would be completely stiff (like no wiggle). It's not like it's "shaking" persay, just that there enough movement when pressing it in certain areas, to make it noticeable. I finally found another thread on the sony forum which had a conversation about this...the crowd is divided on whether this is a manufacturing problem or just designed that way...
The problem seems to be that the hinges are at the very top (when the slider is open). So there is nothing holding it down towards the very bottom when the slider is closed.
I only see wobbling when the slider is closed btw, when it's open its very solid.
I think a long, thin rubbery strip underneath the analogue thingamajigs would stop a lot of the wobble. IMO
+1 mine wiggles a little bit
The side where the usb port is wiggles 1mm.

Little quirk of the s-pen

I've noticed something interesting with the s-pen. Having used a lot of phones that had a stylus, i am using the s-pen a lot. If I'm using the phone in bed and I'm lying down with the phone held above me, when using the s-pen, the phone will respond to the pen even if it's held up to a centimetre above the screen without actually making contact.
Anyone else noticed this? Still loving the phone though. It's clearly the best device i have ever had.

Mine doesn't do that. In fact, I can very lightly touch the screen with the stylus without it registering. I have to give it a little pressure. This is in any position. I saw a YouTube video of someone having the same effect you describe, though; I wonder if it's a stylus thing or a screen thing.

It's supposed to know the pen is there before it touches the screen so it can turn off the touch screen. That way your palm does not activate it.

The reason it is probably doing that is because of how Wacom technology is designed. To register interaction with the screen, the tip on the stylus is pressed down to make contact with the sensor inside the stylus. It then communicates with the radio inside the screen. So obviously if the stylus is held upside down, the tip will be making constant contact with the sensor. It could be that the stylus tip is slightly loose, so you should try another Wacom stylus.

I just confirmed this on mine. I used a piece of tape to hold the tip of my stylus depressed, and that caused me to experience the issue. Looks like some people have defective stylii.
Heard about it before

Also, if you change the angle of using the pen, the ink start from higher (not from under the pen)!

I would venture a guess that this problem is the underlying issue with the minority of people who complain that the stylus is inaccurate. I wonder if it would be possible for Samsung or someone here to create a calibration function so as to adapt to how the user typically holds the stylus.
Or we could go this route...
<apple>You're holding it wrong!</apple>
I think the offset of the pen is actually purposely added to look more natural in most use-cases, but occasionally manifests itself strangely, like at strange angles. Here's the easiest way to reproduce the weirdness -
Turn off auto-rotation.
In normal portrait orientation, bring up the S-memo quick note double tap thing.
Write your name (or whatever) along the bottom of the quick note, holding the pen as you typically would. Notice how the strokes are drawn.
Without closing that note, hold the phone upside-down.
Now write the same thing you wrote before, along what is now the bottom of the note. Notice how the strokes are now drawn.
The strokes are offset in the direction that you tilt the pen (non-inverted control scheme ), but is also offset very slightly higher up the screen that the pen by default. This is so as to look more natural in normal use, because of course the pen does not actually touch the area that it is drawing on; the glass is in the way. The effect stacks somewhat strangely, however, when holding it, for example, upside-down.

Interesting! I assumed people were seeing differences just because they were using the phone in different ways, but if you still can't see it by doing this, I guess there actually is a fundamental difference in different phones.
Was there a calibration thing when we first set up the phone? I don't remember anymore. BTW, I'm on KJ4.
No, no calibration thing at the beginning. Still hoping for one.
One thing i thought i should be clear on. The stylus works perfectly fine in all other situations and it's only if the device is angled in that way the stylus behaves accordingly. Personally, it's not a problem for me. I still see this as the best device i have ever owned.

Very Clever
I still think that if the galaxy note displayed a little dot while hovering with the pen, it would be much better. With all wacom devices on windows, with a tablet or a wacom layer above a screen, the dot lets you see exactly where the next stroke will begin.
When you use a wacom pen, you don't start your next stroke based on the location of the actual pen on the screen.
Even with perfect calibration you still have the parallax effect looking through a thick glass layer. Looking even at a slightly different angle will cause the pen to be off again.
Instead, you use the dot.
Hopefully someone will be able to develop something to put a dot or a cursor of some sort on the screen.

One hand operability

Just to quell any concerns of soon-to-be owners: It can be done. It can be used with one hand. I'm not a giant (about 6'1", slightly above average) and I'm coming from a 4S, so I'm not used to huge phones. You literally just have to grab it differently than you would a tiny phone.
I don't understand why all reviewers grab this phone like a murder weapon, and grip the crap out of it - and then try to use their thumbs to grab the adjacent corner of the screen. Wtf? Of course that's not gonna work. I can reach the top corner, but I splay my fingers across the bottom of the phone for better control. I'm sure the people who really love this phone and use it as their daily drivers figured that out within the first day and are happy as can be.
Long live the big screen.
I agree, in the beginning I found that it was a bit difficult to handle even with my large hands but as soon as I got used to holding it "like I'm supposed to", which took me like ten minutes, using it with one hand has been a breeze!
Now it feels weird to hold smaller phones, I tend to try to clench them with just my palm.
Hahaha that's exactly what I was doing earlier. They do start to feel like tiny toys

i think i may have to improve my dexterity on this one, lol.
But the thing is with smaller phone I can grip the other side with the 4 other fingers, while with my Note if I want to comfortably use it with one hand, my other 4 fingers can only slightly grab the back of the phone to allow my thumb to move comfortably (that is can reach the other side of the screen with my thumb), and I'm scared of dropping Note holding it like that

I have smallish hands but I can easily operate it with 1 hand but the 'safety level' of operating the device with my small hands is close to 0. Soon after I switched to land scape mode with the use of ADW EX and use the phone almost exclusively in landscape mode but with 2 hands mostly.
I don't really need it but people with one hand issues should try button saviour on market.
Sent from my Galaxy Note using xda premium
Haha yeah I know what you mean, I would say my safety level drops quite a bit. Walking around outside and holding it like that for a prolonged time wouldn't be the smartest thing to do..
And I don't know if it matters, but I bought the white one and what was supposed to be a glossy, slippery back actually provides a good amount of friction (for whatever reason) when I hold it.
I just bought the zagg shields for this, to hopefully add to that friction and not take away from it. I'd hate to put this in a case and have it be even fatter :/

Oh yeah, and in landscape, you can pretty much only hold it. That definitely requires two hands for input

Agreed, had it for a week now. All my typical things I use to do: one hand, in pocket, holding on to other things and phone, watching yottube in bed while falling asleep, music listening while doing other things so loose and simple touches - all work fine -- many better. There is something amazing that the larger screen ( see more, more is big, less zooming in and out) along with the real estate for interacting that this phone gives you - that is a game changer. Also the voice input tools are huge ( vlingo and gvoice) , work great with this build and dual processor -- so I am doing much more with voice ( most of my email writing , commands to get stuff or do stuff). And of course the best is the spen - its precision and accuracy are so MUCH better than touch. Touch is great for fast and casual, but sometimes you are sitting ont he couch or desk or standing leaning against a wall where you plan to do over a minute of browsing, scheduling, email answering - I find the pen rocks a these times. In fact see this page on xda, look at the smallest icons you want to hit ( next page, ...) I do not have to zoom for any of them, I can hit the all (like 1 pixel accuracy with the spen) - saves me huge wasted zooms and moves and misses. Love this phone - again it is a gamer changer.
I didn't have a problem using the Note with only one hand. But the problem is that if you're walking then it might drops easily. Si I found a great compromise, I bought a silicone cover which adds more grip. And it saved me once after I dropped my Note being on my bike. The Note didn't get any damage whatsoever.

I'm 5ft 11 and don't have particularly big hands. I have no problems using the Note one handed.
Like some others, it's more about adjusting your grip and supporting rather than strangling the phone! It is a little tricky to text while walking etc but it's do-able.
I've actually started finding other phones with their tiny screens and keyboards difficult to use! ;-)

S-Pen Sensitivity

So I'm in love with my Note. I bought my wife the N7 for books and social media, but I really needed a productive tablet.
My question is about the S-Pen. I've never used the Note "Phablet" or any worth while stylus so I'm not sure if this is normal behavior or not.
When using S-Note, I cannot start a little line with a light press, it requires a firmer press to "activate" then I can adjust. It will also sometimes "skip" when trying to draw thin lines. I don't believe I'm pressing to lightly, because when it does this it isn't as the lightest line width, I'd say the line represents medium pressure, skips, then picks up low pressure.
It is also not registering if the angle I'm holding it at is to sharp. Anything after maybe 25-30 degrees off center is unreliable.
Just wondering what experience others have, and if this is considered defective.
EDIT: Wrong section, sorry everyone. Mods please move.
Sent from my HTC One S using Tapatalk 2
Ive writen using many different angles and i havent pressed hard for it to show up you can change the width of the line in settings

if this can help you, i posted something similar a while back: http://forum.xda-developers.com/showthread.php?t=1876108
the answer is: you may have a defective unit. the nib shouldn’t move more than 0.2 mm. i got my Note exchanged, and th experience is now a bit better. sample variance could be quite high.
You may want to try switching out the tip to a plastic one. I get better results with that.
